  • Title: A Circulating MicroRNA Panel for Malignant Germ Cell Tumor Diagnosis and Monitoring.
    Author: Murray MJ, Scarpini CG, Coleman N.
    Journal: Methods Mol Biol; 2021; 2195():225-243. PubMed ID: 32852767.
    Abstract:
    Reverse transcription (RT) based quantitative PCR (qPCR) for quantifying microRNAs (miRNAs) in in the circulation presents specific challenges. Here, we describe an optimized research protocol to assess serum sample quality and quantify levels of a panel of four test miRNAs (miR-371a-3p, miR-372-3p, miR-373-3p, and miR-367-3p) that enables highly sensitive and specific malignant germ cell tumor (GCT) diagnosis and monitoring. This protocol utilizes a multiplex RT step using Taqman miRNA stem-loop primers. A multiplexed preamplification stage is then employed to increase the sensitivity of the final quantification step, which is performed using standard singleplex Taqman qPCR methodology.
