Identification of differentially expressed DCGs in TCGA-LUAD and normal samples. A Differential expression volcano plot based on DCGs (red: P < 0.05 and |logFC|> = 1, blue: only P < 0.05). B The heatmap of 24 differentially expressed DCGs in LUAD and normal samples (blue: low expression level, orange: high expression level, **P < 0.01, ***P < 0.001). C Protein–protein interaction (PPI) network of 22 DCGs. D The hub genes calculated by the PPI network
