Abstract

Transcriptional control of cell senescence: Senescent cells that have stopped proliferating secrete molecules that influence the cells around them. Prevention of this senescence-activated secretory phenotype seems to slow organismal aging. Kang et al. explored the regulatory process behind cell senescence and found that DNA damage led to stabilization of the transcription factor GATA4 (see the Perspective by Cassidy and Narita). Increased activity of GATA4 in senescent cells stimulated genes encoding secreted factors. GATA4 also accumulates in the brains of aging mice or humans.

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

  • GATA4 acts as a molecular link between DDR signalling and subsequent NF-κB activation for full SASP establishment, although its regulation of NF-κB is indirect through increased IL-1α expression and secretion.

    “Because GATA4 levels increase following DDR activation and in senescent cells, it was proposed that GATA4 acts as the molecular link between DDR signalling and the subsequent NF-κB activation for full SASP establishment95,96, although GATA4 regulation of the NF-κB pathway happens indirectly through increased expression and secretion of IL-1α, an upstream regulator of NF-κB97”

    From Cellular senescence in ageing: from mechanisms to therapeutic opportunities (2021) · cites this paper as [95]

    The sections ‘GATA4, a new branch of the senescence regulatory pathway’ and ‘GATA4 regulates NF-κB’ place GATA4 downstream of DDR signalling and upstream of NF-κB in SASP regulation. The latter section identifies IL1A as one mediator, but also identifies TRAF3IP2; it does not specifically show increased IL1A secretion. Page numbers are unavailable in our copy. (LLM, conf=0.85)

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.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-04.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-04.

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.
