The Lewis lab has had a long interest in the mechanisms of various aspects of diabetic dyslipidemia, including postprandial lipemia, High-density Lipoprotein (HDL) lowering and hypertriglyceridemia. We have also had a long standing interest in the interaction between free fatty acids and pancreatic beta cell dysfunction. Previously, we have performed animal and human mechanistic studies but are now focusing exclusively on human studies. In 2002, working in close collaboration with Dr. Khosrow Adeli (U of T), we made the novel observation that the intestine, in addition to the liver, overproduces lipoproteins in insulin resistant states. In our current CIHR-funded work, we are determining the mechanism of intestinal and hepatic lipoprotein overproduction in insulin resistance and type 2 diabetes. We perform integrative, physiological studies in humans, attempting to determine the regulation of intestinal and hepatic lipoprotein particle production by hormones, nutrients and pharmacological agents.
