Classification of HCC subtypes and exploration of biological functions. A Unsupervised consensus clustering analysis. B The PCA plots showed the cluster could clearly distinguish HCC patients into two groups based on their expression profiles. C The Kaplan–Meier curve between the two clusters. D The Venn diagram was utilized to display DEGs between cluster A and cluster B. E GO pathway enrichment of differentially expressed genes between cluster A and cluster B. F KEGG pathway enrichment of differentially expressed genes between cluster A and cluster B.*P < 0.05; **P < 0.01
