M Wang , SM Pugh , J Daboul , D Miller , Y Xu , JW Hill

Brief Summary: IGF1R signaling in cells expressing Kiss1 gene affects energy balance, food intake, and physical activity in a sex-specific manner. Female IGF1RKiss1 mice showed lower body weight and food intake plus higher energy expenditure and physical activity. This phenotype was associated with higher proopiomelanocortin (POMC) expression. The additional deletion of insulin receptor (IR) in Kiss1-expressing cells reversed the lean phenotype seen in female IGF1R<...
