Abstract

Oxidative stress has been implicated in the pathogenesis of Alzheimer's disease (AD). Both AD and arguably its earlier form, mild cognitive impairment (MCI), have elevated membrane oxidative damage in brain. The tumor suppressor and transcription factor p53 plays a pivotal function in neuronal apoptosis triggered by oxidative stress. Apoptosis contributes to neuronal death in many neurological disorders, including AD. In this study, we investigated p53 expression in a specific region of the cerebral cortex, namely the inferior parietal lobule (IPL), in MCI and AD brain, to test the hypothesis that alterations of this pro‐apoptotic protein may be involved in neuronal death in the progression of AD. By immunoprecipitation assay, we also investigated whether 4‐hydroxy‐2‐transnonenal (HNE), an aldehydic product of lipid peroxidation, was bound in excess to p53 in IPL from subjects with MCI and AD compared to control. Overall, the data provide evidence that p53 is involved in the neuronal death in both MCI and AD, suggesting that the observed alterations are early events in the progression of AD. In addition, HNE may be a novel non‐protein mediator of oxidative stress‐induced neuronal apoptosis.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • p53 is significantly modified by carbonylation, but not 3NT or HNE in MCI IPL.

    “p53 is significantly modified by carbonylation, but not 3NT or HNE in MCI IPL [87,88].”

    From Mitochondrial Oxidative and Nitrosative Stress and Alzheimer Disease (2020) · cites this paper as [88]

    The Results and discussion section (page unavailable) reports no significant difference in HNE bound to p53 in MCI inferior parietal lobule (IPL), supporting the HNE portion of the claim. It reports increased p53 levels in MCI IPL, but does not report significant p53 carbonylation or a 3NT result; increased protein level is not evidence of those modifications. (LLM, conf=0.90)

    Experimental — accuracy not yet measured
  • p53 is significantly increased in MCI and AD IPL with p53 significantly modified by protein-bound HNE, 3-NT, and carbonyls in an AD brain.

    “p53 is significantly increased in MCI and AD IPL with p53 significantly modified by protein-bound HNE, 3-NT, and carbonyls in an AD brain.”

    From Mitochondrial Oxidative and Nitrosative Stress and Alzheimer Disease (2020) · cites this paper as [88]

    The Results and discussion report significantly increased p53 levels in MCI and AD inferior parietal lobule (IPL), and significantly increased HNE binding to p53 in AD IPL. Our copy does not report that p53 was significantly modified by 3-NT or carbonyls in AD brain; searches for those terms found no such result. No page number was provided in the indexed copy. (LLM, conf=0.90)

    Experimental — accuracy not yet measured
  • Increased p38MAPK activity is present in AD brains and lymphocytes and in the cortex of a mouse model of AD.

    “Increased p38MAPK activity has been reported in AD brains and lymphocytes [205,206,207,208], as well as in the cortex of a mouse model of AD [209].”

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.
