MAPK14 and Epstein-Barr virus infection: Besides, pathway enrichment analysis was also conducted for the genes involved in the TF-DEG regulatory network, the enriched pathways included TNF signaling pathway (p = 4.89E-07, which involved CEBPB and MAPK14), Epstein-Barr virus infection (p = 2.09E-04), and osteoclast differentiation (p = 5.64E-04) (Table 5).
