Abstract

p53—still hazy after all these years?: The gene encoding the p53 tumor suppressor protein is the most frequently mutated gene in human cancer. Yet decades after the gene's discovery, the biology of cancer-associated missense mutations in p53 is still being debated. Previous studies have suggested that missense mutations confer tumor-promoting functions to p53. Boettcher et al. conducted a detailed analysis of p53 missense mutations in human leukemia, drawing on methodologies including genome editing, a p53 saturation mutagenesis screen, mouse models, and clinical data (see the Perspective by Lane). They found no evidence that p53 missense mutations confer an oncogenic gain of function. Rather, the mutations exerted a dominant-negative effect that reduced the tumor suppressor activity of wild-type p53. Science , this issue p. 599 ; see also p. 539

  • Loss of the TP53-WT allele confers an additional fitness advantage to TP53-sAML LSCs.

    “Despite the known dominant negative and/or gain of function effect of certain TP53 mutations28,42, loss of the TP53-WT allele, a genetic event associated with a particularly dismal prognosis2, confers an additional fitness advantage to TP53-sAML LSCs.”

    From Single-cell multi-omics identifies chronic inflammation as a driver of TP53-mutant leukemic evolution (2023) · cites this paper as [28]

    In the passage discussing mouse hematopoietic stem and progenitor cells (section labeled Abstract; page unavailable), cells with a TP53 missense mutation and no wild-type allele outcompeted cells retaining a wild-type allele after DNA damage. That supports an additional fitness advantage in that experimental setting, but the paper does not establish it for TP53-sAML leukemia stem cells. In the citing sentence, the citation is attached to the earlier statement about mutation effects, not directly to the LSC conclusion. (LLM, conf=0.88)

  • Similar findings were observed in TP53 knock-out or mutant isogenic MOLM13 cell lines.

    “Similar findings were observed in TP53 knock-out or mutant isogenic MOLM13 cell lines (Extended Data Fig. 5m)28.”
  • Loss of the Trp53-WT allele confers an additional fitness advantage to Trp53-mutant HSPC following DNA damage.

    “loss of the Trp53-WT allele confers an additional fitness advantage to Trp53-mutant HSPC following DNA damage as previously described28”

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.
