Figure 5. Protein-protein interaction (PPI) network analyses of PDEPs were performed, and the four most significant modules were identified by the molecular complex detection (MCODE) algorithm. (A) Enrichment of domains in differentially expressed proteins. (B) Enrichment of KEGG pathways in differentially expressed proteins. (C) Interaction network of differentially expressed proteins. (D–H) The five most significant MCODE modules.
