ABSTRACT

AIM:

To investigate the effects of sodium ferulate on cholesterol and triglyceride metabolism in atherosclerosis with hyperlipidemia.

METHODS:

The rabbit model of atherosclerosis was produced by feeding high lipid forages.RAW264.7 foam cell and HepG2 injured cell models were established by incubation with oxidized low density lipoprotein(ox-LDL).The atherosclerotic plaque area was measured,and serum lipids were detected.The cellular lipid accumulation was examined by oil red O staining.The cellular contents of total cholesterol and cholesterol ester were quantified by high performance liquid chromatography.The hepatic lipase(HL) mRNA expression was determined by RT-PCR.

RESULTS:

(1) Compared with hyperlipid group,the aorta atherosclerosis plaque area and the serum triglyceride level were significantly decreased in sodium ferulate-treated rabbits,but the serum cholesterol level showed little change.(2) Compared with ox-LDL group,the HL mRNA expression in HepG2 cells was enhanced significantly in sodium ferulate-treated group,but the cellular contents of total cholesterol and cholesterol ester in RAW264.7 foam cells showed little change.

CONCLUSION:

Sodium ferulate inhibits the formation of atherosclerotic plaque in high-cholesterol-fed rabbits aorta.This antiatherosclerotic function may reduce serum triglyceride level through enhancing the expression of HL mRNA without influencing serum cholesterol level and foam cell formation.
