Donating InvestigatorDr. James Battey, Jr.,   National Institutes of Health

Description
Mice that are homozygous for the targeted mutation are viable, normal in size at birth and do not display any gross physical or behavioral abnormalities. This targeted mutation is X-linked; males bearing the targeted allele display a mutant phenotype. At 15 to 16 weeks of age male mice heterozygous for the mutant allele display increased body weight as compared to wildtype littermates. This mutant mouse strain represents a model that may be useful in studies related to energy metabolism and obesity.

Development
A targeting vector containing neomycin resistance and thymidine kinase genes was used to disrupt exon 2 of the targeted allele. The construct was electroporated into 129X1/SvJ derived Gsi1 embryonic stem (ES) cells. The resulting chimeric animals were backcrossed to C57BL/6 mice.

        B6.129X1-Brs3tm1Jfb
  • growth/size/body phenotype
  • increased body weight
    • mutants fed ad lib show significantly greater body weights than wild-type mice fed ad lib starting at 13 weeks of age and continuing throughout the experiment duration; by 32 weeks, mutant animals displayed 28% greater body weight than controls   (MGI Ref ID J:134021)
    • pair-feeding of mutant animals to match caloric intake of ad lib-fed wild-type normalized body weights of mutants so that pair-fed animal weights are similar to ad lib-fed wild-type mice   (MGI Ref ID J:134021)
    • at 10 weeks of age, pair-fed mutants are significantly heavier than wild-type mice   (MGI Ref ID J:134021)
  • adipose tissue phenotype
  • *normal* adipose tissue phenotype
    • increased weight at 10 weeks of age of pair-fed mutants does not correlate to increased brown adipose tissue compared to wild-type   (MGI Ref ID J:134021)
    • abnormal epididymal fat pad morphology   (MGI Ref ID J:134021)
    • increased brown adipose tissue amount
      • at 36 weeks of age, mutants have significantly more brown fat than wild-type mice   (MGI Ref ID J:134021)
    • increased white adipose tissue amount
      • increased weight at 10 weeks of age of pair-fed mutants is accompanied by significant increases in subcutaneous and epididymal fat   (MGI Ref ID J:134021)
      • at 36 weeks of age, mutants have significantly more subcutaneous and epididymal fat than wild-type mice   (MGI Ref ID J:134021)
  • homeostasis/metabolism phenotype
  • increased circulating insulin level
    • ad lib-fed mutants show significantly elevated insulin levels relative to ad lib fed wild-type mice   (MGI Ref ID J:134021)
    • pair-fed mutants showed normalized insulin levels to levels in ad lib-fed wild-type mice   (MGI Ref ID J:134021)
  • increased circulating leptin level
    • at 10 weeks of age, pair-fed mutants have elevated plasma leptin levels compared to wild-type animals   (MGI Ref ID J:134021)
  • behavior/neurological phenotype
  • abnormal food intake
    • ad lib-fed mutants show a decrease in grams of food consumed as percentage of body weight compared to wild-type at 20 and 28 weeks of age; less food is consumed relative to body weight   (MGI Ref ID J:134021)
    • increased food intake
      • over course of experiment, mutants fed ad lib show a higher food intake than ad lib-fed wild-type   (MGI Ref ID J:134021)
      • number of food pellets consumed in 24 hours greater in ad lib-fed mutants; number of meals taken in 24 hours is not different from ad lib-fed wild-type mice but meal size is significantly greater   (MGI Ref ID J:134021)

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.
