p53 as an Effector or Inhibitor of Therapy Response

Cold Spring Harb Perspect Med. 2015 Dec 4;6(1):a026260. doi: 10.1101/cshperspect.a026260.

Abstract

Although integrity of the p53 signaling pathway in a given tumor was expected to be a critical determinant of response to therapies, most clinical studies failed to link p53 status and treatment outcome. Here, we present two opposite situations: one in which p53 is an essential effector of cure by targeted leukemia therapies and another one in advanced breast cancers in which p53 inactivation is required for the clinical efficacy of dose-dense chemotherapy. If p53 promotes or blocks therapy response, therapies must be tailored on its status in individual tumors.
