Proteomic identification of HNE-bound proteins in early Alzheimer disease: Insights into the role of lipid peroxidation in the progression of AD

Abstract

Early Alzheimer's disease (EAD) is the intermediary stage between mild cognitive impairment (MCI) and late-stage Alzheimer's disease (AD). The symptoms of EAD mirror the disease advancement between the two phases. Dementia, memory deficits, and cognitive decline are more pronounced as the disease progresses. Oxidative stress in brain is reported in MCI and AD, including lipid peroxidation indexed by protein-bound 4-hydroxy-2-nonenal (HNE). There are limited data regarding the proteomics analysis of brain from subjects with EAD and even less concerning the possible relationship of EAD HNE-modified brain proteins with HNE-modified proteins in MCI and AD. Proteomics was utilized to investigate excessively HNE-bound brain proteins in EAD compared to those in control. These new results provide potentially valuable insight into connecting HNE-bound brain proteins in EAD to those previously identified in MCI and AD, since EAD is a transitional stage between MCI and late-stage AD. In total, six proteins were found to be excessively covalently bound by HNE in EAD inferior parietal lobule (IPL) compared to age-related control brain. These proteins play roles in antioxidant defense (manganese superoxide dismutase), neuronal communication and neurite outgrowth (dihydropyriminidase-related protein 2), and energy metabolism (alpha-enolase, malate dehydrogenase, triosephosphate isomerase, and F1 ATPase, alpha subunit). This study shows that there is an overlap of brain proteins in EAD with previously identified oxidatively modified proteins in MCI and late-stage AD. The results are consistent with the hypothesis that oxidative stress, in particular lipid peroxidation, is an early event in the progression of AD, and is the first to identify in EAD identical brain proteins previously identified as HNE-modified in MCI and late-state AD.

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?

  • MDH is oxidatively modified by HNE in early AD inferior parietal lobule and its carbonylation is induced by Aβ in vitro and in vivo.

    “MDH is oxidatively modified by HNE in early AD inferior parietal lobule (IPL) [55] and its carbonylation is induced by Aβ in vitro and in vivo [63,65,66].”
  • The activities of LDH, aconitase, and ATP synthase are significantly decreased as a result of oxidation.

    “The activities of LDH, aconitase, and ATP synthase are significantly decreased as a result of oxidation [54,55,56,61]”
  • ATP synthase is carbonylated in vivo by Aβ, significantly modified by HNE in MCI hippocampus and IPL, early AD IPL, and late AD IPL, and significantly nitrated in late AD hippocampus.

    “The carbonylation of ATP synthase is induced in vivo by Aβ [73], and it is significantly modified by HNE in MCI hippocampus and IPL [56], early AD IPL [55], and late AD IPL [54] in addition to being significantly nitrated in late AD hippocampus [57].”
  • The activity of MDH is significantly increased.

    “however, the activity of MDH is significantly increased [55].”
  • MnSOD is oxidatively modified by HNE in early AD IPL, resulting in a significant decrease in enzyme activity.

    “MnSOD is oxidatively modified by HNE in early AD IPL, resulting in a significant decrease in enzyme activity [55]”

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.
