Silencing PRMT5 induces epithelial marker E‐cadherin expression and down‐regulates expression of mesenchymal markers including Vimentin, collagen I and β‐catenin in PaTu8988 and SW1990 cells, whereas ectopic PRMT5 re‐expression partially reverses these changes, indicating that PRMT5 promotes EMT in pancreatic cancer. This evidence concerns the gene CDH1 and familial pancreatic carcinoma.
