Effect of Nicotinic Acid on Adipose Tissue Inflammation in Obese Subjects

Summary

Our working hypothesis postulates that lipolysis is a determinant of inflammation in adipose tissue (AT). Inhibition of lipolysis, e.g. using the oldest normolipidemic drug, nicotinic acid, has proved valuable to combat the metabolic syndrome. Our proposal will determine whether part of the beneficial effects of this antilipolytic compound is due to a diminution of AT inflammation. To this aim, the effect of nicotinic acid or placebo will be studied in male obese subjects with or without a training program which goal is to enhance lipolysis.
