Abstract

8-hydroxy-2'-deoxyguanosine (8-OHdG) or 8-hydroxyguanosine (8-OHG), a product of oxidized DNA or RNA, is a good marker of oxidative cellular damage. In this study, we measured the 8-OHdG/8-OHG levels in the serum and cerebrospinal fluid (CSF) of patients with Parkinson's disease (PD) and multiple system atrophy (MSA). Compared to age-matched controls, the mean levels of serum 8-OHdG/8-OHG were significantly higher in PD (P < 0.0001). Although no gender differences were observed in the controls, the mean values of serum 8-OHdG/8-OHG were significantly higher in female PD cases (P < 0.005) than in male patients. 8-OHdG/8-OHG levels in CSF were also increased significantly in patients with PD and MSA, however, their relative values were generally much lower than those in the serum. Together with previous studies showing increased peripheral 8-OHdG levels in Alzheimer's disease and amyotrophic lateral sclerosis, the data presented here suggest that systemic DNA/RNA oxidation is commonly observed in neurodegenerative diseases. Our results also imply that female patients with PD show higher levels of oxidative stress, which may explain the faster progression of this disease in females.

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.
