E-cadherin expression was decreased and the expression of N-cadherin and vimentin was up-regulated at the mRNA level, whereas Snail and vimentin was also up-regulated at the protein level, supporting that the knockdown of tRF-24-V29K9UV3IU promoted the epithelial–mesenchymal transition of tumor cells (Figures 2(i)–2(k)). This evidence concerns the gene CDH1 and neoplasm.
