Meanwhile, co-expression of PKCδ and NDRG1 downregulated the mesenchymal marker N-cadherin, Vimentin, and Snail expression and upregulated the epithelial marker E-cadherin (Figures 7A, B), indicating that PKCδ may enhance the invasion and migration ability of CRC cells by inhibiting NDRG1 to promote EMT. Here, CDH1 is linked to colorectal carcinoma.
