Abstract

Senescence, a persistent form of cell-cycle arrest, is often associated with a diverse secretome, which provides complex functionality for senescent cells within the tissue microenvironment. We show that oncogene-induced senescence is accompanied by a dynamic fluctuation of NOTCH1 activity, which drives a TGF-β-rich secretome, while suppressing the senescence-associated pro-inflammatory secretome through inhibition of C/EBPβ. NOTCH1 and NOTCH1-driven TGF-β contribute to 'lateral induction of senescence' through a juxtacrine NOTCH-JAG1 pathway. In addition, NOTCH1 inhibition during senescence facilitates upregulation of pro-inflammatory cytokines, promoting lymphocyte recruitment and senescence surveillance in vivo. As enforced activation of NOTCH1 signalling confers a near mutually exclusive secretory profile compared with typical senescence, our data collectively indicate that the dynamic alteration of NOTCH1 activity during senescence dictates a functional balance between these two distinct secretomes: one representing TGF-β and the other pro-inflammatory cytokines, highlighting that NOTCH1 is a temporospatial controller of secretome composition.

  • In deeply senescent cells NOTCH1 is lower and the proinflammatory SASP cytokines IL-1, IL-6 and IL-8 are induced.

    “At later stages, in deeply senescent cells, NOTCH1 levels are lower, and the SASP proinflammatory cytokines IL-1, IL-6 and IL-8 are induced94.”

    From Cellular senescence in ageing: from mechanisms to therapeutic opportunities (2021) · cites this paper as [94]

    In Results, “NOTCH1 signalling is dynamically regulated during senescence” (page unavailable), active NOTCH1 signalling returns near basal levels at full senescence, and IL-6 and IL-8 are primarily upregulated then. But cell-surface NOTCH1 continually increases rather than becoming lower. The paper identifies IL-1 as a proinflammatory SASP component, but the cited passage does not establish that IL-1 is induced specifically at full senescence. (LLM, conf=0.90)

  • NF-κB and C/EBPβ bind promoters of SASP genes and regulate their activation.

    “NF-κB and the transcription factor CCAAT/enhancer-binding protein-β (C/EBPβ) bind promoters of SASP genes and regulate their activation74,93,94”

    From Cellular senescence in ageing: from mechanisms to therapeutic opportunities (2021) · cites this paper as [94]

    In Results (“NOTCH1 regulates senescence secretome through repression of C/EBPβ”; page not provided), the paper reports C/EBPβ binding at the IL1A, IL6 and IL8 promoters and links it to cytokine expression. It also says NF-κB cooperatively regulates the SASP, but does not establish that NF-κB binds SASP-gene promoters. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Notch1 in oncogene-induced senescence and DPP4 in replicative and oncogene-induced senescence are upregulated cell surface markers.

    “Recently, two additional upregulated cell surface markers, Notch1 in OIS and DPP4 in replicative and OIS, were identified (Hoare et al., 2016).”

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

    The Results section, “NOTCH1 is upregulated in OIS” (page unavailable), reports substantial upregulation of cell-surface NOTCH1 during oncogene-induced senescence. Our copy does not report DPP4 as an upregulated marker in replicative or oncogene-induced senescence; searches for DPP4 and CD26 found no supporting passage. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Notch1 and DPP4 have roles in regulating the SASP.

    “Both proteins have roles in regulating the SASP.”

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

    The Introduction and Results section on NOTCH1’s regulation of TGF-β and pro-inflammatory cytokines show that NOTCH1 regulates SASP composition. Our copy does not establish a SASP-regulating role for DPP4; searches for DPP4 and dipeptidyl peptidase 4 found no supporting passage. Page numbers were not available in the indexed passages. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • In OIS, fluctuations in NOTCH1 levels switch an early TGF-β-rich immunosuppressive secretome to a proinflammatory SASP.

    “In OIS, fluctuations in NOTCH1 levels switch an early TGF-β-rich immunosuppressive secretome to a proinflammatory SASP (Hoare et al. 2016).”

    From Senescence and the SASP: many therapeutic avenues (2020) · cites this paper as Hoare et al. 2016

    The Results sections on dynamic NOTCH1 signalling and reciprocal secretome regulation (pages unavailable) support an early TGF-β-rich phase followed by a pro-inflammatory phase in oncogene-induced senescence. The immune-clearance Results show that NOTCH1-regulated secretions reduce lymphocyte adhesion, but do not establish that the early TGF-β-rich secretome itself is broadly immunosuppressive. The paper also distinguishes fluctuating NOTCH1 activity from cell-surface NOTCH1 levels, which continued to rise. (LLM, conf=0.84)

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.
