Additional information on JAX® GEMM® Strains.
Type JAX® GEMM® Strain - Targeted Mutation
Mating SystemHomozygote x Homozygote         (Female x Male)
Specieslaboratory mouse
Donating Investigator Richard Palmiter,   University of Washington
GenerationN?+F?+F10 (31-DEC-07)

Strain Description
Mice that are homozygous for the targeted mutation are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. No gene product (mRNA or protein) is detected by Northern or Western blot analysis of brain or adrenal gland tissue. Beta-galactosidase activity assays and in situ hybridization demonstrate similar expression patterns for the lacZ gene and the endogenous wildtype gene. Spontaneous seizures are exhibited by some mice at age 6 to 8 weeks. Homozygous mice are susceptible to seizures induced by GABA antagonist treatment. Mutant mice have an increased sensitivity to leptin treatment which results in a greater initial reduction of food intake and weight loss when compared to wildtype mice. This mutant mouse strain may be useful in studies related to the role of neuropeptide Y in obesity.

Strain Development
A targeting vector containing neomycin resistance, thymidine kinase and lacZ reporter genes was used to disrupt exon 2 of the targeted gene. The construct was electroporated into 129S6/SvEvBrd-Hprt+ derived AB1 embryonic stem (ES) cells. Correctly targeted ES cells were injected into C57BL/6 blastocysts.

Mammalian Phenotype Terms assigned by genotype

Npytm1Rpa/Npytm1Rpa

        involves: 129S7/SvEvBrd
  • behavior/neurological phenotype
  • sporadic seizures (MGI Ref ID J:33261)
    • mice exhibited occasional mild seizures at 6-8 weeks of age, with decreased frequency until 9 weeks and were not seen thereafter; seizures consisted of jerking of the head and body, tail extension and vocalization
  • susceptibility to pharmacologically induced seizures (MGI Ref ID J:33261)
    • pentylenetrazole (PTZ) treatment at 50 or 60 mg/kg induced convulsions in 80% of mutant mice compared to 33% of controls
    • convulsions in the mutant mice were also scored as more severe
  • homeostasis/metabolism phenotype
  • *normal* homeostasis/metabolism phenotype (MGI Ref ID J:33261)
    • no defects were observed in food intake, body weight and adiposity
    • normal glucose homeostasis was also noted
    • responses to food deprivation was similar to controls
    • susceptibility to pharmacologically induced seizures (MGI Ref ID J:33261)
      • pentylenetrazole (PTZ) treatment at 50 or 60 mg/kg induced convulsions in 80% of mutant mice compared to 33% of controls
      • convulsions in the mutant mice were also scored as more severe
  • nervous system phenotype
  • sporadic seizures (MGI Ref ID J:33261)
    • mice exhibited occasional mild seizures at 6-8 weeks of age, with decreased frequency until 9 weeks and were not seen thereafter; seizures consisted of jerking of the head and body, tail extension and vocalization
  • susceptibility to pharmacologically induced seizures (MGI Ref ID J:33261)

Molecular Note Exon 2, which encodes the signal peptide and 35 amino acids, was replaced by a lacZ-neo fusion gene. The expression pattern of the beta-galactosidase was shown to resemble that of the endogenous gene via comparisons of X-gal staining and previous in situhybridization studies. RT-PCR analysis of brain tissue showed an absence of transcript in homozygous mutant mice. [MGI Ref ID J:33261]

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.
