The experiments performed in this report were designed to investigate the mechanisms involved in the metabolic alterations associated with orotic acid-induced hepatic steatosis and the effect of fenofibrate, a stimulant of peroxisome proliferators-activated receptor
(PPAR
), on these alterations. Male Wistar rats were divided into three experimental groups: 1) fed a balanced diet (C); 2) fed a balanced diet supplemented with 1%orotic acid (OA); 3) fed OA diet containing 100 mg.kg
− 1 bw.day
− 1 fenofibrate (OA + F), for 9 days.
