TNF and hepatocellular carcinoma: KEGG enrichment analysis showed that the key targets were mainly MAPK signaling pathway, IL-17 signaling pathway, calcium signaling pathway, protein digestion and absorption signaling pathway, Wnt signaling pathway, cytokine receptor interaction signaling pathway, TNF signaling pathway, p53 signaling pathway, hepatocellular carcinoma signaling pathway, HIF-1 signaling pathway and other information pathways.
