Resveratrol, one of polyphenols derived from red wine, has been shown to protect against cell death, possibly through the association with several signaling pathways. Currently numerous studies indicate that cardiovascular diseases are linked to the release of intracellular reactive oxygen species (ROS) often generated in states such as ischemia/reperfusion injury. In the present study, we investigated whether resveratrol has the capability to control intracellular survival signaling cascades involving AMP-activated kinase (AMPK) in the inhibitory process of cardiac injury. We hypothesized that resveratrol may exert a protective effect on damage to heart muscle through modulating of the AMPK signaling pathway. We mimicked ischemic conditions by inducing cell death with H(2)O(2) in H9c2 muscle cells. In this experiment, resveratrol induced strong activation of AMPK and inhibited the occurrence of cell death caused by treatment with H(2)O(2). Under the same conditions, inhibition of AMPK using dominant negative AMPK constructs dramatically abolished the effect of resveratrol on cell survival in H(2)O(2)-treated cardiac muscle cells. These results indicate that resveratrol-induced cell survival is mediated by AMPK in H9c2 cells and may exert a novel therapeutic effect on oxidative stress induced in cardiac disorders.
