KEGG pathway analysis identified several key signaling pathways associated with HCC, including the PI3K-AKT signaling pathway, p53 signaling pathway, apoptosis pathway, mTOR signaling pathway, metabolic pathways, MAPK signaling pathway, FOXO signaling pathway, cell cycle, and AMPK signaling pathway. The gene discussed is AKT1; the disease is hepatocellular carcinoma.
