Western blot assay revealed that LINC01939 overexpression led to increase the expression of the epithelial markers E-cadherin and α-catenin and decrease the expression of the mesenchymal markers vimentin and N-cadherin (Fig. 5c), indicating that LINC01939 may inhibit GC migration and invasion via regulating EMT pathway. This evidence concerns the gene CDH2 and gastric cancer.
