The overrepresented pathways (Figure 3B) are the prolactin pathway, cell surface receptor protein tyrosine kinase signaling pathway, EGF EGFR signaling, MAPK1 (ERK2) activation, VEGFA, VEGFR2 signaling, positive regulation of leukocyte proliferation, and EBV infection (Supplementary Material 3). Here, MAPK1 is linked to Epstein-Barr virus infection.
