Lipids are thought to serve as coupling factors in insulin secretion. Hormone-sensitive lipase (HSL) is expressed in pancreatic beta-cells and could potentially regulate insulin secretion via mobilization of stored triglycerides. Here, we examined the impact of HSL deficiency on fuel metabolism and insulin secretion in mouse islets. Lack of HSL resulted in abrogation of neutral cholesterol ester hydrolase activity, whereas diglyceride lipase activity remained intact. Although glucose stimulates… CONTINUE READING
