摘要：

The effect of epicatechin-3-gallate (ECG), a polyphenol that is present in green tea, on doxorubicin (DOX) cytotoxicity in H9C2 cardiomyocytes and its underlying mechanisms were investigated. Pretreatment with ECG (20 and 30 mu M) significantly increased DOX-induced apoptosis to 16-18 % in H9C2 cardiomyocytes. The Bax/Bcl-2 ratio increased significantly after 1 h pretreatment with ECG. ECG also enhanced the phosphorylation of AMP-activated protein kinase (AMPK) which was induced by DOX in a dose-dependent manner. Pretreatment with ECG sensitized H9C2 cells to DOX-mediated apoptosis through modulation of proteins involved in apoptosis and AMPK.
