Finally, four significant KEGG enrichment pathways were identified (P < 0.05, Table 1): beta-Alanine metabolism (SMOX, HIBCH), Pathways in cancer (GLI2, AR, TXNRD3, TRAF3, FGF16), Non-homologous end-joining (MRE11), Epstein-Barr virus infection (TRAF3, PSMD13, SIN3A). The gene discussed is SMOX; the disease is Epstein-Barr virus infection.
