Abstract

Senescent cells accumulate in many tissues as animals age and are considered to underlie several aging-associated pathologies. The tumor suppressors p19 ARF and p16 INK4a , both of which are encoded in the CDKN2A locus, play critical roles in inducing and maintaining permanent cell cycle arrest during cellular senescence. Although the elimination of p16 INK4a -expressing cells extends the life span of the mouse, it is unclear whether tissue function is restored by the elimination of senescent cells in aged animals and whether and how p19 ARF contributes to tissue aging. The aging-associated decline in lung function is characterized by an increase in compliance as well as pathogenic susceptibility to pulmonary diseases. We herein demonstrated that pulmonary function in 12-month-old mice was reversibly restored by the elimination of p19 ARF -expressing cells. The ablation of p19 ARF -expressing cells using a toxin receptor-mediated cell knockout system ameliorated aging-associated lung hypofunction. Furthermore, the aging-associated gene expression profile was reversed after the elimination of p19 ARF . Our results indicate that the aging-associated decline in lung function was, at least partly, attributed to p19 ARF and was recovered by eliminating p19 ARF -expressing cells.

  • Cellular senescence is a central mechanism contributing to IPF.

    “Converging evidence suggests that the aging hallmark, cellular senescence, may be a central mechanism contributing to IPF [6,7].”

    From Senolytics in idiopathic pulmonary fibrosis: Results from a first-in-human, open-label, pilot study (2019) · cites this paper as [7]

    The Results describe senescence in alveolar fibroblasts of aging mice, and the discussion links senescent cells to age-related changes in lung function. The cited paper does not address idiopathic pulmonary fibrosis (IPF) or establish senescence as a central mechanism contributing to it; its disease discussion instead concerns COPD and emphysema. Page numbers were not available in our copy. (LLM, conf=0.80)

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.
