According to the pathway enrichment analysis, 104 pathways, including pathways in cancer, human cytomegalovirus infection, PI3K-Akt signaling pathway, Kaposi sarcoma-associated herpesvirus infection, lipid and atherosclerosis, hepatitis C, Epstein–Barr virus infection, cell cycle, measles, cellular senescence, chemokine signaling pathway, and human T-cell leukemia virus 1 infection, were affected by key targets (p < 0.05) (Figures 6A, B). The gene discussed is AKT1; the disease is hepatitis C virus infection.
