Abstract

PAI-1 (plasminogen activator inhibitor-1) is a member of the evolutionarily conserved serine protease inhibitor family and a potent and rapid-acting inhibitor of both of the mammalian plasminogen activators. Organismal homeostasis requires physiological levels of endogenous PAI-1, and increased PAI-1 production guides the onset and progression of numerous human diseases and contributes to the multimorbidity of aging. Both chronological and stress-induced accelerated aging are associated with cellular senescence and accompanied by marked increases in PAI-1 expression in tissues. Recent studies suggest that PAI-1 is not only a marker but also a key mediator of cellular senescence and organismal aging. Here, we review the significance of PAI-1 as a bonafide marker, as well as a critical mediator, of cellular senescence associated with aging and aging-related pathologies.

  • SERPINE1 is a marker of PS hepatocytes and a known mediator of senescence.

    “SERPINE1 by itself is a marker of PS hepatocytes and is a known mediator of senescence.45”

    From Cellular senescence in human liver under normal aging and cancer (2026) · cites this paper as [45]

    The Background and ‘PAI-1 is a key mediator of cellular senescence’ sections describe PAI-1 as a marker and mediator of cellular senescence. They do not establish it as a marker specifically of PS hepatocytes; the marker examples retrieved concern other cell types. Page numbers are unavailable in our copy. (LLM, conf=0.86)

  • SERPINE1, a known senescence marker and SASP factor, was co-expressed with these genes in Module-5.

    “We found that SERPINE1, a known senescence marker and SASP factor, was co-expressed with these genes in Module-5 [73].”
  • SASP markers were elevated at the protein and gene levels in lung tissue from the COVID-19 autopsy case series, including PAI-1.

    “SASP markers were elevated at the protein and gene levels in lung tissue from our COVID-19 autopsy case series, including PAI-1, which is considered both a major marker and mediator of cellular senescence (65).”

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.
