Pathway enrichment analysis of hub genes indicated that apoptosis, cell cycle, and epithelial–mesenchymal transition (EMT) pathway were activated, and hormone androgen receptor (AR), hormone estrogen receptor (ER), RAS/mitogen-activated protein kinase (RAS/MAPK), and receptor tyrosine kinase (RTK) were inhibited in HCC (Figure 10). The gene discussed is NTRK1; the disease is hepatocellular carcinoma.
