Outline of Final Research Achievements

We showed that serum HDL-cholesterol levels decreased in rats fed ethanol and their HDL changed to free cholesterol-rich particles. The quantitative and qualitative changes in HDL may be associated with the increased mRNA expression of scavenger receptor class B type I, which functions as an HDL receptor in the liver. It was suggested that the increase in SR-BI expression by ethanol intake may work to suppress atherosclerosis through activation of the reverse cholesterol transport system.

Academic Significance and Societal Importance of the Research Achievements

適度な飲酒は動脈硬化のリスク低減に関連し,抗動脈硬化作用の一つにHDL-コレステロールの増加が知られている。しかし,今回のラットの実験ではエタノール摂取により肝臓のHDL受容体の遺伝子発現が増加し,HDL-コレステロールが減少した。HDL受容体の発現増加はコレステロール逆転送系の活性化を引き起こす可能性が考えられ,本研究で得られた成果は動脈硬化の予防・治療法の確立に貢献することが期待される。
