title: Resveratrol regulates gene transcription via activation of stimulus-responsive transcription factors.
abstract: Resveratrol (trans-3,4',5-trihydroxystilbene), a polyphenolic phytoalexin of grapes and other fruits and plants, is a common constituent of our diet and of dietary supplements. Many health-promoting benefits have been connected with resveratrol in the treatment of cardiovascular diseases, cancer, diabetes, inflammation, neurodegeneration, and diseases connected with aging. To explain the pleiotropic effects of resveratrol, the molecular targets of this compound have to be identified on the cellular level. Resveratrol induces intracellular signal transduction pathways which ultimately lead to changes in the gene expression pattern of the cells. Here, we review the effect of resveratrol on the activation of the stimulus-responsive transcription factors CREB, AP-1, Egr-1, Elk-1, and Nrf2. Following activation, these transcription factors induce transcription of delayed response genes. The gene products of these delayed response genes are ultimately responsible for the changes in the biochemistry and physiology of resveratrol-treated cells. The activation of stimulus-responsive transcription factors may explain many of the intracellular activities of resveratrol. However, results obtained in vitro may not easily be transferred to in vivo systems.
