Hepatocyte phosphatase DUSP22 mitigates NASH-HCC progression by targeting FAK

Mechanisms underlying the pathogenesis of nonalcoholic steatohepatitis are unclear. Here, the authors show that ROS-mediated DUSP22 degradation participates in the progression of fatty liver, contributing to the development of NASH and associated HCC via regulating FAK and its downstream ERK1/2 and NF-κB signaling cascade.
