AKT1 and hepatocellular carcinoma: In this study, sorafenib‐resistant HCC cells generated from sorafenib‐sensitive human HCC cells were shown to overproduce hepatocyte growth factor (HGF) and overexpress c‐Met kinase and its phosphorylated form, leading to the activation of Akt and ERK (extracellular signaling‐regulated kinase) pathways.
