JAX^® Mice Strains

Stock Number	Strain Name Strain Description	Standard Supply
000486	MRL/MpJ	Level 2
	The MRL/MpJ mice are large but docile to the point that males rarely fight. They are the parent and control strain for for MRL/MpJ-Fas^lpr (Stock Nos. 000485, 006825). Despite carrying the normal Fas gene, MRL/MpJ mice also exhibit autoimmune disorders, but symptoms are manifested much later in life compared to those the MRL/MpJ-Fas^lpr mice. Starting at about three months of age, levels of circulating immune complexes rise greatly in the MRL-Fas^lpr mouse but not in the wildtype control, MRL/MpJ. Also beginning at 3 months Fas^lpr mice exhibit very severe poliferative glomerulonephritis, whereas in the MRL/MpJ controls usually only mild glomerular lesions are detected. MRL/MpJ inbred female typically die at 73 weeks of age and males die at 93 weeks. This compares to a lifespan of 17 weeks in the female and 22 weeks for males in the mouse homozygous for Fas^lpr.

000485	MRL/MpJ-Fas^lpr/J	Level 4
	Mice homozygous for the lymphoproliferation spontaneous mutation (Fas^lpr) show systemic autoimmunity, massive lymphadenopathy associated with proliferation of aberrant T cells, arthritis, and immune complex glomerulonephrosis. Starting at about three months of age, levels of circulating immune complexes rise greatly in the MRL-lpr/lpr mouse but not the MRL normal (Hewicker 1990). Onset and severity of symptoms associated with the Fas^lpr gene is strain-dependent. For example, lymphoproliferation varies greatly with congenic strain C57BL/6J-Fas^lpr/Fas^lpr at a 24 fold increase over control lymph node weight, MRL/Mp-Fas^lpr/Fas^lpr at 75 fold and congenic strain C3H/HeJ-Fas^lpr/Fas^lpr highest at 116 fold increase over control lymph node weight (Morse et al 1985). Variance in renal pathology ranks from extensive in MRL/Mp-Fas^lpr > ..... For more information please see the full descriiption on the strain data sheet
002507	B6.129S2-Serpine1^tm1Mlg/J	Repository- Live
	Mice homozygous for this mutation develop normally and are viable and fertile. Compared to wild type mice, pulmonary clot lysis is increased in the heterozygote and further increased in the homozygote. Endotoxin induced venous thrombosis is decreased compared to wild type mice. Thus, disruption of the Serpine1 gene induces a mild hyperfibrinolytic state. Hemostasis is normal in homozygous mutants.
006238	B6;129S4-Thbs2^tm1Bst/J	Repository- Live
	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. In an attempt to offer alleles on well-characterized or multiple genetic backgrounds, alleles are fre ..... For more information please see the full descriiption on the strain data sheet
000675	LG/J	Repository- Live
	LG/J mice develop antinuclear antibodies and rheumatoid factor as well as renal disease characterized by glomerulonephritis, interstitial nephritis, and perivasculitis (Peng et al., 1996). LG/J was the predominant strain used to develop the MRL/LpJ (Stock No. 000486) inbred strain, a model for autoimmunity. LG/J mice are often compared to SM/J (Stock No. 000687) for quantitative trait locus analysis in the areas of atherosclerosis, obesity, and mandible size . These mice are susceptible to diet-induced obesity and diet-induced atherosclerosis.
006825	MRL/MpJ-Fas^lpr/2J	Repository- Live
	The current colony (as of fall 2006) of MRL/MpJ-Fas^lpr/J has experienced a progressive loss of lymphoproliferative phenotype over the past several years, as reported by some of our customers and as observed by our technical staff. This loss of phenotype has been manifested by reduced enlargement of brachial and mesenteric lymph nodes, and poor splenomegaly. Also, the life spans of the mice in the current colony have also been found to be much longer than the historically observed and reported 17 weeks for females and 22 weeks for males. However, genotyping continues to show that all the mice in the colony remain homozygous for the Fas^lpr mutation, and the SNP profile in the region of the mutation on Chromosome 19 has not changed. In an effort to regenerate the desired phenotype, we recovered mice from our embryo archive cryopreserved in 1993. The sixteen-week old cryo-recovered mice have lymph nodes that were 4.5 (females) to 10.1 times (male) la ..... For more information please see the full descriiption on the strain data sheet
002324	FVB.129S2-Serpine1^tm1Mlg/J	Repository-Cryopreserved
	Mice homozygous for this mutation develop normally and are viable and fertile. Compared to wild type mice, pulmonary clot lysis is increased in the heterozygote and further increased in the homozygote. Endotoxin induced venous thrombosis is decreased compared to wild type mice. Thus, disruption of the Serpine1 gene induces a mild hyperfibrinolytic state. Hemostasis is normal in homozygous mutants.
