Figure 2. Enrichment and protein-protein interaction analysis of differentially expressed IRGs. (A) GO analysis of the immune-related genes. (B) Circular plot of the top seven most significant KEGG pathways. (C) Network plot of enriched terms: colored by cluster ID, where terms with a similarity > 0.3 are connected by edges. (D) Protein-protein interaction network and MCODE components identified in the gene lists.
