Among the identified highly enriched functional groups, three detected terms were also associated with antiviral response, including “viral process”, “response to virus” and “hepatitis C and hepatocellular carcinoma”, which contained DEGs involved in the regulation of innate antiviral immunity (IFIT1, IFIT2, IFIT3, IFI16, ISG15, ISG20, LCN2, LGALS8, etc.). This evidence concerns the gene LCN2 and hepatocellular carcinoma.
