WebNov 6, 2010 · Abstract The free radical theory of aging proposes a causal relationship between reactive oxygen species (ROS) and aging. While it is clear that oxidative damage increases with age, its role in the aging process is uncertain. Testing the free radical theory of aging requires experimentally manipulating ROS production or detoxification and … WebHowever, ROS have also been shown to function as signaling molecules. 8 This underlies relevant mechanisms that are essential for the integrity of living organisms and their aging process. Knowledge of the pathways that regulate ROS homeostasis is pivotal for relieving the deleterious effects of ROS in cells and tissues.
