Abstract :
Sirtuin deacetylases are linked to longevity, aging, and stress responses. In this issue of Cancer Cell, Kim et al. show that SIRT3 functions as a tumor suppressor by enhancing the expression of mitochondrial MnSOD. Loss of SIRT3 leads to increased mitochondrial ROS, which then enhances cellular transformation and tumor growth.
