摘      要：As for many other tumors,development of hepatocellular carcinoma(HCC)must be understood as a multistep process with accumulation of genetic and epigenetic alterations in regulatory genes,leading to activation of oncogenes and inactivation or loss of tumor suppressor genes(TSG).In the last decades,in addition to genetic alterations,epigenetic inactivation of(tumor suppressor) genes by promoter hypermet hylation has been recognized as an important and alternative mechanism in *** HCC,aberrant methylation of promoter sequences occurs not only in advanced tumors, it has been also observed in premalignant conditions just as chronic viral hepatitis B or C and cirrhotic liver. This review discusses the epigenetic alterations in hepatocellular carcinoma focusing DNA methylation.
