| 002052 | B6.129P2-Apoetm1Unc/J | Level 1 |
| Mice homozygous for the Apoetm1Unc mutation show a marked increase in total plasma cholesterol levels that are unaffected by age or sex. Fatty streaks in the proximal aorta are found at 3 months of age. The lesions increase with age and progress to lesions with less lipid but more elongated cells, typical of a more advanced stage of pre-atherosclerotic lesion. Moderately increased triglyceride levels have been reported in mice with this mutation on a mixed C57BL/6 x 129 genetic background. Aged APOE deficient mice (>17 months) have been shown to develop xanthomatous lesions in the brain consisting mostly of crystalline cholesterol clefts, lipid globules, and foam cells. Smaller xanthomas were seen in the choroid plexus and ventral fornix. Recent studies indicate that APOE deficient mice have altered responses to stress, impaired spatial learning and memory, altered long term potentiation, and synaptic damage. | ||
| 000648 | AKR/J | Level 2 |
| Originally inbred at the Rockefeller Institute, AKR mice are widely used in cancer research for their high leukemia incidence (60-90%) and in immunology as a source of the Thy1.1 (theta AKR) antigen. AKR/J mice are viremic from birth, and express the ecotropic retrovirus AKV in all tissues. The hair interior defect (hid) mutation, a strain characteristic of AKR mice, causes alterations in hair development that is only evident microscopically. Adrenocortical lipid depletion (ald) in AKR mice is caused by a mutation in sterol O-acyltransferase 1 (Soat1), and leads to a truncated SOAT1 protein. AKR/J mice are relatively resistant to aortic lesion formation on a semi-synthetic high fat diet and are hyporesponsive to diets containing high levels of fat and cholesterol. | ||
| 002207 | B6.129S7-Ldlrtm1Her/J | Level 2 |
| Mice homozygous for the Ldlrtm1Her mutation have an elevated serum cholesterol level of 200-400 mg/dl and they have very high levels (>2,000 mg/dl) when fed a high fat diet. Normal serum cholesterol in the mouse is 80-100 mg/dl. | ||
| 000629 | C57BL/6J-Lystbg-J/J | Level 4 |
| Mice homozygous for the beige-J spontaneous mutation (Lystbg-J) are identical to the original beige mutation (Lystbg). The phenotype closely resembles Chediak-Higashi disease in man and similar conditions in mink and cattle. Abnormal giant lysosomal granules occur in all tissues with granule-containing cells, including granulocytes, lymphocytes, cells of the liver, kidney, central nervous system, pancreas, and thyroid, and the ducts of most glands; in type II pneumocytes; in mast cells; and in retinal pigment epithelium. Granulocytes from beige homozygous mutant mice mice show defective chemotaxis and reduced bactericidal activity. Beige mice are more susceptible than controls to pneumonitis and to various viral, bacterial, and parasitic infections. Natural killer (NK) cells from beige mice exhibit decreased endogenous cytotoxic activity. Beige mice also have a defective cytotoxic T-cell and cytotoxic antibody response to allogeneic tumor cells.

| 002053 | B6.129P2-Apobtm1Unc/J | Repository- Live |
| The Apobtm1Unc targeted mutation produces a truncated form of the apolipoprotein B protein (APOB70)and no apoB100 that is similar to human familial hypobetalipoproteinemia condition. Expression of apoB48 is not altered. Homozygous mice show greatly reduced levels of plasma APOB, beta-lipoproteins, and total cholesterol. They also have reduced plasma triglyceride concentrations, fasting chylomicronemia, and reduced high density lipoprotein (HDL) cholesterol. Homozygotes also have a high incidence of exencephaly and hydrocephaly. Heterozygous mice show a slight increase over wildtype in the incidence of hydrocephaly. | ||
| 002778 | B6.129S2-Alox15tm1Fun/J | Repository- Live |
| 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. | ||
| 007682 | B6.129X1-Apobtm1.1Zc/J | Repository- Live |
| Mice homozygous for this apoB38.9 allele (apoB38.9/38.9) are viable with impaired fertility, bearing a premature stop codon at residue 1767 of the targeted gene. As a result, homozygous plasma shows a truncated apoB38.9 as the sole apoB protein. Plasma from heterozygous (apoB+/38.9) mice have reduced apoB100 and apoB48 compared to wildtype, with apoB38.9 representing 20% of total circulating apoB. This apoB38.9 truncation affects both apoB100 and apoB48 metabolism in mice, and mimics human Familial Hypobetalipoproteinemia (FHBL). Homozygous and, to a lesser extent, heterozygous mice exhibit symptoms of FHBL due to impaired lipoprotein export system/VLDL secretion, including elevated hepatic triglyceride (TG), cholesterol and free fatty acids (FFA), with decreased plasma TG and cholesterol. Because plasma and liver lipid profiles range from mild to severe in populations of heterozygous apoB38.9 mice on a mixed (C57BL/6J;129X1/SvJ) genetic background, apoB+/38

| 004265 | B6.129X1-Mpotm1Lus/J | Repository- Live |
| Mice that are homozygous null for the targeted gene are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. No Mpo gene product (mRNA or protein) is detected. Mutant mice exhibit total white blood cell counts and differentials similar to wildtype mice. Neutrophils and monocytes in periperhal blood and bone marrow have no endogenous peroxidase activity. Superoxide production levels in peritoneal exudate cells of mutant mice are similar to levels found in wildtypes mice. Hypochlorous acid production is undetectable in both isolated leukocytes and peritoneal exudate cells. Mutant mice display impaired fungicidal activity due to myeloperoxidase deficiency. When maintained under hyperlipidemic conditions, mutant mice develop atherosclerotic lesions 50% larger than those seen in control mice. | ||
| 006952 | B6.Cg-Akt2tm1.1Mbb Ldlrtm1Her/J | Repository- Live |
| Independently, homozygous Akt2 mutant mice develop insulin resistance and diabetes, while LDLR homozygotes are predisposed to atherosclerosis. Double mutant mice that are heterozygous for the Akt2 allele and homozygous for the LDLR mutation are viable and fertile. These double mutant mice may be useful in studies of diabetes, metabolism, hyperglycemia, and atherosclerosis. | ||
| 006580 | B6.Cg-Ins2Akita Ldlrtm1Her/J | Repository- Live |
| Mice homozygous for the Akita spontaneous mutation die postnatally, typically by 12 weeks of age. Independently, heterozygous Akita mutant mice are a model of insulin dependent diabetes mellitus (IDDM) with severe hyperglycemia (see the datasheet for Stock No. 003548 for additional information). LDLR-null homozygotes have elevated serum cholesterol levels (200-400 mg/dl) which can escalate to very high levels (> 2000 mg/dl) when the mice are fed a high fat diet. LDLR-deficient mice also are predisposed to develop atherosclerosis. These double mutant mice may be useful in studies of diabetes, metabolism, hyperglycemia, atherosclerosis, hypercholesterolemia, and diabetes-related macrovascular complications. | ||
| 006883 | B6.Cg-Ldlrtm1Her Sod2tm1Leb/J | Repository- Live |
| Independently, mice that are homozygous for this MnSOD mutation (Sod2tm1Leb) allele exhibit postnatal lethality and exhibit anemia, degeneration of neurons in the basal ganglia and brainstem, progressive motor disturbances, and myocardial injury. Individual LDLR homozygous mutants are predisposed to atherosclerosis. When mutant mice are homozygous for both alleles, they die in utero. Mice heterozygous for the Sod2 mutation and homozygous for the LDLR are viable and fertile. The mice may be useful in studies of diabetes, metabolism, hyperglycemia, atherosclerosis, and hypercholesterolemia, and oxidative stress. | ||
| 006877 | B6.Cg-Ldlrtm1Her Tg(H2-K-AKR1B1)1Tj/J | Repository- Live |
| Independently, mice hemizygous for this "huAR" transgene express human aldose reductase as a model for increased oxidative stress, while LDLR homozygotes are predisposed to atherosclerosis and hypercholesterolemia. The donating investigators report that the H2-Kd promoter functions on this H2-Kb genetic background without any loss of transgene expression. When mutant mice are hemizygous for the transgene and homozygous for the targeted allele, they may be useful in studies of diabetes, metabolism, atherosclerosis, hypercholesterolemia, and oxidative stress. | ||
| 006906 | B6.Cg-Lepob Ldlrtm1Her/J | Repository- Live |
| Independently, the C57BL/6-Lepob homozygotes (Stock No. 000632) model the increasingly prevalent metabolic disorder seen in humans (hyperglycemia, hyperinsulinemia, and hyperlipidemia), while LDLR-deficient mice (Stock No. 002207) are predisposed to atherosclerosis. When mutant mice are homozygous for both mutant alleles, they exhibit exacerbated hyperlipidemia and extensive atherosclerotic lesions in the aorta. The mice may be useful in studies of diabetes, metabolism, hyperglycemia, atherosclerosis, and hypercholesterolemia. | ||
| 004633 | B6.Cg-Tg(GFAP-APOE*3)37Hol Apoetm1Unc/J | Repository- Live |
| These transgenic mice express the human apolipoprotein E3 isoform (APOE3) under the direction of the human glial fibrillary acidic protein (GFAP) promoter and do not express endogenous mouse apolipoprotein E (APOE). The transgenic isoform expression pattern follows the endogenous mouse APOE and GFAP expression patterns in the brain. Human APOE3 is immunodetectable in glia and neuropil in developing and adult mutant mice. Cultured astrocytes from transgenic mice secrete APOE3 in lipoproteins that are similar in size to high-density (HDL) plasma lipoproteins. Detergent-soluble APOE3 protein levels in hemizygous mice forebrain tissue and in adult human cortex tissue are similar. Mice that are hemizygous or homozygous for the transgenic insert and homozygous for the targeted allele are viable, normal in size and do not display any gross physical or behavioral abnormalities. This mutant mouse strain represents a model that may be useful in studies examining the function of APOE3 in t

| 003263 | B6;129S2-Cdkn1atm1Tyj/J | Repository- Live |
| Homozygotes are viable and fertile. p21, the product of the Cdkn1a gene, belongs to a family of regulators, known as cyclin-dependent kinase inhibitors, which modulate progression through the cell cycle. Following serum restimulation, expression of p21 is superinducible by cycloheximide in wild-type but not in p53-deficient cells. p53 appears to play a critical role in p21 induction following DNA damage. p21 can be regulated independently of p53 during normal tissue development, following serum stimulation, and during cellular differentiation. | ||
| 006258 | B6;129S4-Apoa2tm1Bres/J | Repository- Live |
| Mice homozygous for this targeted mutation are viable and fertile. Homozygous mice have no detectable transcripts in liver tissues and the high density lipoprotein (HDL) particle size is reduced. Homozygotes have decreased plasma levels of HDL cholesterol and free fatty acids in both fed and fasted states. In addition, the plasma concentration of fasting glucose and insulin is decreased. These mice may be useful in studies of lipid metabolism, atherosclerosis, heart disease, insulin resistance and diabetes. | ||
| 006404 | B6;129S4-Apoa4tm1Bres/J | Repository- Live |
| Mice homozygous for this targeted mutation are viable and fertile with no protein detectable in plasma, liver, or intestinal tissues. Homozygotes have decreased plasma levels of cholesterol, free fatty acids, and high density (HDL) and very low density lipoprotein (VLDL). These mice may be useful in studies of lipid metabolism, atherosclerosis, heart disease, appetite regulation, intestinal lipid absorption, or inflammatory bowel disease. | ||
| 005993 | B6;129S6-Pcsk9tm1Jdh/J | Repository- Live |
| Homozygous mice are viable and fertile with no behavioral abnormalities. No expression of the endogenous RNA or protein is observed in liver. Homozygotes have reduced plasma cholesterol levels; apolipoprotein B (apoB)-containing low-density liproprotein (LDL) is nearly undetectable and apolipoprotein E (apoE)-containing high density liproprotein (HDL) levels are reduced 30%. Homozygotes show increased hepatic LDL-receptor (LDLR) protein (but not RNA) expression. Homogygous mice also have accelerated clearance of circulating cholesterol. Lovastatin addition to the diet of homozygous mice results in further increased hepatic LDLR and LDL clearance from the blood. Heterozygous mice have intermediate plasma cholesterol and LDL clearance. This mouse may be useful in studies of lipid homeostasis, cholesterol metabolism, apolipoprotein function, and statin treatment for hypercholesterolemia. | ||
| 006208 | B6;129S6-Pdzk1tm1Dls/J | Repository- Live |
| Mice homozygous for this targeted mutation are viable and fertile. Liver tissue from homozygous mutant mice lacks endogenous protein expression. Homozygotes, but not heterozygotes, have significantly decreased (~85-95%) hepatic high density lipoprotein (HDL) receptor scavenger receptor B-I (SR-BI) levels. This decrease is further exacerbated following diet supplementation with the PPAR-alpha activator fenofibrate. These mice may be useful in studies of cardiovascular health and atherosclerosis, lipid metabolism, SR-B1 regulation, kidney function, as well as kidney transporter (e.g. urate transporter) regulation and liver organic anion transport. | ||
| 002077 | B6;129S7-Ldlrtm1Her/J | Repository- Live |
| Mice homozygous for the Ldlrtm1Her mutation have an elevated serum cholesterol level of 200-400 mg/dl and they have very high levels (>2,000 mg/dl) when fed a high fat diet. Normal serum cholesterol in the mouse is 80-100 mg/dl. | ||
| 006907 | B6;CBA-Tg(APOC3)3707Bres/J | Repository- Live |
| Mice hemizygous for this "human apo CIII" transgene are viable and fertile. This high expressor founder line (3703) exhibits transgene expression primarily in the liver with some intestinal expression as well. Hemizygous mice have severe plasma hypertriglyceridemia and significantly increased plasma cholesterol. However, resistance to insulin-mediated glucose uptake or hyperinsulinemia are not observed. This high expressor human apo CIII transgenic strain may be useful in studying lipid metabolism, very low density lipoproteins (VLDL), hypertriglyceridemia, coronary heart disease, and/or atherosclerosis. | ||

| Mice homozygous for this apoB38.9 allele (apoB38.9/38.9) are viable with impaired fertility, bearing a premature stop codon at residue 1767 of the targeted gene. As a result, homozygous plasma shows a truncated apoB38.9 as the sole apoB protein. Plasma from heterozygous (apoB+/38.9) mice have reduced apoB100 and apoB48 compared to wild-type, with apoB38.9 representing 20% of total circulating apoB. This apoB38.9 truncation affects both apoB100 and apoB48 metabolism in mice, and mimics human Familial Hypobetalipoproteinemia (FHBL). Homozygous and, to a lesser extent, heterozygous mice exhibit symptoms of FHBL due to impaired lipoprotein export system/VLDL secretion, including elevated hepatic triglyceride (TG), cholesterol and free fatty acids (FFA), with decreased plasma TG and cholesterol. These BALB/cByJ-apoB38.9 mice are also heterozygous for the BALB/cByJ-derived SCAD deletion (Acadsdel-J). While BALB/cByJ inbred mice have elevated liver TG f

| Mice homozygous for the Apoetm1Unc and Ldlrtm1Hertargeted mutations on a normal chow diet show cholesterol levels corresponding to those seen in the Apoetm1Unc targeted mutant strain. The lipoprotein pattern in homozygous mice also resembles that seen in the Apoetm1Unc targeted mutant strain (VLDL & chylomicron remnants). The double targeted mice have a marked increase in both APOB48 and APOB100. In addition, APOAIV is increased. | ||
| 005681 | B6.129S-Lipgtm1Tq/J | Repository-Cryopreserved |
| Homozygous mice are viable and do not display any behavioral or histological defects. Although homozygotes are fertile, the donating investigator reports decreased fecundity. Northern blot analysis showed no endogenous gene expression in lung, liver, kidney, spleen, or aorta. Homozygotes have increased fasting plasma levels of total cholesterol, high-density lipoprotein (HDL) cholesterol, and phospholipids compared to wild type. Mutant mouse plasma apoA-I is increased while heparin-releasable phospholipase activity is impaired. Homozygous null mice have decreased arterial endothelium monocyte adhesion. This mutant can be used in studies of lipoprotein metabolism, atherosclerotic vascular disease, and other cholesterol-related studies. | ||
| 006142 | B6.129S4-Ppargtm1Rev/J | Repository-Cryopreserved |
| All mice homozygous for this targeted mutation die after gestational day 9.5 from severe placental defects and myocardial thinning. Heterozygotes are viable and fertile. White adipose tissue from heterozygous mice display approximately half the mRNA expression compared to wildtype. Tracer-determined glucose disposal rates and hepatic glucose production show that peripheral tissues and livers from heterozygotes are more sensitive to the effects of insulin than wildtype. This mutation eliminates both DNA-binding and ligand-binding functions of the endogenous gene, concomitantly generating a lacZ reporter that faithfully recapitulates the endogenous expression pattern. Heterozygous mice or homozygous embryo-derived cells may be useful in studies of embryo and placental development, diabetes, atherosclerosis, inflammation, and for beta-galactosidase reporter function of the endogenous gene. | ||
| 003322 | B6.129S4-Soat1tm1Far/J | Repository-Cryopreserved |
| Mice homozygous for the Soat1tm1 targeted mutation display tissue specific decreases in cholesterol esterification. Fibroblasts and adrenal membranes of homozygous mutant mice show diminished cholesterol esterification and markedly reduced cholesterol ester levels in adrenal glands and peritoneal macrophages. However, the livers of SOAT1-deficient mice contained substantial amounts of cholesterol esters and exhibited no reduction in cholesterol esterification activity. These findings support the presence of more than one form of esterification enzyme in mammals. A second sterol O-acyltransferase gene (Soat2), expressed in the liver and intestine, has subsequently been identified in mice and humans. | ||
| 007147 | B6.129S4-Soat1tm1Far/Pgn | Repository-Cryopreserved |
| Phenotypically similar to B6.129S4-Soat1tm1Far/J (003322), B6.129S4-Soat1tm1Far/Pgn has a reduced congenic interval making the closely linked Apoa2 gene of C57BL/6 rather than 129S4 origin. The donating investigator indicates that HDL levels exhibit a 24% increase on high fat diet in this strain in contrast to the 73% increase observed in the original strain. Triglyceride levels are unchanged. This strain may be useful in atherosclerosis research. | ||
| 003823 | B6.129S4-Ttpatm1Far/J | Repository-Cryopreserved |
| 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. | ||

| These transgenic mice express the human apolipoprotein E2 isoform (APOE2) under the direction of the human glial fibrillary acidic protein (GFAP) promoter and do not express endogenous mouse apolipoprotein E (APOE). The transgenic isoform expression pattern follows the endogenous mouse APOE and GFAP expression patterns in the brain. Human APOE2 is immunodetectable in glia and neuropil in developing and adult mutant mice. Cultured astrocytes from transgenic mice secrete APOE2 in lipoproteins that are similar in size to high-density (HDL) plasma lipoproteins. Detergent-soluble APOE2 protein levels in hemizygous mice forebrain tissue and in adult human cortex tissue are similar. Mice that are hemizygous or homozygous for the transgenic insert and homozygous for the targeted allele are viable, normal in size and do not display any gross physical or behavioral abnormalities.

| Mice homozygous for the Apobtm1Sgy and Apoetm1Unc targeted mutations do not express the apolipoproteins B100 or E. They do retain the ability to express apolipoprotein B48. They have the highest total cholesterol (392 mg/dl vs 341 for Apobtm1Unc/Apoetm1Unc); highest LDL cholesterol (APOB48 is not a ligand for LDLR), and atherosclerotic lesions more extensive than Apoetm1Unc/Apoetm1Unc homozygotes. The extent of atherosclerosis correlated significantly with plasma cholesterol levels. | ||

| Mice homozygous for the Apobtm2Sgy and Apoetm1Unc targeted mutations do not express the apolipoproteins B48 or E, they do express APOB100. Homozygotes are viable and fertile with no overt abnormalities. Compared to the APOB48 APOE deficient mice and the APOE deficient mice, they have the lowest total cholesterol (247mg/dl), lowest LDL cholesterol, and the least extensive Atherosclerotic lesions. The extent of atherosclerosis correlated significantly with plasma cholesterol levels. | ||

| Mice homozygous for the Apoetm1Unc and Ldlrtm1Hertargeted mutations on a normal chow diet show cholesterol levels corresponding to those seen in the Apoetm1Unc targeted mutant strain. The lipoprotein pattern in homozygous mice also resembles that seen in the Apoetm1Unc targeted mutant strain (VLDL & chylomicron remnants). The double targeted mice have a marked increase in both APOB48 and APOB100. In addition, APOAIV is increased. | ||
| 004362 | B6;129-Scarb1tm1Kri Apoetm1Unc/J | Repository-Cryopreserved |
| At birth, mice homozygous for both targeted alleles are viable, normal in size and do not display any gross physical or behavioral abnormalities. All double mutants die between 5 to 8 weeks following birth, exhibiting hypercholesterolemia and significantly lower body weights compared to control mice. Mice display an altered appearance several days before death, displaying ruffled fur, an abnormal gate and sometimes labored breathing. Hearts from double mutants are enlarged, exhibit evidence of myocardial infarction and are functionally impaired. Histological examination reveals extensive coronary artery disease characterized by atherosclerotic plaques with evidence of cholesterol clefts and fibrin deposition. As with other Scarb1 homozygous null mutants, females are infertile while the fertility of homozygous males remains intact. This double mutant mouse strain offers a model that may be a useful tool in studies related to coronary heart disease. | ||
| 002876 | B6;129S-Apobtm1Sgy/J | Repository-Cryopreserved |
| Mice homozygous for the Apob tm1Sgy targeted mutation are viable and fertile. They show normal expression of APOB48 in the gut but have no expression of APOB100. Homozygous mice show no developmental defects indicating that APOB100 synthesis in the yolk sac is not necessary for normal development. Homozygotes have lower serum LDL cholesterol levels compared to wildtype and APOB100 expressing mice (B6,129-Apob tm2Sgy, Stock No. 002877). | ||

| Mice homozygous for both the Ldlrtm1Her and Lrpap1tm1Her targeted mutations are viable and fertile. They have a functional deficiency of the low density lipoprotein receptor-related protein (LRP) and low density lipoprotein receptor (LDLR). LRP is reduced in both the liver and the brain of homozygotes. They also show impaired hepatic clearance of alpha2-macroglobulin and plasma accumulation of remnant lipoproteins. | ||
| 003807 | B6;129S-Seletm1Hyn Selltm1Hyn Selptm1Hyn/J | Repository-Cryopreserved |
| Mice that are homozygous null for the Sele, Sell and Selp genes are viable, fertile, normal in size, and do not display any gross physical or behavioral abnormalities at birth. As mice mature, however, they become susceptible to mucocutaneous infections that eventually lead to death. No Sele, Sell or Selp gene products (mRNA or protein) are detected. Leukocytes from these mice exhibit a deficiency in the ability to interact with, and roll along, the venular wall endothelium. This deficiency in the crucial first step of leukocyte recruitment to surrounding tissues in response to infection or injury contributes to an elevated leukocyte count in the peripheral blood. Delays in neutrophil and eosinophil recruitment to the peritoneum in response to thioglycollate and ragweed allergen, respectively, have been observed, specifically.

| 003806 | B6;129S-Seletm1Hyn Selltm1Hyn/J | Repository-Cryopreserved |
| Mice that are homozygous null for the Sele and Sell genes are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. No Sele or Sell gene products (mRNA or protein) are detected. A slightly diminished response in neutrophil recruitment to the peritoneum in response to thioglycollate is observed, as is a diminished ability to interact with the venular endothelium resulting in increased "rolling" along the vessel wall. These mice are suitable for use in research applications studying leukocyte homeostasis, infectious diseases and inflammation. | ||
| 002916 | B6;129S2-Seletm1Hyn Selptm1Hyn/J | Repository-Cryopreserved |
| Mice homozygous for both the Seletm1Hyn Selptm1Hyn mutations are viable and fertile. They are characterized by leukocytosis, spontaneous bacterial infections, dermatitis and defective leukocyte recruitment in many models of inflammation. | ||
| 002915 | B6;129S2-Seletm1Hyn/J | Repository-Cryopreserved |
| Mice homozygous for the Seletm1Hyn targeted mutation are viable and fertile. Homozygous mutant mice show only subtle defects in leukocyte recruitment, unless P-selectin (Selp) is also ablated or blocked with antibody. | ||
| 002896 | B6;129S4-Soat1tm1Far/J | Repository-Cryopreserved |
| Mice homozygous for the Soat1tm1 targeted mutation display tissue specific decreases in cholesterol esterification. Fibroblasts and adrenal membranes of homozygous mutant mice show diminished cholesterol esterification and markedly reduced cholesterol ester levels in adrenal glands and peritoneal macrophages. However, the livers of SOAT1-deficient mice contained substantial amounts of cholesterol esters and exhibited no reduction in cholesterol esterification activity. These findings support the presence of more than one form of esterification enzyme in mammals. A second sterol O-acyltransferase gene (Soat2), expressed in the liver and intestine, has subsequently been identified in mice and humans. | ||
| 002877 | B6;129S7-Apobtm2Sgy/J | Repository-Cryopreserved |
| Mice homozygous for the Apobtm2Sgy targeted mutation express only the APOB100 protein; development is normal and there are no intestinal abnormalities. LDL cholesterol is normal. These homozygoous mice have the lowest HDL cholesterol compared to wildtype and APOB48 expressing mice (B6,129-Apobtm1Sgy/J, Stock No. 002876). | ||
| 000604 | B6C3 a/A-T(10;13)199H +/+ Lystbg-J/J or Lystbg-2J/J | Repository-Cryopreserved |
| 000509 | C3H/HeJ-Lystbg-2J/J | Repository-Cryopreserved |
| Mice homozygous for the beige 2J spontaneous mutation (Lystbg-2J) display characteristics very similar to the original beige mutation (Lystbg). The mouse phenotype closely resembles Chediak-Higashi syndrome in man and similar conditions in mink and cattle. Abnormal giant lysosomal granules occur in all tissues with granule-containing cells, including granulocytes, lymphocytes, cells of the liver, kidney, central nervous system, pancreas, and thyroid, and the ducts of most glands; in type II pneumocytes; in mast cells; and in retinal pigment epithelium. Granulocytes from beige homozygous mutant mice show defective chemotaxis and reduced bactericidal activity. Beige mice are more susceptible than controls to pneumonitis and to various viral, bacterial, and parasitic infections. Natural killer (NK) cells from beige mice exhibit decreased endogenous cytotoxic activity. Beige mice also have a defective cytotoxic T-cell and cytotoxic antibody response to a

| 002244 | C57BL/6J-Tg(Apoa2)1Lus/J | Repository-Cryopreserved |
| This strain carryies the mouse apolipoprotein A-II transgene. Fasting plasma APOA2 concentrations in transgenic mice are on average about 3-fold higher than normal wildtype siblings with males showing a 1.5-fold higher level than females. ApoA-I concentraions are normal. These mice show a 3-fold increase in plasma triglyceride levels, as well as a predisposition to atherosclerotic fatty streak lesions even on a low fat diet. | ||
| 000494 | J.Cg-Oca2+ Tyr+ Lystbg/J | Repository-Cryopreserved |
| Mice homozygous for the beige spontaneous mutation (Lystbg) are characterized by a condition that closely resembles Chediak-Higashi disease in man and similar conditions in mink and cattle. Abnormal giant lysosomal granules occur in all tissues with granule-containing cells, including granulocytes, lymphocytes, cells of the liver, kidney, central nervous system, pancreas, and thyroid, and the ducts of most glands; in type II pneumocytes; in mast cells; and in retinal pigment epithelium. Granulocytes from beige homozygous mutant mice mice show defective chemotaxis and reduced bactericidal activity. Beige mice are more susceptible than controls to pneumonitis and to various viral, bacterial, and parasitic infections. Natural killer (NK) cells from beige mice exhibit decreased endogenous cytotoxic activity. Beige mice also have a defective cytotoxic T-cell and cytotoxic antibody response to allogeneic tumor cells. Syngeneic tumor cells grow better in beige mice than in l

| 000269 | SB/LeJ | Repository-Cryopreserved |
| The SB/Le inbred strain is homozygous for both the satin (Foxq1sa) and beige (Lystbg) mutations. Most of the immunological phenotype is due to the beige mutation. Homozygous mutant beige mice are characterized by a condition that closely resembles Chediak-Higashi disease in man and similar conditions in mink and cattle. Abnormal giant lysosomal granules occur in all tissues with granule-containing cells, including granulocytes, lymphocytes, cells of the liver, kidney, central nervous system, pancreas, and thyroid, and the ducts of most glands; in type II pneumocytes; in mast cells; and in retinal pigment epithelium. Granulocytes from beige mice show defective chemotaxis and reduced bactericidal activity. Beige mice are more susceptible than controls to pneumonitis and to various viral, bacterial, and parasitic infections. They have a severe deficiency of natural killer (NK) cells. Beige mice also have a defective cytotoxic T-cell and cytotoxic antibo

| 004192 | STOCK Mttptm2Sgy Ldlrtm1Her Apobtm2Sgy Tg(Mx1-cre)1Cgn/J | Repository-Cryopreserved |
| These mice are homozygous for four different induced mutations. The cumulative result of these mutations is a mouse model in which hypercholesterolemia can be reversed. By themselves, the combined presence of the Ldlrtm1Sgy and Apobtm1Sgy targeted alleles results in mice with a high susceptibility to atherosclerosis and total plasma cholesterol levels of approximately 300 mg/dl. A functional microsomal triglyceride transfer protein gene (Mttp) is essential for establishing a hypercholesterolemic condition. By flanking the Mttp gene with loxP sites and including a Mx1-Cre transgene, it is possible to reduce total plasma cholesterol levels from 300 mg/dl to 30 mg/dl upon induction of the Cre recombinase by administering interferon alpha, interferon beta, or synthetic double-stranded RNA. This unique model is useful in research related to the mechanisms and events of atherosclerotic reversal. Mice homozygous for the targeted
