Abstract

Few proteins are more studied than the p53 tumour suppressor, but what have we learned from these studies and what do we really know about p53 that can benefit clinical practice? The DNA sequence encoding p53 is frequently mutated in cancers but the functional outcomes of single mutations, in respect to loss or gain of different activities, especially in relation to immune evasion, are not clear. This illustrates p53's complexity which even after 40 years keeps providing surprises, but also explains why it has not yet lived up to its potential to benefit cancer treatment. We have reassessed a few key experiments that shaped the p53 field and we take a closer look at the interpretations of these experiments: what they have taught us, the resulting dogmas, and their potential clinical importance. One outcome is a more dynamic view of p53 in terms of its activity, its regulation, and downstream effectors, which will benefit the clinical application of p53 for diagnosis, prognosis, and therapy. Mutations and regulatory factors can have different effects on p53 activity depending on context, important but neglected aspects when interpreting p53 and its pathways in cancers. Even though p53 is undoubtedly unique as a multifunctional hub in different cellular pathways, the concept of a factor taking up different functions within a regulatory pathway during different conditions is not. In this sense, p53 continues to lead the way for a better understanding of the cellular and molecular mechanisms underlying cancer development in vivo. © 2021 The Pathological Society of Great Britain and Ireland.

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.
