Abstract

In response to cellular stress signals, the tumour suppressor p53 accumulates and triggers a host of antineoplastic responses. For instance, DNA damage activates two main p53-dependent responses: cell cycle arrest and attendant DNA repair or apoptosis (cell death). It is broadly accepted that, in response to DNA damage, the function of p53 as a sequence-specific transcription factor is crucial for tumour suppression. The molecular determinants, however, that favour the initiation of either a p53-dependent cell cycle arrest (life) or apoptotic (death) transcriptional programme remain elusive. Gaining a clear understanding of the mechanisms controlling cell fate determination by p53 could lead to the identification of molecular targets for therapy, which could selectively sensitize cancer cells to apoptosis. This review summarizes the literature addressing this important question in the field. Special emphasis is given to the role of the p53 response element, post-translational modifications and protein-protein interactions on cell fate decisions made by p53 in response to DNA damage.

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.
