TWIST1 and hepatocellular carcinoma: Interestingly, SNAI1 established by several groups including us to take part in EMT induction by GLI1 was found not to be up-regulated by Cav-1 in vitro in this investigation, whereas Twist, another well-known EMT inducer of HCC, was found up-regulated by Cav-1, which points out that GLI1 could induce HCC cell EMT through both the GLI1-SNAI1 axis and the GLI1-Cav1-Twist cascade.
