Abstract

It has been hypothesized that Alzheimer's disease (AD) is caused by an accumulation of damage in DNA due to defective DNA-repair (21). Attempts to test this hypothesis by determining the activity of DNA-repair systems in nonneuronal cells from AD patients and controls so far provided conflicting results. An alternative approach is the direct comparison of DNA-damage levels in neuronal tissue of AD patients and controls. In the present study we assayed the level of DNA breaks and alkali-labile sites in cerebral cortex tissue samples from AD patients and controls obtained from rapid autopsies. Our data on 11 AD patients and 8 control subjects indicate an at least two-fold higher level of DNA damage in cortex of AD patients as compared to controls.

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

  • Increased levels of both SSBs and DSBs are documented in AD, HD, PD, and ALS, and their accumulation correlates with important milestones in disease progression.

    “A plethora of studies document increased levels of both SSBs and DSBs in AD, HD, PD, and ALS (Mullaart et al, 1990; Adamec et al, 1999; McKinnon, 2013, 2017; Madabhushi et al, 2014; Alt & Schwer, 2018; Shanbhag et al, 2019; Thadathil et al, 2021), and their accumulation seem to correlate with important milestones in disease progression.”

  • In AD, a two-fold increase in DNA damage has been found in the cortex compared to healthy controls.

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.
