Prognostic Liver Signature for NAFLD (PLS-NAFLD) profiles of cell-based PLS system treated with free fatty acids (FFA) and IDO1 inhibitor, epacadostat.


ABSTRACT: Non-alcoholic fatty liver disease (NAFLD), alongside the global obesity epidemic, is rapidly emerging as a dominant liver disease etiology that leads to progressive liver fibrosis, its terminal stage, cirrhosis, and hepatocellular carcinoma (HCC). We identified and validated a 133-gene signature (Prognostic Liver Signature for NAFLD [PLS-NAFLD]) to predict long-term HCC risk in patients with NAFLD. By analyzing PLS-NAFLD, IDO1 was identified as a potenial chemopreventive target for HCC from NAFLD. To test this hypothesis, we utilized our clinical-prognostic-signature-inducible cell culture model. We first confirmed that free fatty acid treatment (800 μM oleic acid and 400 μM palmitic acid) can induce PLS-NAFLD, then IDO1 inhibitor, epacadostat, can reverse the high-risk pattern in a dose-dependent manner.
