MAGI1 and hepatocellular carcinoma: To investigate the role of MAGI1 in HCC, we used MAGI1 shRNA to silence the expression of MAGI1 in the HuH-7 cell line (Supplementary Figure 1C), and MAGI1 overexpression vectors were used to increase the expression of MAGI1 in the HB611 cell line (Supplementary Figure 1D).
