Genome Stability Requires p53

Open access
Eischen, Christine M.·2016·Cold Spring Harbor Perspectives in Medicine

Abstract

It is now clear that functional p53 is critical to protect the genome from alterations that lead to tumorigenesis. However, with the myriad of cellular stresses and pathways linked to p53 activation, much remains unknown about how p53 maintains genome stability and the proteins involved. The current understanding of the multiple ways p53 contributes to genome stability and how two of its negative regulators, Mdm2 and Mdmx, induce genome instability will be described.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Loss of TP53 and RB1 likely occurs early in osteosarcoma transformation, with TP53 inactivation required to propagate abnormal genomes, followed by rapid accumulation of driver lesions such as MYC amplification, PTEN loss and deletion of ATRX.

    “Using these genomic aberrations to infer the evolution of the tumours, loss of TP53 and RB1 likely occurs early in the transformation process (with TP53 inactivation required to propagate abnormal genomes 39,40,41 ), followed by rapid accumulation of driver lesions such as MYC amplification, PTEN loss 42 and deletion of ATRX”

  • The most likely order of events for osteosarcoma evolution is loss of TP53 and RB1 as early events, with TP53 loss likely initiating genomic instability, followed by whole-genome doubling, gain of 8q (CMYC) and loss of 10q (PTEN).

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.
