Identification of differentially expressed genes and their participating biological roles. (A) The differentially expressed genes in TCGA, GSE25097, GSE36376, and GSE76427 datasets. Red is upregulated expression and green is downregulated expression in HCC. Genes with the largest fold change are labeled. FC, fold change. (B) The intersection of upregulated (left) or downregulated (right) expressed DEGs in four datasets. (C) GO enrichment results of common DEGs. MF molecular functions, CC cellular composition, BP biological processes. (D) KEGG pathways of common DEGs involved in.
