Cytotoxic reactive oxygen species
WebThe anticancer therapy on the basis of reactive oxygen species (ROS)-mediated cellular apoptosis has achieved great progress. However, this kind of theraputic strategy still … WebReactive oxygen species (ROS) are the by-products of normal cellular oxidative processes, and are mainly generated in the mitochondria. They attack lipid membranes, proteins, and DNA, leading to serious cell damage, and regulate apoptotic signal transduction [ 1 – 3 ].
