양춘사 추출물이 HepG2 세포에서 콜레스테롤 합성에 미치는 효과 = Effects of Amomum Villosum Extracts on Cholesterol Synthesis in HepG2 Cells

다국어 초록 (Multilingual Abstract)

Dried fruits of Amomum villosum Lour. have been used an korean medicine to treat digestive diseases for a long time. It has been reported that Amomum villosum extracts(AVE) have effects for diabetes and steatosis in experimental models. But we did not find the report about the cholesterol synthesis inhibition effects of AVE. The objective of this study is to clarify the inhibitory effect of AVE against oleic acid and glucose-induced hypercholesterolemia in HepG2 cells. The results show that AVE had a significant inhibitory effect against oleic acid and glucose-induced cholesterol accumulation. Those effects seem to be caused by inhibition of AVE on oleic acid and glucose-induced decrease of HMG CoA reductase, which is the rate-limiting enzyme for cholesterol biosynthesis in liver. It is believed that the results of this study can provide basic data for the drug and functional food development of hypercholesterolemia treatments.
