Real-time PCR showed that exogenous EBV-miR-BART6-3p mimics increased expression of the epithelial marker E-cadherin (CDH1) and decreased the mesenchymal marker N-cadherin (CDH2), and the transcription factor β-catenin and Snail (encoded by the SNAL1 gene) in EBV-negative tumor cell lines (5-8 F, HNE2 and AGS) at the mRNA level (Figure 6a). Here, CDH2 is linked to neoplasm.
