title: Resveratrol exerts pharmacological preconditioning by activating PGC-1alpha.
abstract: Resveratrol (RSV), a polyphenol phytoalexin abundantly found in grape skins and in wines, is currently the focus of intense research as a pharmacological preconditioning agent in kidney, heart, and brain from ischemic injury. However, the exact molecular mechanism of RSV preconditioning remains obscure. The data from current studies indicate that pharmacological preconditioning with RSV were attributed to its role as intracellular antioxidant, anti-inflammatory agent, its ability to induce nitric oxide synthase (NOS) expression, its ability to induce angiogenesis, and its ability to increases sirtuin 1 (SIRT1) activity. Peroxisome proliferators-activated receptor (PPAR) gamma co-activator-1alpha (PGC-1alpha) is a member of a family of transcription coactivators that owns mitochondrial biogenesis, antioxidation, growth factor signaling regulation, and angiogenesis activities. And, almost all the signaling pathways activated by RVS involve in PGC-1alpha activity. Moreover, it has been proofed that RVS could mediate an increase PGC-1alpha activity. These significant conditions support the hypothesis that RSV exerts pharmacological preconditioning by activating PGC-1alpha. Attempts to confirm this hypothesis will provide new directions in the study of pharmaceutical preconditioning and the development of new treatment approaches for reducing the extent of ischemia/reperfusion injury.
