TOX3 and hepatocellular carcinoma: The depletion of the tripartite motif containing 56 in hepatocellular carcinoma (HCC) may potentiate the accumulation of TOX high mobility group box family member 3 (TOX3), and further regulate the classical signaling pathways of MAPK and EMT by increasing the expression level of insulin‐like growth factor binding protein 3, eventually promoting the growth and metastasis of HCCs.
