Interestingly, in CRC as well as in HCC, the rescue expression of KCNQ1 in cell lines that do not express this channel, restores the expression of epithelial markers such as E-cadherin, lowers the expression of mesenchymal markers such as N-cadherin and restores the ability of cell to form spheroids in 3D culture. Here, KCNQ1 is linked to colorectal carcinoma.
