The role of microRNA-132 in human pancreatic ductal adenocarcinomas is still ambiguous. We explored the association between microRNA-132 and pancreatic ductal adenocarcinoma prognosis. The expression of microRNA-132 in 50 pancreatic ductal adenocarcinoma tissue samples and pancreatic ductal adenocarcinoma cell lines was examined, and the association between its expression and pancreatic ductal adenocarcinoma prognosis was assessed. Functional analysis and factors downstream of microRNA-132 were investigated. Kaplan-Meier survival curves showed that high expression of microRNA-132 was a significant prognostic factor for 1-year survival of patients with pancreatic ductal adenocarcinoma ( P = .028). Multivariate analysis for overall survival indicated that high expression of microRNA-132 was an independent prognostic factor for patients with pancreatic ductal adenocarcinoma ( P = .044). Low expression of microRNA-132 was associated with poor prognosis in pancreatic ductal adenocarcinoma. Ectopic expression of microRNA-132 significantly inhibited proliferation and promoted apoptosis of 2 pancreatic ductal adenocarcinoma cell lines. Bioinformatic analysis revealed that microRNA-132 may exert its effects on pancreatic ductal adenocarcinoma through downregulating mitogen-activated protein kinase 3 and nuclear transcription factor Y subunit α. The results of this study further our understanding of the relationship between microRNA-132 and pancreatic ductal adenocarcinoma by showing that microRNA-132 might inhibit the progression of pancreatic ductal adenocarcinoma by regulating mitogen-activated protein kinase and nuclear transcription factor Y subunit alpha.

Background. One of the microRNAs (miRNAs) known to be associated with cancer development is miR-607. The aim of this study is to investigate the clinical significance and diagnostic and prognostic value of miR-607 and to explore its potential role in pancreatic ductal adenocarcinoma (PDAC). Methods. The expression levels of miR-607 were assessed by quantitative real-time polymerase chain reaction (qRT-PCR). The correlation between miR-607 expression and clinical characteristics was analyzed by the Chi-square test. Overall survival (OS) and progression-free survival (PFS) were evaluated via the Kaplan–Meier method, and the association between miR-607 expression and OS was investigated by the Cox proportional hazard analysis. The diagnostic value was estimated via receiver operating characteristic (ROC) curve analysis. The effect of miR-607 overexpression on cell migration, invasion, and epithelial-mesenchymal transition (EMT) was determined by wound-healing, Transwell invasion, and Western blotting assays. Results. miR-607 levels were downregulated in PDAC tumor tissues compared with normal tissues. Also, low miR-607 levels were observed in serum samples from PDAC patients than that in healthy controls. The miR-607 level was found to be closely correlated with lymphatic metastasis and liver metastasis, perineural invasion, and OS and PFS, and the low miR-607 level was an independent prognostic factor for the poor OS of PDAC patients. Furthermore, the area under the curve (AUC) of serum miR-607 for discriminating PDAC patients was 0.785 with a sensitivity of 0.647 and a specificity of 0.772, which was better than those for CA19-9 (AUC: 0.702, sensitivity: 0.607, specificity: 0.736) and CEA (AUC: 0.648, sensitivity: 0.542, specificity: 0.670). The AUC (0.863), sensitivity (0.766), and specificity (0.831) of their combination in the diagnosis of PDAC were better than those for alone. Moreover, ectopic overexpression of miR-607 could inhibit cell migration and invasion of BxPc-3 and PANC-1 cells by decreasing EMT ability. Conclusions. Low serum miR-607 level may serve as a potential diagnostic and prognostic biomarker through regulation of tumor metastasis in PDAC patients.
