Abstract |
The exact mechanisms of metastasis for pancreatic cancer remain to be uncovered. This study aimed to elucidate the potential functional mechanism of miR-135b-5p in migration, invasion and epithelial-to-mesenchymal transition (EMT) of pancreatic cancer cells. By real-time PCR and analysis of GEO database, we determined the up-regulated expression of miR-135b-5p in pancreatic cancer tissues and cell lines. Clinically, highly expressed miR-135b-5p was closely related to advanced TNM stage, more lymph node metastasis, more distant metastasis and worse overall survival (OS) and disease-free survival (DFS). Functionally, Transwell assays indicated that miR-135b-5p was a promoter for migration and invasion of pancreatic cancer cells. Additionally, immunohistochemistry staining and Western blot showed that highly expressed miR-135b-5p accelerated EMT process of pancreatic cancer cells. Furthermore, a series of experiments and rescue experiments revealed that Nuclear Receptor Subfamily 3 Group C Member 2 (NR3C2) was the target of miR-135b-5p in pancreatic cancer cells, mediating the promotion effects of miR-135b-5p on the tumor cells migration, invasion and EMT. In conclusion, miR-135b-5p, maybe a novel therapeutic target for pancreatic cancer, promoted migration, invasion and EMT of pancreatic cancer cells by targeting NR3C2.
