Details

Detailed Description

NRG-Akita mice, which are homozygous for the Rag1^tm1Mom and the Il2rg^tm1Wjl alleles (males are hemizygous for the X-linked Il2rg^tm1Wjl allele) and heterozygous for the Ins2^Akita allele, develop spontaneous hyperglycermia. No mature T, B or NK cells are detected in flow cytometric analysis of splenocytes from NRG-Akita mutant mice. Granulocyte and macrophage populations are similar to those seen in NRG mice (Stock No. 7799). NRG-Akita mice develop hyperglycemia between 3 and 5 weeks of age. Histological examination at 3 weeks of age reveals normal pancreas morphology, and routine insulin and glucagon staining. By approximately 32 weeks of age, NRG-Akita mice display disorganized, condensed pancreatic islet architecture, with loss of insulin-positive cells. Euglycemia is restored by subrenal transplantation of mouse or human islets or intrapancreatic transplantation of dissociated mouse islet cells. NRG-Akita mice engrafted with human hematopoietic stem cells (HSC) develop humanized immune systems. Approximately 60% of the human HSC engrafted NRG-Akita mice reject human islet allografts.

Development

To generate this strain NOD.Cg-Rag1^tm1Mom Ins2^Akita Prf1^tm1Sdz/SzJ (Stock No. 008659) mice were crossed with NOD.Cg-Rag1^tm1Mom Il2rg^tm1Wjl/SzJ (Stock No. 007799) mice. The Prf1^tm1Sdz allele was bred out, and the mice were made homozygous for the Rag1^tm1Mom and the Il2rg^tm1Wjl alleles and heterozygous for the Ins2^Akita allele with subsequent crosses.

Control Suggestions

Depending upon the nature of the experiment, the following may be an appropriate control: wildtype for Ins2^Akita from the colony.

Approximate Controls

001976 NOD/ShiLtJ
003729 NOD.129S7(B6)-Rag1^tm1Mom/J, (NOD.129S7(B6)-Rag1^tm1Mom/J (Stock No. 003729) may be an appropriate experimental control strain. )
007799 NOD.Cg-Rag1^tm1Mom Il2rg^tm1Wjl/SzJ, (NOD.Cg-Rag1^tm1Mom Il2rg^tm1Wjl/SzJ (Stock No. 007799) may be an appropriate experimental control strain.)

Genetics

Rag1^tm1Mom

Allele Symbol: Rag1^tm1Mom

Allele Name	targeted mutation 1, Peter Mombaerts
Allele Type	Targeted (Null/Knockout)
Allele Synonym(s)	Rag-; Rag^1tm1Mom; RAG-1-; Rag1^-; RAG1^null; Rag-1KO
Gene Symbol and Name	Rag1, recombination activating gene 1
Gene Synonym(s)
Site of Expression	expression is seen in bone marrow derived cell lines.
Strain of Origin	129S7/SvEvBrd-Hprt⁺
Chromosome	2
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.
Mutations Made By	Peter Mombaerts, Max Planck Research Unit for Neurogenetics

Il2rg^tm1Wjl

Allele Symbol: Il2rg^tm1Wjl

Allele Name	targeted mutation 1, Warren J Leonard
Allele Type	Targeted (Null/Knockout)
Allele Synonym(s)	[KO]gammac; CD132^-; gammac^-; gc^-; Il2rg^tm1Wjll; IL2Rgamma^null
Gene Symbol and Name	Il2rg, interleukin 2 receptor, gamma chain
Gene Synonym(s)
Site of Expression	Primarily lymphoid cells.
Strain of Origin	129S4/SvJae
Chromosome	X
Molecular Note	A neomycin resistance cassette replaced part of exon 3 and all of exons 4 - 8 of the gene, resulting in the loss of most of the extracellular domain and all of the transmembrane and cytoplasmic domains of the protein.
Mutations Made By	Dr. Warren Leonard, NHLBI, NIH

Ins2^Akita

Allele Symbol: Ins2^Akita

Allele Name	Akita
Allele Type	Spontaneous
Allele Synonym(s)	Akita; Akita^Ins2; Ins2^C96Y; Ins2^Mody; Mody; Mody4
Gene Symbol and Name	Ins2, insulin II
Gene Synonym(s)
Strain of Origin	C57BL/6NSlc
Chromosome	7
Molecular Note	In the mutant allele a transition from G-to-A at coding nucleotide 287 disrupts 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) (p.C96Y). 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.

Breeding Considerations

The Donating Investigator maintained the strain by crossing female mice that are homozygous for the Rag1^tm1Mom and the Il2rg^tm1Wjl alleles (not carrying the Ins2^Akita allele) with male mice that are homozygous for the Rag1^tm1Mom allele, hemizygous for the Il2rg^tm1Wjl allele and heterozygous for the Ins2^Akita allele.

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. We do not guarantee breeding performance and therefore suggest that investigators order more than one breeding pair to avoid delays in their research.
