FOXM1 and liver cancer: In this study, we found Nrf2 was transcriptionally activated by FoxM1, and Prx I was activated by the H-rasG12V/pERK/FoxM1/Nrf2 pathway and suppressed ROS-induced hepatic cancer-cell death along with formation of a positive feedback loop with Ras/ERK/FoxM1/Nrf2 to promote hepatic tumorigenesis.
