Abstract

Alzheimer's disease (AD) is an age-related neurodegenerative disorder. Although an accumulation of brain amyloid-β (Aβ) peptide and hyperphosphorylated tau protein have been implicated in the pathogenesis of AD, the etiology of the disease remains unclear. Mitochondrial dysfunction has been identified as an early event in AD pathogenesis and is reflected by reduced metabolism, disruption of Ca 2+ homeostasis, and increased levels of reactive oxygen species, lipid peroxidation, and apoptosis. The focus of this review is the involvement of mitochondrial dysfunction in AD, and specifically, the role of the voltage-dependent anion channel 1 (VDAC1), which has been linked to AD pathogenesis. VDAC1 is a multi-functional protein, expressed in the mitochondria and other cell compartments, including the plasma membrane. The protein regulates the main metabolic and energetic functions of the cell, including Ca 2+ homeostasis, oxidative stress, and mitochondria-mediated apoptosis. VDAC1 represents a hub protein that interacts with over 150 other proteins including phosphorylated tau, Aβ, and γ-secretase, and participates in their toxicity. The high levels of VDAC1 demonstrated post-mortem in the brains of AD patients and in amyloid precursor protein (APP) transgenic mice prompted the hypothesis that the protein may be associated with neuronal cell destruction since over-expression of VDAC1 triggers cell death. Thus, targeting mitochondrial dysfunction via VDAC1, to prevent this pro-apoptotic activity, could represent a novel strategy for inhibiting cell death. In addition, the review also discusses possible VDAC1 involvement in the link between AD and diabetes and the inverse association between cancer and 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?

  • VDAC1, located in the outer mitochondrial membrane, regulates mitochondrial membrane permeability.

    “The voltage-dependent anion channel 1 (VDAC1), located in the outer mitochondrial membrane, regulates mitochondrial membrane permeability [94]”
  • A dynamic equilibrium between monomeric and oligomeric states of VDAC1 exists, with the oligomeric state formed upon apoptotic induction resulting in a channel through which cytochrome c efflux can occur.

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.
