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.

| Molecular Note | In the mutant allele a transition from G to A at nucleotide 1907 disrupted an Fnu4HI site in exon 3. This mutation changed the seventh amino acid in the A chain of mature insulin, Cys96 (TGC), to Tyr (TAC). The authors predict that the transition would disrupt a disulfide bond between the A and the B chains and would likely induce a major conformational change in insulin 2 molecules. RT-PCR studies suggest that both normal and mutant Ins2 alleles are transcribed similarly in pancreatic islets of heterozygous mice, although immunofluorescence and immunoblot analyses of heterozygous islets detected reduced levels of insulin and proinsulin.

| Gene Symbol and Name | Rag1, recombination activating gene 1 | ||
| Chromosome | 2 | ||
| Gene Common Name(s) | MGC43321; RNF74; Rag-1; | ||
| Molecular Note | A 1356 bp genomic fragment of the Rag1 gene, encoding the nuclear localization signal and the zinc-finger motif, was replaced by a neomycin cassette. A mutant transcript expressed from this allele was detected by Northern blot in bone marrow derived cell lines from homozygous mice. [MGI Ref ID J:1934] [MGI Ref ID J:96036] | ||

| 000664 C57BL/6J | ||
| Appropriate controls depend on the nature of the experiment. C57BL/6J mice or C57BL/6-Ins2Akita may be used as controls. Alternatively, mice from the colony that are wild-type for the Ins2Akita mutation but homozygous for the Rag1tm1Mom mutation may also be appropriate. | ||

Ins2Akita
Rag1tm1Mom
| Breeding & Husbandry | This strain is maintained by breeding wildtype females (Rag1-/-Ins2+/+) to affected (hyperglycemic) males (Rag1-/-Ins2Akita/+). The Rag1tm1Mom allele is maintained in homozygosity and the Ins2Akita allele is maintained in heterozygosity. After onset of diabetes, when cages become very wet due to polyuria, the health of Ins2Akita heterozygotes is best maintained by housing them individually in cages containing a mixture of regular litter and Alpha-Dri, changed twice weekly. Specific pathogen free (SPF) conditions are recommended. Expected coat color is Black. |
