ABSTRACT: Introduction
Primary sclerosing cholangitis (PSC) is a chronic liver disease of unknown cause contributing to cirrhosis and cancer but has no cure. PSC is characterized by inflammation within ductal fibrosis, progressive bile duct narrowing and loss, with damage to cholangiocytes (epithelial cells affecting bile production) and liver repair. ET-1, produced by cholangiocytes, contributes to fibrosis, vasoconstriction, and inflammation via ETA receptors. In patients, ET-1 and ETA gene expression are elevated and ETA antagonists reduce disease progression in PSC animal models. Ongoing clinical trials of portal hypertension in liver disease are testing the efficacy of a new treatment strategy combining ETA-selective antagonist zibotentan with
