Fenofibrate is the ligand for PPARα subtype that mediates the action of its agonists' in lipid
metabolism. How fibrate exerts hypolipidemic effect? The mechanism is studied in a newly
developed high-fat fructose enriched diet induced dyslipidemia–diabetic hamster model.
Fenofibrate lowered the basal plasma lipids like TC, TG, PL, FFA, glycerol, VLDL, and LDL,
but HDL was increased. The activity of lipoprotein lipase in liver, adipose tissue, and small
intestine was upregulated. However, that of triglyceride lipase was downregulated in liver. It …
Fenofibrate is the ligand for PPARα subtype that mediates the action of its agonists’ in lipid metabolism. How fibrate exerts hypolipidemic effect? The mechanism is studied in a newly developed high-fat fructose enriched diet induced dyslipidemia–diabetic hamster model. Fenofibrate lowered the basal plasma lipids like TC, TG, PL, FFA, glycerol, VLDL, and LDL, but HDL was increased. The activity of lipoprotein lipase in liver, adipose tissue, and small intestine was upregulated. However, that of triglyceride lipase was downregulated in liver. It has also improved the insulin secretion and plasma glucose lowering, caused by impairment in insulin secretion due to high-fat load. The drug was found effective in reducing body weight and diet due to rise in leptin level. Fenofibrate also enhanced the fecal excretion of total lipids, cholic acid, and deoxycholic acid probably by the activation of 7α cholesterol hydroxylase enzyme. Thus, causing broad-spectrum lipid lowering along with inhibition of hepatic lipid biosynthesis and maintaining lipid–glucose homeostasis.
