Reactive oxygen species aging
WebThe generation of reactive oxygen species secondary to normal aerobic metabolism, and exogenous factors, such as UV radiation, is the main cause of skin aging [18,19]. Oxidative damage leads to the upregulation of stress-related factors, such as hypoxia-inducible factors and nuclear factor-kappa B (NF-κB). WebMitochondria-generated reactive oxygen species have been implicated as a common feature that connects aging of organisms and age-related diseases. Efficient elimination …
