Abstract

The p53 tumor suppressor can restrict malignant transformation by triggering cell-autonomous programs of cell-cycle arrest or apoptosis. p53 also promotes cellular senescence, a tumor-suppressive program that involves stable cell-cycle arrest and secretion of factors that modify the tissue microenvironment. In the presence of chronic liver damage, we show that ablation of a p53-dependent senescence program in hepatic stellate cells increases liver fibrosis and cirrhosis associated with reduced survival and enhances the transformation of adjacent epithelial cells into hepatocellular carcinoma. p53-expressing senescent stellate cells release factors that skew macrophage polarization toward a tumor-inhibiting M1-state capable of attacking senescent cells in culture, whereas proliferating p53-deficient stellate cells secrete factors that stimulate polarization of macrophages into a tumor-promoting M2-state and enhance the proliferation of premalignant cells. Hence, p53 can act non-cell autonomously to suppress tumorigenesis by promoting an antitumor microenvironment, in part, through secreted factors that modulate macrophage function.

  • This immune response is mediated by SASP components and by direct contact between immune cells and senescent cells.

    “This response is mediated by SASP components and by the direct interaction between immune cells and senescent cells153,156–158.”

    From Cellular senescence in ageing: from mechanisms to therapeutic opportunities (2021) · cites this paper as [153]

    The Results sections on SASP and macrophage function show that SASP factors affect macrophage targeting of senescent hepatic stellate cells. The co-culture experiments show macrophages eliminating those cells, but do not establish that direct cell-to-cell contact mediates the response. Page numbers are unavailable in our copy.

  • The SASP of senescent hepatic stellate cells participates in fibrotic scar degradation and restores tissue homeostasis in liver fibrosis.

    “Senescent fibroblasts contribute to wound healing (Demaria et al. 2014), and the SASP of senescent hepatic stellate cells (HSCs) participates in fibrotic scar degradation and restores tissue homeostasis in liver fibrosis (Lujambio et al. 2013).”

    From Senescence and the SASP: many therapeutic avenues (2020) · cites this paper as Lujambio et al. 2013

    The Introduction describes senescent HSCs as part of a tissue-homeostatic mechanism that limits fibrosis and facilitates its resolution, including through SASP effects on the extracellular matrix and immune surveillance. The Discussion says HSC p53 activity helps maintain organ integrity through SASP. Neither passage establishes fibrotic-scar degradation specifically or shows that tissue homeostasis is restored, so the claim overstates those outcomes. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • The senescence-associated phenotype identified with secretion of pro-tumorigenic cytokines and chemokines can be restrained or qualitatively modified by p53 in several cell types in mouse.

    “This senescence-associated phenotype identified with secretion of pro-tumorigenic cytokines and chemokines can be restrained or qualitatively modified by p53 in several cell types in mouse [39, 41].”

    From Ligand dependent restoration of human TLR3 signaling and death in p53 mutant cells (2016) · cites this paper as [41]

    The Results and Discussion report that p53 qualitatively changes cytokine and chemokine secretion in murine hepatic stellate cells, promoting an anti-tumorigenic microenvironment. The Discussion also mentions an earlier report of p53 suppressing secretion in senescent fibroblasts, but this paper does not establish the claimed effect in several mouse cell types. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Senescent cells are surveilled by several innate and adaptive immune cell types, including NK cells, T cells, and macrophages.

    “Senescent cells are indeed subjected to immunosurveillance by multiple components of innate and adaptive immunity, including NK cells, T cells and macrophages145,151,153–156.”
  • In a fibrosis-associated liver cancer model, the SASP can contribute to an anti-tumor microenvironment by skewing macrophage polarization to a tumor-inhibiting M1 state.

    “Moreover, in a fibrosis-associated liver cancer model, the SASP can contribute to an anti-tumor microenvironment by skewing macrophage polarization to a tumor-inhibiting M1 state (Lujambio et al. 2013).”

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.
