GJB1 and hepatocellular carcinoma: Using similar techniques, a potential effect of Snail expression was shown in EMT-associated invasion in HCC cells, while the expression of phosphorylated β-catenin (Y654), the presence of which marks transcriptional activity and nuclear translocation of β-catenin [93], was negatively correlated with Cx32 expression, accompanied with a consistent change in Wnt1 expression.
