RESUMO
Liver fibrosis is a compensatory response in the process of tissue repair after chronic liver injury, and it is also a necessary pathological process in the progression of a variety of chronic liver diseases. In the pathological state, the imbalance between hepatic oxidative system and antioxidant system can lead to the excessive production or insufficient clearance of reactive oxygen species (ROS)/reactive nitrogen species (RNS), which may induce the injury of hepatocytes, expand inflammatory response, and promote the development and progression of liver fibrosis. As a master regulator of oxidative stress and inflammatory response, NF-κB plays a key role in the process of liver fibrosis. Therefore, the cascade interaction between ROS/RNS and the NF-κB signaling pathway plays a guiding role in further clarifying the pathogenesis of liver fibrosis and exploring effective prevention and treatment strategies. This article reviews and discusses the interaction between ROS/RNS and the NF-κB signaling pathway and its important role in the progression of liver fibrosis, so as to provide strategies and references for targeted therapy for liver fibrosis.
