000651 BALB/cJ
Level 1
BALB/c mice are particularly well known for the production of plasmacytomas following injection with mineral oil forming the basis for the production of monoclonal antibodies. Although not all BALB/c substrains have been examined for plasmacytoma induction, substrains derived from the Andervont (An) lineage (which includes BALB/cByJ) typically are susceptible, while those descended from BALB/cJ are resistant (see: Potter M ,1985). Mammary tumor incidence is normally low but infection with mammary tumor virus by fostering to MMTV+ C3H mice dramatically increases tumor number and age of onset. BALB/c mice develop other cancers later in life including reticular neoplasms, primary lung tumors, and renal tumors. Rare spontaneous myoepitheliomas arising from myoepithelial cells of various exocrine glands have been observed in both BALB/cJ and BALB/cByJ substrains.

001303 NOD.CB17-Prkdcscid/J
Level 1
Mice homozygous for the severe combined immune deficiency spontaneous mutation (Prkdcscid, commonly referred to as scid) are characterized by an absence of functional T cells and B cells, lymphopenia, hypogammaglobulinemia, and a normal hematopoietic microenvironment. Normal antigen-presenting cell, myeloid, and NK cell functions are strain dependent. scid mice carry a DNA repair defect and a defect in the rearrangement of genes that code for antigen-specific receptors on lymphocytes. Most homozygotes have no detectable IgM, IgG1, IgG2a, IgG2b, IgG3, or IgA. Thymus, lymph nodes, and splenic follicles are virtually devoid of lymphocytes. scid mice accept allogeneic and xenogeneic grafts making them an ideal model for cell transfer experiments. Some scid mice will spontaneously develop partial immune reactivity. scid mice that have serum Ig levels greater than 1 ug/ml are considered "leaky." scid leakiness is highly strain depen .....

002216 B6.129S7-Rag1tm1Mom/J
Level 2
Mice homozygous for the Rag1tm1Mom mutation produce no mature T cells or B cells. Their phenotype can be described as a "non-leaky" severe combined immune deficiency (Prkdcscid/Prkdcscid) (Prkdcscid mice produce some B cells and IgM). They have no CD3+ or T cell receptor (TCR) alpha-beta positive cells. The thymus of the mutant mice contains 15 to 130 times fewer cells than heterozygous or wildtype siblings. The thymocytes are CD8-CD4- and most are IL2 receptor-positive. Neither the spleen nor the bone marrow contain any IgM or IgD staining cells, indicating an absence of mature B cells. These and other data suggest that B cell and T cell development has been arrested at an early stage. Macroscopically, the mutants are indistinguishable from heterozygotes or normal wildtype siblings.
001026 BALB/cByJ
Level 2

Although not all BALB/c substrains have been examined for plasmacytoma induction, substrains derived from the Andervont (An) lineage (which includes BALB/cByJ) typically are susceptible, while those descended from BALB/cJ are resistant (see: Potter M ,1985). Mammary tumor incidence is normally low, but infection with mammary tumor virus by fostering to MMTV+ C3H mice dramatically increases tumor number and age of onset. BALB/c mice develop other cancers later in life including reticular neoplasms, primary lung tumors, and renal tumors. Rare spontaneous myoepitheliomas arising from myoepithelial cells of various exocrine glands have been observed in both BALB/cJ and BALB/cByJ substrains. BALB/cByJ has a deletion in the Qa2 subregion of the murine MHC.

005557 NOD.Cg-Prkdcscid Il2rgtm1Wjl/SzJ
Level 2
The NOD.Cg-Prkdcscid Il2rgtm1Wjl/SzJ mice, commonly known as NOD scid gamma (NSG), do not express the Prkdc gene nor the X-linked Il2rg gene. NSG mice are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. Histological examination of lymphoid tissues reveals absence of lymphoid cells and some cystic structures in the thymus, an absence of follicles in the spleen and markedly diminished celluarity of lymph nodes. NSG mice are deficient in mature lymphocytes, serum Ig is not detectable and natural killer (NK) cell cytotoxic activity is extremely low. These mice are resistant to lymphoma development even after sublethal irradiation treatment. These mutant mice have been shown to readily support engraftment of human CD34+ hematopoietic stem cells and represent a superior, long-lived model suitable for studies employing xenotransplantation strategies. Please note that the NSG carries the tr .....

002288 B6.129S2-Ighmtm1Cgn/J
Level 3
Mice homozygous for the Ighmtm1Cgn targeted mutation are viable and fertile. Homozygous mutant mice lack mature B-cells. There is no expression of membrane-bound IgM, although some B-cells may be produced using a C gene other than mu. It may be useful as a model for B-cell immunodeficiency found in humans. Also known as muMT.
002650 B6.129S2-Il6tm1Kopf/J
Level 3
Mice homozygous for the targeted mutation are viable and fertile. No gene product (mRNA) is detected by RT-PCR analysis of lipopolysaccharide (LPS) challenged macrophages. Bioassay and enzyme-linked immunosorbent assay (ELISA) analysis of serum from LPS-challenged homozygotes reveals no detectable protein activity. These interleukin 6 (IL6) mutant mice show defects in responses to various viruses and in inflammatory responses to tissue damage or infection.

Of note, IL6-mutant mice may be available on different genetic backgrounds including mixed B6;129S2 (Stock No. 002254), C57BL/6J (Stock No. 002650), and BALB/cByJ.

007799 NOD.Cg-Rag1tm1Mom Il2rgtm1Wjl/SzJ
Level 3
Females homozygous for both the Rag1null and IL2rγnull mutations (and males homozygous for Rag1null and hemizygous for the X-linked IL2rγnull mutation) are viable and fertile. When compared to NOD-scid IL2rgnull (Stock No. 005557), these NOD-Rag1null IL2rγnull mice tolerate much higher levels of irradiation conditioning. Additionally, NOD-Rag1null IL2rγnull mice support higher levels of both human cord blood stem cell engraftment following irradiation-conditioning (leading to multi-lineage hematopoietic cell populations and a complete repertoire of human immune cells, including human T cells) and human peripheral blood mononuclear cells engraftment in unconditioned adult mice with respect to NOD-Rag1null (Stock No. For more information please see the full phenotype on the strain data sheet
002019 NU/J
Level 3
The two main defects of mice homozygous for the nude spontaneous mutation (Foxn1nu, formerly Hfh11nu) are abnormal hair growth and defective development of the thymic epithelium. Although the mice appear hairless, they are born with functional but faulty hair growth follicles. Hair growth cycles and patterns are evident especially in pigmented mice but the faulty follicles do not allow the hair to properly erupt. Homozygous pups can be identified as young as 24 hours by their lack of whiskers or poorly developed, crinkled whiskers. Nude mice are also athymic caused by a developmental failure of the thymic anlage. Consequently, homozygous nude mice lack T cells and suffer from a lack of cell-mediated immunity. However there is not a defect in T-cell precursors, and under the right conditions some functional mature T cells can be found especially in adult mice. Because of a defect in helper T-cell activity, responses to thymus-dependent antigens when d .....

002116 B6.129S2-Tcratm1Mom/J
Level 4
Mice homozygous mice for the Tcratm1Mom targeted mutation are viable and fertile. They are deficient in the alpha beta T-cell receptor. The thymus is devoid of CD4+CD8- and CD4-CD8+ cells. Normal numbers of CD4+CD8+ cells are retained without the IL2 receptor. There are normal numbers of CD4-CD8- cells. ~1% of the thymocytes express the gamma delta TCR. Mice may develop inflammatory bowel disease beginning at ~4-6 months of age.

007850 J:NU
Level 4
Outbred homozygous nude (Foxn1nu/Foxn1nu) mice are the standard in vivo model for drug efficacy testing in oncology. Nude mice are athymic and hairless as a result of the recessive nu mutation. T cell precursors exist but development is blocked in the absence of a thymus, resulting in an immunodeficiency that permits transplantation of tumor cell xenografts. Homozygous females are poor breeders and fail to lactate. Heterozygous males and females breed well and have normal immune function. Homozygous pups can be identified as young as 24 hours by their lack of whiskers or poorly developed, crinkled whiskers.
008215 (C57BL/6-Tg(TRAMP)8247Ng/J x FVB/NJ)F1/J
Repository- Live
Mice carrying the TRAMP (Transgenic Adenocarcinoma of Mouse Prostate) transgene develop progressive forms of prostate cancer with distant site metastasis, primarily to the lymph nodes and lungs. These transgenic mice express the simian virus 40 (SV40) large tumor T antigen (Tag) under the control of the rat probasin promoter. Expression of the transgene is specific to the prostate epithelium. Transgenic mice exhibit various forms of disease from mild intraepithelial hyperplasia to large multinodular malignant neoplasia. The median survival time for these F1 transgenic mice is 19 weeks, very few mice survive past 33 weeks of age, which is significantly shorter than the lifespan of transgenic mice on the C57BL/6 background. Comparative histological analysis of tumors from these F1 transgenic mice and from transgenic mice on the C57BL/6 background reveals that the tumors found in these F1 mutants arise from the dorsolateral and ventral lobes of the prostate and are more spherical, hig .....

Mice homozygous for the Ighmtm1Cgn targeted mutation are viable and fertile. Homozygous mutant mice lack mature B-cells. There is no expression of membrane-bound IgM, although some B-cells may be produced using a C gene other than mu. It may be useful as a model for B-cell immunodeficiency found in humans. Also know as muMT.
007750 B6(C)-Mir150tm1Rsky/J
Repository- Live
Mice homozygous for this targeted allele (miR150-/- or MiR-150-/-) are viable and fertile with normal development of T cells, follicular B cells, and MZ B cells. No miR-150 is expressed in spleen, mesenteric lymph node, and thymus of homozygotes. Homozygous mice exhibit B cell expansion (CD19+B220loCD5+CD43+CD23-; B1a subset) in spleen and peritoneal cavity (with reciprocal reduction in B2 cells) and enhanced humoral immune response (increased serum immunoglobulins of various classes both at steady-state and following T cell-dependent antigen exposure). Homozygous miR-150 deficiency also leads to enhanced induction of the miR-150 target protein c-Myb in activated B and T cells, but no reported change in expression of the miR-150 target genes Foxp1 or ZFP91 in resting or activated B cells. These miR150-/- mice may be useful in mircoRNA biology, specifically to study the role of miR-150 and its target genes (inc .....

008242 B6(Cg)-Gt(ROSA)26Sortm1(Ikbkb)Rsky/J
Repository- Live
Mice homozygous for the R26StopFLikk2ca conditional allele are viable and fertile, with a loxP-flanked STOP cassette preventing transcription of the downstream bicistronic sequences (a FLAG-tagged, constitutively active form of IKbkb (IKK2ca) and EGFP). When bred to mice that express Cre recombinase, the resulting offspring will have the STOP cassette deleted in the cre-expressing tissue(s); resulting in expression of the IKK2ca as well as EGFP fluorescence. Expression of IKK2ca leads to constitutively active NF-kappaB transcription factor activity. These R26StopFLikk2ca mice allow inducible expression of an activated form of Ikbkb (IKK2 or IKK-beta) and subsequent activation of the NF-kappaB transcription factor pathways.

For example, when bred to a strain with a Cd19 null allele and expressing Cre recombinase during the B lymphocyte development (Stock No. 006785), this .....

008449 B6(Cg)-Rag2tm1.1Cgn/J
Repository- Live
These RAG-2del mutant mice harbor a pan deletion of exon 3 of the targeted locus. Homozygotes (RAG-2del/del) are viable and fertile, with pan deletion of the entire RAG-2 protein coding region. Homozygous mice may be expected to have the same knockout phenotype as other RAG-2 null mutants or similarly created RAG-2 exon 3 pan-deleted mutants; with hematopoietic and immune system defects including arrested B cell and T cell development at the pro-B and the pro-T cell stages, respectively. These RAG-2del mice may be useful in studying the role of RAG-2 in B cell and T cell development (including cancer and toxicology research as a xenograft/transplant host), T and B cell receptor (V(D)J) recombination, hematopoiesis, hematology, immunology, and inflammation research.

005085 B6.129(Cg)-Cd44tm1Hbg/J
Repository- Live
Mice that are homozygous for the targeted mutation are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. No gene product (mRNA or protein) is detected. Although lymphocyte development appears unremarkable, irregularities are observed in lymphocyte trafficking. Tail-injected lymphocytes derived from null animals exhibit an impaired ability to traffic to peripheral lymph nodes, and to a much greater degree, the thymus. Transcription and translation of the targeted allele subsequently lead to the synthesis of the lacZ protein under control of the 5' regulatory elements of the endogenous locus in all cells and tissues normally expressing one or several of the CD44 isoforms.

In an attempt to offer alleles on well-characterized or multiple genetic backgrounds, alleles are frequently moved to a genetic background different from that on which an allele was first characterized. It should be noted that the phenotype could vary f .....

010635 B6.129(FVB)-Alcamtm1Jawe/J
Repository- Live
Mice that are homozygous for the targeted mutation are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. Embryonic spinal motor nerve bundles exhibit modest defects in fasciculation and, in some cases, abnormal axon trajectories form bridges or turn at right angles to adjacent nerves. However, adult motor function appears grossly normal. A similar defect is observed in retinal ganglion cell axons of the optic fiber layer, in which axons appear fanned-out and defasciculated with wide bundles. Homozygotes exhibit two types of retinal dysplasias characterized by photoreceptor cell evaginations or protrusions from the outer nuclear layer and retinal folding (invagination) inside the orb. The donating investigator indicates that this phenotype is less commonly observed on the C57BL/6 background. ALCAM is also believed to be important for immune system functioning, including T cell activation, and is a marker of tumor progression in numerous .....

006910 B6.129-Crkltm1Hkp/J
Repository- Live
While heterozygous mice are viable and fertile, mice homozygous for this targeted allele die in utero. Immunoblots from homozygous tissues show no protein expression from the targeted gene. The prenatal lethality exhibited by homozygotes on this C57BL/6J congenic background (and also on a 129Sv genetic background) likely results from heart, liver, and placental defects. Please note that homozygous mutants on a mixed/outbred genetic background (129/Sv X Black Swiss) are viable and fertile. These mutant mice may be useful in studying the role of Crkl tyrosine-phosphorylation in Bcr/Abl (Philadelphia chromosome) chronic myelogenous leukemia (CML), acute lymphoblastic leukemia (ALL), Digeorge Syndrome (DGS) and Velocardiofacial Syndrome.
011112 B6.129-Flt3tm1Dgg/J
Repository- Live
These mice carry the human W51 mutation, ITD, internal tandem duplication of amino acids 596 to 602, in the endogenous mouse Flt3 locus, which confers constitutive FLT3 signaling. Mice that are homozygous for the targeted mutation are viable and fertile. The Donating Investigator reports that BALB/c mice carrying this allele are not as viable as mutants on the C57BL/6 background. Although FLT protein levels are comparable to wildtype, increased phospho-Flt3 (p-FLT3) and phospho-Stat5 (pSTAT5) levels are detected by flow cytometric analysis of homozygous bone marrow and splenic cells. Homozygotes exhibit leukocytosis, monocytosis and progressive splenomegaly. Mature myeloid and monocytic populations in homozygotes are increased, with reduced B and T cell populations. B cell development is arrested at the pre-B stage. Heterozygotes have decreased liver size, hemoglobin levels, platelet counts and exhibit a milder maturing myeloid hyperplasia phenotype when compared to hom .....

008463 B6.129-Gt(ROSA)26Sortm1(cre/ERT2)Tyj/J
Repository- Live
A conditional Cre-ERT2 (Cre recombinase - estrogen receptor T2) cassette was introduced to the gene. The ERT2 moiety retains the Cre recombinase in the cytoplasm until tamoxifen administration releases this inhibition, thus permitting the recombination of genomic loxP sites. Efficient tamoxifen-induced Cre-mediated recombination throughout the body has been demonstrated through crosses with a Cre-responsive beta galactosidase reporter strain. This strain enables temporal control of floxed gene expression in vivo and is reportedly more sensitive to tamoxifen than Stock No. 004847. Homozygotes are viable and fertile.
005867 B6.129-Ido1tm1Alm/J
Repository- Live
Homozygous mice are viable and fertile with normal immune system development and function. They exhibit no spontaneous autoimmune disorders. No gene product (mRNA or protein) from the targeted gene is detected in the epididymis. At embryonic day 10.5, endogenous protein is absent from all cells at the maternal-fetal interface when both parents are homozygous for the targeted gene. Allogeneic and syngeneic pregnancy outcomes are unaffected by this mutation. In contrast to wild-type, anti-proliferative treatments (CTLA4-Ig, IFNalpha, or CpG-ODN) do not suppress T cell expansion both in vivo and in vitro. In addition, homozygous dendritic cells isolated from lymph nodes draining (induced) tumor sites have no suppressor activity. These mice may be useful in studies of pregnancy and reproductive immunology (tryptophan degradation, T cell activation, clonal expansion) as well as autoimmune disease, tissue transplantation, fostering, acquired tolerance/T cell anergy, and immunos .....

010818 B6.129-Ifnb1tm1Lky/J
Repository- Live
The Ifnb1 gene was targeted to introduce an internal ribosomal entry site (IRES) and enhanced yellow fluorescent protein (EYFP) immediately behind the stop codon of the gene. All regulatory elements, including the polyadenylation signal, are left intact and are derived from the endogenous gene. When activated, the targeted gene co-translates EYFP both in vitro and in vivo, leaving cells that have made type 1 interferon-beta readily detectable by flow cytometry or immunohistochemistry. Expression of EYFP faithfully mimics the expression of the targeted gene.
006412 B6.129-Il12btm1Lky/J
Repository- Live
Mice homozygous for this bicistronic "yet40" allele are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. The IRES-EYFP is inserted downstream of the endogenous stop codon, allowing for normal expression of the endogenous gene and simultaneous EYFP reporter expression. ELISA assays confirm that p40 protein is expressed at similar levels in homozygous mutant and wildtype mice. The EYFP reporter marks dendritic cell (DC) and macrophage lineage cells that produce p40 following stimulation with toll-like receptor (TLR) ligands both in vivo and in vitro. These mice may be useful for labeling activated IL12/23 p40 expressing cells in studies of immunology and immunity, TLR signal cascades, cancer immunity, and vaccine development.
008451 B6.129P(Cg)-Ptprca Cx3cr1tm1Litt/LittJ
Repository- Live
Mice that are homozygous for the CX3CR1-GFP targeted mutation are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. RT-PCR analysis of lymphoid tissue from homozygotes detects mutant gene product (mRNA) and no wild type gene product (mRNA). Flow cytometric analysis of peripheral blood cells identified a subset of green fluorescent cells not observed in wild type mice. Enhanced Green Fluorescent Protein (EGFP), but not the endogenous gene, is expressed in monocytes, dendritic cells, NK cells, and brain microglia, mimicking endogenous gene expression. The same subset of peripheral blood cells isolated from heterozygote mice express detectable levels of EGFP. Immunohistochemical analysis of spleen and peripheral nerve tissue from homozygotes does not detect EGFP. These mice also express the CD45.1 (Ly5.1 or Ptprca) allele, which is atypical for the C57BL/6 congenic background, and this marker may be used to track donor cell popul .....

Repository- Live
Mice heterozygous for the ROSA:LNL:tTA conditional mutation of the Gt(ROSA)26Sor locus are viable and fertile, with a loxP-flanked STOP cassette preventing transcription of a downstream optimized/modified tetracycline-controlled transactivator protein ("mtTA"). Applying both Cre-lox and Tet-Off technologies, these ROSA:LNL:tTA mutant mice may be useful to generate compound mutant mice in which expression of a tetracycline-responsive promoter element (TRE; also called tet-operator or tetO)-driven gene of interest can be both directed to the cell types defined by the chosen Cre recombinase expression, as well as turned off by the addition of tetracycline (or its analog doxycycline (dox)).
009088 B6.129P2(SJL)-Myd88tm1.1Defr/J
Repository- Live
Homozygous mice are viable and fertile. The Myd88-deficient allele encodes a deletion of exon 3 of the myeloid differentiation primary response gene 88 locus. Myd88-deficiency is associated with a number of immune system abnormalities, as well as hematopoietic system, molecular signaling, and apoptotic abnormalities.
008875 B6.129P2-Lgr5tm1(cre/ERT2)Cle/J
Repository- Live
While homozygous mice are not viable, heterozygous Lgr5-EGFP-IRES-CreERT2 mice are viable and fertile; harboring a Lgr5-EGFP-IRES-creERT2 "knock-in" allele that both abolishes Lgr5 (Gpr49) gene function and expresses EGFP and CreERT2 fusion protein from the Lgr5 promoter/enhancer elements. EGFP fluorescence is observed in crypt base columnar cells in small intestine (aka stem cells of the small intestine) and colon. Cre-ERT2 fusion gene activity is inducible; observed in the same cells only following tamoxifen administration. EGFP or inducible CreERT2 expression may also be observed in other Lgr5-expressing cell types (including pre-malignant mouse adenomas, colon cancer cells, epithelial stem cells of the stomach gland, basal epithelial layer stem cells of the mammary glands, and hair follicle stem cells).

The donating investigator reports variegated expression of the Lgr5-EGFP-IRES-CreERT2 transgene in the small intestine and colon (something which may h .....

Repository- Live
This strain expresses Cre recombinase from the endogenous Lyzs locus. When crossed with a strain containing loxP site flanked sequence of interest, Cre-mediated recombination results in deletion of the targeted gene in the myeloid cell lineage, including monocytes, mature macrophages, and granulocytes. Mice that are homozygous for the targeted mutation are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. This strain represents an effective tool for generating myeloid cell-specific targeted mutants.
008462 B6.129P2-Trp53tm1Brn/J

Exons 2-10 are flanked by loxP sites in this conditional targeted mutation. Mice homozygous for the floxed allele do not show any increase in disease incidence for at least a year. When bred to mice with a cre recombinase gene under the control of a promoter of interest, expression is deleted in the tissue of interest.

For example, when crossed to a strain expressing Cre recombinase in the nervous system (see Stock No. 003771), this mutant mouse strain may be useful in studies of medulloblastoma formation.

When crossed to a strain expressing Cre recombinase in the central nervous system (see Stock No. 004600), this mutant mouse strain may be useful in studies of astrocytoma formation.

The donating investigator reports that homozygous mice are viable and fertile but few pups are produced, and they need a gnotobiotic facility to thrive. Homozygous mice have several abnormalities, including neurological defects, impaired wound healing, impaired angiogenesis, and altered growth of induced/implanted tumors. Homozygotes may also exhibit splenomegaly, lymphadenopathy, and increased susceptibility to various pathogens due to impaired neutrophil recruitment and decreased pathogen clearance during innate immune responses. These mutant mice may be useful in studies of inflammation and immunology and cancer biology.

In an attempt to offer alleles on well-characterized or multiple genetic backgrounds, alleles are frequently moved to a genetic background different from that on which an allele was first characterized. It should be noted that the phenotype could vary from that originally described. We will modify the strain description if necessary as published results becom .....

Homozygous (12/15-LO-deficient) mutant mice are viable and fertile. 12/15-LO-deficient mice develop a myeloproliferative disorder (MPD) (similar to human chronic myelogenous leukemia (CML)) that progresses to transplantable leukemia. Chronic MPD stage homozygotes exhibit increased activation of the phosphatidylinositol 3–kinase (PI3-K) pathway, hyperphosphorylation/decreased nuclear accumulation of the transcription factor interferon consensus sequence binding protein (ICSBP), and increased expression of the oncoprotein Bcl-2; all of which are reversible upon treatment with a PI3-K inhibitor. The evolution of MPD to leukemia is associated with additional regulation of ICSBP at the RNA level. Peritoneal macrophages have altered arachidonic acid metabolism as well as a diminished ability to oxidize low density lipoprotein (LDL) following stimulation. These mutant mice may be useful in studying myeloproliferative disorders, chronic myelogenous leukemia, and other cancers.

Mice homozygous for this targeted mutation are viable and fertile, with an approximate 20% decrease in embryo/neonate viability and a mild and variable lordotic curvature of the spine apparent from birth. Homozygous mice have an abnormal, but no full length transcript in multiple tissues. Western analysis confirmed the absence of the protein in platelets. Homozygotes exhibit an increase in the number of circulating white blood cells. During the first four to ten weeks of life, homozygotes exhibit patches of acute and organizing pneumonia. At later time points, there is considerable hyperplasia of the various epithelial cell lineages. Mutant mice also have an increased number of retinal endothelial cells and inappropriate remodeling and maturation of retinal vasculature following injury. On the FVB/N background, spontaneous tumor growth and vasculature are significantly increased compared to wildtype. Mutant mice may be useful in studies of inflammatory responses in the lungs, eye, and .....

Mice homozygous for this BLTR (BLT1)-deficient allele are viable and fertile. Northern blot analysis of neutrophils, macrophages, lymph nodes, lungs, and spleens isolated from homozygous mice show absence of the normal transcript and presence of the expected larger transcript (due to the insertion of the neomycin resistance cassette in exon 2 of the targeted gene), albeit at lower levels than the wild type transcript. Homozygous disruption of this allele confers impaired leukocyte function (chemotaxis, recruitment, firm adhesion). For example, homozygotes exhibit substantially diminished recruitment of eosinophils in a model of peritonitis, effector T cells in a model of allergic pulmonary inflammation, and neutrophils in a model of rheumatoid arthritis. As the G protein-coupled receptor BLTR/BLT1 is expressed on myeloid leukocytes (including neutrophils, macrophages, eosinophils, T cell lymphomas, and effector T cells (TH1 CD4+ cells, TH2 CD4+ cells, and effecto .....

Mice homozygous for both mannose-binding lectin (MBL)-A and MBL-C targeted mutations (termed MBL-null) are viable, fertile, and normal in size with no obvious developmental defects. Histological examination of multiple organs from 6-10 week old mice shows no abnormalities. MBL-null mice have no endogenous gene expression in liver (the principal site of MBL synthesis) and no protein detectable in serum. While the classical complement pathway is unaffected in MBL-null mice, the lectin-dependent complement pathway is non-functional. MBL-null mice have increased mortality following intravenous injection of S. aureus associated with abnormal serum levels of TNFalpha and IL-6 (decreased at 2h, elevated at 24h post injection). Cyclophosphamide-induced febrile neutropenic MBL-null mice inoculated with S. aureus have greatly increased susceptibility to abscess formation in kidney, liver, and lung (but not spleen).

Mice homozygous for this E-selectin mutant allele (E-/-) are viable and fertile with normal circulating leukocyte and platelet profiles. While several transcripts are generated from the mutant locus (due to transcription from the endogenous promoter and/or bidirectional transcription initiated from the pgk promoter in the neo-resistance cassette), these frame-shifted transcripts are non-functional with several predicted stop codons. In contrast to wildtype mice, no protein product is detected in several tissues isolated from LPS-injected homozygous mice. Homozygous mice exhibit abnormal responses to inflammatory stimuli. E-selectin deficiency results in endostatin unresponsiveness (as shown in corneal angiogenesis (mixed B6;129 genetic background) and aortic explant (C57BL/6 congenic background) experiments).

When crossed with a tissue-specific cre strain, excision of a floxed stop cassette enables expression of the cDNA driven by the endogenous mouse Gt(ROSA)26Sor promoter. There is no expression until the mice are exposed to Cre recombinase. This strain may be useful in studies of von Hippel-Lindau disease mechanisms.

Homozygous (CD1-deficient) mice are viable and fertile, with no protein expression from the targeted locus observed on antigen presenting cells (APC) by FACS analysis. Natural killer T (NKT) cells are restricted by MHC class I-like CD1 molecules expressed on APC, and because the CD1 molecule is also required for the development of NKT cells, these CD1-deficient mice selectively lack NKT cells. Because activated NKT cells normally produce interleukin-4 (IL-4), interferon-gamma, granulocyte-macrophage colony-stimulating factor, IL-2 and TNF-alpha, CD1-deficient mice may exhibit abnormal immune responses dependent upon such cytokines/chemokines. These CD1-deficient mice may be useful in studying NKT cell immunology; including Th1- and Th2-responses, antiviral and antitumor responses, asthma, various inflammatory responses, autoimmunity and peripheral tolerance.

These Ift20flox mice harbor loxP sites flanking exons 2-3 (encoding the first 71 codons including the start codon) of the intraflagellar transport 20 homolog (Chlamydomonas) locus. The primary cilium is a microtubule-based antenna-like structure that emanates from the surface of virtually all cells in the mammalian body. The primary cilium functions as a sensory organelle (mechano-, chemo-, photo-receptor) that receives signals from other cells/the environment, and transmits these signals to the nucleus to elicit a cellular response. Most types of eukaryotic cilia and flagella are assembled and maintained by the process of intraflagellar transport (IFT). During IFT, large protein complexes (IFT particles) are transported along the ciliary microtubules under the ciliary membrane. IFT particle proteins organize into at least three distinct complexes called complex A, complex B and the Golgi IFT complex. The unique role of Ift20 in both complex B as well as the Golgi IFT .....

These mutant mice express a MHC class II-restricted TCR recognizing the endogenous melanocyte differentiation antigen minimal TRP-1 (tyrosinase-related protein 1) epitope corresponding to amino acids 113 to 127. The transgene is located on the Y chromosome in founder line 9. On a RAG-deficient background, these mice are also homozygous for the Tyrp1B-w mutation and do not produce endogenous tyrosinase-related protein 1.

Mice homozygous for the Rag1 targeted mutation and heterozygous for the Akita spontaneous display the diabetes phenotype in the absence of B and T cells and unlike single Akita mice, double mutants do not reject allografts. Mice heterozygous for only the Akita spontaneous mutation are viable and fertile. (Homozygotes typically die by 12 weeks of age from extreme hyperglycemia.) Symptoms in heterozygous mutant mice include hyperglycemia, hypoinsulinemia, polydipsia, and polyuria, beginning at approximately 3-4 weeks of age. The diabetic phenotype is more severe and progressive in heterozygous males than in females. Obesity and insulitis do not accompany diabetes.

This double mutant strain is ideally suited for use in allogeneic or xenogeneic islet or stem cell transplantation protocols because the mice are severely immunocompromised and spontaneously develop diabetes at a young age.

Approximately 37% of tumor-bearing mice develop metastatic disease to the lung. High expression of neu is detected in tumor tissue while very low levels are found in lung and ovary.

Female mice carrying only the neuOT-I/OT-II mutation develop focal mammary tumors at approximately 18 months of age.

This strain may be useful in studies of cancer immunotherapy.

Mice heterozygous for both targeted mutations (R26-rtTA and Cola1a::tetO-Oct4) are viable and fertile. These "Oct-4/rtTA" mice express rtTA-M2, an optimized form of reverse tetracycline-controlled transactivator (rtTA) protein, in multiple tissues. In the absence of the tetracycline analog doxycycline (dox), Oct4 (Pou5f1) expression from the Col1a1 locus is not detected. Following dox administration, high Oct4 expression is induced in liver, bone marrow, stomach, intestine, and skin, with lower levels in the heart, lungs, kidney, spleen, and thymus; no expression was detected in the brain and testes. Dox-inducd activation of Oct4 results in dysplasia in epithelial tissues. These mutant mice may be useful for studies of tumorigenesis and pluripotent cells.

Mice homozygous for this targeted allele (SirT1co/co) are viable and fertile. A loxP-flanked neomycin cassette just upstream of exon 4 and a third loxP site downstream of exon 4 were inserted to create this targeted mutant Sirt1 allele. The floxed mutation does not affect SIRT1 protein expression in MEFs or mammary gland tissue in homozygotes. When bred to mice that express Cre recombinase, the resulting offspring have exon 4 (encoding an evolutionarily conserved Sir2 motif) deleted in cre-expressing tissue(s); (the donating investigator reports only one recombination event: complete removal of the neomycin cassette and exon 4, leaving a single loxp). These SirT1co/co mice may be useful in generating conditional mutants for studying transcriptional regulation and the role of estrogen, insulin growth factor-1 (IGF-1), and transcription factors (including NF-kappaB) in mammary gland development, mammary cancer, apoptosis, and metabolic di .....

A targeting vector was designed to replace the C-terminus DNA-binding domain of transcription factor 4 (Tcf4 or E2-2) gene with a neomycin (neo) selection cassette. Homozygotes are born at a low frequency and die within the first week of life. E2-2 is a widely expressed E2A-related helix-loop-helix (HLH) protein required for the generation of normal numbers of pro-B cells in mouse embryos. While homozygous E2-2 mutant embryos are capable of making B cells, they produce only half as many as wildtype. When crossed to mice containing a (Atoh1)-lacZ transgene, β-galactosidase staining is evident in anterior extramural migratory stream (AES) cells which accumulate in the region lateral to the pontine nucleus. The resulting mice exhibit a reduction in size of the pontine nucleus and a lack of migration of neuronal precursors to the region of the pontine nucleus. Mice heterozygous for the mutation are viable, fertile, and normal in size. This strain may be .....

These TRF1F mice harbor loxP sites flanking exon 1 (encoding the translation start site) of the telomeric repeat binding factor 1 locus. Telomeres serve a dual role in protecting the chromosome ends from degradation/repair activities and in intracellular signaling for regulating cell proliferation. Mammalian telomeres are formed by tandem TTAGGG sequence repeats bound by a specialized complex of six telomere-associated proteins called the shelterin complex. As TRF1 is one of the components of shelterin, these TRF1F mutant mice may be useful in generating conditional mutations for studying the shelterin complex of telomeres, telomere maintenance, chromosomal stability, cancer, and aging.

Mice homozygous for the Col1a1-tetO-OKSM targeted mutation are viable and fertile, although the donating investigator reports that homozygous mice do not breed as well as expected. Expression of the OKSM cassette (four mouse reprogramming genes Oct4 [Pou5f1], Klf4, Sox2, and c-Myc [Myc]) is controlled by the tet-responsive element (tetO; also called tetracycline operator, tet-operator, or tetracycline-responsive element [TRE]) with CMV minimal enhancer-less promoter. When bred with another mouse expressing reverse tetracycline-controlled transactivator protein (rtTA) or tetracycline-controlled transactivator protein (tTA), expression of the OKSM cassette can be regulated with the tetracycline analog doxycycline (dox) in the resulting double mutant offspring. Somatic expression of the OKSM reprogramming factors allows multiple somatic cell types to be directly reprogrammed to generate induced pluripotent stem cells (iPSCs). Because the reprogram .....

Mice homozygous for the Rag1tm1Mom mutation produce no mature T cells or B cells. Their phenotype can be described as a "non-leaky" severe combined immune deficiency (Prkdcscid/Prkdcscid) (Prkdcscid mice produce some B cells and IgM). They have no CD3+ or T cell receptor (TCR) alpha-beta positive cells. The thymus of the mutant mice contains 15 to 130 times fewer cells than heterozygous or wildtype siblings. The thymocytes are CD8-CD4- and most are IL2 receptor positive. Neither the spleen nor bone marrow contain any IgM or IgD staining cells, indicating an absence of mature B cells. These and other data suggest that B cell and T cell development has been arrested at an early stage. Macroscopically, the mutants are indistinguishable from heterozygotes or normal wildtype siblings.

The donating investigator claims homozygous mice are viable and fertile. These MMTV-rtTA mice have expression of the reverse tetracycline-controlled transactivator (rtTA) protein directed primarily to the breast epithelia of the mammary ductal system by the mouse mammary tumor virus (MMTV) promoter. The donating investigator also reports some rtTA expression in salivary glands (particularly in the males) as well as prostate glands. When mated to a mutant strain carrying a gene of interest under the regulatory control of a tetracycline-responsive promoter element (TRE, TetRE or tetO), expression of the target gene may be induced with administration of the tetracycline analog doxycycline (dox) in the double mutant offspring. These MMTV-rtTA mice are a Tet-On tool that allows conditional, dox-inducible expression of genes primarily in mammary gland epithelial cells and may be useful in studying the endocrine function of mammary tissues and/or breast cancer (for example).

Homozygous C57BL/6-plt mice are viable and fertile, harboring the spontaneous plt (or "paucity of lymph node T cells") deletion of both the Ccl19 and Ccl21a loci on chromosome 4. Lack of expression of these two CCR7 ligands in the secondary lymphoid organs results in abnormal leukocyte migration and impaired immune response. Specifically, homozygous mice have disrupted trafficking/homing of T cells and dendritic cells to lymphoid tissues. No reported abnormalities in B cell distribution/cellularity are reported for homozygous mice. Transient migration of antigen-stimulated B cells in lymphoid organs (which facilitates B cell/helper T cell interactions) is also impaired in homozygous mice. Homozygous mice exhibit mature single-positive thymocyte arrest in the thymic cortex that results in defective formation of the medullary region of the thymus. Thymic export of T cells in these mice is compromised during the neonatal period but not in adulthood. While C .....

Hybridomas are produced by fusing mouse meloma cells that are deficient in adenosine phosphoribosyltransferase (APRT) with spleen cells from mice immunized with specific antigens. A selection system using AAT (adenosine, aminopterin, and thymidine) medium eliminates all but the fusion cells that are APRT+ . Successful hybridomas must also retain the Igh heavy chain locus on chromosome 12 and one of the Igh light chain loci. The Robertsonian chromosome Rb(8.12)5Bnr can be used to produce hybridomas at a high frequency. Selecting for the Aprt locus on chromosome 8 also selects for the Igh locus on chromosome 12 because the two loci are "genetically linked" by the Robertsonian fusion chromosome. This chromosomal aberration congenic was created by backcrossing the Robertsonian chromosome Rb(8.12)5Bnr on the BALB/cByJ genetic background by Dr. Muriel Davisson at The Jackson Laboratory.

When these VE-Cadherin-tTA mice are bred with mice carrying a gene of interest under the regulatory control of a tetracycline-responsive promoter element (TRE, TetRE or tetO), expression of that gene in blood vessel endothelial cells may be conditionally inactivated with administration of the tetracycline in the double mutant offspring. Tetracycline was used by the Donating Investigator in the original publication Proc Natl Acad Sci 2005;102:128-33. When crossed with a strain carrying a tetracycline-responsive promoter driven lacZ transgene, beta-galactosidase is expression is observed in VEGFR-2, CD31 expressing cells in the blood vessels of bi-transgenic day 13.5 aged embryos. Mice homozygous for the transgenic insert are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities.

Repository- Live
Mice heterozygous for this "ODD-luc" knock-in are viable and fertile with no gross phenotypic or behavioral abnormalities. These mice have the C-terminal portion of the hypoxia-inducible factor 1 alpha (HIF1A) oxygen-dependent degradation domain (ODD) fused to the firefly luciferase (luc) gene. This region of the ODD also contains a proline residue (amino acid 564) that, when hydroxylated, will serve as a binding site for von Hippel-Lindau tumor suppressor protein (pVHL). Under normal oxygen concentrations, prolyl hydroxylation by egg-laying-defective nine (EGLN) proteins leads to pVHL-dependent polyubiquitylation and proteasomal degradation (thus, little or no luciferase fluorescence). Under hypoxia, proline hydroxylation is impaired and ubiquitination is attenuated, resulting in stabilization of the fusion protein and high levels of luciferase fluorescence in the hypoxic tissue(s). These "ODD-Luc" bioluminescent reporter mice may be useful in researching transcriptional .....

Mice homozygous for the Rag1tm1Mom mutation produce no mature T cells or B cells. Their phenotype can be described as a "non-leaky" severe combined immune deficiency. (Prkdcscid/Prkdcscid) mice produce some B cells and IgM. NOD.129S7(B6)-Rag1tm1Mom/J mice have no CD3+ or T cell receptor (TCR) alpha-beta positive cells. The thymus of the mutant mice is severely involuted. The thymocytes are CD8-CD4- and most are IL2 receptor positive. Neither the spleen nor bone marrow contain any IgM or IgD staining cells, indicating an absence of mature B cells. These and other data suggest that both B cell and T cell development have been arrested at an early stage. Macroscopically, the mutants are indistinguishable from heterozygotes or normal wildtype siblings. Notable differences between this strain and the NOD.CB17-Prkdcscid/J strain (Stock No. 001303) include a longer life s .....

Mice that are homozygous for the targeted mutation are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. NOD.CB17-Prkdcscid mice with the DR1 transgene survive to 14 months as compared to 8.5 months without the transgene. Physiological parameters in this strain are similar to NOD.CB17-Prkdcscid mice. Engraftment of human hematopoietic cells occurs regardless of DR1 genotype and is enhanced by intrahepatic engraftment using neonatal mice. Following injection, 15-20% human CD45+ cells are detected in peripheral blood. Short-term engrafted cord blood mononuclear cells can mount an immune response to tumor-associated antigen.

Mice that are homozygous/hemizygous for these alleles are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. These mutant mice combine the following characteristics: NK cell deficiency (NOD/ShiLtJ background), T and B cell deficiency (Prkdcscid), reduced numbers of lymphocytes and myeloid dendritic cells (Il2rgtm1Wjl) and biochemically defective stromal cells (Hprtbm-3). These mice can be used for transplantation of human primary cancers. During tumor growth, Hprt-defective murine fibroblast and stromal cells replace human stromal cells. In culture, the addition of HAT selection media eliminates murine fibroblasts and other stromal cells and facilitates the isolation of human cancer cells. These mice may be used to generate patient-specific low passage cell lines from primary cancers for use in chemosensitivity profiling and other applications.

Mice homozygous for both the hHGFki and Prkdcscid alleles, also called immunocompromised hHGFki mice, are viable and fertile.

The hHGFki allele is a "humanized" knock-in mutation that replaces the mouse hepatocyte growth factor (HGF) coding region downstream of the signal sequence with the human HGF cDNA sequence. As a result, the endogenous mouse promoter drives expression of human HGF. While the human HGF activates both the human and murine form of its tyrosine kinase receptor (met proto-oncogene (MET; c-Met)), the murine HGF is unable to activate human MET. Mice homozygous for hHGFki express only the human form of HGF. In homozygous hHGFki mice, HGF expression from the knock-in allele is observed in developing embryo, as well as adult liver, kidney and lung. hHGFki homozygous mice exhibit an increase in serum HGF after clotting.

The Mll-AF9 knock-in allele encodes a MLL-AF9 fusion protein that mimics the t(9;11)(p22;q23) translocation identified in acute myeloid leukemia (AML) patients. While homozygous mice are not viable, heterozygotes are viable and fertile but females are poor mothers and may not survive pregnancy. Expression of the MLL-AF9 fusion protein results in development of leukemia beginning around six months of age; almost all of which are AMLs. Detectable proliferation of myeloid cells is observed in bone marrow by as little as six days after birth, and this early accumulation of myeloid precursors likely confers a greater chance of acquiring secondary mutations that cooperate in the appearance of overt cancer.

When bred to mice that express Cre recombinase, the resulting offspring will have exon 7 deleted in the cre-expressing tissue(s); splicing of upstream exons (exon 6, 1b, or 1c) directly into the downstream exon 8 results in a frameshift mutation that introduces an immediate stop codon.

These mice contain a reverse tetracycline-controlled transactivator (rtTA) protein in the 5' untranslated region of the whey acidic protein (Wap) gene. Homozygous mice are viable, fertile, and normal in size. WAP, expressed late during pregnancy and during lactation in the mammary gland, is the principal whey protein found in rodent milk. When mated to a mutant strain carrying a gene of interest under the regulatory control of a tetracycline-responsive promoter element (TetO), the Wap-rtTA allele mediates expression of TetO-responder genes in the developing mammary gland upon administration of doxycycline (dox). Since expression of the endogenous WAP locus is elevated during pregnancy and lactation, the expression of TetO responder genes is particularly high during these stages of mammary gland development. The Wap-rtTA mice are useful to express exogenous proteins including teto-regulated oncogenes in the mammary epithelium.

Homozygous CAG-stop-tTA2 transgenic mice are viable and fertile. CAG-stop-tTA2 transgenic mice harbor the ii-CAG-stop-tTA2-IRES-tau-lacZ-ii transgene; designed with a loxP-flanked transcriptional STOP cassette preventing transcription of the downstream modified tetracycline-regulated transactivator (tTA2). The ii-CAG-stop-tTA2-IRES-tau-lacZ-ii transgene is flanked by two copies of the chicken β-globin HS4 insulator on each side to preserve expression fidelity (see additional information below). When bred to mice that express a tamoxifen-inducible Cre recombinase (CreERT2), administration of tamoxifen to the double mutant offspring allows the CreERT2 fusion protein to enter the nucleus of the cre-expressing cells; this deletes the STOP cassette and results in expression of tTA2. The donating investigator reports that tau-lacZ fusion protein expression in the tamoxifen-treated double mutant offspring is faint. Of note, the donating investigator h .....

Repository- Live
This strain was generated by breeding Stock No. 008168 and Stock No. 008250 together at The Jackson Laboratory. The resulting double transgenic colony was established as Stock No. 008755.

The Ins2-rtTA (or RIP7-rtTA) transgene expresses the reverse tetracycline-controlled transactivator (rtTA) protein under the control of the rat insulin 2 (Ins2) promoter. The tet-DTA (or tetO-DTA) (transgene expresses diphtheria toxin A (DTA) under the control of a tetracycline operator (tetO; also called tetracycline-responsive element (TRE) or tet-operator) and a cytomegalovirus minimal promoter. Mice harboring both of these transgenes has doxycycline-inducible expression of DTA in pancreatic beta cells; i.e. addition of the tetracycline analogue doxycycline (dox) results in ablation of pancreatic beta cells.

Hemizygous transgenic mice are viable, fertile, normal in size, and do not display any gross physical or behavioral abnormalities. These transgenic mice harbor co-injected transgenic constructs. The reverse tetracycline-controlled transactivator (rtTA) protein is expressed under the direction of the endothelial-specific receptor tyrosine kinase enhancer/promoter (Tek). The second transgenic construct expresses a nuclear-localizing beta-galactosidase gene (lacZ) under the control of a tetracycline-responsive element (TRE). In the presence of tetracycline or a tetracycline analog (such as doxycycline), selective expression of lacZ is observed in the nuclei of vascular endothelium in a wide variety of tissues (aorta, heart, brain, lung, kidney, liver, spleen, uterus, prostate, stomach, skeletal muscle, large and small intestine). Expression is observed as early as embryonic day 9.5. In the absence of tetracycline, some lacZ expression occurs in the smaller branches of .....

Repository- Live
Mice harboring the Thy1-GFP transgene are viable and fertile with enhanced green fluorescent protein (EGFP) expression under the control of a modified Thy1 promoter region (containing the sequences required for neuronal expression but lacking the sequences required for expression in non-neural cells). Homozygous or hemizygous Thy1-GFPM mice (derived from founder line M) express EGFP in sparse subsets of neurons within specific populations; providing a bright, vital Golgi-like stain. Less than 10% of all motor axons, retinal ganglion cells, lumbar dorsal root ganglion, and cortex express EGFP. These Thy1-GFPM transgenic mice may be useful in neurobiological studies for fluorescent labeling of neural tissues, especially for mossy fibers in the cerebellum and intense, yet sparse, labeling of a variety of neuronal subsets.

Hemizygous TRE-Bi-SG-T line 1.1 transgenic mice are viable and fertile, with no reported phenotypic abnormalities. The TRE-Bi-SG-T transgene has Myc-tagged tdTomato and full-length mouse synaptophysin/mut4EGFP fusion protein (Syp-GFP) expression under the control of the bi-directional tet-responsive promoter (tetO or TRE). When bred with another mouse expressing tetracycline-controlled transactivator protein (tTA) or reverse tetracycline-controlled transactivator protein (rtTA), tdTomato and Syp-GFP fusion protein expression can be regulated with the tetracycline analog doxycycline (dox) in the resulting double mutant offspring. In tTA(-dox) or rtTA(+dox)-expressing cells, tdTomato expression is directed to the entire cell, while GFP expression is directed to the synapse/synaptic vesicle.

Research Strain
Tg(UBC-GFP)30Scha generates green fluorescent protein (GFP) expression in all cells of the body with cell lineage-specific variation in expression level. Hematopoetic cells have high expression levels compared with other cells and T cells have a 2-fold higher GFP expression level than that in CD19+B220+ B cells. The Rag1tm1Mom targeted disruption, which blocks the intragenic recombination essential for T and B cell antigen receptor formation, leaves homozygous mice immunocompromised due to the inability to form functional, mature T and B cells. This strain, which combines this targeted mutation with this transgene, is a universal host that does not reject engraftment regardless of histoincompatibility and permits detection of host-derived embryos or tissues by detection of GFP, as long as the donor tissue is not also engineered to express GFP. Animals from this strain can also be used as sentinel mice in specific pathogen free environments. .....

Research Strain
Mice homozygous for the severe combined immune deficiency spontaneous mutation (Prkdcscid, commonly referred to as scid) are characterized by an absence of functional T cells and B cells, lymphopenia, hypogammaglobulinemia, and a normal hematopoietic microenvironment. Normal antigen-presenting cell, myeloid and NK cell functions are strain dependent. scid mice carry a DNA repair defect and a defect in the rearrangement of genes that code for antigen-specific receptors on lymphocytes. Most homozygotes have no detectable IgM, IgG1, IgG2a, IgG2b, IgG3, or IgA. Thymus, lymph nodes, and splenic follicles are virtually devoid of lymphocytes. scid mice accept allogeneic and xenogeneic grafts making them an ideal model for cell transfer experiments. Some scid mice will spontaneously develop partial immune reactivity. scid mice that have serum Ig levels greater than 1 ug/ml are considered "leaky." scid leakiness is highly strain depen .....

Mice homozygous for the targeted mutation are viable. Although fertile, they produce litters at reduced efficacy compared to wild type or heterozygous mice. Null mutants are approximately 20%-30% smaller than heterozygous or wildtype litter mates, with males exhibiting a more pronounced size reduction. Reporter lacZ expression is observed in many developing embryonic tissues with highest levels in mesenchymal derivatives. Expression in adult mutant mice is observed in the colon, with highest levels in the muscularis propria and submucosa with lower levels in the epithelium. At approximately 4-6 months of age, they develop gastric tumors. The donating investigator originally described spontaneous, deeply invasive colorectal adenocarcinomas that penetrate through all layers of the intestinal wall and metastasize to lymph nodes. Colorectal adenocarcinomas are not a component of the phenotype observed in this strain at The Jackson Laboratory. However, the gastric epithelium was fo .....

Mice homozygous for this E-selectin mutant allele (E-/-) are viable and fertile with normal circulating leukocyte and platelet profiles. While several transcripts are generated from the mutant locus (due to transcription from the endogenous promoter and/or bidirectional transcription initiated from the pgk promoter in the neo-resistance cassette), these frame-shifted transcripts are non-functional with several predicted stop codons. In contrast to wildtype mice, no protein product is detected in several tissues isolated from LPS-injected homozygous mice. Homozygous mice exhibit abnormal responses to inflammatory stimuli. E-selectin deficiency results in endostatin unresponsiveness (as shown in corneal angiogenesis (mixed B6;129 genetic background) and aortic explant (C57BL/6 congenic background) experiments).

Mice homozygous for this targeted mutation (called "Snoex1" in the primary reference) are viable and fertile with no reported gross morphological defects. Although the deletion of exon 1 leads to complete absence of the mature full-length protein in immunoblots of brain and embryonic tissues, a truncated 3'-end RNA species is derived from downstream coding sequence. Homozygotes exhibit T cell proliferation/activation defects, which can be rescued by treatment with anti-TGF-beta antibodies or exogenous interleukin-2. Homozygous deletion also results in increased sensitivity to TGF-beta and altered growth properties of cultured mouse embryo fibroblasts (MEFs). These mutant mice may be useful in studies of T cell activation, T cell receptor stimulation and TGF-beta signaling.

Heterozygous mice are viable, fertile, devoid of hemorrhagic lesions, and exhibit mild hematopoietic impairment. Mice that are homozygous for the targeted mutation have an embryonic lethal phenotype; animals are alive at embryonic day 11.5, but start dying at embryonic day 12.5. Embryos exhibit extensive hemorrhagic lesions in the central nervous system including the intraventricular regions and metencephalon as well as segmental bleeds at the VII-VIII cranial nerve complex, cervical, thoracic, and caudal regions. At embryonic day 10.5, symmetrical and bilateral necrosis preceding hemorrhage is observed in homozygotes. Homozygous disruption of the endogenous gene completely blocks definitive erythropoiesis, myelopoiesis, and lymphopoiesis. This mutant may be useful in leukemia studies as disruption of the human homolog of this gene is associated with many different leukemias.

Cryopreserved - Ready for recovery
Mice that are homozygous for the targeted mutation are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. In the absence of Cre, there is low level expression of Luciferase-SIY H2b antigen expression. After Cre activity, the recombined locus has high expression of Luciferase-SIY fusion protein. This mutant mouse strain may be useful in studies of immune response to a self-antigen or over-expressed tumor-associated antigen when used in combination with tumor-prone models. This mouse is also useful as a reporter for Cre activity.
005897 B6.129S4-Ppardtm1Rev/J
Cryopreserved - Ready for recovery
These mice possess loxP sites on either side of exon 4 of the targeted gene. Mice that are homozygous for this allele are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. When bred to mice with a cre recombinase gene under the control of a promoter of interest, exon 4 of the targeted gene is deleted in the tissue of interest, leading to premature termination of the translation product upstream of the DNA binding domain. This strain may be useful in generating tissue-specific mutants of the floxed allele for use in studies including embryo development, adipocyte physiology, fat metabolism and storage, inflammation, and cancer.
005901 B6.129S4-Ppardtm2Rev/J
Cryopreserved - Ready for recovery
Heterozygous mice are viable and fertile. All homozygous mice die in utero. Macrophages homozygous for this mutation have no transcriptional response to very low-density lipoprotein treatment. No evaluation of lacZ expression is published. The donating investigator reports homozygous mice on this background have a similar, albeit earlier, embryonic phenotype as the exon 4 deleted mutants described in other publications (Barak PNAS 2002 99:303-8, Chawla PNAS 2003 100:1268-73, and Lee Science 2003 302:453-7). Heterozygous mice or homozygous embryo-derived cells may be useful in studies of embryo development, adipocyte physiology, fat metabolism and storage, inflammation, and cancer.
008076 B6.129S4-Traf1tm1Tsi/J
Cryopreserved - Ready for recovery
Mice homozygous for the TRAF1 mutant allele (TRAF1-/-) are viable and fertile. No protein expression from the targeted gene is observed in CD40-stimulated splenocytes isolated from homozygous mice. Homozygous mice on a C57BL/6 congenic background (B6-TRAF1-/-) have abnormal memory T cell survival and impaired influenza virus CD8 T cell responses. Activated B6-TRAF1-/- T cells accumulate increased levels of proapoptotic BH3-only family member Bim, particularly the most toxic isoform, Bims. The donating investigator reports that B6-TRAF1 mutant mice may be difficult to breed and gain more weight than BALB/c-TRAF1 mutant mice.

Homozygous mice on a BALB/c congenic background (BALB/c-TRAF1-/-) exhibit acute liver injury and elevated serum liver enzymes following intratracheal TNF-alpha treatment. Furthermore, activated TRAF1-/- T cells have significantly increased expression of Th2 cytokines (IL-4, IL-5 and IL-13) that el .....

003823 B6.129S4-Ttpatm1Far/J
Cryopreserved - Ready for recovery
Mice that are homozygous null for the Ttpa gene are viable, normal in size and do not display any gross physical abnormalities. The Ttpa protein product is required for the maintenance of proper alpha-tocopherol levels, the major form of vitamin E in plasma and tissues. The absence of Ttpa protein product in homozygous-null animals results in a corresponding 95% reduction in alpha-tocopherol. Low levels of alpha-tocopherol render female mice infertile, a condition that can be addressed with vitamin E supplements. Male fertility is unimpaired. These mice provide a viable model for studying vitamin E deficiency.
006447 B6.129S6(CBA)-Cebpatm1Dgt/J
Cryopreserved - Ready for recovery
Mice carrying this C/EBPalpha "floxed" allele (C/EBPalphaF) are viable and fertile. The floxed allele functions similarly to the wildtype allele. In mice homozygous for C/EBPalphaF and expressing an interferon-inducible Cre recombinase (introduced by breeding to a cre-expressing strain; see Stock No. 003556), C/EBPalpha activity is disrupted, leading to defective myeloid cell development, increased hematopoietic stem cell repopulating activity, and significantly increased myeloblast population in the bone marrow compartment. In combination with an appropriate Cre transgenic strain, these mutant mice may be useful in studies of hematopoietic cell (e.g. myeloid and basophil progenitor cell) development and function, cancer (e.g. acute myeloid leukemia), and alveolar cell differentiation.
006413 B6.129S6-Erap1tm1Luc/J
Cryopreserved - Ready for recovery
Homozygous mutant mice are viable and fertile. The absence of mRNA in splenocyte and of protein in hepatocyte lysates is confirmed via RT-PCR and immunoblot, respectively. Homozygous mutants display reduced cell surface expression of MHC class Ia and Ib molecules, altered presentation of self- and foreign-antigens, and defective CD8+ T-cell responses against class I-presented antigens. These mutant mice may be useful in immunological studies exploring ERAP1's role in vivo in optimizing peptides for presentation by MHC class I molecules.

In an attempt to offer alleles on well-characterized or multiple genetic backgrounds, alleles are frequently moved to a genetic background different from that on which an allele was first characterized. It should be noted that the phenotype could vary from that originally described. We will modify the strain description if necessary as published results become available.

007907 B6.129S6-H2-T23tm1Cant/J
Cryopreserved - Ready for recovery
Mice homozygous for this Qa-1-deficient allele are viable and fertile. Targeted deletion of exons 1-3 of the H2-T23 gene is predicted to completely abrogate Qa-1 expression. Homozygous thymocytes and splenic T cells do not express Qa-1 following concanavalin A stimulation. Qa-1-deficient mice develop exaggerated secondary CD4+ T cell responses to foreign- and self-peptides; this phenotype is attributed to a lack of Qa-1-restricted CD8+ regulatory T cells normally associated with abrogating the secondary responses of CD4+ T cells. As such, homozygous mice are not protected from re-induction of experimental autoimmune encephalomyelitis (EAE) and are susceptible to autoimmune disease. These mutant mice may be useful in studying the role of H2-T23 (Qa-1), a non-classical major histocompatibility complex (MHC) class Ib molecule, in both CD8+ regulatory T cell activity and protection of activated T cells, as well as autoimmune diseases.
004197 B6.129S6-Rac2tm1Mddw/J
Cryopreserved - Ready for recovery
Mice that are homozygous for the targeted mutation are viable, fertile, and normal in size but exhibit phagocytic immunodeficiency. No endogenous gene product (mRNA or protein) was detected by Northern blot analysis, RT-PCR or Western blot analysis. The Rac proteins are a subclass of the Rho family of GTPases, and are involved in actin cytoskeletal organization in cell movement, cell proliferation, kinase signaling pathways, and in superoxide production in phagocytic cells. Neutrophils and mast cells derived from homozygous mice display abnormal actin-based functions: cytoskeleton remodeling ability, adhesion, migration, degranulation, and phagocytosis. Diminished superoxide production in response to some agonists, and reduced total number of leukocytes and neutrophils in peritoneal exudate is observed. As result of functional deficiencies in neutrophil and mast cell populations, these mutant mice are more vulnerable to invasive infection. Slowed growth of mast cells, accompanying redu .....

006039 B6.129S7-Efnb2tm1And/J
Cryopreserved - Ready for recovery
Mice homozygous for this targeted mutation show growth retardation and enlargement of the heart at embryonic day 10 (E10), with 100% lethality occurring around E11. Reporter protein expression patterns are consistent with arterial, but not venous, expression of the endogenous gene; prominent lacZ signal is observed in hindbrain and somites, with lower levels in aorta and heart as early as E8.25. Expression in the yolk sac was first detected at E8.5, and is also observed in nephrogenic mesoderm and branchial arches. Homozygous embryos show defective angiogenic remodeling at the capillary plexus stage in both yolk sac and head. Endothelial vessel support cell differentiation of the yolk sac is also defective. Homozygotes lack myocardial trabecular extensions, and capillary ingrowth into the neural tube does not occur. Heterozygous mice are viable, fertile, exhibit no behavioral defects, and have identical lacZ expression patterns. These mutant mice may be useful in studying .....

006230 B6.Cg-Cebpatm1Dgt Tg(Mx1-cre)1Cgn/J
Cryopreserved - Ready for recovery
Mice homozygous for this C/EBPalpha "floxed" allele (C/EBPalphaF) and hemizygous for the Mx1-cre transgene are viable and fertile, and exhibit no abnormalities in the hematopoietic system. In the absence of cre expression, the C/EBPalphaF allele functions similarly to the wildtype allele. Mx1-Cre transgene expression can be induced by administration of either interferon (alpha or beta) or synthetic double-stranded RNA (such as poly I:C), leading to deletion of the "floxed" gene. Following 3-4.5 weeks of poly I:C treatment, deletion efficiency is greater than 95% in hematopoietic tissues, and C/EBPalpha protein is undetectable in bone marrow. These poly I:C-treated, mice have defective myeloid cell development, increased hematopoietic stem cell repopulating activity, and a significantly increased myeloblast population in the bone marrow compartment. These mutant mice may be useful in studies of hematopoietic cell (e.g. myeloid and basophil progenitor cell) d .....

006194 B6.Cg-Polqtm1Jcs/J
Cryopreserved - Ready for recovery
Mice homozygous for this targeted mutation are viable and fertile, with no gross anatomical or behavioral abnormalities. Homozygotes exhibit significant spontaneous and induced genome instability, and have a 60-80% reduction in somatic hypermutation in B cells. Mutant mice may be useful in studies related to DNA recombination and repair, translesion polymerases, genomic instability, and the mechanisms for generating immune diversity (e.g. somatic hypermutation and immunoglobulin gene class switching).
006922 B6.Cg-Sfpi1tm2Dgt/J
Cryopreserved - Ready for recovery
Mice that are homozygous for this "PU.1F" conditional allele are viable and fertile. When PU.1F mice are bred to mice expressing Cre recombinase, exons 4-5 of the targeted gene are deleted in the cre-expressing tissues in the offspring. These mice may be useful in studying T cell lymphoma, AML and other cancers, as well as transcription factors, hematopoiesis, and the development of multiple cell lineages.

For example, when PU.1F mice are crossed with mice expressing the interferon- or dsRNA-inducible Mx1-cre transgenic mice (see Stock No. 003556), this mutant mouse strain may be useful in studies of hematopoietic stem cells.

NOTE: Despite these mice being backcrossed onto the C57BL/6 genetic background, occasional albino pups may be observed. The donating investigator confirms this observation and suggests the targeted mutation may have an as of yet uncharacterized effect upon coat color .....

006200 B6.Cg-Tnks2tm1.1Yjc/J
Cryopreserved - Ready for recovery
Mice that are homozygous for the targeted mutation are viable and fertile. No gene product (mRNA) is detected by RT-PCR analysis of activated spleen lymphocytes. While neither telomere shortening nor chromosomal abnormalities (even across multiple generations) are observed, homozygous mice have significantly decreased body weight. These mutant mice may be useful in studies of both telomerase function and telomerase-independent pathways which affect development and metabolism.
002319 B6.Cg-Tg(BCL2)22Wehi/J
Cryopreserved - Ready for recovery
Expression of the human BCL2 transgene is restricted to B cell lineage (no T cell expression) in which it enhances cell survival. Hemizygotes show increased numbers of B lymphocytes, Ig-secreting cells and serum Ig, as well as a heightened and prolonged antibody response to immunization. This phenotype is somewhat greater on the BALB/c than on the C57BL/6 background. Hemizygotes on a mixed B6,SJL background (but not on the BALB/c background) develop autoimmune disease characterized by immune complex glomerulonephritis, anti-nuclear antibodies, lymphadenopathy and myocardial infarction. These mice serve as a robust source for the production of B cells and antibodies. Although mice bearing this allele exhibit a mild increase in spontaneous lymphoma and plasmacytoma occurrence (<10% to 18 months) on a (C57BL/6 x SJL)F2 background, on the BALB/c and C57BL/6 backgrounds tumor incidence is insignificant. When this transgene is crossed with an Emu-myc transgene bearing strain (Stock .....

002320 B6.Cg-Tg(BCL2)25Wehi/J
Cryopreserved - Ready for recovery
Expression of the human BCL2 transgene restricted to the T cell lineage (no B-cell expression). Thymocytes, peripheral T-cells and activated T cells from these mice withstand prolonged culture in the absence of growth factors. Cells are resistant to killing by gamma-radiation, glucocorticoids, ionomycin, PMA and sodium azide but NOT complement, cytotoxic T cells or Fas ligand. Hemizygotes have a normal total T-cell count and thymic involution rate but show an enhanced response to immunization. This transgenic line displays no detectable autoimmunity. These mice serve as a robust source for the production of T-cell lines or hybridomas. Also known as 25Wehi or Emu-bcl-2-25.
002321 B6.Cg-Tg(BCL2)36Wehi/J
Cryopreserved - Ready for recovery
Expression of the human BCL2 transgene in both T cell and B cell lineages. This transgenic line combines the characteristics of both Tg(BCL2)22Wehi and the Tg(BCL2)25Wehi lines. Hemizygotes show increased numbers of B lymphocytes, Ig-secreting cells and serum Ig, as well as a heightened and prolonged antibody response to immunization. T-cells withstand prolonged culture in the absence of growth factors and are resistant to killing by gamma-radiation, glucocorticoids, ionomycin, PMA and sodium azide but NOT complement, cytotoxic T cells, or Fas ligand. Hemizygotes have a normal total T-cell count and thymic involution rate but show an enhanced response to immunization. These mice serve as a robust source for the production of B-cells, antibodies T-cell lines or hybridomas.

008111 B6.Cg-Tg(CAG-Ub*G76V/GFP)1Dant/J
Cryopreserved - Ready for recovery
Hemizygous transgenic mice are viable and fertile; they contain a green fluorescent protein (GFP) fused to a constitutively active degradation signal (UbG76V). Transgenic transcripts are detected in all tissues examined; however the G76V substitution leads to its ubiquitination and proteasomal degradation, rather than expression of the GFP fluorescent protein. Following administration of proteasome inhibitors, UbG76V accumulates and GFP-derived fluorescence is readily apparent, evidence of an impaired ubiquitin/proteasome system. Both of the ubiquitin/proteasome system reporter founder lines, UbG76V-GFP/1 (Stock No. 008111) and UbG76V-GFP/2 (Stock No. 008112), may be useful for monitoring the role of ubiquitin/proteasome-dependent proteolysis in diverse disorders, and in efficacy trials for monitoring the effect of compounds on th .....

010511 B6.Cg-Tg(Cd79b-TCL1A)BKTeit/J
Cryopreserved - Ready for recovery
These TCL1-tg transgenic mice express the human T-cell leukemia/lymphoma 1 (TCL1) gene under the control of the mouse CD79B antigen ( Cd79b) minimal promoter. The transgene is expressed in lymphoid (B and T cell) lineage cells and precursors only. The promoter is designed to drive similar levels of expression in B and T cells. Mice hemizygous for the transgene develop mainly mature B cell lymphomas including Burkitt-like lymphoma and diffuse large B cell lymphoma. Occasional chronic B and T lymphocytic leukemias and marginal zone lymphomas also form in these mice. Most mice become clinically (visibly) ill between seven and 13 months, a few as early as four months of age. Mice that are hemizygous for the transgene are viable, normal in size and do not display any gross physical or behavioral abnormalities. Homozygotes are not viable. This mutant mouse strain may be useful in studies of mature B and T cell leukemias and lymphomas.
006229 B6.Cg-Tg(DRE-lacZ)2Gswz/J
Cryopreserved - Ready for recovery
Hemizygous mice are viable, fertile, normal in size, and do not display any behavioral abnormalities. Following adult or in utero exposure with xenobiotic ligands (including 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and polychlorinated biphenyls (PCBs)), lacZ expression is induced in tissues targeted by the toxic compounds; for example, embryonic tissues expressing beta-galactosidase following TCDD treatment in utero include hard and soft palates, genital tubercle, certain facial regions, shoulder, and other tissues). These mice may be useful in studies of toxicology, teratogenic and xenobiotic processes, Per-Arnt-Sim transcription factors, cleft-palate, and as a reporter strain to indicate the temporal and spatial context of transcriptionally active aryl hydrocarbon receptors following agonist exposure in vivo.
008247 B6.Cg-Tg(Ela1-TAg*)289Mjt/J
Cryopreserved - Ready for recovery
Hemizygous T1-147 transgenic mice (harboring the E1-T147 transgene) are viable and fertile, with high-level expression of an N-terminal, truncated (1-147 amino acid), and mutant (does not express the small t antigen) form of simian virus 40 large T antigen (TAg) directed to pancreatic acinar cells by the rat elastase 1 (Ela1 or E1) upstream control region. Hemizygous T1-147 transgenic mice exhibit pancreatic dysplasia in the embryonic pancreas, with cancer progression after birth to primary pancreatic acinar cell tumor formation (100% penetrance). These mice have microadenomas and acinar cell carcinomas present as early as 10 weeks of age, and become moribund or show clear evidence of abdominal distention around 20-30 weeks of age. T1-147 transgenic mice with large tumors develop metastatic disease to the liver and mesenteric lymph nodes. The donating investigator reports that the cancer phenotype of these T1-147 transgenic mice is identical to that of their similar T1-127 trans .....

010914 B6.Cg-Tg(Emu-TXLNA)1Amjr/J
Cryopreserved - Ready for recovery
Mice harboring the pEμSR-IL-14α transgene are viable and fertile, with expression of hemagglutinin-tagged human IL-14α (TXLNA or taxilin alpha) directed predominantly to the B lymphocyte compartment by the Eμ immunoglobulin heavy chain enhancer/SV40 promoter regions (from the pEμSR vector). Human IL-14α expression levels from the transgene are similar to mouse IL-14α expression levels observed in activated T cells/B cells. Transgene expression results in a phenotype with characteristics of systemic lupus erythematosus (SLE) and Sjogren's syndrome. Specifically, transgenic mice exhibit hypergammaglobulinemia (enhanced responses to T-dependent and T-independent antigens), autoantibodies, sialadenitis (infiltration of the parotid glands with lymphocytes), and mild immune-complex mediated nephritis with glomerular IgM deposition. In addition, almost all aged IL-14α-transgenic mice develop large B cell lymphoma (CD5+ B cell lymphoma) similar to .....

002618 B6.Cg-Tg(MMTVtTA)1Mam/J
Cryopreserved - Ready for recovery
The MMTV-LTR was used to target expression of tetracycline-controlled transactivator protein (tTA) to the epithelial cells of secretory organs and skin in transgenic mice. When Tg(MMTVtTA)1Mam transgenic mice were mated to a second transgenic strains carrying either lacZ or luciferase reporter genes coupled to tetracycline-responsive promoter elements (TRE; tetO), nearly uniform expression of the reporter was found in seminal vesicle, salivary gland, and Leydig cells of the double transgenic offspring. More heterogeneous reporter gene expression patterns were observed in mammary epithelial cells and basal cells of the epidermis. Lower reporter gene expression levels also were observed in a broad range of tissues. Transcriptional activation mediated by tTA was up to several hundred-fold and was abrogated after the administration of tetracycline. MMTV-tTA transgenic mice may be useful in experiments examining the roles of biological factors at defined developmental stages in the epitheli .....

006232 B6.Cg-Tg(Scgb1a1-rtTA)1Jaw/J
Cryopreserved - Ready for recovery
Mice hemizygous for the CCSP-rtTA transgene are viable, fertile, normal in size, and do not display any gross physical or behavioral abnormalities. These transgenic mice express the reverse tetracycline-controlled transactivator (rtTA) protein under the control of the rat Scgb1a1, secretoglobin, family 1A, member 1 (uteroglobin), gene promoter. rtTA activity detected in bronchial and type II epithelial cells of lung tissue from adult transgenic mice and in embryos from pregnant females treated with the tetracycline analog doxycycline (dox). In the latter, rtTA-induced expression of a luciferase reporter under the regulation of a tetracycline-responsive promoter (TRE; tetO) has been detected as early as embryonic day 12.5. When hemizygotes are mated to a second transgenic strain carrying a gene of interest under the regulatory control of a TRE, expression of the target gene in the bitransgenic offspring can be regulated by dox; in the presence of dox, transcription of the target .....

010562 B6.Cg-Tg(Wap-ERBB2)229Wzw/J
Cryopreserved - Ready for recovery
Mice that are hemizygous for the transgene are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. These transgenic mice express human ERBB2 (HER2) under the control of the mouse whey acid protein promoter (Wap). The Wap promoter directs expression to the mammary gland and molecular layer of the cerebellum. Mice do not develop spontaneous tumors, but are tolerant to ERBB2 tumor associated antigen, developing tumors after inoculation with ERBB2 expressing tumor cells. Anti-tumor immunity can be induced using aggressive DNA vaccination. This mutant mouse strain may be useful in testing ERBB2-based vaccines and immunotherapies.
008735 B6.Cg-Tg(Wap-cre)11738Mam/JKnwJ
Cryopreserved - Ready for recovery
WAP-Cre transgenic mice are viable and fertile, with expression of P1 Cre recombinase under the control of the mouse Wap (whey acidic protein) promoter. When bred with other mutant mice containing loxP-flanked sequence(s), Cre-mediated recombination will result in deletion of the floxed sequence(s) in mammary gland epithelium. Deletion of floxed sequences is reported in brain tissue from WAP-Cre mice on a mixed genetic background but has not been examined in this strain. Maximum Cre recombinase activity is achieved during pregnancy and lactation, but in virgin mice small numbers of mammary epithelial cells show evidence of estrus cycle-related Cre recombinase activity. These WAP-Cre transgenic mice may be useful in generating conditional mutations in mammary glands for studying mammary physiology and processes such as breast development and breast cancer.

In an attempt to offer alleles on well-characterized or multiple genetic backgrounds, alleles are frequently .....

009344 B6.Cg-Tg(tetO-Ifng)184Pop/J
Cryopreserved - Ready for recovery
The donating investigator reports that homozygous mice are viable and fertile. These TRE/IFN-γ transgenic mice have expression of mouse interferon-gamma (IFN-γ) regulated by the tetracycline-responsive promoter (tetO [also called tetracycline-responsive element (TRE or tet-operator)] fused to the human cytomegalovirus minimal promoter). When mated to a mutant strain expressing reverse tetracycline-controlled transactivator protein (rtTA) or tetracycline-controlled transactivator protein (tTA), expression of IFN-γ may be regulated with the tetracycline analog doxycycline (dox) in the double mutant offspring. Because interferon-gamma (IFN-γ) is a pleiotropic cytokine secreted by activated T-lymphocytes and natural killer cells, these line 184 TRE/IFN-γ mice may be bred to generate bi-transgenic mutant mice with conditional (inducible/reversible) expression of IFN-γ for studying antiviral responses, immune surveillance, inhibiting cellular prol .....

008426 B6.FVB-Tg(TACSTD1)02Leij/J
Cryopreserved - Ready for recovery
These transgenic mice express the human tumor-associated calcium signal transducer 1 gene.

Transgene expression pattern is similar to the observed human pattern in both normal and tumor tissue.

Founder line 02 (BACF2) carries approximately 3 copies of the transgene.

Mice that are hemizygous for the targeted mutation are viable, normal in size and do not display any gross physical or behavioral abnormalities. This mutant mouse strain may be useful in studies of immunological therapies for cancer.

003552 B6129-Tg(Wap-cre)11738Mam/J
Cryopreserved - Ready for recovery
This transgenic strain expresses P1 Cre recombinase under the control of the Wap (whey acidic protein) promoter. In mammary gland tissues, the Wap promoter directs expression to secretory epithelium. A maximum of Cre mediated recombination is achieved during pregnancy and lactation, but recombined cells are still present after involution and complete remodeling of the gland. Cre recombinase expression is not entirely restricted to mammary gland, however. A limited amount of Cre activity has been reported in brain tissue.
004338 B6;129-E2f2tm1Zubi/J
Cryopreserved - Ready for recovery
Mice that are homozygous for the targeted mutation are viable and normal in size. No gene product, mRNA or protein, was detected. At age 15 months mutant mice have a 27% survival rate due to diffuse autoimmune disease that resembles systemic lupus erythematosus (SLE). The phenotype includes splenomegaly by 8-12 weeks of age, glomerulonephritis, accumulated inflammatory infiltrates in the lung, liver, and skin abnormalities such as hair loss, skin wounds, erythema. Anti-dsDNA antibodies are detected in the serum. There are an increased number of mature CD8+ thymocytes and an abnormal accumulation of CD8+ Cd44high Cd69- T effector/memory cells that are autoreactive in peripheral lymphoid organs. E2F2 deficient mice appear to have normal negative selection of thymocytes but demonstrate defects in peripheral tolerance of T lymphoctes (especially Cd8+ T cells) leading to progressive autoimmune disease. This mutant mouse strain may be useful in studies of autoimmunity and may serve as model .....

006099 B6;129-Sfpi1tm1.2Dgt/J
Cryopreserved - Ready for recovery
Mice that are homozygous for the targeted mutation are viable, normal in size, and do not display any gross physical or behavioral abnormalities. Endogenous protein expression is unaffected by the loxP sequences flanking an upstream regulatory region (URE). When bred to mice with a cre recombinase gene under the control of a promoter of interest, the URE of the targeted gene is deleted in the tissue of interest. Deletion of this "floxed" URE may be useful in studying T cell lymphoma, AML and other cancers, as well as transcription factors, hematopoiesis, and development of multiple cell lineages.
006495 B6;129-Trp53bp1tm1Jc/J
Cryopreserved - Ready for recovery
Homozygous "53BP1"-deficient mice are viable and fertile, but exhibit retarded growth and generate reduced litter sizes. Protein from the targeted gene is not detected in the testes (by immunoblot) or in mouse embryonic fibroblasts (MEFs) (by immunofluorescence). Homozygotes are immunocompromised, hypersensitive to whole-body irradiation, and develop thymic lymphomas with higher frequency (8%) compared to wildtype by 4-7 months of age. MEFs from homozygous mutant mice have a defective DNA damage response with impaired Chk2 activation. These mutant mice may be useful in studies of the immune system, cancer, tumor suppression, and DNA damage response pathways.
007226 B6;129P2-Has2tm1Jam/J
Cryopreserved - Ready for recovery
While heterozygous mice are viable and fertile, mice homozygous for this targeted allele die between embryonic day (E)9.5 and E10.5. Embryonic mRNA expression from the targeted gene shows only truncated transcripts of the expected length, with no full-length mRNA expression. Homozygous embryos exhibit severe cardiac and vascular abnormalities, lack hyaluronan (HA), and have yolk sac and somite deformities. Heart deformities can be rescued in explants from homozygous mice following exogenous HA or activated H-Ras treatment. These Has2 mutant mice may be useful in studying embryogenesis and development, specifically cardiac and vascular morphogenesis, as well as cell transformation.
002536 B6;129S-Btktm1Wk/J
Cryopreserved - Ready for recovery
Mice homozygous for the Btktm1Wk targeted mutation are viable and fertile. Homozygous mutant mice show defects in B-cell maturation and activation. This strain has the same phenotype as the spontaneous X-linked immune deficiency mutation (CBA/CaHN-Btkxid/J; Stock No. 001011). See Inbred Strain listing.
007032 B6;129S-Wnt4tm1.1Bhr/BhrEiJ
Cryopreserved - Ready for recovery
This strain contains loxP sites flanking exon 2 of Wnt4 resulting in a Cre-dependent conditional null allele. Homozygotes are normal. Studies by Kobayashi et al., determined that when this conditional allele is exposed to Cre expression by Amhr2tm3(cre)Bhr Mullerian duct regression proceeds normally.
004596 B6;129S1-Smarcb1tm3Sho/J
Cryopreserved - Ready for recovery
This strain contains loxP sites, in opposing orientation, flanking the targeted gene resulting in an reversible Cre-mediated conditional null allele. Mice that are homozygous for this allele are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. When used in conjunction with an inducible Cre recombinase-expressing strain, this strain is useful in generating mutants of the floxed allele that exhibit partial penetrance. In the presence of high levels of Cre protein, the orientation of the floxed allele is continually in a reversible reaction. All progeny resulting from a cross of these mice with Mx-Cre mice developed T-cell lymphoma or rhabdoid tumors at a median onset of age 11 weeks. The rhaboid tumors exhibited in these progeny mice closely resemble human malignant rhaboid tumors.
002115 B6;129S2-Tcratm1Mom/J
Cryopreserved - Ready for recovery
Mice homozygous mice for the Tcratm1Mom targeted mutation are viable and fertile. They are deficient in the alpha beta T-cell receptor. The thymus is devoid of CD4+CD8- and CD4-CD8+ cells. Normal numbers of CD4+CD8+ cells are retained without the IL2 receptor. There are normal numbers of CD4-CD8- cells. ~1% of the thymocytes express the gamma delta TCR. Mice may develop inflammatory bowel disease beginning at ~4-6 months of age.
009046 B6;129S4-Hras1tm1Tyj/J

A G12V mutant form of protein is conditionally expressed from this gene when a floxed stop segment is excised by Cre. This oncogene is involved with the development of Costello syndrome, a neuro-cardio-facio-cutaneous developmental syndrome.
003751 B6;129S4-Ighmtm1Che/J
Cryopreserved - Ready for recovery
Mice homozygous for the Ighmtm1Che allele are viable, fertile and exhibit no apparent defects. While membrane expressed Ighmtm1Che is unhindered, these mice are unable to produce the secreted form of Ighmtm1Che. Increases in some classes of serum Ig is noted in young animals (IgA, IgG2a and IgG3), but these differences are largely absent in the adult animals. The IgG1 antibody response to suboptimal doses of a T cell-dependent antigen is impaired. Conversely, the IgG2a antibody response to a T cell-independent antigen appears augmented. An approximately three-fold increase in B-1 lymphocytes is noted in the spleen and peritoneum.
006238 B6;129S4-Thbs2tm1Bst/J
Cryopreserved - Ready for recovery
Mice homozygous for this targeted mutation are viable and fertile. Multiple analyses has confirmed the absence of protein in embryonic and adult tissue of homozygous mice. Homozygotes exhibit skin disorders (abnormal collagen fiber patterns, reduced tensile strength, increased fragility) and skin fibroblasts have attachment defects. Mice also exhibit an increase in total density/cortical thickness of the long bones, abnormally long bleeding times, and a significant increase in blood vessel density. Homozygous mice exhibit accelerated wound healing after biopsy and accelerated/increased tumor formation following chemically-induced skin carcinogenesis. Mutant mice may be useful in studies of collagen fibrillogenesis in skin and tendons, angiogenesis and vascular pathophysiology, wound healing, chemically-induced tumor progression, and as a potential model for Ehlers Danlos syndrome.

003266 B6;129S7-Epas1tm1Rus/J
Cryopreserved - Ready for recovery
Mice homozygous for the Epas1tm1Rus targeted mutation develop normally until embryonic day 11.5. Beginning at embryonic day 12.5 the ratio of homozygous embryos begins to decline and by day 16.5 there are no viable mutant embryos. Overall morphological development, including the circulatory system, is normal. Of particular interest however, is a pronounced bradycardia in homozygous mutant mice. Catecholamine levels in homozygous mutant mice are also significantly lower than wildtype controls. Administration of the catecholamine precursor DOPS to pregnant females rescues approximately 40% of mutant embryos. Embryos that survive to birth appear runted, fail to nurse, and die within 24 hours of birth. These results suggest a pivotal role of EPAS1 in catecholamine homeostasis. Heterozygous mice from this strain contain a modified lacZ gene in the targeting construct. This characteristic makes this strain useful as a marker for endothelial cells.
006044 B6;129S7-Ephb4tm1And/J
Cryopreserved - Ready for recovery
Mice homozygous for this targeted mutation show growth retardation and lack of blood flow by embryonic day 9.5-10 (E9.5-10), with lethality occurring around this time. Expression of lacZ occurs exclusively in embryonic vascular endothelial cells and is preferentially expressed on veins. Homozygous embryos show defective angiogenic remodeling at the capillary plexus stage in both yolk sac and head. Arrested cardiac morphogenesis and defective myocardial trabecular extensions are also observed. Heterozygous mice are viable, fertile, exhibit no behavioral defects, and have identical lacZ expression patterns. These mutant mice may be useful in studying the cellular and molecular mechanisms underlying vasculogenesis and angiogenesis, the topography of neovascularization, and adult neovascularization, including tumor angiogenesis.

The developmental abnormalities in homozygous mice closely resemble those observed for mutant mice bearing a lacZ-expressing null mutation .....

Cryopreserved - Ready for recovery
These mice possess loxP sites on either side of exons 1-3 in the targeted gene. Mice that are homozygous for this floxed allele are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. When bred to mice that express Cre recombinase, the resulting offspring will have this region deleted in the cre-expressing tissues. (widespread deletion of expression is embryonic lethal). This strain may be useful in studies of development, cell cycles, and cancer in adult mice.

B6;C-GhrhrlitPrkdcscid/BmJ mice are deficient in growth hormone and IGF1 and are useful for determining endocrine dependence of grafted cells and tissues (Beamer et al., 1993, Cancer Research, v53:3741; Friend et al., 2001 Growth Hormone & IGF Research, v11:84).
008080 B6;C3-Tg(CAG-SAC/EGFP)35Rang/J
Cryopreserved - Ready for recovery
Hemizygous SAC transgenic mice have normal fertility, viability, and aging. Widespread expression of the transgene is observed in all tested tissues (with some differential tissue-specific regulation of transgene expression or protein stability reported). The SAC-GFP fusion protein is composed of the cancer-specific proapoptotic effector domain (or SAC domain) of the Par-4 gene fused to an enhanced green fluorescent protein (EGFP). As a result, SAC-GFP transgenic mice have increased resistance to spontaneous liver/spleen and TRAMP-induced prostate tumor development. The protective nature of the transgene appears to be linked to inhibition of NF-kappaB activity and induction of apoptosis. Cells derived from SAC transgenic mice grow normally in short-term culture and presence of the SAC transgene prevents oncogene-mediated cellular transformation. The donating investigator reports that EGFP expression is appropriate for immunoblots, but not sufficient enough for fluorescence of flow cyto .....

006147 B6;FVB-Tg(Sfpi1,-EGFP)7Dgt/J
Cryopreserved - Ready for recovery
Hemizygous mice are viable and fertile with no gross or behavioral abnormalities. Flow cytometry identifies enhanced green fluorescent protein (EGFP) reporter expression in a pattern similar to the endogenous gene; in bone marrow, high expression is observed in myeloid cells, and to a lesser degree in B lymphocytes and erythroid cells. Expression in spleen is consistent with B cells and natural killer cells, while no expression is observed in thymus. These mice may be useful in studies of hematopoietic cell development, transcription factor pathways, and leukemia (including erythroleukemia).
010574 B6;SJL-Tg(Gh1-rtTA)4-3Jek/J
Cryopreserved - Ready for recovery
The donating investigator reports that homozygous mice are viable and fertile. These GH-rtTA transgenic mice have expression of the reverse tetracycline-controlled transactivator (rtTA) protein directed to GH1-producing cells (pituitary somatotropes) by the rat growth hormone (Gh1) promoter. When mated to a mutant strain carrying a gene of interest under the regulatory control of a tetracycline-responsive promoter element (TRE, TetRE or tetO), expression of the target gene in GH1-producing cells may be induced with administration of the tetracycline analog doxycycline (dox) in the double mutant offspring. These GH-rtTA transgenic mice are a Tet-On tool that allows conditional, dox-inducible expression of genes in GH1-producing cells/tissues (such as pituitary somatotropes) and may be useful for studying pituitary hormone secretion and proliferation.
007678 B6;SJL-Tg(KRT14-rtTA)208Jek/J
Cryopreserved - Ready for recovery
Homozygous females and hemizygous males carrying this X-linked K14-rtTA transgene (K14-rtTetA(X) or rtTAX) are viable and fertile. These mice express the reverse tetracycline-controlled transactivator (rtTA) protein under the control of the human keratin 14 promoter. As the transgene is located on the X chromosome, random inactivation of the X chromosome may result in mosaic rtTA expression patterns in female mice. When mated to a second transgenic strain carrying a gene of interest under the regulatory control of a tetracycline-responsive promoter element (TRE or tetO), expression of the target gene in the basal cells of the squamous epithelia and in the outer root sheath of the hair follicles is induced with administration of the tetracycline analog, doxycycline (dox). These K14-rtTA mice provide a Tet-On tool that allows the inducible expression of genes in skin cells.
010573 B6;SJL-Tg(Prl-tTA)6-5Jek/J
Cryopreserved - Ready for recovery
The donating investigator claims homozygous mice are viable and fertile. These Prl-tTA transgenic mice have expression of the tetracycline-controlled transactivator (tTA) protein directed to PRL-producing cells (pituitary lactotropes/mammotropes) by the rat prolactin (Prl) promoter. The donating investigator also reports some expression in testis. When mated to a mutant strain carrying a gene of interest under the regulatory control of a tetracycline-responsive promoter element (TRE, TetRE or tetO), expression of the target gene in the PRL-producing cells may be conditionally abolished with administration of the tetracycline analog doxycycline (dox) in the double mutant offspring. These Prl-tTA transgenic mice are a Tet-Off tool that allows dox-conditional expression of genes in PRL-producing cells/tissues (such as pituitary lactotropes/mammotropes) and may be useful for studying pituitary hormone secretion and proliferation.
010575 B6;SJL-Tg(tetO-Egfr*)2-9Jek/J
Cryopreserved - Ready for recovery
The donating investigator reports that homozygous mice are viable and fertile. These TetRE-EGFR-tr (TRE-EGFR-tr) transgenic mice express a dominant negative, cytoplasmic tyrosine kinase domain-deleted mutant form of epidermal growth factor receptor (EGFR-tr) regulated by the tetracycline operator (tetO; also called tetracycline-responsive element (TRE, TetRE) or tet-operator) and cytomegalovirus minimal promoter. When mated to a mutant strain expressing reverse tetracycline-controlled transactivator protein (rtTA) or tetracycline-controlled transactivator protein (tTA), tissue EGFR-tr expression may be regulated with the tetracycline analog doxycycline (dox) in the double mutant offspring. EGFR-tr expression disrupts subsequent activation of signal transduction pathways that are involved in regulating cellular proliferation, differentiation, and survival. These TetRE-EGFR-tr mice may be bred to generate bi-transgenic mutant mice with conditional (inducible/reversible) expressi .....

009685 B6N.129S1(Cg)-Tnkstm1.1Yjc/J
Cryopreserved - Ready for recovery
Homozygous (TANK1-/-) mice are viable and fertile with no reported developmental or gross physical abnormalities. As exon 1 is deleted from the targeted allele, no full length protein (TANK1) is detected in thymus, testis or spleen tissues. Because the deletion does not encompass the potential alternative promoter between exons 4-5, an alternative transcript and subsequent low molecular weight protein (TANK1a) is expressed in testis (but not in other assayed tissues). These TANK1-mutant mice may be useful for studying the post-translational modification of proteins associated with cell cycle, mitosis, telomere length maintenance/aging, DNA replication/repair, cellular senescence, apoptosis, tumorigenesis, vesicle trafficking, and insulin responses. These TANK1-mutant mice may also be used along with TANK2-mutant mice (Stock No. 006200).

Cryopreserved - Ready for recovery
Experimental allergic encephalitis (EAE) is an autoimmune disease of the nervous system induced by sensitization of experimental animals with homogenates of whole brain and/or spinal cord tissue, myelin, or myelin components. Many of the clinical and histologic aspects of EAE are similar to those of multiple sclerosis (MS), making EAE a useful MS model (Alvord et al., 1984). Mice of different sublines of the BALB/c inbred strain exhibit marked differences in the incidence and severity of EAE induced by immunization with spinal cord homogenate (Hickey et al., 1986) or with myelin proteolipid protein (PLP) (Tuohy et al., 1988). The most severe response to PLP was development in nine of ten BALB/cPt mice of rapid onset, severe clinical disease with limb paralysis accompanied histologically by meningeal and perivascular infiltration by mononuclear and polymorphonuclear lymphocytes, particularly of the spinal cord. At the opposite end of the spectrum, none of ten BALB/ .....

007848 BXSB.129P2(Cg)-Tcratm1Mjo/TheoJ
Cryopreserved - Ready for recovery
Male mice on the BXSB recombinant inbred genetic background (see Stock No. 000740) develop spontaneous autoimmune disease closely resembling the human disease systemic lupus erythematosus (SLE), including moderate lymph node and spleen enlargement, hemolytic anemia, hypergammaglobulinemia, and immune complex glomerulonephritis. This autoimmune phenotype is associated with at least six non-MHC loci (the Y chromosome linked Yaa, Bxs1-4 on chromosome 1 and Bxs6 on chromosome 13) and defined by increased homeostatic proliferation of self-reactive T cells. Because these BXSB-Tcrα-/- mice are homozygous for the Tcrα targeted mutation, they lack αβ+ T cells and do not develop spontaneous lupus symptoms. These BXSB-Tcrα-/- mice may be useful for adoptive transfer experiments for studying the role of T cells in systemic autoimmunity and lupus.

Mice that are homozygous for the targeted mutation are viable, fertile and normal in size. Homozygous mice lack B220+ peripheral blood lymphocytes. This mutant mouse strain represents a model that may be useful in studies related to B-cell immunodeficiency.
008237 C.129S4-Seletm1Dmil/J
Cryopreserved - Ready for recovery
Mice homozygous for this E-selectin mutant allele (E-/-) are viable and fertile with normal circulating leukocyte and platelet profiles. While several transcripts are generated from the mutant locus (due to transcription from the endogenous promoter and/or bidirectional transcription initiated from the pgk promoter in the neo-resistance cassette), these frame-shifted transcripts are non-functional with several predicted stop codons. In contrast to wildtype mice, no protein product is detected in several tissues isolated from LPS-injected homozygous mice. Homozygous mice exhibit abnormal responses to inflammatory stimuli. E-selectin deficiency results in endostatin unresponsiveness (as shown in corneal angiogenesis (mixed B6;129 genetic background) and aortic explant (C57BL/6 congenic background) experiments). These E-selectin mutant mice may be useful in studying inflammation, leukocyte rolling, leukocyte-endothelial adhesion, angiogenesis, and cancer.

Mice homozygous for the TRAF1 mutant allele (TRAF1-/-) are viable and fertile. No protein expression from the targeted gene is observed in CD40-stimulated splenocytes isolated from homozygous mice. Homozygous mice on a BALB/c congenic background (BALB/c-TRAF1-/-) exhibit acute liver injury and elevated serum liver enzymes following intratracheal TNF-alpha treatment. Furthermore, activated TRAF1-/- T cells have significantly increased expression of Th2 cytokines (IL-4, IL-5 and IL-13) that elicit enhanced Th2 responses in vivo. BALB/c-TRAF1-/- T cells exhibit elevated nuclear expression of NFAT-interacting protein (NIP45) and also induce significantly more intense pulmonary inflammation and higher airway hyper-responsiveness in OVA allergic inflammation models. Pulmonary leukocyte recruitment is attenuated following inhalation of lipopolysaccharide in BALB/c-TRAF1-/- mice.

Cryopreserved - Ready for recovery
Transgenic mice are viable, fertile, normal in size, normoglycemic and do not display any gross physical or behavioral abnormalities. Immunohistochemistry reveals pancreatic islet cell expression of the transgene and no expression in the spleen, kidney or thymus. Isolated islets stain normally for insulin and are morphologically indistinguishable from control islets. Additional functional studies found no expression in bone marrow. Histology revealed no insulitis and the single transgenic mice do not become diabetic. T-cell proliferation assays, Cytotoxic Lymphocyte (CTL) assays, and adoptive transfer studies performed using transgenic mice indicate significantly reduced class 1 and class II T-cell responses compared to controls. Hemagglutination inhibition assays of sera from HA primed transgenic mice indicate antibody titers slightly lower but nearly equivalent to HA primed control mice. Antibody titers of all transgenic mice tested were significantly higher than preimmune levels. Wh .....

Cryopreserved - Ready for recovery
Hemizygous transgenic mice are viable, fertile, normal in size, and do not display any gross physical or behavioral abnormalities. These transgenic mice express the reverse tetracycline-controlled transactivator (rtTA) protein under the control of the human SFTPC, surfactant, pulmonary-associated protein C, promoter. rtTA activity is detected in lung peripheral epithelial cells from adult mice and in embryos from pregnant females treated with the tetracycline analog, doxycycline (dox). In the latter, rtTA-induced expression of a luciferase reporter under the regulation of a tetracycline-responsive promoter (TRE; tetO) has been detected as early as embryonic day 10.5. When hemizygotes are mated to a second transgenic strain carrying a gene of interest under the regulatory control of a TRE, expression of the target gene in the bitransgenic offspring may be regulated by dox; in the presence of dox, transcription of the target gene is induced in cells where rtTA is expressed.

Cryopreserved - Ready for recovery
Mice hemizygous for the CCSP-rtTA transgene are viable, fertile, normal in size, and do not display any gross physical or behavioral abnormalities. These transgenic mice express the reverse tetracycline-controlled transactivator (rtTA) protein under the control of the rat Scgb1a1, secretoglobin, family 1A, member 1 (uteroglobin), gene promoter. In situ hybridization detects rtTA gene product (mRNA) in bronchial and type II epithelial cells of lung tissue from adult transgenic mice treated with doxycycline for seven days. Induction of transgene expression is detected as early as postconception day 14 when the pregnant female is treated with doxycycline. When mated to a second transgenic strain carrying a gene of interest under the regulatory control of a tetracycline-responsive promoter element (tetO), expression of the target gene may be regulated by the tetracycline analog, doxycycline (dox); in the presence of dox, transcription of the target gene is induced in cells where rtT .....

Cryopreserved - Ready for recovery
Mice homozygous for this ENU-induced F345I hypomorphic allele (Chaos3) are viable, fertile, and overtly indistinguishable from normal littermates. Homozygous, but not heterozygous, mice have slightly reduced wildtype protein levels in mouse embryonic fibroblasts (MEFs). Whereas Chaos3 heterozygotes show mildly elevated (2- to 5-fold) micronucleus frequencies compared with wildtype, homozygotes have an approximate 20-fold increase with over 7% of erythrocytes containing micronuclei. MEFs from homozygous mice exhibit mild defects (cell proliferation, S phase and G2/M populations), and are highly susceptible to chromosome breakage following treatment with the DNA replication inhibitor aphidicolin. On a congenic C3HeB/FeJ background, greater than 80% of homozygous females exhibit mammary adenocarcinomas with a mean latency of 12 months, while males have no tumor incidence. These Chaos3 mice provide a novel, non-transgenic model of breast cancer, and may be useful for s .....

008711 C57BL/6-H2-T3tm1Luc/J
Cryopreserved - Ready for recovery
The mouse thymus leukemia (TL) antigen is a nonclassical MHC class I molecule encoded by a locus within the MHC complex harboring two genes; H2-T3 and H2-T18. TL binds with high affinity to the CD8αα molecule expressed on the vast majority of intraepithelial lymphocytes (IEL), and the interaction of CD8αα with TL is important for lymphocyte regulation in the intestine. The C57BL/6 genetic background normally has the functional H2-T3d allele and a mutant H2-T18b allele known to result in no expression on the surface of intestinal epithelial cells (IEC). Because these mutant mice harbor a targeted mutation of the H2-T3 gene that abolishes gene function, expression of TL protein (antibody staining) and RNA (RT-PCR) from either locus is absent in IEC and small/large intestine, respectively. These TL-deficient mice may be useful in studying thymus leukemia (TL) antigen-deficiency on CD8αα intraepith .....

Cryopreserved - Ready for recovery
Mice homozygous for this β7 (D146A) targeted mutation are viable and fertile. DNA sequencing confirms an aspartate (D) to alanine (A) substitution at position 146 of the targeted β7 integrin gene. As such, homozygotes have a mutant ADMIDAS (adjacent to metal ion-dependent adhesion site) cation binding/exchange site in the β7 integrin head (A-domain). The resulting imbalance between the non-adhesive and adhesive states of leukocyte integrins skews toward a persistently adhesive state. Homozygous mutants exhibit impaired leukocyte migration, perturbed lymphocyte trafficking in the gut, and reduced T- and B-cell numbers in small/large bowel and gut-associated lymphoid tissues (less T-cells in Peyer's patches (PP), fewer intraepithelial lymphocyte (IEL) and lamina propria lymphocyte (LPL) compartments in the small intestine; and less B-cells in PP and the large intestine). In addition, CD4+CD45RBhigh T cells isolated fro .....

008842 C57BL/6-Tg(Lck-VIPR2)1Ejg/J
Cryopreserved - Ready for recovery
These "VPAC2 R TG mice" (or VPAC2R Tg mice) are viable and fertile, harboring the LCK-huVPAC2 transgene. This transgene has the murine lymphocyte protein tyrosine kinase (Lck) proximal promoter directing persistently high expression of huVPAC2R (human vasoactive intestinal peptide G-protein-coupled receptor 2 [VIPR2 or VIPR2]) primarily to CD4+ T cells (T-helper/inducer cells). As such, expression of huVPAC2R mRNA and protein is highest in spleen and thymus, but also observed in other tissues at much lower levels. The constitutive high huVPAC2R expression on CD4+ T cells is characteristic of levels usually observed only after maximal TCR stimulation. Transgenic mice have elevated blood IgE, IgG1, and eosinophil levels. The effector T cell phenotype is altered; with Th2-bias cytokine profiles (increased IL-4, IL-5, c-maf and junB) associated with altered hypersensitivity states (increased immedi .....

006140 C57BL/6-Tg(TERT)C10Hode/J
Cryopreserved - Ready for recovery
Hemizygous transgenic mice are viable, fertile, and display no gross anatomical or behavioral abnormalities. This "hTERT" transgene carries the complete human telomerase reverse transcriptase (TERT) gene, including at least 11 kb of upstream and 1.5 kb of downstream sequences. The tissue specificity of transgene expression in hemizygous mice recapitulates that of the endogenous hTERT in humans rather than that of the endogenous mouse Tert (mTERT) gene with one exception: in brain, hTERT expression follows the expression profile of the endogenous mTERT gene. These transgenic mice may be useful in studies of telomerase function, organ-specific, differential cis-regulation of mouse versus human genes, as well as in studies of DNA replication and repair mechanisms, human aging, and carcinogenesis.

These transgenic mice express the fusion gene consisting of the amino-terminal region of the human nucleoporin 98kDa (NUP98) fused to the homeodomain of the human homeobox D13 (HOXD13) under the control of the mouse vav1 oncogene (Vav1) regulatory elements. The transgene is expressed specifically in hematopoietic tissues and is detected in thymus, spleen, and bone marrow and not in brain, liver, and kidney by Northern blot analysis of total RNA. The fusion gene product (protein) is detected in thymocytes from transgenic mice by Western blot analysis. Hemizygous transgenic mice develop myelodysplastic syndromes (hematopoietic stem cell disorder) with peripheral blood cytopenia and dysplasia and normocellular to hypercellular bone marrow. By 7 months of age, hemizygotes exhibit leukopenia and anemia. By 14 months of age a subset of hemizygotes succumbs to malignant leukemia or severe anemia and leucopenia.

Cryopreserved - Ready for recovery
HLA-G transgenic (HLA-Gtg) mice are viable, fertile, and harbor two co-injected transgenes; H-2Kb/HLA-G and hβ2m. It was found that co-injecting the hβ2m transgene greatly facilitated expression of the whole HLA-G molecule, implying that endogenous mouse β2m cannot substitute for its human homolog. In addition, the CBA/Ca genetic background has a spontaneous deletion of the genes that encode the structurally/functionally homologous mouse Qa-2 protein, thus experimental results obtained using these HLA-Gtg mice may be attributed directly to transgene expression. Expression of HLA-G expression is observed in pre-implantation embryos and a variety of tissues; expression in the reproductive organs (uterus, ovary, and testes), lung, and liver is much more similar to mouse expression of Qa-2 than to Kb (despite the presence of the H-2Kb promoter and downstream coding sequence), while HLA-G expression in spleen, .....

Mice homozygous for this targeted allele (SirT1co/co) are viable and fertile with a loxP-flanked neomycin cassette just upstream of, and a third loxP site just downstream of exon 4 of the targeted gene. The floxed mutation does not affect the protein expression of the targeted gene in MEF's or mammary tissue from homozygotes. When bred to mice that express Cre recombinase, the resulting offspring have exon 4 (encoding a conserved Sir2 motif) deleted in the cre-expressing tissue(s) (the donating investigator reports that they observe only one recombination event; complete removal of the neomycin cassette and exon 4, leaving a single loxp site remaining). These SirT1co/co mice may be useful in generating conditional mutations for studying the role of estrogen, insulin growth factor-1 (IGF-1), and transcription factors (including NF-kappaB) in mammary gland development, breast cancer, apoptosis, and metabolic diseases.

Mice homozygous for this targeted mutation are viable, fertile, and display no overt developmental or behavioral abnormalities. In mutant mice of a mixed BALB/c, C57BL/6, and 129S6 background, murine pulmonary microvascular endothelial cells (MPMECs) isolated from homozygotes express no endogenous protein. MPMECs from Epha2-deficient mice show impaired ephrin-A1-induced vascular assembly and defective migration both in vitro and in vivo. In addition, MPMECs from homozygous Epha2 mice exhibit decreased angiogenesis and fail to activate Rac1 in response to ephrin-A1 in vivo. Mutant mice on a BALB/c background that were transplanted with metastatic mammary adenocarcinoma cells showed impaired tumor progression, angiogenesis and metastasis to the lung, compared with wildtype littermate controls. These mutant mice may be useful in studies of postnatal angiogenesis (endothelial cell migration, assembly into new tubules, and cytoskeletal regulation), or as a .....

In addition, stable and uniform EGFP expression is observed in differentiated progeny of transplanted hematopoietic stem cells (HSC) isolated from ROSA26-EGFP mice. These ROSA26-EGFP BAC transgenic mice may be useful for fluorescent labeling of cells and tissues both in vivo and in vitro, are suitable for use in histological preparations, and are appropriate as a source of fluorescently labeled donor cell populations (such as tracking hematopoietic cell fate in transplant recipients).

In an attempt to offer alleles on well-characterized or multiple genetic backgrounds, alleles are frequently moved to a genetic background different from that on which an allele was first characterized. It should be noted that the phenotype could vary from that originally described. We will modify the strain description if necessary as publish .....

008338 CByJ.B6(Cg)-Rag2tm1Cgn/J
Cryopreserved - Ready for recovery
Mice homozygous for the RAG-2fl allele are viable and fertile, with loxP sites flanking exon 3 of the targeted gene. When bred to mice that express Cre recombinase, the resulting offspring will have this region (coding for the entire RAG-2 protein) deleted in the cre-expressing tissue(s). These RAG-2fl mice may be useful in generating conditional mutations for studying the role of RAG-2 in B and T cell development (including cancer and toxicology research as a xenograft/transplant host), T and B cell receptor (V(D)J) recombination, hematopoiesis, hematology, immunology, and inflammation research.

For example, when bred to a strain with inducible Cre recombinase expression in liver and lymphocytes (see Stock No. 003556), this mutant mouse strain may be useful in studies of B and T cell development.

000711 CByJ.Cg-Foxn1nu/J
Cryopreserved - Ready for recovery
The two main defects of mice homozygous for the nude spontaneous mutation (Foxn1nu, formerly Hfh11nu) are abnormal hair growth and defective development of the thymic epithelium. Although the mice appear hairless, they are born with functional but faulty hair growth follicles. Hair growth cycles and patterns are evident especially in pigmented mice but the faulty follicles do not allow the hair to properly erupt. Homozygous pups can be identified as young as 24 hours by their lack of whiskers or poorly developed, crinkled whiskers. Nude mice are also athymic caused by a developmental failure of the thymic anlage. Consequently, homozygous nude mice lack T cells and suffer from a lack of cell-mediated immunity. However there is not a defect in T-cell precursors, and under the right conditions some functional mature T cells can be found especially in adult mice. Because of a defect in helper T-cell activity, responses to thymus-dependent antigens when d .....

Cryopreserved - Ready for recovery
These L2G85.DBA/1 mice harbor the CAG-luc-eGFP L2G85 transgene. Homozygous mice are viable and fertile, with widespread expression of firefly luciferase and enhanced green fluorescent protein directed by the CAG promoter (human cytomegalovirus immediate early promoter enhancer with chicken beta-actin/rabbit beta-globin hybrid promoter). Bioluminesence is detected in heart, spleen, muscle, pancreas, skin, thymus and bone marrow. Luciferase activity is not detected in mature erythrocytes, although low levels are detected in erythrocyte precursors and varying levels of activity in all leukocyte subsets tested. Homozygotes have no reported gross physical or behavioral abnormalities. Following luciferin injection, luciferase expression is generally greater in males than females. GFP fluorescence is detected in skin (upper epidermal layers) by fluorescence microscopy. The Donating Investigator reports that for the FVB-Tg(CAG-luc,-GFP)L2G85Chco/J (STOCK#8450) strain, no GFP fluorescence .....

006125 FVB-Tg(H2-D-Il15)3304Clgr/J
Cryopreserved - Ready for recovery
Mice hemizygous for this transgene are viable and fertile. The transgene was designed to optimize the overexpression of secreted, mature interleukin-15. Transgenic IL-15 expression has a similar tissue distribution as the endogenous gene, but at a significantly higher level. IL-15 protein is detectable in the serum from most mutant, but not from wildtype, mice. Mutant mice develop a progressive alopecia by as early as 5-6 weeks of age, with skin lesions appearing over time. While all transgenic mice exhibit early polyclonal/benign expansion of natural killer and memory CD8+ T lymphocytes (T/NK), two distinct phenotypes emerge over time: approximately 70% of the transgenic mice will exhibit polyclonal T/NK progression in multiple tissues, while the remaining 30% are characterized by T/NK clonal expansion in multiple tissues and acute lymphoblastic leukemia (T/NK ALL). Both T/NK phenotypes are fatal within the first year of life. Mice harboring this transgene may be useful in .....

006822 FVB-Tg(KRT14-MAP2K1/Esr1)12Pkha/J
Cryopreserved - Ready for recovery
Mice hemizygous for this "K14-Mek1:ER" transgene are viable and fertile, with expression of the Mek1:ER fusion protein (a constitutively active mutant region from human mitogen activated protein kinase-kinase 1 (Mek1R4F; containing an amino-terminal deletion of aa 32-51 and the S218E/S222D substitutions) fused at its carboxy terminal with the G525R mutant murine estrogen receptor ligand binding domain (ERTM)) directed to epidermis by the human keratin 14 promoter. Because of the ERTM region of the fusion protein, Mek1:ER is restricted to the cytoplasm and the biochemical activity of the Mek1:ER fusion gene can be induced following tamoxifen administration. For example, induction of this constitutively active form of human Map2k1 (Mek1R4F) promotes the undifferentiated, proliferative phenotypic characteristics observed in epidermal neoplasia in as few as 5 days (including hyperplasia, increased levels of phosphorylated ERK1/2, increased mitot .....

008537 FVB-Tg(Tek-cre)2352Rwng/J
Cryopreserved - Ready for recovery
These transgenic mice express the Cre recombinase under the control of the mouse Tek, endothelial-specific receptor tyrosine kinase (also known as Tie2), promoter. Cre recombinase expression is detected in most endothelial cells and blood islands of the extraembryonic mesoderm by embryonic day (ED)7.5 and in the dorsal aorta by ED8.5. Especially high levels of expression are seen in head vasculature by ED9. When crossed with reporter strains (expressing beta-galactosidase or alkaline phosphatase), recombination is detected in all blood vessels and some blood cells examined at ED11.5, which indicates that Cre activity occurs in early vascular progenitor cells, endothelial cells and some hematopoietic cells. Mice homozygous for the transgene are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. This strain represents an effective tool for generating endothelial cell specific-targeted conditional mutations.
008695 FVB-Tg(tetO-MET)23Rwng/J
Cryopreserved - Ready for recovery
These transgenic mice express the human MET (met proto-oncogene (hepatocyte growth factor receptor)) gene under the control of a tetracycline-responsive promoter element (TRE or tetO). When bred with another transgenic mouse expressing reverse tetracycline-controlled transactivator protein (rtTA) or tetracycline-controlled transactivator protein (tTA), a bitransgenic animal can be produced that has tissue-specific expression of MET that can be regulated with the tetracycline analog, doxycycline. When bred to mice carrying the transgene LAP-tTA, (see Stock No. 003563 for example), the resulting bi-transgenic mice have inducible overexpression of MET in hepatocytes and represent an effective tool for studying hepatocellular carcinoma.
006225 FVB.Cg-Tg(SFTPC-rtTA)5Jaw/J
Cryopreserved - Ready for recovery
Hemizygous transgenic mice are viable, fertile, normal in size, and do not display any gross physical or behavioral abnormalities. The donating investigator reports that homozygous transgenic mice are not viable. These transgenic mice express the reverse tetracycline-controlled transactivator (rtTA) protein under the control of the human SFTPC, surfactant, pulmonary-associated protein C, promoter. rtTA activity is detected in lung peripheral epithelial cells from adult mice and in embryos from pregnant females treated with the tetracycline analog doxycycline (dox). In the latter, rtTA-induced expression of a luciferase reporter under the regulation of a tetracycline-responsive promoter (TRE; tetO) has been detected as early as embryonic day 10.5. When hemizygotes are mated to a second transgenic strain carrying a gene of interest under the regulatory control of a TRE, expression of the target gene in the bitransgenic offspring can be regulated by dox; in the presence of dox, tra .....

Cryopreserved - Ready for recovery
Mice hemizygous for the CCSP-rtTA transgene are viable, fertile, normal in size, and do not display any gross physical or behavioral abnormalities. These transgenic mice express the reverse tetracycline-controlled transactivator (rtTA) protein under the control of the rat Scgb1a1, secretoglobin, family 1A, member 1 (uteroglobin), gene promoter. rtTA activity is detected in bronchial and type II epithelial cells of lung tissue from adult transgenic mice and in embryos from pregnant females treated with the tetracycline analog doxycycline (dox). In the latter, rtTA-induced expression of a luciferase reporter under the regulation of a tetracycline-responsive promoter (TRE; tetO) has been detected as early as embryonic day 12.5. When hemizygotes are mated to a second transgenic strain carrying a gene of interest under the regulatory control of a TRE, expression of the target gene in the bitransgenic offspring can be regulated by dox; in the presence of dox, transcription of the targ .....

006209 FVB.Cg-Tg(Tal1-tTA)19Dgt/J
Cryopreserved - Ready for recovery
Hemizygotes are viable, fertile, normal in size, and do not display any behavioral abnormalities. Hemizygotes express tetracycline-controlled transactivator protein (tTA) in bone marrow hematopoietic stem cells (HSC) and in common myeloid progenitors (CMP)). tTA activity also is detected in lung. Little to no tTA activity is detected in thymus, lymph node, intestine or spleen. When bred to other transgenic mice carrying a gene of interest coupled to a tetracycline-responsive promoter element (TRE; tetO), expression of the target gene in the bitransgenic offspring can be induced by withdrawal of tetracycline or doxycycline. This strain represents an effective tool for generating bitrangenic animals to study inducible gene expression in blood stem and progenitor cells.

These mice were originally designed to be bred with transgenic mice harboring a TRE-BCR-ABL1 transgene (Stock No. 006202), creating bitransgenic offspring as a mo .....

010634 FVB/N-Tg(Acta2-RAC1*G12V)33Pjgc/J
Cryopreserved - Ready for recovery
Mice that are homozygous for the transgene are viable, fertile and normal in size. Males develop reddish, discolored tail lesions beginning at 8 months of age. Females develop tumors at approximately 18 months. Tumors exhibit many characteristics of Kaposi's sarcoma including an increase in spindle cells without identifiable vascular structures, slits containing red blood cells and hemosiderin between cells, expression of phenotypic markers (such as CD31, CD34, and von Willebrand factor), and an association with male gender. Transgenic mice exhibit moderate hypertension, left ventricular hypertrophy, accelerated wound healing and increased vascular formation in response to wound grafting. This mutant mouse strain may be useful in studies of blood pressure, angiogenesis, wound healing, oxidative stress and Kaposi's sarcoma.
002437 FVB/N-Tg(MMTV-Notch4)3Rnc/J
Cryopreserved - Ready for recovery
Male mice transgenic for the Notch4 gene (previously called Int3) are sterile, and females fail to lactate. Mammary tissue of females does not develop completely, exhibiting dramatic inhibition of alveolar-lobular development and reduced penetration of the mammary fat pad by ductal epithelium. Glandular epithelia of tissues expressing the activated form of Notch4 generally display severe ductal hyperplasia. Salivary glands fail to differentiate completely. Male transgenic mice exhibit severe epididymal hyperplasia, which is thought to be the cause of their sterility. Both male and female mice develop focal adenomas of the mammary and salivary glands.
006875 FVB/N-Tg(Tagln-rtTA)E1Jwst/J
Cryopreserved - Ready for recovery
Transgenic SM22-rtTA mice are viable and fertile. These mice express the reverse tetracycline-controlled transactivator (rtTA) protein under the control of the murine SM22-alpha (SM22α or transgelin) promoter. When hemizygotes are mated to a second transgenic strain carrying a gene of interest under the regulatory control of a tetracycline-responsive promoter element (TRE; tetO), expression of the target gene in the bitransgenic offspring is inducible in smooth muscle cells with administration of the tetracycline analog, doxycycline. These SM22-rtTA mice provide a "Tet-On" tool that allows the inducible expression of genes in smooth muscle cells.
006202 FVB/N-Tg(tetO-BCR/ABL1)2Dgt/J
Cryopreserved - Ready for recovery
Hemizygotes are viable, fertile, normal in size, and do not display any behavioral abnormalities. Transgene expression is directed by the tetracycline-responsive element (TRE; tetO). When hemizygotes are bred with another transgenic mouse expressing either reverse tetracycline-controlled transactivator protein (rtTA) or tetracycline-controlled transactivator protein (tTA) under the regulation of tissue-specific promoters , BCR-ABL1 fusion protein expression can be regulated in the appropriate tissue of the bitransgenic offspring with the tetracycline analog, doxycycline.

These mice originally were designed to be bred with transgenic mice harboring a Tal1-tTA transgene (see Stock No. 006209), creating double transgenic offspring as a model for studies of the Philadelphia chromosome and inducible chronic myeloid leukemia.

When bred to a strain expressing tTA in the epithelial cells of secretory organs and skin (see Stock .....

003076 NMRI/Gat-Tg(MGMT)3Bec/J
Cryopreserved - Ready for recovery
This strain carries a transgene that directs skin-targeted overexpression of the human DNA repair protein MGMT (O6-methylguanine-DNA methyltransferase). The transgenic strain exhibits a significantly reduced incidence of alkylation-induced skin tumors. It may be used (1) to investigate the role of the MGMT DNA repair enzyme in protecting cells from premutagenic and precarcinogenic O6-alkylguanine lesions, (2) as an indicator system for O6-alkylguanine generating carcinogens (e.g. N-nitrosamines, N-nitrosoureas) and (3) to explore the pathophysiological significance of these lesions for various end points. Moreover, skin tumors induced on these transgenic mice may be used as a model for chemotherapy resistant tumors expressing high levels of MGMT.
009618 NOD.129(B6)-Il12btm1Lky/JbsJ
Cryopreserved - Ready for recovery
Mice homozygous for this bicistronic "yet40" allele are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. The IRES-EYFP is inserted downstream of the endogenous stop codon, allowing for normal expression of the endogenous gene and simultaneous EYFP reporter expression. ELISA assays confirm that p40 protein is expressed at similar levels in homozygous mutant and wildtype mice. The EYFP reporter marks dendritic cell (DC) and macrophage lineage cells that produce p40 following stimulation with toll-like receptor (TLR) ligands both in vivo and in vitro. NOD congenic female mice carrying this bicistronic "yet40" allele experience slightly accelerated diabetes. These mice may be useful for labeling activated IL12/23 p40 expressing cells in studies of immunology and immunity, TLR signal cascades, cancer immunity, vaccine development and diabetes.
004083 NOD.129(B6)-Prkdcscid Iduatm1Clk/J
Cryopreserved - Ready for recovery
At birth, mice that are homozygous null for the Idua gene are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. No alpha-L-iduronidase enzyme activity or mRNA is detected. By three weeks of age, homozygous null mice develop a flattened facial profile and a thickening of digits. Defective bone formation is noticeable by fifteen weeks, characterized by a broadening and thickening of long bones. Evidence of lysosomal storage disorder is apparent in cells of the reticuloendothelial system at four weeks. By eight weeks progressive evidence of lysosomal storage is seen in Kupffer cells, splenic sinusoidal lining cells, chondrocytes, glial and Purkinje cells. This animal model is suitable for use in studies investigating the lysosomal storage disorder mucopolysaccharidosis type I (MPS I).
004673 NOD.129(B6)-Rag1tm1Mom Cd80tm1Shr/JbsJ
Cryopreserved - Ready for recovery
The NOD.129(B6)Rag1tm1MomCd80tm1Shr/JbsJ homozygous mice fail to produce T or B cells. Mice homozygous for both Rag1tm1Mom and Cd80tm1Shr are viable and fertile and exhibit no signs of diabetes due to the absence of lymphocytes.

On the NOD background Cd80tm1Shr alone exacerbates diabetes onset when compared to standard NOD controls. When injected with proteolipid protein in Complete Freund's Adjuvant, NOD mice homozygous for the Cd80tm1Shr/JbsJ mutation alone develop similar though slightly milder, experimental autoimmune encephalomyelitis (EAE) when compared with NOD controls.

NOD.129(B6)-Rag1tm1MomCd80tm1Shr/JbsJ are valuable for unraveling the co-stimulatory pathways of T cell activation as it relates to autoimmune diseases and organ transplantation.

005878 NOD.129(Cg)-Cd44tm1Hbg/J
Cryopreserved - Ready for recovery
Mice that are homozygous for the targeted mutation are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. No gene product (mRNA or protein) is detected. Although lymphocyte development appears unremarkable, irregularities are observed in lymphocyte trafficking. Tail-injected lymphocytes derived from null animals exhibit an impaired ability to traffic to peripheral lymph nodes, and to a much greater degree, the thymus. Transcription and translation of the targeted allele subsequently lead to the synthesis of the lacZ protein under control of the 5' regulatory elements of the endogenous locus in all cells and tissues normally expressing one or several of the CD44 isoforms.

In an attempt to offer alleles on well-characterized or multiple genetic backgrounds, alleles are frequently moved to a genetic background different from that on which an allele was first characterized. It should be noted that the phenotype could vary f .....

004222 NOD.129P2(B6)-Il4tm1Cgn/DvsJ
Cryopreserved - Ready for recovery
Complete Freund's adjuvant (CFA) induced suppression of diabetes in NOD mice has been associated with a shift to Th2 cytokine production. NOD mice deficient in IL4 were created to investigate the role of IL4 in this shift. Mice homozygous for the Il4tm1Cgn targeted mutation are viable and fertile. T and B cell development is normal but IgG1and IgE levels and the ability of homozygous mutant mice to produce Th2-derived cytokines are significantly reduced. IL4 deficient NOD mice develop IDDM with the same incidence as standard NOD/Lt controls, and there is no change between IL4 deficient and wildtype NOD in disease protection conferred by treatment of bacillus Calmette-Guerin vaccine (BCG) or CFA. Both IL4 deficient and wildtype NOD mice are significantly protected from insulitis by treatment of CFA but not by treatment of BCG. (Serreze et al 2001)
004444 NOD.129P2(C)-Tcratm1Mjo/DoiJ
Cryopreserved - Ready for recovery
NOD mice homozygous for the Tcratm1Mjo targeted mutation lack alpha beta T cells, and therefore, are completely protected from diabetes development. Because of the complete elimination of alpha beta T cells, these mice are useful in adoptive transfer experiments (as in Hoglund et al. 1999).
014163 NOD.129S2(B6)-Alox15tm1Fun/NadlJ
Cryopreserved - Ready for recovery
Homozygous Alox15tm1Fun (12/15-LO-deficient) mutant mice are viable and fertile. Macrophages of 12/15-LO-deficient mice exhibit an absence of 12/15-LO by Rt-PCR and immunoblotting; and protein is undetectable. Diabetes incidence of mutant mice is significantly reduced compared to NOD and is reported at 2% of females and 0% of males by 7 months of age. When challenged with Glucose Tolerance Test, non-diabetic, 8-month-old, 12/15-LO-deficient females cleared glucose more efficiently than age matched, non-diabetic NOD females. Histological evaluation of the pancreas from 30 week old females shows significantly reduced insulitis and beta cell damage, compared to age-matched NOD females.

This model is useful to further study the role of Alox15 in macrophage regulation and autoimmune diabetes.

004639 NOD.129S2(B6)-Ighmtm1Cgn/DoiJ
Cryopreserved - Ready for recovery
NOD mice homozygous for the Ighm tm1Cgn allele do not express membrane-bound IgM. Ighm deficient mice lack mature B-cells, although some B-cells may be produced using a C gene other than mu. These mice are virtually free of insulitis: at most, presence of only perivascular/periductal leukocytes is detected. No intra-islet infiltrates are found. Results indicate that insulin dependant diabetes mellitus (IDDM) is not delayed, but prevented because of a lack of B cell autoreactive T cell responses. Therefore, the elimination of B lymphocytes by congenic transfer of the Ighm tm1Cgn mutation is sufficient to block IDDM development in an otherwise susceptible NOD mouse strain. (Kitamura 1991, Serreze 1996)

Cryopreserved - Ready for recovery
Tg(IL3)1Ygy, Tg(CSF2)2Ygy, and Tg(KITLG)3Ygy encode porcine interleukin 3 (IL3), Porcine granulocyte macrophage-colony stimulating factor (CSF2, commonly designated GM-CSF) and soluble Porcine stem cell factor (KITLG, commonly designated sSCF) respectively. All three are individually driven by the human cytomegalovirus promoter. These three transgenes were co-injected and they co-segregate. RT-PCR detects transgenic expression of porcine IL-3, CSF2 and KITLG in bone marrow and spleen in NOD.Cg Prkdc scid-Tg(IL3)1Ygy Tg(CSF2)2Ygy Tg(KITLG)3Ygy mice. Porcine IL3, CSF2, and KITLG are present in the serum of these mice in levels that can be detected by ELISA. NOD.Cg Prkdc scid-Tg(IL3)1Ygy Tg(CSF2)2Ygy Tg(KITLG)3Ygy/YgyJ not only provide a system in which long-term porcine tissue and stem cell engraftment can be achieved (Abe et al, 2002) but also is a useful tool for evaluating donor-specific tolerance induction by mixed chimerism across xenogeneic ba .....

005345 NOD.Cg-Cd38tm1Lnd Prkdcscid/LtJ
Cryopreserved - Ready for recovery
CD38 is an ADP-ribosyl cyclase/cyclic ADP-ribose hydrolase. This ubiquitously expressed ectoenzyme is the major NAD hydrolase in mice. NOD/Lt mice homozygous for the Cd38tm1Lnd targeted allele develop accelerated Type 1 diabetes associated with an ART2 (T cell ADP-ribosyltransferase)-dependent and NAD-mediated loss of regulatory CD4+CD25+ Foxp3+ and CD4+iNKT cells (Chen, J. et al 2006; Chen, Y.G et al 2006). Combining the Prkdcscid mutation with the Cd38tm1Lnd targeted allele completely prevents diabetes development. For investigators wishing to study the role of CD38 in beta cell biology, the presence of the Prkdcscid allele provides insultis-free islets for analysis. Congenic, doubly homozygous NOD.Cd38tm1Lnd Prkdcscid mutant mice exhibit no significant difference in glucose tolerance when compared to NOD or NOD. Prkdcscid, thus not suppor .....

Cryopreserved - Ready for recovery
NOD.Cg-Ighmtm1Cgn Tg(IghelMD4)4Ccg/DvsJ (NOD.IgHEL Ighm-deficient) mice are viable, fertile, normal in size, and do not display any gross physical or behavioral abnormalities. Because these mice are Ighm-deficient, they do not express endogenous IgM. All B lymphocytes in NOD.IgHEL Ighm-deficient mice express Ig molecules specific for hen egg lyzozyme (HEL). There is no significant difference in the total number of B and T lymphocytes between NOD.IgHEL Ighm-deficient and NOD.IgHEL (Stock No. 006345) mice. The incidence of diabetes in transgenic vs. non-transgenic NOD.Ighm-deficient mice is similar by 21 weeks of age, (16.7% vs. 13.6%, respectively). Histological evaluation of 12 week old NOD.IgHEL Ighm-deficient mice shows that most mice have low levels of insulitis compared to NOD/ShiLt control mice, although an occasional animal had extensive insulitis.

Mice homozygous for the Il10tm1Cgn targeted mutation are viable and fertile when housed under SPF conditions. This mutant develops type 1 diabetes at the same rate as the NOD/Lt parental strain. The Il10 tm1Cgn mutation also renders this NOD/Lt stock susceptible to colitis (although not as severe as other strains of Il10 deficient mice) when maintained under standard housing conditions.

Cryopreserved - Ready for recovery
These mice are characterized by pancreatic beta cells that express a rat insulin promoter (Rip) regulated transgene encoding the human CD80 T cell co-stimulatory molecule. They are an excellent source of MHC class I positive, CD80 transgene-expressing islet cells, a potent antigenic reagent for propagating diabetogenic CD8+ T lymphocytes derived from NOD mice in vitro. The presence of the Prkdcscid allele eliminates the possibility that isolated islet cells will introduce contaminating T lymphocytes onto cultures.

003843 NOD.Cg-Prkdcscid Tg(Ins2-GAD2)1Lt/LtJ
Cryopreserved - Ready for recovery
NOD.Cg-Prkdcscid Tg(Ins2-GAD2)1Lt/LtJ transgenic mice are viable, fertile, normal in size, and do not display any gross physical or behavioral abnormalities. Transgenic mice are homozygous for Prkdcscid and are free of potential insulitic lymphocytes resulting in diabetes resistance. Similar to the NOD/Lt-Tg(Ins2-GAD2)1Lt (Stock No. 003074) the transgene inserted into Chromosome Y, thus only males are transgenic (Bridgett et al, Diabetes 1998 47:1848-56).

This model provides a tool for studying the role of GAD2 as a islet autoantigen in the NOD mouse model of Type 1 diabetes.

003844 NOD.Cg-Prkdcscid Tg(Ins2-GAD2)2Lt/LtJ
Cryopreserved - Ready for recovery
NOD.Cg-Prkdcscid Tg(Ins2-GAD2)2Lt/LtJ transgenic mice are viable, fertile, normal in size, and do not display any gross physical or behavioral abnormalities. Transgenic mice are homozygous for Prkdcscid and are free of potential insulitic lymphocytes resulting in diabetes resistance. Delayed diabetes onset is observed when splenic lymphocytes from 5 week old pre-diabetic NOD females are adoptively transferred into NOD transgenic mice homozygote for Prkdcscid when compared to adoptive transfers into control NOD females. Similar to the NOD/ShiLt(Cg)-Tg(Ins2-GAD2)2Lt/J (Stock No. 005870) homozygous transgenic mice are developmentally lethal due to the transgene insertion site (Bridgett et al, Diabetes 1998 47:1848-56).

This model provides a tool for studying the role of GAD2 as an islet autoantigen in the NOD mouse model of Type 1 diabetes.

016148 NOD.Cg-Prkdcscid Alox15tm1Fun/NadlJ
Cryopreserved - Ready for recovery
Mice homozygous for Alox15tm1Fun and Prkdcscid, commonly referred to as NOD.scid12LOKO, are viable and fertile. NOD.scid12LOKO mice injected with NOD/ShiLtJ, Stock No. 001976, splenocytes do not develop diabetes. This strain may be useful in adoptive transfer studies.
002570 NOD.Cg-Prkdcscid B2mtm1Unc/J
Cryopreserved - Ready for recovery
Mice homozygous for both the B2mtm1Unc and Prkdcscid (commonly referred to as scid) mutations on the NOD/ShiLtSz background are class I deficient, B and T cell deficient, C-5 deficient (Hc0), and have low NK cells. This strain is an ideal model for xenograft transplantation studies and is an excellent source for insulitis-free, MHC class I-negative islets for transplantation studies.
006605 NOD.Cg-Prkdcscid Emv30b Tg(HLA-A/H2-D/B2M)1Dvs/DvsJ
Cryopreserved - Ready for recovery
Although NOD mice that carry this transgene (Stock No. 006604) develop diabetes significantly earlier than do NOD/ShiLtDvs (NOD) controls, this transgenic strain harbors the Prkdcscid mutation (characterized by an absence of functional T cells and B cells), and therefore does not become diabetic. This strain is useful for adoptive transfer experiments, and as a source of insulitis free pancreatic islets.
005053 NOD.Cg-Prkdcscid Gusbmps/SndsJ
Cryopreserved - Ready for recovery
Mice homozygous for the mps allele exhibit skeletal dysplasia as well as cognitive, hearing and visual deficits. Lifespan of the homozygotes is approximately six months. Homozygotes lack the lysomal enzyme, beta-glucoronidase, and, as a result, glycosaminoglycans accumulate in tissues throughout the body. This strain is a model for the human lysomal storage disease, mucopolysaccharidosis type VII. On the NOD-Prkdcscid background, this strain can be used for xenotransplantation experiments and cell trafficking studies (Hofling et al., 2003).
005589 NOD.Cg-Prkdcscid H2-Ab1tm1Doi/SzJ
Cryopreserved - Ready for recovery
These mice have no MHC class II expression which makes them useful to facilitate the engraftment of human immune cells.
006609 NOD.Cg-Prkdcscid Tg(HLA-A2.1)1Enge/DvsJ
Cryopreserved - Ready for recovery
Although transgenic NOD mice develop diabetes significantly earlier than do NOD/ShiLtDvs (NOD) mice, this transgenic strain harbors the Prkdcscid mutation (characterized by an absence of functional T cells and B cells) and therefore does not become diabetic. This strain is useful for adoptive transfer experiments and as a source of insulitis free pancreatic islets.
007840 NOD.Cg-Prkdcscid Tg(Ins2-CD86)12B70Flv/FswJ
Cryopreserved - Ready for recovery
Tg(Ins2-CD86)12B7 mice homozygous for the Prkdcscid mutation are viable, fertile, normal in size, and do not display any gross physical or behavioral abnormalities. Transgenic mice express the human CD86 T cell co-stimulatory protein under the control of the rat insulin promoter (Ins2). RT-PCR analysis detects human CD86 mRNA expression in the pancreas. Very low expression levels are also detected in the kidney and thymus of some but not all transgenic mice. Immunohistochemistry indicates that transgenic CD86 protein expression is restricted to the Islets of Langerhans. Transgenic, Prkdcscid homozygous mice lack functional T cells and B cells, and do not become diabetic.

In the absence of the Prkdcscid mutation, NOD-Tg(Ins2-CD86), transgenic mice experience accelerated diabetes. Diabetes onset in male and female transgenic NOD-Tg(Ins2-CD86) mice starts at 8 weeks of age and 85-90% of the mice ultimately become d .....

004347 NOD.Cg-Rag1tm1Mom Tg(TcraAI4)1Dvs/DvsJ
Cryopreserved - Ready for recovery
The rearranged Tcra transgene expressed in these mice is derived from the pancreatic beta cell-reactive CD8 T lymphocyte clone AI4. The presence of the nonfunctional Rag1tm1Mom allele renders mice incapable of rearranging endogenous T cell receptor genes. When crossed with strain NOD.Cg-Tg(TcrbAI4)1DvsRag1tm1Mom/DvsJ (004348), the resulting animals that carry both the alpha and beta AI4 TCR transgenes exhibit an accelerated development of insulin-dependent diabetes mellitus (IDDM). Additionally, transgenic animals bearing both TCR transgenes offer a source of CTL precursors useful in examining the diversity of beta cell peptides recognized by the autoreactive CD8+ T lymphocytes contributing to the earliest phase of IDDM development. Homozygous mice are viable and fertile.
006024 NOD.Cg-Rag1tm1Mom H2-Ab1tm1Gru Tg(CD4,HLA-DQA1,HLA-DQB1)N8Ell/EllJ
Cryopreserved - Ready for recovery
Rag1 and H2-Ab1 deficient NOD mice carrying transgenes encoding humanized CD4 and HLA-DQ6 lack T and B cells and are free of autoimmune diabetes and cardiomyopathy, and do not develop thyroiditis.

This model is useful in adoptive transfer experiments and in studying MHC class II-based resistance and susceptibility in autoimmunity.

006022 NOD.Cg-Rag1tm1Mom H2-Ab1tm1Gru Tg(CD2-CD4,HLA-DQA1,HLA-DQB1)1Ell/EllJ
Cryopreserved - Ready for recovery
Rag1 and H2-Ab1 deficient NOD mice carrying transgenes coding for human CD2-CD4 and HLA-DQ8 lack T and B cells, and are diabetes free. Also, unlike the H2-Ab1 deficient, transgenic CD4, HLA-DQ8 mice (see Stock No. 006021), this strain does not develop cardiomyopathy.

This model is useful in adoptive transfer experiments and to understand the role of MHC class II in autoimmunity.

005686 NOD.Cg-Thy1a Tg(TcraCl4,TcrbCl4)1Shrm/ShrmJ
Cryopreserved - Ready for recovery
Transgenic mice, commonly referred to as NOD.clone-4 TCR, are viable, fertile, normal in size, normoglycemic and do not display any gross physical or behavioral abnormalities. The TCR expressed from this transgene is specific for influenza virus A/PR/8 hemagglutinin (HA) in the context of the MHC class I molecule H2-Kd. FACS analysis of pancreatic lymph node indicates CFSE treated NOD clone-4 T cells adoptively transferred into NOD.InsHA (Stock No. 005685) proliferate vigorously and there is a 2-3-fold increase in the percentage of dividing clone-4 TCR, CD8+ T cells when compared to BALB/cBy (Stock Nos. 005307 and 005533) or B10.D2 (Stock Nos. 005308 and 005534). HA specific reactivity not tolerance is observed.

This mouse is further modified with the Thy1a allele, rather than the alternate allele Thy1b present in C57BL/10, DBA/2, BALB/c and NOD/Lt mice. Thus, cell populations derived from these transgenic mice c .....

005685 NOD.Cg-Tg(Ins2-HA)165Bri/ShrmJ
Cryopreserved - Ready for recovery
Transgenic mice are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. The diabetes rate in transgenic females is similar to NOD females. FACS analysis using anti-HA antibodies indicates similar levels of HA expression on pancreatic beta cells as BALB-InsHA (Stock No. 005533). Tetramer (KdHA) binding and dose titration analysis indicate CD8+ T cells obtained from transgenic mice exhibit high avidity for HA. Irradiated transgenic females adoptively transferred with transgenic CTL's exhibit rapid diabetes onset, whereas irradiated, non-transgenic NOD females do not become diabetic indicating HA antigen specificity. This model is useful for studying CD8+ T cell peripheral tolerance deficiency (Kreuwel et al. 2001).
002380 NOD.Cg-Tg(Ins2-TAg)1Lt Prkdcscid/DvsJ
Cryopreserved - Ready for recovery
Homozygous NOD/Lt-TgN(RipTag)1Lt-Prkdcscid mice develop pancreatic beta cell adenomas. They are able to produce 2-3 litters before the insulin secreted from the adenoma makes them too hypoglycemic. Because Prkdcscid mice lack T-cells the adenomas from this strain are free of the autoimmune T-cells found in the adenomas of NOD/Lt-TgN(RipTag)1Lt mice.
008549 NOD.FVB-Tg(Itgax-DTR/EGFP)57Lan/JdkJ
Cryopreserved - Ready for recovery
Unmanipulated NOD congenic Itgax-DTR/EGFP (Cd11c-DTR) transgenic mice are viable, normal in size and develop spontaneous diabetes similar to NOD/ShiLtJ. All splenic CD8+ and CD8- DC express EGFP and are diphtheria toxin (DT) sensitive. Upon DT administration, mice harboring this transgene are transiently depleted of dendritic cell (DC) populations. Immunohistochemical and flow cytometric analysis reveals EGFP expression and DT-inducible depletion of CD11chigh DC in spleen, lymph node, lung, liver and lamina propria tissues, as well as the defined macrophage subpopulations of the alveolar, lamina propria, metallophillic and marginal zone. Rapid reduction of CD11c+ DC populations induced by intraperitoneal injection of DT persists for approximately 2 days, after which the cell population gradually recovers. While transient DC depletion was not associated with sign of illness or long-term defects, repeated DT inductio .....

Cryopreserved - Ready for recovery
Transgenic mice carrying the Ighmtm1Cgn allele are viable, fertile, and normal in size and restores the B220+ B-cells. The number of B-cells is reduced and the ratio of CD4 to CD8 is normal. Although only a fraction of the transgenic mice have an increased amount of insulitis, it is significantly more severe, especially in males. No diabetes was observed in NODCaj.Cg-Ighmtm1Cgn Tg(Igh-VB1-8/Igh-6)2Mjsk/FswJ mice by 50 weeks of age.

This model serves as a control for the membrane bound, non-secreted, NODCaj.Cg-Ighmtm1Cgn Tg(Igh-VB1-8/Igh-6m)1Mjsk/FswJ (Stock No. 005306).

005306 NODCaj.Cg-Ighmtm1Cgn Tg(Igh-VB1-8/Igh-6m)1Mjsk/FswJ

Transgenic mice carrying the Ighmtm1Cgn allele are viable, fertile, and normal in size and restores the B220+ B-cells to normal. The number of B-cells is normal and the ratio of CD4 to CD8 is normal. Although only a fraction of the transgenic mice have an increased amount of insulitis, it is more severe, especially in males. Diabetes incidence is partially restored in NODCaj.Cg-Ighmtm1Cgn Tg(Igh-VB1-8/Igh-6m)1Mjsk/Fsw with approximately, 11% females and 0% males becoming diabetic by 50 weeks of age compared to approximately 2% Ighmtm1Cgn female controls and 0% Ighmtm1Cgn male controls by 50 weeks of age or 90% female NOD controls and 70% male NOD controls by 30 weeks of age.

Derived from an unknown stock at the Rockefeller Institute, RF/J are commonly used in research in genetics, immunology, oncology and virology. This strain displays a high cancer incidence including leukemia (reportedly between 40 and 66%) and reticulum cell sarcomas (approximately 50%). Mice also have a high incidence of spontaneous glomerular hyalinisation and glomerulosclerosis developing between eight and twenty months.
003899 STOCK Cd44tm1Hbg/J
Cryopreserved - Ready for recovery
Mice that are homozygous for the targeted mutation are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. No gene product (mRNA or protein) is detected. Although lymphocyte development appears unremarkable, irregularities are observed in lymphocyte trafficking. Tail-injected lymphocytes derived from null animals exhibit an impaired ability to traffic to peripheral lymph nodes, and to a much greater degree, the thymus. Transcription and translation of the targeted allele subsequently lead to the synthesis of the lacZ protein under control of the 5' regulatory elements of the endogenous locus in all cells and tissues normally expressing one or several of the CD44 isoforms.
003118 STOCK Ces1ce Foxn1nu/J
Cryopreserved - Ready for recovery
Mice homozygous for Ces1ce are viable and fertile and exhibit no apparent defect.

Ces1ce was discovered in a screen of progeny of triethylenemelamine (TEM) treated male mice for mutations at specific loci, but appears to have pre-existed in the male. The screen employed analysis of blood and kidney homogenates by "standard starch gel electrophoresis techniques" and focused on enzymes known to differ in electrophoretic mobility between the parental strains (DBA/2J and C57BL/6J). Ces1ce was initially thought to be a null allele, but characterization of homozygous F2 mice demonstrated presence of a faint band migrating between those of the parental strains, which was not perceived in the presence of either parental band. Thus, Ces1ce was shown to be a hypomorphic electrophoretic variant (Soares 1979).

007580 STOCK Cyp1a2/Cyp1a1tm2Dwn Tg(CYP1A1,CYP1A2)1Dwn/J
Cryopreserved - Ready for recovery
Mice homozygous for the Cyp1a2/Cyp1a1(-) targeted allele and carrying the hCYP1A1_1A2 transgene are viable and fertile with normal lifespan. As the Cyp1a2/Cyp1a1(-) targeted allele lacks the coding regions of both Cyp1a1 and Cyp1a2 genes, no expression of either gene transcript or protein is observed in liver or small intestine by quantitative RT-PCR or Western blot, respectively. Transgene expression of the orthologous human genes is observed in the same tissues. While oral benzo[alpha]pyrene (BaP) treatment of Cyp1a2/Cyp1a1(-/-) mutant mice leads to BaP-induced immunosuppression and sickness, the presence of the human CYP1A orthologs in these mice minimizes/prevents such toxicity. These humanized hCYP1A1_1A2_Cyp1a2/Cyp1a1(-/-) mice may useful in drug or carcinogen metabolism research; specifically as a model for human risk assessment studies involving drug or environmental toxicants that may be substrates for cytochrome P450 family mem .....

009063 STOCK Ednrbtm1Nrd/J
Cryopreserved - Ready for recovery
Mice heterozygous for this Ednrbflex3 allele are viable and fertile, with a loxP-flanked neo cassette upstream of exon 3, as well as a loxP site downstream of exon 3 of the Ednrb (endothelin receptor type B or ET-B receptor) gene. When bred to mice that express Cre recombinase, the resulting offspring can have one of three resulting genotypes in the cre-expressing tissue(s); only the neo selection cassette deleted, only exon 3 deleted, or both the neo selection cassette and exon 3 deleted. The two latter genotypes are expected to result in a frameshifted transcript that is reported to confer the null phenotype. These mutant mice may be useful in generating conditional mutations for studying the role of Ednrb in development of melanocytes, development of neurons and glia of the enteric nervous system, neural crest-derived cells, mesenchymal-derived smooth muscle cells, vasodilation, mitogen signaling and cancer, and human Hirschsprung's dis .....

007681 STOCK Epb4.1l3tm1Jkis/J
Cryopreserved - Ready for recovery
Mice homozygous for this 4.1B/Dal-1 targeted allele are viable, fertile, and age normally with no spontaneous tumor formation. Lung, brain, breast, and prostate tissues from homozygotes show no protein expression from the mutant locus. Although 4.1B-deficient females do not form tumors of the mammary gland, a significant increase in mammary epithelial cell proliferation during pregnancy is observed. When these 4.1B-deficient mice are bred with TRAMP transgenic mice (see Sock No. 003135), the resulting double mutant offspring exhibit increased susceptibility for developing aggressive prostate carcinomas and enhanced tumor malignancy associated with reduced apoptosis. Because 4.1B expression is frequently downregulated in human clinical prostate cancer (and a spectrum of other tumor types), these 4.1B mutant mice may be useful in studying the role of 4.1B as a negative regulator of cancer progression to metastatic disease.

Cryopreserved - Ready for recovery
Mice heterozygous for both targeted mutations (R26-rtTA and Col1a1::tetO-3F2A) are viable and fertile (mice homozygous for both targeted mutations were not generated by the donating investigator but are expected to be viable and fertile as well). These double mutant R26rtTA;Col1a13F2A mice have widespread expression of the optimized form of reverse tetracycline-controlled transactivator (rtTA-M2) protein directed to multiple tissues by the Gt(ROSA)26Sor promoter. In the absence of the tetracycline analog doxycycline (dox), expression of the dox-inducible 3F2A cassette from the Col1a1 locus is not detected. Following dox administration, this single-gene transgenic mouse strain expresses the polycistronic 3F2A cassette (three mouse reprogramming genes Oct4 [Pou5f1], Klf4, and c-Myc [Myc]). While somatic expression of these three reprogramming factors alone does not allow the generation of induced pluripotent stem cells (iPSCs), ad .....

Cryopreserved - Ready for recovery
Mice homozygous for the p85β "knockout" allele are viable and fertile, with no protein expression in liver or muscle from the targeted gene. Phosphoinositide 3-kinases (PI3K) activity associated with p85β is abolished in liver and muscle from homozygous mice. p85β-null mice exhibit significantly lower glucose levels (both fasting and fed states), decreased plasma insulin concentrations (fed state), and significantly improved glucose-lowering effect after intraperitoneal insulin injection compared to wildtype mice. PKB/AKT activity is significantly upregulated in muscle (but not liver) from p85β-deficient mice. These mutant mice may be useful for studying class IA phosphoinositide 3-kinases (PI3Ks) in cell growth, cell proliferation cell survival signaling, insulin signaling and tumor angiogenesis, as well as genomic aberrations that promote tumorigenesis/cancer through upregulation of the PI3K/AKT signaling axis.

Cryopreserved - Ready for recovery
Mice homozygous for the severe combined immune deficiency spontaneous mutation (Prkdcscid, commonly referred to as scid) are characterized by an absence of functional T cells and B cells, lymphopenia, hypogammaglobulinemia, and a normal hematopoietic microenvironment. Normal antigen-presenting cell, myeloid and NK cell functions are strain dependent. scid mice carry a DNA repair defect and a defect in the rearrangement of genes that code for antigen-specific receptors on lymphocytes. Most homozygotes have no detectable IgM, IgG1, IgG2a, IgG2b, IgG3, or IgA. Thymus, lymph nodes, and splenic follicles are virtually devoid of lymphocytes. scid mice accept allogeneic and xenogeneic grafts making them an ideal model for cell transfer experiments. Some scid mice will spontaneously develop partial immune reactivity. scid mice that have serum Ig levels greater than 1 ug/ml are considered "leaky." scid leakiness is highly strain depen .....

Mice that are heterozygous for the targeted mutation are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. Mouse embryo fibroblasts (MEFs) cannot be derived from homozygous embryos. Homozygous null mice have an embryonic lethal phenotype, failing to develop somewhere between embryonic days 9.5 and 12.5. Homozygous mutant embryonic day 8.5 and 9.5 embryos exhibit increased apoptosis and reduced cellular proliferation. This mutant mouse strain may be useful in studies of development, DNA damage and repair, and genomic stability.

Mice homozygous for both the targeted mutation and the transgene are viable and fertile. The transgene beta-galactosidase is well expressed, reflects endogenous Tek/Tie2 activity, and is specific to the vascular endothelium. Mice homozygous for the Rag1 mutation are immunodeficient as they lack mature B and T lymphocytes. This double mutant mouse may be useful in studies of cancer, tumor-related angiogenesis, and as a recipient of xenografted tumors.
006083 STOCK Sfpi1tm1.3Dgt/J
Cryopreserved - Ready for recovery
Mice homozygous for this targeted deletion are viable and fertile as young animals. Mice on this stock (predominantly 129Sv) background often die between 3-8 months of age of a rapidly developing T cell lymphoma (64% penetrance) or between 6-12 months of acute myeloid lymphoma (AML) (29% penetrance). Homozygotes (termed PU.1 knockdown or UREdelta) have an 80% reduction of endogneous gene expression. This is associated with an accumulation of hematopoietic stem cell precursor cells and neutrophils in bone marrow and spleen. Bone marrow cells from homozygous mice have abnormal responses to myeloid cytokines, and malignant transformation is associated with clonal chromosomal abnormalities. Homozygous mice have abnormal B- and T-cell populations and lineage commitment. These mice may be useful in studing T cell lymphoma, AML and other cancers, transcription factors, and development of multiple cell lineages.

Of note, the latency and penetrance of disease is slightly different from those .....

Mice hemizygous for this "Z/AP-AML1-ETO" transgene (coding for the translocation t(8;21) present in 15% of acute myeloid leukemias (AML)) are viable and fertile. Homozygotes die in utero presumably due to high lacZ expression. Prior to cre-mediated excision of the "floxed" STOP sequence, expression of lacZ is observed in all tissues including bone marrow progenitor cells. When bred to Cre recombinase expressing mice, the STOP sequence (and beta-geo) is removed in the resulting offspring, allowing transcription/co-expression of both the human AML1-ETO fusion protein and placental alkaline phosphatase (ALPP or PLAP) to proceed in the Cre recombinase expressing cells. While pan expression of AML1-ETO leads to embryonic lethality (E7.5), hematopoietic and endothelial expression leads to malignancy in B- and T- lymphoid cells and secondary mutations that closely resemble the association of AML1-ETO with acute myeloid leukemia in humans.

Mice hemizygous for this Cre-conditional TEL-AML1 (or iZ/EG-TEL-AML1) transgene are viable and fertile. Homozygotes die in utero, presumably due to high lacZ expression. Prior to Cre-mediated excision of the "floxed" STOP sequence, high expression of lacZ is observed in cells and tissues. When bred to Cre recombinase transgenic mice, the STOP sequence (and beta-geo) is removed in the resulting offspring, allowing transcription/co-expression of both the human TEL-AML1 fusion protein and EGFP in all cre-expressing cells. TEL-AML1 transcripts are not observed in adult organ tissues prior to excision of the floxed sequences. Following Cre-mediated deletion of the STOP sequence (by B6.Cg-Tg(Tek-cre)12Flv/J, Stock No. 004128), Western blot analysis reveals that EGFP levels are well correlated with TEL-AML1 transcript levels.

Double homozygous mutant mice produce no mature T, B, or NK cells. They have no CD3+ or T cell receptor (TCR) alpha-beta positive cells. The thymus of the mutant mice contains 15 to 130 times fewer cells than heterozygous or wildtype siblings. The thymocytes are CD8-CD4- and most are IL2 receptor positive. Neither the spleen nor bone marrow contain any IgM or IgD staining cells, indicating an absence of mature B cells. These and other data suggest that B cell and T cell development has been arrested at an early stage.

These mice express a mutant form of human butyrylcholinesterase (BCHE or BChE), harboring a single amino acid change at codon 117 (His for Gly), under the control of the ROSA26 promoter. This mutation has the unusual ability to hydrolyze organophosphorus toxicants (OP), as well as acetylcholine and is resistant to inhibition by OP. All tested tissues show G117H BChE enzymatic activity. In the founder mice and immediate offspring, plasma concentrations of the mutant protein are approximately 25% of endogenous wildtype mouse BChe. No reported abnormalities result from BChE overexpression in homozygous mutant mice. Transgenic mice injected with the OP echothiophate are protected from the severe toxicity and lethality observed in wildtype controls. This is the first transgenic mouse strain that expresses human BChE as well as the first mammal with hereditary OP resistance. These G117H BChE transgenic mice may be useful for biodefe .....

When bred with another mouse expressing reverse tetracycline-controlled transactivator protein (rtTA) or tetracycline-controlled transactivator protein (tTA), tissue diphtheria toxin A expression can be regulated with the tetracycline analog doxycycline (dox) in the resulting double mutant offspring. These tet-DTA mice may be useful in generating bi-transgenic mutant mice for the reversible, inducible deletion of specific groups of cells.

For example, when bred to a strain expressing tTA in cardiac myocytes (see Stock No. 003170 for example), this mutant mouse strain may be useful in studies of human cardiomyopathies.

SWXJ9 female mice develop ovarian granulosa cell carcinomas with an incidence of approximately 12% and a latency of 4-6 weeks. Tumor incidence can be increased to approximately 40% by treatment with dehydroepiandrosterone (DHEA) or testosterone immediately after weaning. Treatment with estradiol during this period completely suppresses tumorigenesis. Neoplasias are first observed as hemorrhagic follicles in which the antrum is blood-filled and lined with irregular masses of proliferating granulosa cells. By 6-10 weeks of age, the primary tumor encompasses the entire ovary. Metastases to lung, renal node, and liver are common by 6 to 9 months of age, with other sites occasionally affected. Susceptibility to granulosa cell carcinomas is controlled by a small number of genes, including a major susceptibility locus on Chromosome 4 and a major modifier locus on the X chromosome.
017293 B6.129S1(Cg)-Eomestm1.1Bflu/J
Under Development - Now Accepting Orders
These Eomesfl/fl mutant mice possess loxP sites flanking exon 2 of the eomesodermin homolog (Eomes) gene. Mice that are homozygous for this allele are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. EOMES is a member of the T-box family of transcription factors which is expressed in CD8+ T cells, CD4+ T cells, natural killer (NK) cells, and embryonic forebrain floorplate and migrating neuroblasts. EOMES is involved in embryonic development of the central nervous system and mesoderm, and plays a key role in CD44 expression, CD8+ T cell effector function and anticancer responses. When bred to mice that express tissue-specific Cre recombinase, resulting offspring will have exon 2 deleted in the cre-expressing tissues. This strain may be useful for studying T cell-mediated immune response, immune surveillance and editing, and embryonic development.

Under Development - Now Accepting Orders
The TEL-AML1 (ETV6-RUNX1, t12;21) translocation/fusion protein is a feature in approximately 25% of childhood Acute Lymphoblastic Leukemia (ALL) cases. This leukemia type is initiated in utero, and fusion protein is detectable in cord blood, but overt symptoms don't appear until the third or fourth year of life.

This mutant mouse strain carries a conditional gene fusion created by targeting truncated human RUNX1 (runt related transcription factor 1) cDNA preceded by a loxP-flanked STOP to the first base pair of exon 6 of the mouse Etv6 (ets variant gene 6 (TEL oncogene)) gene. As in leukemic cells, the Etv6 promoter drives expression. After cell or tissue-specific cre-mediated excision of the floxed stop cassette, normal splicing generates an mRNA encoding a hybrid protein with a breakpoint identical to that found in translocation t(12;21). Heterozygous floxed STOP mice are viable, but homozygotes are embryonic lethal due to a loss of Etv6 expressi .....

017581 B6.129S4-Ifngtm3(EYFP)Lky/J
Under Development - Now Accepting Orders
The "interferon-gamma reporter with endogenous polyA transcript" (GREAT) allele has an IRES-eYFP reporter cassette inserted between the translational stop codon and 3' UTR/polyA tail of the interferon gamma (Ifng) gene. Thus, the bicistronic IFNγ-IRES-eYFP mRNA is under control of the endogenous IFNγ promoter/enhancer regions with proper regulation defined by the endogenous 3' UTR and polyA tail. Expression of eYFP is observed by FACS/immunofluorescence microscopy in Ifng-expressing cell types; including innate immune responding cells (natural killer [NK] cells, natural killer T [NKT] cells) and cytotoxic T lymphocyte (CTL) effector cells of the adaptive immune response (CD4+ and CD8+T cells).

Of note, the donating investigator reports that these GREAT mice are a more useful tool than their IFNγ-IRES-YFP-BGHpolyA knockin (YETI) mice. Because the YETI allele has a bovine growth hormone polyA .....

014588 B6.Cg-Gt(ROSA)26Sortm1(rtTA*M2)Jae Col1A1tm6(tetO-MSI2)Jae/J
Under Development - Now Accepting Orders
These Coll1a1-TetO-MSI2 (Coll-TetO-MSI2) double mutant mice carry two targeted mutations: (1) an optimized form of reverse tetracycline controlled transactivator (rtTA*M2) in the Gt(ROSA)26Sor locus and (2) a tetracycline responsive element (tetO or TRE)-controlled human MSI2 (musashi homolog 2) gene in the Col1a1 locus. MSI2 plays a role in regulation of hematopoiesis. Aberrant MSI2 expression is associated with aggressive myeloid leukemia and poor prognosis in blast crisis chronic myelogenous leukemia. Doxycycline administration induces widespread overexpression of human MSI2 (musashi homolog 2), resulting in expansion of hematopoietic stem and progenitor cells. While mutant mice treated continuously with doxycycline for 1 year exhibit increased spleen and liver weights, and a reduction in MSI2 induction over time, they do not develop leukemia. Mice that are homozygous for the targeted mutations and untreated with doxycycline a .....

Under Development - Now Accepting Orders
Mice homozygous for both polymorphic alleles (p38αβY323F) are viable, fertile and of normal size and weight. Each mutation introduces a tyrosine to phenylalanine at codon 323 (Y323F) within exon 11 of their respective locus; this prevents phosphorylation of residue 323 for each protein. While each polymorphism should have no direct affect on canonical MAPK cascade-induced p38 activation, the T cell receptor (TCR)-mediated alternative activation pathway of p38 activation is abolished in homozygous p38αβY323F mice. Accordingly, activation-induced p38 phosphorylation in p38αβY323F T cells is reduced relative to the respective contribution of each isoform to total T cell p38 activity (p38βY323F > p38αY323F > p38αβY323F). This failure to activate both the p38α and p38β isoforms in T cells via TCR engagement results in impaired T cell proliferation compare .....

017593 B6;129S-Sox2tm1(cre/ERT2)Hoch/J
Under Development - Now Accepting Orders
These Sox2-CreER knockin mice have the SRY-box containing gene 2 (Sox2) open reading frame replaced with a CreERT2 fusion gene. Sox2 is a widespread marker of pluripotent and many adult stem/progenitor cell types. Heterozygous mice are viable and fertile, while homozygous mice exhibit embryonic lethality. Following tamoxifen administration, Cre-ERT2 activity is observed in adult epithelial tissues; including testes, forestomach, glandular stomach, anus, cervix, esophagus, and lens, as well as glands associated with oral cavity, trachea, and cervix. When these mice are bred with mice containing loxP-flanked sequence, tamoxifen-inducible, Cre-mediated recombination will result in deletion of the floxed sequences in the cre-expressing cells of the offspring. Cre-ERT2 activity is also detected in blastocysts, neural progenitor cells, and embryonic stem cell cultures following tamoxifen administration. These mice may be useful for stud .....

016901 B6N.129S-Txniptm1.1Rlee/J
Under Development - Now Accepting Orders
Mice homozygous for a systemic knockout of the Txnip (thioredoxin interacting protein) gene are viable, fertile, and born at predicted Mendelian frequencies. No TXNIP protein is synthesized. Fasting blood glucose levels indicate hypoglycemia without hyperinsulinemia. Homozygous mice placed on a high-fat diet for 4 weeks show significant increases in adipogenesis and insulin sensitivity as compared to wildtype controls.
012873 C.DDD-plt/NknoJ
Under Development - Now Accepting Orders
Homozygous BALB/c-plt mice are viable and fertile, harboring the spontaneous plt (or "paucity of lymph node T cells") deletion of both the Ccl19 and Ccl21a loci on chromosome 4. Lack of expression of these two CCR7 receptor ligands in the secondary lymphoid organs results in abnormal leukocyte migration and impaired immune response. Specifically, homozygous mice have disrupted trafficking/homing of T cells and dendritic cells to lymphoid tissues. No reported abnormalities in B cell distribution/cellularity are reported for homozygous mice. Homozygous mice exhibit mature single-positive thymocyte arrest in the thymic cortex that results in defective formation of the medullary region of the thymus. Thymic export of T cells in these mice is compromised during the neonatal period but not in adulthood. While CCL21 expression is absent in lymphoid organs because of the Ccl21a deletion, CCL21 expression in non-lymphoid organs is observed because the upstre .....

014547 FVB/N-Tg(tetO-Fasl)BDepa/J
Under Development - Now Accepting Orders
Mice hemizygous for the (tetOp)7-FasL transgene (TetOp-FasL transgenic mice) are viable and fertile with no reported phenotypic abnormalities. The (tetOp)7-FasL transgene has the Tet response element (TRE or tetO) upstream of a murine Fas ligand (FasL) coding sequence. When bred with other mice expressing tetracycline-controlled transactivator protein (tTA) or reverse tetracycline-controlled transactivator protein (rtTA), FasL overexpression in the resulting double mutant offspring can be regulated with tetracycline or its analog doxycycline (dox). FasL overexpression leads to Fas/FasL receptor-mediated death-signaling pathway activation and results in cell apoptosis. The donating investigator reports that transgenic mice from founder line B (TetOp-FasL transgenic line B) exhibit very high FasL overexpression levels in the presence of rtTA and 0.01 mg/ml Dox (low FasL levels are achievable by titrating Dox even lower). The donating investigator rep .....

017637 NOD.Cg-Prkdcscid Il2rgtm1Wjl H2-Ab1tm1Gru Tg(HLA-DRB1)31Dmz/SzJ
Under Development - Now Accepting Orders
These NSG-Abo DR4 mice lack expression of the murine Prkdc gene, the X-linked Il2rg gene, and MHC class II, but express the human leukocyte antigen DR4 gene. When maintained as homozygous for all three targeting events, and carrying one copy of the transgene, these mice are viable and fertile. Unlike in the NOD.Cg-Prkdcscid Il2rgtm1Wjl/SzJ (NSG) mice (Stock No. 005557), the expression of HLA-DR4 in these mice leads to the development of allo-graft-versus-host disease (GVHD) after engraftment of human DR4-negative CD4+ T cells. These mice may be useful for targeting human CD4+ T cells in transplantation studies in the absence of xeno-GVHD.
014093 STOCK Tg(tetO-CHRM3*)1Blr/J
Under Development - Now Accepting Orders
Hemizygous TRE-hM3Dq transgenic mice are viable and fertile, with no reported phenotypic abnormalities. The TRE-hM3Dq transgene has a modified Tet response element (TRE or tetO) upstream of the mutant G protein-coupled receptor, hM3Dq (a human muscarinic 3 receptor with two amino acid substitutions (Y149C3.33/A239G5.46) that abolish receptor affinity for the native ligand, acetylcholine (ACh), but allow receptor binding and subsequent activation by the small pharmacologically inert molecule clozapine-N-oxide (CNO)). When bred with another mouse expressing tetracycline-controlled transactivator protein (tTA) or reverse tetracycline-controlled transactivator protein (rtTA), hM3Dq expression in the resulting double mutant offspring can be regulated with tetracycline or its analog doxycycline (dox). As designed, TRE-hM3Dq transgenic mice have no reported levels of hM3Dq activity in tTA(+dox) or rtTA(-dox) cell types. In TRE-hM3Dq transgenic tTA(-dox) .....

016919B6.Cg-Rag1tm1Mom Fcgrttm1Dcr Tg(CAG-FCGRT)276Dcr/DcrJ
Awaiting Transfer from the Donor
These Rag1-/- FcRn-/- hFcRn (276) Tg mice express a human FCGRT molecule in lieu of the endogenous mouse Fcgrt. The absence of Rag1 makes the mice immunodeficient and therefore permits the engraftment of tissues and cell lines, making these mice well-suited for applications associated with the study of the pharmacokinetics and efficacy of therapeutic monoclonal antibody and FC fusion protein treatment. Further, these mice are suitable for the evaluation of immunogenic compounds.
016868B6.Cg-Ssttm1.2(tTA2)Hze/J

SST-tTA2-D mice have synthetic modified tetracycline-regulated transactivator (tTA2S) gene expression directed to Sst-expressing cells by the endogenous promoter/enhancer elements of the somatostatin locus. These SST-tTA2-D mice are a Tet-Off tool that allows dox-conditional expression of genes in Sst-expressing cells/tissues.
017722B6.Cg-Tg(Tal1-tTA)19Dgt/J
Awaiting Transfer from the Donor
Hemizygotes are viable, fertile, normal in size, and do not display any behavioral abnormalities. Hemizygotes express tetracycline-controlled transactivator protein (tTA) in bone marrow hematopoietic stem cells (HSC) and in common myeloid progenitors (CMP)). tTA activity also is detected in lung. Little to no tTA activity is detected in thymus, lymph node, intestine or spleen. When bred to other transgenic mice carrying a gene of interest coupled to a tetracycline-responsive promoter element (TRE; tetO), expression of the target gene in the bitransgenic offspring can be induced by withdrawal of tetracycline or doxycycline. This strain represents an effective tool for generating bitrangenic animals to study inducible gene expression in blood stem and progenitor cells.

In an attempt to offer alleles on well-characterized or multiple genetic backgrounds, alleles are frequently moved to a genetic background different from that on which an allele was first characterized. This is the cas .....

012346B6;129-Terf2iptm1.1Tdl/J
Awaiting Transfer from the Donor
These Rap1F mice harbor loxP sites flanking exon 2 (encoding the TRF2 binding domain) of the mouse Rap1 locus (also called mRap1, TRF2-interacting factor, Terf2ip, or telomeric repeat binding factor 2 interacting protein). Telomeres serve a dual role in protecting the chromosome ends from degradation/repair activities and in intracellular signaling for regulating cell proliferation. Mammalian telomeres are formed by tandem TTAGGG sequence repeats bound by a specialized complex of six telomere-associated proteins called the shelterin complex. As Rap1 is one of the components of shelterin, these Rap1F mutant mice may be useful in generating conditional mutations for studying the shelterin complex of telomeres, telomere maintenance, chromosomal stability, cancer, and aging.

These GREAT mice are a fluorescent reporter strain for studying innate immunity/adaptive immunity against viral and intracellular bacterial infections, for studying anti-tumor biology, as well for studying aberrant IFN-γ expression associated with autoinflammatory/autoimmune diseases.
017830NOD.Cg-Prkdcscid Il2rgtm1Wjl Tg(PGK1-KITLG*220)441Daw/SzJ
Awaiting Transfer from the Donor
These mice express a 220 amino acid isoform of the human membrane-bound stem cell factor (hSCF or KITLG), and carry the severe combined immunodeficiency allele (scid) of the protein kinase, DNA activated, catalytic polypeptide (Prkdc) gene and the Il2rgtm1Wjl targeted mutation of the interleukin 2 receptor, gamma chain gene. Newborn NSG-Tg(hu-mSCF) mice engraft human hematopoietic stem cells without pre-conditioning irradiation treatment and develop mature functional humanized immune systems, capable of rejecting histoincompatible human skin grafts. Differentiated c-Kit+ human mast cells are detected in bone marrow, spleen, and mucosal lung, gastric, and intestinal tissues of engrafted mutant mice.

These NSG-Tg(hu-mSCF) mice provide a supportive microenvironment that is conducive to engraftment of human hematopoietic stem cells and would be useful in studies of human mast cell development and allergic responses.

002318C.Cg-Tg(BCL2)22Wehi/J
On Hold
Expression of the human BCL2 transgene is restricted to B cell lineage (no T cell expression) in which it enhances cell survival. Hemizygotes show increased numbers of B lymphocytes, Ig-secreting cells and serum Ig, as well as a heightened and prolonged antibody response to immunization. This phenotype is somewhat greater on the BALB/c than on the C57BL/6 background. Hemizygotes on a mixed B6,SJL background (but not on the BALB/c background) develop autoimmune disease characterized by immune complex glomerulonephritis, anti-nuclear antibodies, lymphadenopathy and myocardial infarction. These mice serve as a robust source for the production of B cells and antibodies. Although mice bearing this allele exhibit a mild increase in spontaneous lymphoma and plasmacytoma occurrence (<10% to 18 months) on a (C57BL/6 x SJL)F2 background, on the BALB/c and C57BL/6 backgrounds tumor incidence is insignificant. When this transgene is crossed with an Emu-myc transgene bearing strain (Stock .....
