Current opinion in lipidology, 24(3), 239-245 (2013-04-27)
This review focuses on the current understanding of the physiological mechanisms of action of niacin on lipid metabolism and atherosclerosis. Emerging findings indicate that niacin decreases hepatic triglyceride synthesis and subsequent VLDL/LDL secretion by directly and noncompetitively inhibiting hepatocyte diacylglycerol
