WebMay 16, 2011 · It was suggested that the cell fate between survival and death may be determined by counting the number of p53 pulses. The strength of DNA damage is repeatedly evaluated; the cell survives after transient p53 pulses, or apoptosis is induced by sustained p53 pulses. WebFeb 18, 2024 · Cell-autonomous changes in p53 expression govern the duration and outcome of cell-cycle arrest at the G2 checkpoint for DNA damage. Here, we report that mitogen-activated protein kinase (MAPK) signaling integrates extracellular cues with p53 dynamics to determine cell fate at the G2 checkpoint.
