Differentially expressed genes analyses. (A) The differentially expressed genes of HCC patients’ in TCGA database; (B) The differentially expressed genes of HCC patients’ in the GSE60502 dataset; (C) Venn diagram showing the 27 shared genes of TCGA database and the GSE60502 dataset. DEGs, differentially-expressed genes; TCGA_diff, DEGs in TCGA database; TCGA_brown, brown module in TCGA database; GEO_diff, DEGs in GSE60502 dataset; GEO_blue, blue module in GSE60502 dataset. DEGs, differentially-expressed genes; HCC, hepatocellular carcinoma; TCGA, The Cancer Genome Atlas.
