Abstract

We found that several transposable elements were highly active in Drosophila brain during normal aging. In addition, we found that mutations in Drosophila Argonaute 2 (Ago2) resulted in exacerbated transposon expression in the brain, progressive and age-dependent memory impairment, and shortened lifespan. These findings suggest that transposon activation may contribute to age-dependent loss of neuronal function.

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

  • DNA damage-mediated cell death might be a predominant cause of deleterious effects exerted by retrotransposons in flies.

    “DNA damage-mediated cell death104 might thus be a predominant cause of deleterious effects exerted by retrotransposons in flies.”

    From The role of retrotransposable elements in ageing and age-associated diseases (2021) · cites this paper as [104]

    The passage labeled Abstract (page not provided) says transposable-element activation can cause Chk2-mediated DNA damage-induced cell death in the fly germline, and that neuronal Chk2 disruption delays mortality. It also says a causal role for transposable-element-induced DNA damage in neuronal decline remains unproven; it does not establish cell death as the predominant cause of retrotransposons’ deleterious effects in flies.

  • Sample sizes are similar to or greater than those reported in previous publications.

    “Sample sizes are similar to or greater than those reported in previous publications4,5,10.”
  • Age-associated increases in transposable element activation contributing to genomic instability have been noted in yeast, flies, and mammals.

    “studies in yeast, flies and mammals have noted an age-associated increase in the activation of transposable elements, contributing to genomic instability49–51.”
  • With aging, the efficacy of these surveillance systems is reduced, providing a genomic environment in which TEs may become activated and contribute to somatic mutagenesis.

    “with aging, the efficacy of these systems is known to be reduced, providing a genomic environment in which TEs may become activated and contribute to somatic mutagenesis [244, 245]”

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.
