Strain Information

Type Inbred Strain; Additional information on Inbred Strains. Mating System Sibling x Sibling         (Female x Male) Species laboratory mouse H2 Haplotype gx Generation F?+16+24 (24-JAN-08)

Appearance

Description
ALS/LtJ (Stock No. 003072) and ALR/LtJ inbred strains are of interest to investigators across a wide range of scientific disciplines including type 1 and type 2 diabetes, obesity, metabolism and toxicology research. Treatment of alloxan or streptozotocin causing pancreatic beta cell destruction, leads to severe hyperglycemia and hypoinsulinemia in ALS/LtJ mice. ALR/LtJ mice are resistant to these toxins. ALR/LtJ mice are of particular interest to investigators studying the immunogenetics of NOD/ShiLtJ mice in that the ALR/LtJ MHC haplotype (H2^gx) is a variant of the diabetogenic NOD H2^g7 haplotype. The (H2^gx) haplotype is identical to the H2^g7 haplotype from the H2-K end of the complex through the class II and class III region distal to Hsp70. However, at the distal H2-D end of the complex, ALR/LtJ mice have a rare H2-D^gx allele. Despite the similarities to the NOD/ShiLtJ mice, ALR/LtJ mice do not develop type 1 insulin dependent diabetes and thus provide an important control strain for NOD/ShiLtJ. ALR/Lt islets are unusually resistant in vitro to beta cell selective toxins known to generate free radicals (alloxan and streptozotocin). In addition, ALR/Lt islets are resistant to cytokine-mediated destruction. This resistance is correlated with an ALR strain-specific systematic elevation of enzymes and molecules associated with dissipation of free radicals. ALR/Lt mice of both sexes not treated with alloxan exhibit normal glucose tolerance, but gain weight rapidly, with females exhibiting male-like weight at 50 weeks of age. Understanding the genetic basis for the resistance of ALR mice to free radical mediated stressors, like alloxan and streptozotocin, as well as to immune system mediated stress, should prove valuable to pharmacologists interested in a variety of autoimmune and other diseases in which reactive oxygen species are associated with pathology.

Development
Alloxan is a pancreatic beta cell-selective toxin that induces diabetes in rodents by generating cytotoxic free radicals. The ALR (alloxan-induced diabetes-resistant) inbred strain was created in Japan by selective inbreeding of Crj:CD-1 (ICR) mice with selection for resistance to diabetes development after administration of alloxan at doses representing the ED50 for the original Crj:CD-1 strain (45 mg/kg in males, 47 mg/kg in females). These dosages are lower than what is necessary to elicit a strong diabetogenic response in most inbred strains, typically 60mg/kg. After a litter was born and weaned, the parents and some of the progeny were alloxan-treated to select for low versus high [ALS (alloxan-induced diabetes-susceptible)] incidence lines based on blood glucose levels at 7 days post treatment. ALS and ALR inbred strains were obtained from Japan by Dr. EH Leiter (Lt) at The Jackson Laboratory in 1996. ALS/Lt and ALR/Lt mice were transferred to the production colony in 1998. Genome wide scan demonstrated that ALR/LtJ mice are not only closely related to ALS/Lt mice, but also to two other ICR-derived inbred strains selected for diabetes susceptibility and distributed by The Jackson Laboratory: NOD/LtJ and NON/LtJ.

Molecular Note		Genetic complementation tests have shown allelism between the mdfw (modifier of deaf waddler) locus and the ahl locus. Further analysis has identified an association between ahl and a G to A transition at nucleotide position 753 of Cdh23. This hypomorphic allele causes in frame skipping of exon 7 and reduced message stability. Twenty-seven strains classified with ahl and carrying the 753A allele include: CD1, RBF/DnJ, PL/J, AKR/J, RF/J, BALB/cBy, A/WySnJ, P/J, SENCARA/PtJ, DBA/1J, ALS/LtJ, C58/J, C57BLKS/J, 129P1/ReJ, C57BR/cd, SKH2/J, BUB/Bn, MA/MyJ, LP/J, 129X1/SvJ, NOR/LtJ, A/J, C57BL/6, NOD/LyJ, DBA/2J, ALR/LtJ, C57L/J. Strains classified with ahl that DO NOT carry this mutation include: C3H/HeSnJ, I/LnJ,YBR/Ei, MRL/MpJ. [MGI Ref ID J:86905]

The Jackson Laboratory's Genotype Promise

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX^® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX^® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX^® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project.
