Disruption of Epithelial HDAC3 in Intestine Prevents Diet-Induced Obesity in Mice.

ABSTRACT: BACKGROUND & AIMS:Intestinal microbiota modulate metabolism and associate closely with epithelial cells in the intestine. In intestinal epithelial cells (IECs), histone deacetylase 3 (HDAC3) integrates microbiota-derived signals to control intestinal homeostasis. We investigated whether HDAC3 in IECs regulates metabolism and the development of obesity in mice. METHODS:Adult C57BL/6 (control) mice and mice with constitutive or inducible IEC-specific disruption of Hdac3 (HDAC3ΔIEC mice) were placed on a standard chow or high-fat diet (HFD, 60% kcal from fat). We measured body composition, weight, glucose tolerance, and energy expenditure. IECs were isolated from small intestine and gene expression, and lipid levels were analyzed. HDAC3 levels were determined in 43 pediatric patient ileal bio
