Direct Detection of miR-122 in Hepatotoxicity Using Dynamic Chemical Labeling Overcomes Stability and isomiR Challenges López-Longarela, B Morrison, EE Tranter, JD Chahman-Vos, L Léonard, JF Gautier, JC Laurent, S Lartigau, A Boitier, E Sautier, L Carmona-Saez, P Martorell-Marugan, J Mellanby, RJ Pernagallo, S Ilyine, H Rissin, DM Duffy, DC Dear, JW Diaz Mochon, Juan José Circulating microRNAs serve as stable and cross-species biomarkers. MicroRNA-122 (miR-122) is a reliable hepatocyte-specific biomarker for drug-induced liver injury (DILI). We developed a dynamic chemical labeling (DCL) assay enabling direct detection of miR-122 in blood, with high specificity and sensitivity from small sample volumes. This assay accurately identifies DILI in humans and animals, offering improved stability and isomiR detection compared to PCR methods. 2024-02-07T13:22:31Z 2024-02-07T13:22:31Z 2020-02-18 journal article López-Longarela B, Morrison EE, Tranter JD, Chahman-Vos L, Léonard JF, Gautier JC, Laurent S, Lartigau A, Boitier E, Sautier L, Carmona-Saez P, Martorell-Marugan J, Mellanby RJ, Pernagallo S, Ilyine H, Rissin DM, Duffy DC, Dear JW, Díaz-Mochón JJ.
