Using pvalueCutoff = 0.05 and qvalueCutoff = 0.05 as the criteria, we screened the pathway analysis of the top 10 of p-value, which was predominantly enriched in mitogen activated protein kinase (MAPK) signaling pathway, miRNA in cancer, human cytomegalovirus infection, Hepatitis B, Kaposi Sarcoma-associated herpesvirus infection, cellular senescence, breast cancer, Yersinia infection, neurotrophin signaling pathway, and EGFR tyrosine kinase inhibitor resistance (Figure 4). The gene discussed is BDNF; the disease is breast carcinoma.
