| 004337 | 129(Cg)-Foxg1tm1(cre)Skm/J | Repository- Live |
| This strain expresses Cre recombinase from the endogenous Foxg1 locus. Forkhead box G1 is required for telencephalon development and is expressed specifically in the telencephalon and discrete head structures. When crossed with a strain containing loxP site flanked sequence of interest, Cre-mediated recombination results in tissue-specific deletion of the target. Recombination occurs in the telencephalon, anterior optic vesicle (developing lens and retina), otic vesicle, facial and head ectoderm, olfactory epithelium, mid-hindbrain junction and pharyngeal pouches. Mice that are homozygous for the targeted mutation die perinatally. Heterozygous mutant mice are viable, fertile, 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 of telencephalic development. | ||
| 012431 | B6.129-Adrbk2tm1Rjl/J | Repository- Live |
| Adrbk2 (adrenergic receptor kinase, beta 2; also called GRK3) is the major G protein-coupled receptor kinase family member in olfactory neurons, and mice lacking GRK3 exhibit a deficit in desensitization to olfactants. In homozygous mice, airway smooth muscle cells exhibit supersensitivity to muscarinic agents, and brain neurons exhibit altered kappa opioid receptor-dependent tolerance. Expression is eliminated in olfactory neuroepithelium, brain, and airway smooth muscle cells. | ||
| 006084 | B6.129P2(Cg)-Foxg1tm1(cre)Skm/J | Repository- Live |
| This strain expresses Cre recombinase from the endogenous Foxg1 locus. Forkhead box G1 is required for telencephalon development and is expressed specifically in the telencephalon and discrete head structures. When crossed with a strain containing loxP site flanked sequence of interest, Cre-mediated recombination results in tissue-specific deletion of the target. Recombination occurs in the telencephalon, anterior optic vesicle (developing lens and retina), otic vesicle, facial and head ectoderm, olfactory epithelium, mid-hindbrain junction and pharyngeal pouches. Mice that are homozygous for the targeted mutation die perinatally. Heterozygous mutant mice are viable, fertile, normal in size. On the C57BL/6 background, forebrain volume in heterozygotes is substantially reduced especially in the cerebral cortex (40.7%), striatum (29.7%), and hippocampus (18.6%). In the adult, the thalamus is reduced in volume by 21.6%. This mutant mouse strain represents a model that ma ..... For more information please see the full phenotype on the strain data sheet | ||
| 000031 | BXD24/TyJ-Cep290rd16/J | Repository- Live |
| The BXD RI strains are used to study the genetics of behavioral phenotypes including alcohol and drug addiction, stress, and locomotor activity. The BXD set of RI strains also are used in the genetic analysis of numerous complex or potentially complex physiologic phenotypes including differences in organ weight and bone mineral density. The strain distribution pattern (SDP) for BXD RI strains is available through the Mouse Genome Informatics Recombinant Inbred Strain Distribution Patterns Query Form.
In 2004, a spontaneous mutation, rd16, was discovered in this recombinant inbred line. Mice exhibit complete degeneration of retinal photoreceptors (Seecharan et al. 2003) resulting in blindness. | ||
| 009091 | 129-Skitm1Cco/J | Cryopreserved - Ready for recovery |
| Mice homozygous for the targeted mutation die before or shortly after birth due to developmental defects. More than 80% of homozygotes on the 129 background exhibit exencephaly (severe neural tube closure defects) between embryonic day 15.5 (E15.5) and embryonic day 18.5 (E18.5). None exhibit facial clefting. The Donating Investigator reports that homozygotes display flattened or shorter snouts, iris malformation and polydactyly. The penetrance of the phenotype is highly background dependent. Heterozygotes are viable and fertile with timely cranial neural tube closure and, the Donating Investigator reports, no facial clefting. This mutant strain may be useful in studies of facial cleft formation, 1p36 deletion syndrome, oncogene function, apoptosis, and neural tube and skeletal muscle defects. | ||
| 009092 | A.129P-Skitm1Cco/J | Cryopreserved - Ready for recovery |
| Mice homozygous for the targeted mutation die before or shortly after birth due to developmental defects. Homozygotes on the A/J background exhibit exencephaly (severe neural tube closure defects), with a higher embryonic lethality than homozygotes on the C56BL/6 or 129 backgrounds. None exhibit facial clefting. The Donating Investigator reports that homozygotes display flattened or shorter snouts, iris malformation and polydactyly. The penetrance of the phenotype is highly background dependent. Heterozygotes are viable and fertile with timely cranial neural tube closure, and a low incidence of facial clefting. The Donating Investigator reports some heterozygotes on the A/J background exhibit lateral facial clefting. This mutant strain may be useful in studies of facial cleft formation, 1p36 deletion syndrome, oncogene function, apoptosis, and neural tube and skeletal muscle defects. | ||
| 009644 | B6.129-Cby1tm1Ktkm/J | Cryopreserved - Ready for recovery |
| Homozygous targeted mice are runted and demonstrate a failure to thrive. Most die before or around weaning age. Mice surviving after postnatal day 25 (P25) usually recover and apparently have normal life spans. All of the mice develop rhinitis and sinusitis and are unable to clear Pseudomonas aeruginosa bacteria from the nasal cavity. There is a complete absence of mucociliary transport caused by a marked lack of motile cilia in the nasal epithelium. Anemia and ductal dilation in the pancreas and kidneys is also observed. Homozygous males have compromised fertility. This strain may be useful as a model of primary ciliary dyskinesia. | ||
| 005709 | B6.129-Skitm1Cco/J | Cryopreserved - Ready for recovery |
| This mutant was created on a mixed (129 x C57BL/6J) background. Greater than 80% of mice on this mixed background had severe neural tube closure defects (such as exencephaly) while less than 16% exhibited facial clefting. The penetrance of these phenotypes has segregated with further backcross to C57BL/6J. The congenic mutant described here was backcrossed 12-14 times to wildtype C57BL/6J. Mice homozygous for the targeted mutation die before or shortly after birth due to developmental defects. Null mice are distinguishable from wildtype and heterozygous littermates at embryonic day 8.5 (E8.5) with delayed, but complete, cranial neural tube closure (incomplete at the normal E9.5). Ninety percent of null mice alive at E18.5 exhibit facial clefting. Other highly penetrant phenotypes include flattened snout, depressed nasal bridge, excessive orbital separation, elongated subventricular zones, vestigial polydactyly, and malformations of the olfactory bulb, iris, and ventral septum. Heterozy ..... For more information please see the full phenotype on the strain data sheet | ||
| 002905 | B6.129S1-Cnga2tm1Ngai/J | Cryopreserved - Ready for recovery |
| Heterozygous females are normal. Hemizygous males usually die within 1-2 days of birth from an apparent failure to suckle. A few (~1%) survive to adulthood. They will mate and are fertile. They are completely anosmic. This is an X-linked gene. | ||
| 001271 | B6.RBF(C3Fe)-Nek1kat/J | Cryopreserved - Ready for recovery |
| The phenotype associated with the Nek1kat-2J allele is more severe than that of the Nek1kat allele. Mice homozygous for Nek1kat-2J all die before one year of age, a third of those that survive weaning die suddenly before 100 days of age, and the reported median survival age is 211 days. Mice homozygous for Nek1kat also have a shortened life expectancy with high pre-weaning mortality and a reported median survival of 286 days, but 22% were found to survive beyond 1 year. Both mutants are runted and have blunted noses with olfactory bulbs that are approximately half the normal size and lack most of the glomerular and external granular layers. In the brain there is dilation of the lateral and third ventricles, cerebral aqueduct and fourth ventricle along with large, fluid-filled cysts in the choroid plexus. Hydrocephalus occurs. Normochromic normocytic anemia is found and is more pronounced in Nek1Kat-2J ..... For more information please see the full phenotype on the strain data sheet | ||
| 011064 | B6;129-Cnga4tm1Reed/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) is detected by in situ hybridization analysis of olfactory receptor neurons from homozygotes. Beta-galactosidase expression is faintly detected in an incomplete mimic of the endogenous gene expression pattern, by histochemical analysis of olfactory epithelium and olfactory bulb. Olfactory receptor neuron channels from homozygotes have reduced desensitization rate and decreased affinity for cAMP. Homozygotes exhibit defective odor detection ability and reduced rate of odor adaptation due to impaired Ca2+-calmodulin mediated channel desensitization. | ||
| 006720 | B6;129P2-Olfr124tm4Mom/MomJ | Cryopreserved - Ready for recovery |
| Olfactory sensory neurons with the Olfr124 locus actively transcribed can be identified as expressing red fluorescent protein, even though no OLFR124 protein is expressed. The density of these cells in the septal organ is 14 times lower than OLFR124 expressing cells in mice with an intact Olfr124 locus tagged with an IRES-tauGFP. Of the OLFR124 deficient neurons, only 18% in the septal organ and only 14% in the main olfactory epithelium responded to all 5 odorants that stimulate 100% of OLFR124 expressing olfactory sensory neurons. This indicates that OLFR124 is responsible for the unusually broad response profile of the olfactory sensory neurons that express it. | ||

| 005128 | STOCK Sema7atm1Alk/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) is detected by Northern blot analysis. By age embryonic day 16, homozygotes exhibit abnormal lateral olfactory tract outgrowth. The lateral olfactory tract (LOT) from mutants have a more narrow morphology when compared to wildtype controls. In many mutants, no LOT is detected in the most caudal regions. This mutant mouse strain may be useful in studies of lateral olfactory tract development and axonal growth. | ||
| 006674 | STOCK Tg(Olfr16,taulacZ)2030Mom/MomJ | Cryopreserved - Ready for recovery |
| Hemizygous mice express a mini-transgene for the olfactory receptor MOR23. Olfactory sensory neurons that express MOR23 co-express the taulacZ fusion protein by virtue of IRES-mediated co-translation. These neurons can be revealed by histochemistry of beta-galactosidase enzymatic activity, or by immunofluorescence with anti-beta-galactosidase antibodies. These mice may be useful in studies of axon guidance and mechanisms of olfactory receptor specificity in the olfactory bulb. | ||
