Figure 2From: DNA hypermethylation of zygote arrest 1 (ZAR1) in hepatitis C virus positive related hepatocellular carcinoma Average methylation level of each CpG site in Zar1 in HCC and nontumorous liver tissues. Open bars indicate nontumorous tissues, and filled bars indicate HCC tissues. All CpG sites showed a significantly higher methylation level in HCC than in nontumorous tissues (p < 0.05). Data are shown as mean ± SD.Back to article page
