Research Abstract

We selected red wine polyphenol, resveratrol (RSV), among phytochemicals in this study, and analyzed its effects on neurons and hepatocytes in a neurodegeneration-related senescence-accelerated mouse P10 (SAMP10) and rat neuronal cell line (PC12 cells). When treated with RSV, in the SAMP10 degenerative neurons of the brain were significantly recovered, and as expected in the liver hepatocytes were much more improved. We analyzed more direct influence of RSV on the PC12 cell, and have proposed that RSV may promote cell survival by activations of mitochondria and autophagy.
