Molecular mechanism of the chemopreventive effect of resveratrol

Chemoprevention is a promising approach to control human cancer. Resveratrol has been shown to have a potent chemopreventive effect in multiple carcinogenesis models. However, the precise mechanism explaining its anti-carcinogenic effect is not clear. This review summarizes recent studies from our laboratory on the mechanisms of resveratrol's effects. In JB6 cells, resveratrol was found to induce apoptosis and inhibit tumor promoter-induced cell transformation. We also found that resveratrol-induced activation of p53 and resveratrol-induced apoptosis occurred through a p53-dependent pathway. The MAP kinases, ERKs, JNKs, or p38 kinases, are involved in resveratrol-induced activation of p53 and apoptosis. (C) 2002 Elsevier Science B.V All rights reserved.
