Mechanism Description miRNA-221-3p desensitizes pancreatic cancer cells to 5-fluorouracil by targeting RB1. miR221-3p down-regulated RB1 expression by directly binding to its 3'-UTR and therefore caused increased several aspects of pancreatic cancer pathogenesis, including proliferation, migration, invasion, and epithelial-mesenchymal transition (EMT).
