(A) Mean β value densities of the tumor(T)/normal(N) samples included in two public HCC datasets (TCGA-LIHC, GSE54503). (B) Smoothed density curves of the genomic index distributions and p-values (two-tailed t-test) for all pairwise comparisons between TCGA-LIHC/GSE54503 datasets and epimarkers (epiHCC1, epiHCC2). (C) Differential β value density of the TCGA-LIHC/GSE54503 datasets and epimarkers (epiHCC1, epiHCC2). (D) Mean genomic index of aberrantly methylated sites |Δβ| ≥ 0.3) in driver genes that have been detected by at least two to five computational methods. (E). Mean genomic index of all TCGA-LIHC and GSE54503 differentially methylated sites compared with the genomic index of COSMIC Tier-1 (T1) cancer gene census. (F). Semantic similarity plot correlating highly-ranked sites of the TCGA-LIHC and GSE54503 datasets, according to MeinteR, with the COSMIC T1, Tier 2 (T2) Gene Census, KEGG HCC pathway, Driver-5 genes and epigenetic markers (epiHCC1, epiHCC2).
