Abstract

Glucose-dependent insulinotropic polypeptide (GIP) is best known as an incretin hormone that is secreted from K-cells of the proximal intestine, but evidence also implicates a role for GIP in regulating lipid metabolism and adiposity. It is well established that GIP receptor knockout (GIPR KO) mice are resistant to diet-induced obesity; however, the factors mediating this effect remain unresolved. Accordingly, we aimed to elucidate the mechanisms leading to adiposity resistance in GIPR KO mice with a focus on whole-body energy balance and lipid metabolism in adipose tissues. Studies were conducted in age-matched male GIPR KO and wild type (WT) mice fed a high-fat diet for 10 weeks. GIPR KO m..
