Abstract

Alcohol use disorder (AUD) screening frequently involves questionnaires complemented by laboratory work to monitor alcohol use and/or evaluate AUD-associated complications. Here we suggest that measuring aldehyde-induced DNA and protein adducts produced during alcohol metabolism may lead to earlier detection of AUD and AUD-associated complications compared with existing biomarkers. Use of aldehyde-induced adducts to monitor AUD may also be important when considering that approximately 540 million people bear a genetic variant of aldehyde dehydrogenase 2 (ALDH2) predisposing this population to aldehyde-induced toxicity with alcohol use. We posit that measuring aldehyde-induced adducts may provide a means to improve precision medicine approaches, taking into account lifestyle choices and genetics to evaluate AUD and AUD-associated complications.

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

  • AA-protein adducts are widely present in the brains of alcohol-exposed rodents or people with AUD; after alcohol consumption they are rapidly produced in the cerebral cortex primarily with mitochondrial proteins and localized in white matter, deep layers of the frontal cortex, and molecular layer of the cerebellum; they also form AA-tubulin adducts causing microtubule malformation and cytoskeletal

    “AA-protein adducts are widely present in the brains of alcohol-exposed rodents or people with alcohol use disorder (AUD)189–192.”
  • Acetaldehyde in the brain alters DNA integrity and neuronal viability; it can form AA-DNA adducts in the brain and peripheral blood leukocytes of people with AUD since ethanol, acetaldehyde, and lipid aldehydes such as MDA and 4-HNE can inhibit DNA repair enzymes; dual mechanisms of elevated AA-DNA adducts and suppressed DNA repair may contribute to genetic instability and DNA mutations, promoting

    “The presence of acetaldehyde in the brain also alters DNA integrity and neuronal viability.”

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.
