Tight linkage between aging and oxidative stress is indicated by the observations that reactive oxygen species generated under various conditions of oxidative stress are able to oxidize nucleic acids, proteins, and lipids and that aging is associated with the accumulation of oxidized forms of cellular constituents, and also by the fact that there is an inverse relationship between the maximum life span of organisms and the age-related accumulation of oxidative damage. Nevertheless, validity of the oxidative stress hypothesis of aging is questioned by (i) the failure to establish a causal relationship between aging and oxidative damage and (ii) lack of a consistent correlation between the accumulation of oxidative damage and aging. The present discussion is focused on the complexity of the aging process and suggests that discrepancies between various studies in this area are likely due to the fact that aging is not a single process and that the lack of consistent experimental results is partly explained by individual variations. Even so, there is overwhelming support for a dominant role of oxidative stress in the aging of some individuals.
