KEGG pathway enrichment analysis showed that EMT-related DEPs were mainly enriched in human papillomavirus infection, PI3K/Akt signaling pathway, hepatitis C infection, human T−cell leukemia virus 1 infection, chemical carcinogenesis−reactive oxygen species, microRNAs in cancer, and insulin signaling pathway (Figure 3D). This evidence concerns the gene AKT1 and hepatitis C virus infection.
