Identification of HCC clusters based on DEGs. (A) The GO pathway annotation and (B) the KEGG annotation in DEGs. (C) three DRG clusters were identified based on the optimal K value(K = 3). (D) PCA analysis of three DRG clusters. (E) Survival curves for three DRG clusters. (F) The heatmap containing clinical information, different HCC subtypes, and gene expression levels. (G) Box plot of differences in expression levels of 24 DRGs in three DRG clusters
