Identification of immune cell-related prognostic genes characterized by a distinct microenvironment in hepatocellular carcinoma

Figure 2 Identification of immune cell-related genes by array screening. A: Heatmap of the identified immune cell-related genes (ICRGs) between the tumor group and the normal group. Blue: Low expression level; red: High expression level; B: Protein-protein interaction network of the genes (cutoff = 0.9); C: Univariate Cox regression analysis of ICRGs.
