Figure 7. Protein-protein interaction network and functional enrichment analysis of spliceosome-related genes. (A) The protein-protein interaction network between 25 spliceosome-related genes. (B–E) The 25 spliceosome-related genes were mainly enriched in the biological process (B), cellular component (C), molecular function (D), and KEGG pathway (E). (F, G) GSEA identified the signaling pathways in which genes expressed in the high-risk (F) and low-risk score patients (G) enriched.
