miRNAs were isolated from serum by the miRNeasy Serum/Plasma Advanced Kit and from ECs by MasterPure Complete DNA & RNA Purification Kit (Lucigen), retrotranscribed using the miRCURY LNA RT Kit, and quantified by qPCR with the miRCURY LNA SYBR Green PCR Kit (all from Qiagen) as their protocols indicate. Specific primers (Qiagen) were used to measure miRNAs of interest, and the 2‐ΔΔCT method was applied to quantitate the different data15 (link) obtained in the LightCycler 96 Real‐Time PCR System (Roche Life Science).
