Potent and Selective PPAR-α Agonist LY518674 Upregulates Both ApoA-I Production and Catabolism in Human Subjects With the Metabolic Syndrome

Abstract

Activation of PPAR-alpha with LY518674 (100 microg) in subjects with metabolic syndrome and low HDL-C increased the VLDL apoB-100 FCR consistent with enhanced lipolysis of plasma triglyceride. Significant increases in the apoA-I and apoA-II production rates were accompanied by increased FCRs resulting in no change in HDL-C levels. These data indicate a major effect of LY518674 on the production and clearance of apoA-I and HDL despite no change in the plasma concentration. The effect of these changes on reverse cholesterol transport remains to be determined.
