Reverse transcription polymerase chain reaction dissociation curves of microRNAs in sera of patients with pancreatic adenocarcinoma. Circulating U6 (A), miR-17-5p (B) and miR-21 (C) miRNAs were specifically amplified with a singular peak in the dissociation curve. The variation in the dissociation curves of miR-155 (D) and miR-196a (E) indicated negative expression.
