Next, by KEGG pathway enrichment analysis, we found that the 6 core target genes were mainly enriched in the EGFR tyrosine kinase inhibitor (EGFR-TKI) resistance, Kaposi sarcoma-associated herpesvirus (KSHV) infection, and human cytomegalovirus (HCMV) infection pathways. The gene discussed is EGFR; the disease is cytomegalovirus infection.
