Abstract

Dynamic Responses: Expression of the tumor suppressor p53 is activated in response to cell stress. The dynamics of p53 activation can vary, depending on the stressor, resulting in either pulsatile or constant p53 levels; however, the functional consequence of these different dynamics is unclear. Purvis et al. (p. 1440 ) developed a method to control p53 dynamics in human cells. Pulsing p53 selectively activated genes involved in cell cycle arrest and DNA repair, allowing recovery from DNA damage. In contrast, sustained p53 promoted induction of terminal genes leading to cellular senescence. Thus, protein dynamics can affect cell fate decisions.

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.
