Deficiency of DJ-1 Ameliorates Liver Fibrosis through Inhibition of Hepatic ROS Production and Inflammation.

ABSTRACT: Liver fibrosis is a global health problem and previous studies have demonstrated that reactive oxygen species (ROS) play important roles in fibrogenesis. Parkinson disease (autosomal recessive, early onset) 7 (Park7) also called DJ-1 has an essential role in modulating cellular ROS levels. DJ-1 therefore may play functions in liver fibrogenesis and modulation of DJ-1 may be a promising therapeutic approach. Here, wild-type (WT) and DJ-1 knockout (DJ-1 KO) mice were administrated with carbon tetrachloride (CCl4) to induce liver fibrosis or acute liver injury. Results showed that DJ-1 depletion significantly blunted liver fibrosis, accompanied by marked reductions in liver injury and ROS production. In the acute CCl4 model, deficiency of DJ-1 showed hepatic protective functions as evi
