Protein Oxidation in Aging and Age‐Related Diseases

Stadtman, Earl R.·2001·Annals of the New York Academy of Sciences

Abstract

Although different theories have been proposed to explain the aging process, it is generally agreed that there is a correlation between aging and the accumulation of oxidatively damaged proteins, lipids, and nucleic acids. Oxidatively modified proteins have been shown to increase as a function of age. Studies reveal an age-related increase in the level of protein carbonyl content, oxidized methionine, protein hydrophobicity, and cross-linked and glycated proteins as well as the accumulation of less active enzymes that are more susceptible to heat inactivation and proteolytic degredation. Factors that decelerate protein oxidation also increase the life span of animals and vice versa. Furthermore, a number of age-related diseases have been shown to be associated with elevated levels of oxidatively modified proteins. The chemistry of reactive oxygen species-mediated protein modification will be discussed. The accumulation of oxidatively modified proteins may reflect deficiencies in one or more parameters of a complex function that maintains a delicate balance between the presence of a multiplicity of prooxidants, antioxidants, and repair, replacement, or elimination of biologically damaged proteins.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
