Research Abstract

Hepatitis C virus (HCV) infection induces interferon (IFN). IFN induces antiviral molecules that suppress HCV replication. Although IFN stimulated genes, PKR, MxA, and OAS suppressed HCV replication, only MxA was essential in IFN treatment. In addition, chronic hepatitis C (CHC) patients having OAS polymorphism with weaker anti-HCV activity were easier to develop cirrhosis. There are individual differences for development of hepatocellular carcinoma (HCC) in patients with CHC. Genome wide association study (GWAS) identified HCC susceptible single nucleotide polymorphism (SNP) in MICA gene.
