MiR-374b-5p inhibits KDM5B-induced epithelial-mesenchymal transition in pancreatic cancer.

ABSTRACT: Micro(mi)RNAs play a critical regulatory role in the progression and metastasis of pancreatic cancer (PC). In this study, we aimed to reveal the mechanisms of miR-374b-5p in regulating epithelial-mesenchymal transition (EMT) in PC. Gene Expression Omnibus datasets (GSE24279 and GSE71533) and the pancreatic ductal adenocarcinoma (PDAC) cohort of The Cancer Genome Atlas were employed to screen for potential prognostic miRNAs. The expression of miR-374b-5p was measured by quantitative real-time polymerase chain reaction (qRT-PCR) in 78 paired PDAC tissue samples. The biological effects of miR-374b-5p were investigated using in vitro and in vivo assays. Luciferase reporter assays and immunohistochemical tests were conducted to verify the interaction between miR-374b-5p and its pr
