Abstract

Alzheimer disease ( AD ) is a progressive neurodegenerative disorder associated with aging and characterized pathologically by the presence of senile plaques, neurofibrillary tangles, and neurite and synapse loss. Amyloid beta‐peptide (1–42) [Aβ(1–42)], a major component of senile plaques, is neurotoxic and induces oxidative stress in vitro and in vivo . Redox proteomics has been used to identify proteins oxidatively modified by Aβ(1–42) in vitro and in vivo . In this review, we discuss these proteins in the context of those identified to be oxidatively modified in animal models of AD , and human studies including familial AD , pre‐clinical AD ( PCAD ), mild cognitive impairment ( MCI ), early AD , late AD , Down syndrome ( DS ), and DS with AD ( DS / AD ). These redox proteomics studies indicate that Aβ(1–42)‐mediated oxidative stress occurs early in AD pathogenesis and results in altered antioxidant and cellular detoxification defenses, decreased energy yielding metabolism and mitochondrial dysfunction, excitotoxicity, loss of synaptic plasticity and cell structure, neuroinflammation, impaired protein folding and degradation, and altered signal transduction. Improved access to biomarker imaging and the identification of lifestyle interventions or treatments to reduce Aβ production could be beneficial in preventing or delaying the progression of AD . image This article is part of the special issue "Proteomics" .

  • Altered glucose metabolism is associated with Aβ-mediated lipid peroxidation and protein oxidative damage to glycolytic and mitochondrial enzymes, ion-motive ATPases, opening of voltage-gated Ca2+ channels with Ca2+ elevation in endoplasmic reticulum and mitochondria, and consequent neuronal death.

    “evidence was collected for altered glucose metabolism associated with Aβ-mediated lipid peroxidation and protein oxidative damage to glycolytic and mitochondrial enzymes, ion-motive ATPases, the opening of voltage-gated Ca2+ channels with resulting Ca2+ elevation in endoplasmic reticulum and mitochondria, and consequent neuronal death [8,35].”

  • The increased activity of MDH could be a compensatory mechanism in response to oxidative damage of other key energy-related proteins, including glycolytic enzymes.

    “however, the increased activity could be a compensatory mechanism in response to the oxidative damage of other key energy-related proteins including a number of glycolytic enzymes [35].”

    From Mitochondrial Oxidative and Nitrosative Stress and Alzheimer Disease (2020) · cites this paper as [35]

    The “Energy Yielding Metabolism and Mitochondrial Dysfunction” section (page unavailable) reports oxidative modification of several glycolytic enzymes and describes MDH’s role in supporting glycolytic activity. It does not report increased MDH activity or propose that such an increase compensates for oxidative damage to other proteins. (LLM, conf=0.83)

    Experimental — accuracy not yet measured
  • Oxidative modification and decreased activity of several key glycolytic enzymes in MCI and AD brain are consistent with the observed glucose hypometabolism.

    “Oxidative modification and the decreased activity of several key glycolytic enzymes in MCI and AD brain are consistent with the observed glucose hypometabolism [35].”

    From Mitochondrial Oxidative and Nitrosative Stress and Alzheimer Disease (2020) · cites this paper as [35]

    The “Energy Yielding Metabolism and Mitochondrial Dysfunction” section (page unavailable) reports oxidative modification of multiple glycolytic enzymes in MCI and AD brain and documents reduced glucose catabolism during AD progression. It proposes that enzyme oxidation could contribute to hypometabolism, but the cited passages do not establish decreased activity of several glycolytic enzymes in MCI and AD brain. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Evidence that oxidative damage is a critical part of AD pathology and progression is compelling.

    “The evidence for oxidative damage being a critical component of the pathology and progression of AD is compelling8,11,115.”
  • Many of the oxidized proteins identified are mitochondrial proteins involved in metabolism, protein synthesis and folding, ROS scavenging, transport, and apoptosis.

    “Consistent with the hypothesis that both oxidative stress and mitochondrial dysfunction are early events in the progression of AD [12,35,53], many of the oxidized proteins identified are mitochondrial proteins involved in metabolism, protein synthesis and folding, ROS scavenging, transport, and apoptosis (Table 1).”

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.
