title: The phosphatase PP2A links glutamine to the tumor suppressor p53.
abstract: In this issue of Molecular Cell, Reid et al. (2013) show that glutamine withdrawal causes PP2A-mediated activation of p53 through its regulator EDD, linking levels of a critical metabolite to an important regulator of cell survival and proliferation.
