“…As mentioned in the Introduction, we found nineteen previous studies reporting on extracellular miRNAs associated with PE, with limited overlap in identified miRNAs among studies ( Table 1 ). 17 – 35 These studies can be divided into twelve discovery studies, which used large qRT-PCR panels, microarrays, or small RNA-seq, 18 , 22 , 23 , 27 – 35 and seven targeted studies, which performed qRT-PCR on small numbers of selected miR-NAs, 17 , 19 – 21 , 24 – 26 most commonly members of the placenta-specific miRNA cluster located at chr19q13 (C19MC). 19 – 21 , 24 , 25 Eleven C19MC miRNAs were identified in four of the discovery studies (the other eight discovery studies did not identify any C19MC miRNAs), 29 , 30 , 33 , 34 but only three specific miRNAs were shared among at least two studies: hsa-miR-517c-3p and hsa-miR-518e-3p were shared between Yang et al 33 and Yang et al, 34 and hsa-miR-519a-3p was common to Yang et al 33 and Timofeeva et al 29 ( Table S1 ).…”
