Abstract

Monitoring cancer and aging in vivo remains experimentally challenging. Here, we describe a luciferase knockin mouse (p16(LUC)), which faithfully reports expression of p16(INK4a), a tumor suppressor and aging biomarker. Lifelong assessment of luminescence in p16(+/LUC) mice revealed an exponential increase with aging, which was highly variable in a cohort of contemporaneously housed, syngeneic mice. Expression of p16(INK4a) with aging did not predict cancer development, suggesting that the accumulation of senescent cells is not a principal determinant of cancer-related death. In 14 of 14 tested tumor models, expression of p16(LUC) was focally activated by early neoplastic events, enabling visualization of tumors with sensitivity exceeding other imaging modalities. Activation of p16(INK4a) was noted in the emerging neoplasm and surrounding stromal cells. This work suggests that p16(INK4a) activation is a characteristic of all emerging cancers, making the p16(LUC) allele a sensitive, unbiased reporter of neoplastic transformation.

  • Mouse models of melanoma and human nevi show accumulation of SA-β-gal+-CDKN2A+ foci.

    “Mouse models of melanoma and human nevi (both oncogene driven) show accumulation of SA-β-gal+–CDKN2A+ foci224,225.”

    From SenNet recommendations for detecting senescent cells in different tissues (2024) · cites this paper as [224]

    The Results section (“p16LUC Signals Cancer”; page unavailable) reports focal p16INK4a-promoter activity in an oncogene-driven mouse melanoma model. It does not establish that those foci are SA-β-gal-positive, and the cited paper does not report the claimed foci in human nevi. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • p16 is considered the best marker of senescent cells.

    “p16 is considered the best marker of senescent cells, and its expression is upregulated in many tissues during ageing [10 -12].”

    From The role of cellular senescence and SASP in tumour microenvironment (2023) · cites this paper as [12]

    The Discussion calls p16INK4a expression “one of the best in vivo markers of cellular senescence,” supporting its standing as a strong marker. It does not identify p16 as the single best marker, and it notes that expression can also reflect tissue insults unrelated to senescence. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Ageing is associated with the steady accumulation of senescent cells.

    “Furthermore, as the most important risk factor for cancer, ageing is associated with the steady accumulation of senescent cells [10 -12]”

    From The role of cellular senescence and SASP in tumour microenvironment (2023) · cites this paper as [12]

    The Results section reports a sustained increase in p16INK4a expression with age and describes it as a marker of cellular senescence. The Discussion cautions, however, that this increase may reflect stresses other than senescence, so the paper does not establish a steady accumulation of senescent cells themselves. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Senescent cells accumulate due to various in vivo stresses during aging.

    “Senescent cells have been observed to accumulate due to various in vivo stresses during the aging process (4–6).”
  • p16 expression is upregulated in many tissues during ageing.

    “p16 is considered the best marker of senescent cells, and its expression is upregulated in many tissues during ageing [10 -12].”

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.
