For miRNA qRT-PCR the miScript SYBR® Green PCR Kit (Qiagen) and for mRNA the SYBR® Green PCR Master Mix (Applied Biosystems®) was used. In both instances, the manufacturer’s instructions were followed. Each cDNA sample was tested in duplicate (as in comparable studies24 (link)–26 (link) and dCT was determined by normalization of the Ct value to the Ct value of the reference small nucleolar RNA SNORD61 (Qiagen) for miRNA or to beta-actin (Invitrogen, Carlsbad, USA) for mRNA. Data were transformed into relative values by calculating: 2−ΔΔCT (ddCT) as previously described23 (link).
