The microRNAs were analyzed by PCR using the Fluidigm platform.RESULTS: Twenty-two microRNAs were significantly differently expressed in patients with pancreatic cancer when compared to healthy controls and chronic pancreatitis patients; 17 miRNAs were upregulated (miR-21-5p, -23a-3p, -31-5p, -34c-5p, -93-3p, -135b-3p, -155-5p, -186-5p, -196b-5p, -203, -205-5p, -210, -222-3p, -451, -492, -614, and miR-622) and 5 were downregulated (miR-122-5p, -130b-3p, -216b, -217, and miR-375).
