Comparison of differentially expressed genes and deregulated pathways in the GE1 and GE2 hepatocellular carcinoma (HCC) subgroups. a The two gene lists resulting from the pair-wise t tests—10 GE1-HCC versus 17 NT and 13 GE2-HCC versus 17 NT—were compared via Venn Diagram analysis. b Pathway enrichment analysis was performed using the same two gene lists, and the Kyoto Encyclopedia of Genes and Genomes (KEGG) was used to identify pathways with the significant enrichment in the deregulated genes (Fisher’s P value ≤ 0.05) in GE1 and GE2 HCC subgroups
