For example, knockdown of lncRNA TUG1 can promote the expression of miR-384 to inhibit EMT and thus suppress the progression of nasopharyngeal carcinoma23; downregulation of lncRNA-ATB can repress EMT of breast cancer cells by increasing the expression of miR-141-3p.24 E-cadherin and vimentin are reported as EMT markers.25 In this study, we demonstrated that SNHG6 could increase the invasiveness of PA cells by inducing EMT. This evidence concerns the gene TUG1 and breast cancer.
