Roles of chromatin and genome instability in cellular senescence and their relevance to ageing and related diseases

Wu, Zeming, Qu, Jing, Liu, Guang-Hui·2024·Nature Reviews Molecular Cell Biology

Abstract

Ageing is a complex biological process in which a gradual decline in physiological fitness increases susceptibility to diseases such as neurodegenerative disorders and cancer. Cellular senescence, a state of irreversible cell-growth arrest accompanied by functional deterioration, has emerged as a pivotal driver of ageing. In this Review, we discuss how heterochromatin loss, telomere attrition and DNA damage contribute to cellular senescence, ageing and age-related diseases by eliciting genome instability, innate immunity and inflammation. We also discuss how emerging therapeutic strategies could restore heterochromatin stability, maintain telomere integrity and boost the DNA repair capacity, and thus counteract cellular senescence and ageing-associated pathologies. Finally, we outline current research challenges and future directions aimed at better comprehending and delaying ageing.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • IgG induces senescence in macrophages derived from bone marrow, spleen, and peritoneal cavity, as indicated by increased SA-β-Gal activity, P21 expression, upregulated MMTV-positive cells, aggresome formation, and decreased H3K9me3 and lamin B1 levels.

    “Our data revealed that IgG induced senescence in these macrophages, as indicated by an increase in SA-β-Gal activity and P21 expression, along with upregulated MMTV-positive cells, aggresome formation, and decreased H3K9me3 and lamin B1 levels46”

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.
