Oxidative stress in aging
WebSep 1, 2024 · Oxidative stress and aging Aging is a dynamic and multi-phase process, during which the characteristics of the cells evolve and diversify continuously about the context ( Boisvert et al., 2024, van Deursen, 2014 ). WebMitochondria are one of the organelles undergoing rapid alteration during the senescence process. Senescent cells show an increase in mitochondrial size, which is attributed to the accumulation of defective mitochondria, which causes mitochondrial oxidative stress. Defective mitochondria are also targets of mitochondrial oxidative stress, and the vicious …
