We examine genome-wide DNA methylation profiles in 66 pairs of HCC tumor and adjacent non-tumor tissues. After Bonferroni adjustment, a total of 130,512 CpG sites significantly differed in methylation level in tumor compared to non-tumor tissues, with 28,017 CpG sites hypermethylated and 102,495 hypomethylated in tumor tissues. Most (60.1%) significantly hypermethylated CpG sites are located in CpG islands. These results demonstrate the significance of aberrant DNA methylation in HCC tumorigenes...
