Transcription profiling of fat and normal adipocytes from insulin receptor knockout mice sorted into small and large cells


ABSTRACT: Mice with fat-specific disruption of the insulin receptor gene (FIRKO mice) have low fat mass, and are protected against obesity and obesity-related glucose intolerance. FIRKO mice also exhibit polarization of adipocytes into populations of large and small cells. Other PubMed identifiers for this study: 15131120,12110165,15131119

Mice with a fat-specific insulin receptor knock-out (FIRKO) have reduced adipose tissue mass, are protected against obesity, and have an extended life span. White adipose tissue of FIRKO mice is also characterized by a polarization into two major populations of adipocytes, one small (<50 microm) and one large (>100 microm), which differ with regard to basal triglyceride synthesis and lipolysis, as well as in the expression of fatty acid synthase, sterol regulatory element-binding protein 1c, and  ...[more]
