Fibrates are a group of hypolipidemic agents which efficiently lower serum triglyceride levels by affecting the expression of many genes involved in lipid metabolism. These effects are exerted via the peroxisome proliferator-activated receptor alpha (PPARa). In addition, fibrates also lower serum cholesterol levels, suggesting a possible link between the PPARa and cholesterol metabolism. Bile acid formation represents an important pathway for elimination of cholesterol, and the sterol 12a-hydroxylase is a branch-point enzyme in the bile acid biosynthetic pathway, which determines the ratio of cholic acid to chenodeoxycholic acid. Treatment of mice for one week with the peroxisome proliferator WY-14,643 or …
