Tumor suppression by p53: is apoptosis important or not?
Abstract
The mechanisms by which p53 suppresses tumor growth remain ill defined. In this issue of Cell Reports, Timofeev et al. (2013) and Valente et al. (2013) reveal context-dependent contributions of p53-dependent apoptosis to its tumor-suppressive function.
