Abstract

Background & aim: MicroRNAs associated with the Notch pathway play a critical role in the progression of pancreatic carcinoma. Our aim was to study the clinical significance of miR-107 and NOTCH2 in pancreatic ductal adenocarcinoma (PDAC). Methods: The circulating miR-107 levels in PDAC and controls were determined by qPCR. NOTCH2 protein (target) expression in tissue of PDAC, periampullary carcinoma, chronic pancreatitis and normal pancreatic tissue was assessed by immunohistochemistry. Results: The circulating miR-107 levels were found to be significantly reduced in PDAC as compared with controls. Additionally, NOTCH2 protein expression was higher in PDAC tissue as compared with controls and was clinically associated with metastasis. Conclusion: Our findings demonstrate the utility of circulating miR-107 as a potential differentiating marker in PDAC.
