Figure 2. Identification of prognostic MMPs-related DEGs in hepatocellular carcinoma. (A) Prognostic MMPs-related DEGs are identified from MMPs-related genes through univariate Cox regression analysis. (B) GO enrichment analysis of prognostic MMPs-related DEGs, including biological processes (BP), molecular functions (MF), and cellular components (CC). (C) KEGG enrichment analysis of prognostic MMPs-related DEGs. (D) HCC patients were divided into two clusters according to the consensus clustering matrix (k = 2).
