PPI network and the key gene analysis. (a) Volcano plot of the ARGs. (b) Heatmap of the 53 differentially expressed ARGs. (c) PPI network of the differentially expressed genes. (d) MCODE analysis of the differentially expressed genes. (e, f) Expression heat map of the four key genes in the high- and low-risk groups. K-M survival curves for the high- and low-risk groups stratified by the four key genes: (g) TGFβ2; (h) SERPING1; (i) SERPINE1; (j) TIMP1. PPI: protein-protein interaction.
