Abstract

Young mammals possess a limited regenerative capacity in some tissues, which is lost upon maturation. We investigated whether cellular senescence might play a role in such loss during liver regeneration. We found that following partial hepatectomy, the senescence-associated genes p21, p16 Ink4a , and p19 Arf become dynamically expressed in different cell types when regenerative capacity decreases, but without a full senescent response. However, we show that treatment with a senescence-inhibiting drug improves regeneration, by disrupting aberrantly prolonged p21 expression. This work suggests that senescence may initially develop from heterogeneous cellular responses, and that senotherapeutic drugs might be useful in promoting organ regeneration.

  • Removal of senescent cells by ABT-737 in the liver enhanced liver regeneration in adult mice without cancer.

    “Removal of senescent cells by ABT-737 in the liver also enhanced liver regeneration in adult mice without cancer 211 .”

    The Results and Discussion section, “ABT-737 treatment improves liver regeneration” (page unavailable), reports increased regenerative capacity after ABT-737 pretreatment in 6–8-month-old mice. But “ABT-737 decreases p21 and SASP expression” (page unavailable) reports no detectable increase in apoptosis in treated livers and suggests the drug may instead interfere with p21 and SASP expression. The improvement is supported; attributing it to removal of senescent cells is not established. (LLM, conf=0.88)

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.
