Requirement for p53 and p21 to Sustain G 2 Arrest After DNA Damage

Abstract

After DNA damage, many cells appear to enter a sustained arrest in the G 2 phase of the cell cycle. It is shown here that this arrest could be sustained only when p53 was present in the cell and capable of transcriptionally activating the cyclin-dependent kinase inhibitor p21. After disruption of either the p53 or the p21 gene, γ radiated cells progressed into mitosis and exhibited a G 2 DNA content only because of a failure of cytokinesis. Thus, p53 and p21 appear to be essential for maintaining the G 2 checkpoint in human cells.

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

  • p21 is required for p53-mediated G2/M cell cycle arrest.

    “p21 is required for p53-mediated G1/S146, 147, 148 and also for G2/M cell cycle arrest.149”

    From Census and evaluation of p53 target genes (2017) · cites this paper as [149]

  • In HCT-116 cells, p21 knockout after transient G2 arrest leads to aberrant mitoses, polyploidy, or cell death.

    “Indeed, after transiently arresting in G2, HCT-116 cells in which p21 was knocked out eventually underwent aberrant mitoses, leading to polyploidy or cell death.53,55”

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.
