Through the KEGG pathway enrichment analysis of intersection genes, 20 representative signaling pathways with p < 0.05 were identified (Figure 5), including JAK-STAT signaling pathway, EGFR tyrosine kinase inhibitor resistance, PI3K-Akt signaling pathway, MAPK signaling pathway, ErbB signaling pathway, Focal adhesion, Rap1 signaling pathway, Prolactin signaling pathway, Influenza A, Type II diabetes mellitus, cGMP-PKG signaling pathway, NOD-like receptor signaling pathway and Aldosterone synthesis and secretion. This evidence concerns the gene PRL and type 2 diabetes mellitus.
