Abstract

We used a collection of 708 prospectively collected autopsied brains to assess the methylation state of the brain's DNA in relation to Alzheimer's disease (AD). We found that the level of methylation at 71 of the 415,848 interrogated CpGs was significantly associated with the burden of AD pathology, including CpGs in the ABCA7 and BIN1 regions, which harbor known AD susceptibility variants. We validated 11 of the differentially methylated regions in an independent set of 117 subjects. Furthermore, we functionally validated these CpG associations and identified the nearby genes whose RNA expression was altered in AD: ANK1, CDH23, DIP2A, RHBDF2, RPL13, SERPINF1 and SERPINF2. Our analyses suggest that these DNA methylation changes may have a role in the onset of AD given that we observed them in presymptomatic subjects and that six of the validated genes connect to a known AD susceptibility gene network.

  • Alterations in DNA methylation levels are involved in many diseases, including AD.

    “Alterations of DNA methylation levels have been shown to be involved in many diseases, including AD [19–24].”

    From Distinct sex-specific DNA methylation differences in Alzheimer’s disease (2022) · cites this paper as [19]

    The Discussion reports replicated associations between altered DNA methylation and AD pathology, supporting the AD portion of the claim. It says the changes suggest a role in AD onset but explicitly cautions that the study cannot establish whether they contribute to the disease or are an early consequence of it. Thus, 'shown to be involved' is stronger than the source establishes. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • DNA methylation is an important epigenetic modification that regulates gene transcription and is involved in Alzheimer's disease.

    “DNA methylation is an important epigenetic modification that regulates gene transcription and is known to be involved in AD”

    From Sex-specific DNA methylation differences in Alzheimer’s disease pathology (2021) · cites this paper as [18]

    The Introduction reports altered DNA methylation at 71 CpGs associated with AD pathology and says transcription of genes in those regions is independently associated with AD pathology. This supports a link between methylation, transcription and AD, but does not establish that the observed methylation changes regulate transcription; the section on cognitively non-impaired subjects says whether they contribute to the disease process remains open. Page numbers were not supplied in our copy. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Consistent with previous studies, we observed the majority of these sex-specific differences were hyper-methylated in samples with AD neuropathology, for which methylation levels increased as the AD Braak stage increased.

    “Consistent with previous studies [18, 19, 86, 87], we observed the majority of these sex-specific differences were hyper-methylated in samples with AD neuropathology, for which methylation levels increased as the AD Braak stage increased”

    From Sex-specific DNA methylation differences in Alzheimer’s disease pathology (2021) · cites this paper as [18]

    In ‘Discovery study to identify differentially methylated chromosomal regions’ (page unavailable), the paper reports that 82% of its differentially methylated regions were more methylated in subjects with a neuropathologic AD diagnosis. ‘Validation of the associated CpG in an independent sample set’ (page unavailable) reports associations using Braak staging, but does not establish that methylation increased with each successive stage. The paper does not identify the citing authors’ sex-specific differences as the regions it studied. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Dysregulated DNA methylation is an early feature of AD neuropathology in the brain.

    “dysregulated DNAm has been observed as an early feature of AD neuropathology in the brain [19]”
  • Alterations of DNA methylation levels have been implicated in multiple neurological disorders including AD.

    “Importantly, alterations of DNA methylation levels have also been implicated in multiple neurological disorders including AD [18–22]”

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.
