Abstract

Significance: In response to a variety of stress signals, tumor suppressor p53 is activated to influence the cellular outcome. Various stresses result in different levels of p53 activation. We demonstrate here that during mouse development, uniform activation of p53 at a moderate level is well tolerated in the embryos. In contrast, mild activation of p53 in individual cells leads to a growth disadvantage and their out-competition when they are present together with nonactivated cells. These results suggest that p53 may coordinate at a multicellular level for optimal stress response and fitness of the organism.

  • The chronic elimination of pu.1-deficient microglia in zebrafish is mediated by Tp53-dependent cell competition.

    “we further showed that the chronic elimination of pu.1 -deficent microglia in zebrafish is mediated by Tp53-dependent cell competition”

    From Pu.1/Spi1 dosage controls the turnover and maintenance of microglia in zebrafish and mammals (2023) · cites this paper as Zhang et al., 2017

    The Results report p53-dependent out-competition of Mdm2+/−Mdm4+/− cells in mosaic mouse embryos. The paper does not study pu.1-deficient microglia, zebrafish, or their chronic elimination, so it supports the general mechanism but not the specific claim. (LLM, conf=0.88)

    “Tp53 is also involved in cell competition regulation in both hematopoietic and non-hemopoietic tissues (Bondar & Medzhitov, 2010, Zhang, Xie et al., 2017).”
  • Tp53-dependent cell competition depends on the relative level of Tp53 in competing cells.

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.
