Fig. 1From: Four-gene signature predicting overall survival and immune infiltration in hepatocellular carcinoma by bioinformatics analysis with RT‒qPCR validationIdentification of differentially expressed genes (DEGs) in GEO datasets. (A) volcano plots from GSE45436, (B) volcano plots from GSE101685, (C) volcano plots from GSE112790, (D) volcano plots from GSE121248, (E) venn plots from upregulated DEGs from four included GEO datasets, (F) venn plots from downregulated DEGs from four included GEO datasets, and (G) heatmap of the top 20 downregulated and upregulated DEGs. Green and red colors represent the down- and upregulated |FC| values, respectively. Values of P < 0.05 and lg|FC|≥ 2 were considered significantBack to article page
