Abstract

Cellular senescence, an irreversible growth arrest triggered by a variety of stressors, plays important roles in normal physiology and tumor suppression, but accumulation of senescent cells with age contributes to the functional decline of tissues. Senescent cells undergo dramatic alterations to their chromatin landscape that affect genome accessibility and their transcriptional program. These include the loss of DNA-nuclear lamina interactions, the distension of centromeres, and changes in chromatin composition that can lead to the activation of retrotransposons. Here we discuss these findings, as well as recent advances in microscopy and genomics that have revealed the importance of the higher-order spatial organization of the genome in defining and maintaining the senescent state.

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

  • Replicative senescence shows loss of long-range and gain of short-range interactions within chromosomes, implying that senescence-associated high-order chromatin interactions are stimulus and context dependent.

    “Replicative senescence, on the other hand, showed loss of long-range and gain of short-range interactions within chromosomes (Criscione et al., 2016), implying that the nature of senescence-associated high-order chromatin interactions is stimulus and context dependent (Zirkel et al., 2018).”

    From Cellular Senescence: Defining a Path Forward (2019) · cites this paper as Criscione et al., 2016

    The Changes in chromosome organization section reports a genome-wide increase in short-range contacts in replicatively senescent cells. It does not report a corresponding loss of long-range within-chromosome interactions in those cells. The sentence attributes its broader stimulus-and-context inference to Zirkel et al., not to this source. (LLM, conf=0.85)

  • LINE-1 elements fuel the SASP in addition to triggering genomic instability.

    “Therefore, in addition to triggering genomic instability, these elements fuel the SASP (Criscione et al., 2016).”

    From Cellular Senescence: Defining a Path Forward (2019) · cites this paper as Criscione et al., 2016

    The section on chromatin structure says activated retrotransposons can propagate genomic instability through insertional mutagenesis. The Concluding remarks also link retrotransposition to new DNA damage, but attribute SASP gene activation to super-enhancer remodeling; they do not say LINE-1 elements fuel the SASP. Page numbers were not available in our copy. (LLM, conf=0.88)

  • Pericentromeric regions are highly enriched for lamin-B1-positive regions in human fibroblasts, suggesting hSATII loci might be tethered to the nuclear membrane to prevent expansion and transcription.

    “Pericentromeric regions are highly enriched for lamin-B1-positive regions in human fibroblasts (43), suggesting that the hSATII loci might be tethered to the nuclear membrane to prevent its expansion and transcription (44).”

    From Chromatin conformational changes at human satellite II contribute to the senescence phenotype in the tumor microenvironment (2023) · cites this paper as [44]

    The section on loss of DNA association with the nuclear envelope says the lamina interacts with heterochromatic domains and that loss of lamina components detaches those domains. The section on transcriptional changes says pericentric HSATII distends and becomes accessible in senescent cells. Neither passage establishes that pericentromeric regions are highly enriched for lamin-B1-positive regions in human fibroblasts or proposes that membrane tethering prevents HSATII expansion and transcription. (LLM, conf=0.78)

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.
