The long-term goal of the Buhman laboratory is to identify novel factors that regulate dietary fat sensing, metabolism or absorption that may be exploited for preventive and therapeutic interventions for obesity, diabetes, and heart disease. Research in the Buhman laboratory focuses on trafficking and metabolism of digestive products of dietary fat within the absorptive cells of the small intestine, enterocytes. Projects in the Buhman laboratory are currently addressing how diet, drugs and genetics affect chylomicron synthesis and secretion, cytoplasmic lipid droplets synthesis and metabolism, and fatty acid oxidation by enterocytes. Recent publications from the Buhman laboratory highlight important functions of diet, drugs, and genetics in regulation of dietary fat processing within enterocytes that results in effects related to metabolic diseases such as body weight, blood lipid concentrations, and hepatic steatosis.
