Abstract:
Even through many physiological pathways of resveratrol have been established since its association with the "French paradox" in 1992, its exact pathological roles are still ambiguous and disputable. To understand how resveratrol exerts its effects would not only enlighten the pathogenesis study of related diseases, but also promote the development of more potent molecules. Focusing on the reported cellular directly and indirectly ROS scavenging processes of resveratrol, we evaluated the activation effect of the inherent antioxidation thiols system in subcellular level by two cysteine (Cys) specific fluorescent probes mitochondria targetable Mito-1 and lysosomes targetable Ly-1. We found that 50 μM resveratrol treatment could induce distinct Cys up-regulation in both mitochondria and lysosomes which might be a general biological phenomenon in various cell lines for the first time.
