Former Common nameGIPR Knockout mice
H-2 Haplotype
ES Cell line
Background strainC57BL/6NCrSlc
Appearanceblack [a/a B/B C/C]
Strain developmentDeveloped by Dr. Yutaka Seino, Kyoto University in 1999. A neomycin cassette was inserted to replace exons 4 and 5 of GIPR gene. The mutant mice were backcrossed to C57BL/6.
Strain descriptionB6.129P2-Gipr<tm1Yse>. Gastric inhibitory polypeptide (GIP) is a gastrointestinal peptide hormone synthesized by K cells in the duodenum and small intestine, GIP plays a role in gastric secretory inhibition, gastric mobility, and insulin release by binding to its specific receptor, the GIP receptor (GIPR). Homozygous mutant mice for Gipr<tm1Yse> targeted mutation are fertile and viable, but exhibit hyperglycemia after high-fat diet ingestion. This strain is useful for elucidating of the signaling mechanism of GIP from pancreatic beta cell to intestine.
Colony maintenanceBackcross to C57BL/6 (Heterozygote x C57BL/6CrSlc)Homozygous mice are fertile and viable.
