Description
Mice homozygous (females) or hemizygous (males) for the X-linked Grprtm1Jfb targeted mutation are viable with no gross phenotypic abnormalities observed. There is a deficiency in bombesin-induced mediation of satiety as measured by glucose intake. A modest increase in body weight is observed in older animals. At 18-20 months of age, hemizygous males (N = 8) are 44.5g ± 5.1 (mean ± std dev) and wildtype littermates (N = 8) are 38.3g ± 5.1 (L. Hampton, unpublished observation). We have recently observed head tilts and bobbing in the hemizygous males in our production colony. The donating investigator of this strain has also observed this phenotype and considers it a mutation not related to the gene. We are working to remove this phenotype, but we will continue to ship from the colony while we finish this process.

Development
A targeting vector containing neomycin resistance and herpes simplex virus thymidine kinase genes was used to disrupt exon 1. The construct was electroporated into 129X1/SvJ derived RW-4 embryonic stem (ES) cells. Correctly targeted ES cells were injected into recipient blastocysts. The resulting chimeric animals were crossed to C57BL/6J mice, and then backcrossed to the same for 8 generations.

Grprtm1Jfb/Grprtm1Jfb

        involves: 129X1/SvJ * C57BL/6J
  • normal phenotype
  • no abnormal phenotype detected (MGI Ref ID J:46897)
    • female homozygotes are viable, fertile and developmentally normal with no pathological or histological abnormalities in all major organ systems up to 10 months of age

Grprtm1Jfb/Y

        involves: 129X1/SvJ * C57BL/6J
  • behavior/neurological phenotype
  • abnormal food intake (MGI Ref ID J:46897)
    • male hemizygotes are viable, fertile and developmentally normal with no pathological or histological abnormalities in all major organ systems up to 10 months of age
    • however, male hemizygotes lack a bombesin (BN)-induced satiety response: BN produces a significant suppression of glucose intake in wild-type mice at doses of 3.2, 10, and 32 nmol/kg but fails to suppress glucose intake at any dose with no apparent weight gain in mutant males

Supply Notes
  • Cryorecovery - Standard.
    The recovery process begins when a signed agreement form is returned to the Customer Service Department after order placement. Although results vary by strain, at least two males and two females (two pairs) will be provided, typically within 15 weeks of our receipt of the signed agreement form. If the first recovery attempt is unsuccessful or only one pair is recovered, a second recovery will be done, extending the delivery time to approximately 25 weeks. At least one member of each pair will be of known genotype and will carry the mutation if it is a mutant strain. Please note that pairs may not reflect the mating scheme utilized by The Jackson Laboratory prior to cryopreservation of the strain. Mating schemes are sometimes modified for successful cryopreservation. Price represents a repository maintenance fee, which includes the cost of recovery of the strain from the cryopreservation resource and the periodic replacement of the frozen embryos used for recovery.

    Cryorecovery to establish a Dedicated Supply for greater quantities of mice.
    One to two pairs will be recovered to establish a Dedicated Supply of mice. Price by quotation. For more information on Dedicated Supply, please contact JAX® Services, Tel: 1-800-422-6423 or 1-207-288-5845.

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.
