Oxidative Stress and Cell Signalling

An increasing body of evidence from animal models, human specimens and cell lines points to reactive oxygen species as likely involved in the pathways, which convey both extracellular and intracellular signals to the nucleus, under a variety of pathophysiological conditions. Indeed, reactive oxygen species (ROS), in a concentration compatible with that detectable in human pathophysiology, appear able to modulate a number of kinases and phosphatases, redox sensitive transcription factors and genes. This type of cell signalling consistently implies the additional involvement of other bioactive molecules that stem from ROS reaction with cell membrane lipids. The present review aims to comprehensively report on…
