Supplementary Figure 1. Pie graph showing the distribution of the most abundant miRNAs (top 20) in HCC tumor and non-tumor tissues. Of these, 16 abundant miRNAs were found in both tumor and non-tumor tissues. The top 5 abundant miRNAs account for more than 58% of all detectable miRNAs. MiR-122, the most abundant miRNA previously reported in liver tissue is the 7th most common in both tumor and non-tumor tissues
