Abstract

Perturbed neuronal Ca(2+) homeostasis is implicated in age-related cognitive impairment and Alzheimer's disease (AD). With advancing age, neurons encounter increased oxidative stress and impaired energy metabolism, which compromise the function of proteins that control membrane excitability and subcellular Ca(2+) dynamics. Toxic forms of amyloid beta-peptide (Abeta) can induce Ca(2+) influx into neurons by inducing membrane-associated oxidative stress or by forming an oligomeric pore in the membrane, thereby rendering neurons vulnerable to excitotoxicity and apoptosis. AD-causing mutations in the beta-amyloid precursor protein and presenilins can compromise these normal proteins in the plasma membrane and endoplasmic reticulum, respectively. Emerging knowledge of the actions of Ca(2+) upstream and downstream of Abeta provides opportunities to develop novel preventative and therapeutic interventions for AD.

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

  • Glucose metabolism is significantly impaired in Alzheimer disease and amnestic mild cognitive impairment brains.

    “Yet glucose metabolism in AD and aMCI brains is significantly impaired5–7,9,38.”

    From Oxidative stress, dysfunctional glucose metabolism and Alzheimer disease (2019) · cites this paper as [38]

    The section ‘Amyloid β-Peptide Promotes Ca2+ Influx and Ca2+-Mediated Excitotoxicity’ says Aβ-related damage impairs neuronal glucose transporters, supporting a connection between AD pathology and impaired glucose handling. The paper does not report significantly impaired brain glucose metabolism in both AD and amnestic mild cognitive impairment; its ‘Synapses: the Weakest Link’ section discusses MCI in relation to synaptic dysfunction instead. Page numbers are unavailable in our copy. (LLM, conf=0.84)

  • Aβ may increase cytosolic calcium levels and impair mitochondrial calcium buffering functions through plasma membrane receptors and calcium channels, enhanced ER calcium release, and the mitochondrial inner membrane calcium channel MCU, leading to mitochondrial calcium overload, CypD relocation, mPTP formation, inhibition of ATP synthesis, and activation of oxidative stress and apoptosis.

    “Aβ may increase cytosolic calcium levels and impair mitochondrial calcium buffering functions through various pathways including plasma membrane receptors and calcium channels,291 enhanced ER calcium release,292 and the mitochondrial inner membrane calcium channel MCU.293,294 This leads to mitochondrial calcium overload, causing cyclophilin D (CypD) to relocate from the mitochondrial matrix to the”

  • Glucose metabolism is markedly reduced in Alzheimer disease and amnestic mild cognitive impairment.

    “in AD and amnestic mild cognitive impairment (aMCI) glucose metabolism is dramatically decreased”

    From Oxidative stress, dysfunctional glucose metabolism and Alzheimer disease (2019) · cites this paper as [38]

    The section ‘Amyloid β-Peptide Promotes Ca2+ Influx and Ca2+-Mediated Excitotoxicity’ describes impaired glucose transporters, while ‘Synapses: the Weakest Link’ discusses patients with mild cognitive impairment and AD. Neither reports that glucose metabolism is markedly reduced in AD and amnestic mild cognitive impairment; searches for those terms found no such passage. Page numbers were unavailable in our copy. (LLM, conf=0.72)

    Experimental — accuracy not yet measured
  • Mitochondrial dysfunction and insulin resistance are closely related.

    “Indeed, mitochondrial dysfunction and insulin resistance are intimately related7,38.”

    From Oxidative stress, dysfunctional glucose metabolism and Alzheimer disease (2019) · cites this paper as [38]

    The “Calcium Stability in the Face of Adversity” box discusses impaired mitochondrial calcium handling in Alzheimer’s disease, but does not connect it to insulin resistance. Searches of our full-text copy for “insulin resistance” and “insulin” found no passage addressing that relationship; page numbers were not available. (LLM, conf=0.73)

  • Brain insulin resistance is common in Alzheimer disease.

    “Brain insulin resistance is common in AD7,38,41.”

    From Oxidative stress, dysfunctional glucose metabolism and Alzheimer disease (2019) · cites this paper as [38]

    The Abstract and the section on neuronal Ca2+ signaling discuss calcium dysregulation and impaired energy metabolism in Alzheimer’s disease, not brain insulin resistance. Searches for “brain insulin resistance,” “insulin signaling,” and “insulin” found no passage stating that insulin resistance is common in AD. (LLM, conf=0.76)

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.
