Donating Investigator Gustav E. Lienhard,   Dartmouth Medical School

Description
Mice homozygous for the Irs4tm1Lhd targeted mutation are viable and fertile. However, homozygous mutant mice do appear to be at a greater risk of perinatal lethality and tend to produce fewer litters. At birth, surviving mice appear normal in size and do not display any gross physical or behavioral abnormalities. RT-PCR fails to detect Irs4 mRNA in any tissues analyzed. Growth rate appears to be slightly retarded beginning 6 weeks of age (males about 10% lighter). Homozygotes also exhibit impaired glucose tolerance, and have slightly lower blood glucose levels when compared to wildtype mice. These phenotypes are more pronounced in males than in females.

Development
A targeting vector containing a herpes simplex virus thymidine kinase gene and a neomycin resistance gene driven by the mouse phosphoglycerate kinase promoter was used to disrupt the single Irs4 exon. The construct was electroporated into 129S4/SvJae-derived J1 embryonic stem (ES) cells. Correctly targeted ES cells were injected into C57BL/6 blastocysts. The resulting chimeric male mice were bred to C57BL/6 females. Offspring animals were bred to homozygosity.

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.
