DNA methylation rates scale with maximum lifespan across mammals

Published version of a preprint

Abstract

DNA methylation rates have previously been found to broadly correlate with maximum lifespan in mammals, yet no precise relationship has been observed. We developed a statistically robust framework to compare methylation rates at conserved age-related sites across mammals. We found that methylation rates negatively scale with maximum lifespan in both blood and skin. The emergence of explicit scaling suggests that methylation rates are, or are linked to, an evolutionary constraint on maximum lifespan acting across diverse mammalian lineages.

Claims other papers make about this one

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

  • Long-lived animals share enhanced DNA repair, reduced molecular error rates and other processes.

    “Long-lived animals share enhanced DNA repair3,5,9–11, reduced molecular error rates and other processes6,12–14.”
  • Long-living mammals have enhanced repair and reduced error rates in several processes.

    “Long-living mammals have indeed been found to have enhanced repair and reduced error rates in several processes (some of which may not drive aging).”
  • Cellular error rates inverse to mammalian species lifespan include somatic mutations, epigenetic dysregulation, transcription and translation errors.

    “Cellular error rates that have been found to be inverse to mammalian species lifespan include somatic mutations12, epigenetic dysregulation14, transcription and translation errors13.”

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.
