NRF2: Translating the Redox Code.

Cancer requires mechanisms to mitigate reactive oxygen species (ROS) generated during rapid growth, such as induction of the antioxidant transcription factor, Nrf2. However, the targets of ROS-mediated cytotoxicity are unclear. Recent studies in pancreatic cancer show that redox control by Nrf2 prevents cysteine oxidation of the mRNA translational machinery, thereby supporting efficient protein synthesis.
