Oxidative damage to mitochondrial DNA shows marked age-dependent increases in human brain
Abstract
A major theory of aging is that oxidative damage may accumulate in DNA and contribute to physiological changes associated with aging. We examined age-related accumulation of oxidative damage to both nuclear DNA (nDNA) and mitochondrial DNA (mtDNA) in human brain tissue. We measured the oxidized nucleoside, 8-hydroxy-2'-deoxyguanosine (OH8dG), in DNA isolated from 3 regions of cerebral cortex and cerebellum from 10 normal humans aged 42 to 97 years. The amount of OH8dG, expressed as a ratio of the amount of deoxyguanosine (dG) or as fmol/micrograms of DNA, increased progressively with normal aging in both nDNA and mtDNA; however, the rate of increase with age was much greater in mtDNA. There was a significant 10-fold increase in the amount of OH8dG in mtDNA as compared with nDNA in the entire group of samples, and a 15-fold significant increase in patients older than 70 years. These results show for the first time that there is a progressive age-related accumulation in oxidative damage to DNA in human brain, and that the mtDNA is preferentially affected. It is possible that such damage may contribute to age-dependent increases in incidence of neurodegenerative diseases.

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.
