Protein‐Bound Acrolein: A Novel Marker of Oxidative Stress in Alzheimer's Disease
Open accessAbstract
Abstract : Several lines of evidence support the role of oxidative stress, including increased lipid peroxidation, in the pathogenesis of Alzheimer's disease (AD). Lipid peroxidation generates various reactive aldehydes, such as 4‐hydroxynonenal (HNE), which have been detected immunochemically in AD, particularly in neurofibrillary tangels, one of the major diagnostic lesions in AD brains. A recent study demonstrated that acrolein, the most reactive among the α, β‐unsaturated aldehyde products of lipid peroxidation, could be rapidly incorporated into proteins, generating a carbonyl derivative, a marker of oxidative stress to proteins. The current studies used an antibody raised against acrolein‐modified keyhole limpet hemocyanin (KLH) to test whether acrolein modification of proteins occurs in AD. Double immunofluorescence revealed strong acrolein‐KLH immunoreactivity in more than half of all paired helical filament (PHF)‐1‐labeled neurofibrillary tangles in AD cases. Acrolein‐KLH immunoreactivity was also evident in a few neurons lacking PHF‐1‐positive neurofibrillary tangles. Light acrolein‐KLH immunoreactivity occurred in dystrophic neurites surrounding the amyloid‐β core, which itself lacked acrolein‐KLH staining. The pattern of acrolein‐KLH immunostaining was similar to that of HNE. Control brains did not contain any acrolein‐KLH‐immunoreactive structures. The current results suggest that protein‐bound acrolein is a powerful marker of oxidative damage to protein and support the hypothesis that lipid peroxidation and oxidative damage to protein may play a crucial role in the formation of neurofibrillary tangles and to neuronal death 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.
