Abstract

DNA repair ensures genomic stability to achieve healthy ageing, including cognitive maintenance. Mutations on genes encoding key DNA repair proteins can lead to diseases with accelerated ageing phenotypes. Some of these diseases are xeroderma pigmentosum group A (XPA, caused by mutation of XPA), Cockayne syndrome group A and group B (CSA, CSB, and are caused by mutations of CSA and CSB, respectively), ataxia-telangiectasia (A-T, caused by mutation of ATM), and Werner syndrome (WS, with most cases caused by mutations in WRN). Except for WS, a common trait of the aforementioned progerias is neurodegeneration. Evidence from studies using animal models and patient tissues suggests that the associated DNA repair deficiencies lead to depletion of cellular nicotinamide adenine dinucleotide (NAD+), resulting in impaired mitophagy, accumulation of damaged mitochondria, metabolic derailment, energy deprivation, and finally leading to neuronal dysfunction and loss. Intriguingly, these features are also observed in Alzheimer’s disease (AD), the most common type of dementia affecting more than 50 million individuals worldwide. Further studies on the mechanisms of the DNA repair deficient premature ageing diseases will help to unveil the mystery of ageing and may provide novel therapeutic strategies for AD.

  • DNA repair, Myc targets V1, and oxidative phosphorylation gene sets are linked to cellular damage or stress facilitating the progression of pathogenesis and contributing to neurodegeneration in AD.

    “Conversely, 5xFAD-Dp16 also exhibited greatly decreased NES for several gene sets, including DNA repair, Myc targets V1, and oxidative phosphorylation, all of which are linked to cellular damage or stress facilitating the progression of the pathogenesis and contributing to neurodegeneration in AD48,49,50 (Figures 3A and S3A).”

    From Interferon signaling modulates Down syndrome-associated Alzheimer’s disease pathology in a mouse model (2025) · cites this paper as [48]

    Section 3.5 (AD; page not provided) links impaired DNA repair to AD pathogenesis and describes mitochondrial dysfunction and oxidative stress in AD. The paper does not establish that the named Myc targets V1 or oxidative phosphorylation gene sets contribute to AD neurodegeneration; its mitochondrial findings are broader than that gene-set claim. (LLM, conf=0.86)

    Section 3.5 (AD; page unavailable) links impaired DNA repair and mitochondrial dysfunction to Alzheimer’s disease pathogenesis, supporting part of the background statement for which this review is cited. It does not address Myc targets V1 or report decreased normalized enrichment scores in 5xFAD-Dp16; those scores are presented as the citing paper’s own results in its figures. (LLM, conf=0.83)

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.
