Congrats to Steve on his Hepatology paper!

Read all about Steve’s REX1 story in the upcoming issue of Hepatology. In brief, the work describes a critical repressive function of REX1 in maintenance of HCC cells by regulating MKK6 binding and p38 MAPK signaling. REX1 deficiency induced enhancement of p38 MAPK signaling, leading to F-actin reorganization and activation of NRF2-mediated oxidative stress response, which collectively contributed to enhanced stemness and metastatic capabilites of HCC cells.
