KEGG enrichment analysis showed that apoptosis, hepatitis B, IL17 signaling pathway, TNF signaling pathway, NOD-like receptor signaling pathway, nonalcoholic fatty liver disease, metabolic pathways, the toll-like receptor signaling pathway, bile secretion, and necroptosis were the top 10 signaling pathways (Figure 5(b)). The gene discussed is IL17A; the disease is hepatitis B virus infection.
