Emricasan, a pan-caspase inhibitor, improves survival and portal hypertension in a murine model of common bile-duct ligation.

ABSTRACT: Development of portal hypertension (PHT) is a central prognostic factor in patients with cirrhosis. Circulating microparticles (MPs) are released by hepatocytes in a caspase-dependent manner, are increased in circulation of patients with cirrhosis, and contribute to PHT via induction of impaired vasoconstrictor responses. Here, we tested the hypothesis that emricasan, a pan-caspase inhibitor, ameliorates PHT and reduction in release of MPs. We used a short-term and long-term protocol following common bile-duct ligation (BDL) in C57BL/6 mice (10 and 20 days, respectively). Mice were treated daily via intraperitoneal injection with 10 mg/kg/day of emricasan or placebo. Circulating MP levels were analyzed using flow cytometry and function via ex vivo angiogenesis assays. In contrast to BDL-pl
