PRMT5 promotes epithelial-mesenchymal transition via EGFR-β-catenin axis in pancreatic cancer cells.

ABSTRACT: Protein arginine methyltransferase 5 (PRMT5) has been implicated in the development and progression of human cancers. However, few studies reveal its role in epithelial-mesenchymal transition (EMT) of pancreatic cancer cells. In this study, we find that PRMT5 is up-regulated in pancreatic cancer, and promotes proliferation, migration and invasion in pancreatic cancer cells, and promotes tumorigenesis. 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. More importantly, we find that PRMT5 knockdown decreases the phosphorylation
