Four-hydroxynonenal, a product of lipid peroxidation, is increased in the brain in Alzheimer's disease

Abstract

Recent studies have implicated increased oxidative stress in the pathogenesis of Alzheimer's disease (AD). Increased lipid peroxidation and decreased polyunsaturated fatty acid levels have been described in the brain in AD. Four-hydroxynonenal (HNE), an aldehyde product of lipid peroxidation, has been demonstrated to be a neurotoxin in tissue culture and in vivo studies and is elevated in ventricular fluid in AD. We report here an increase in mean free HNE in multiple brain regions in AD compared with age-matched control subjects. These increases reached statistical significance in the amygdala and hippocampus and parahippocampal gyrus, regions showing the most pronounced histopathological alterations in AD. This study, in conjunction with cell culture studies, suggests that HNE may be an important substance in the pathogenesis of neuron degeneration in AD.

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.
