RNA was extracted using RNeasy micro plus kit from Qiagen Quality and integrity of total RNA was controlled on Agilent Technologies 2100 Bioanalyzer (Agilent Technologies; Waldbronn, Germany). The RNA sequencing library was generated from 500ng total RNA using Dynabeads® mRNA DIRECT™ Micro Purification Kit (Thermo Fisher) for mRNA purification followed by NEBNext® Ultra™ II Directional RNA Library Prep Kit (New England BioLabs) according to manufacture´s protocols. The libraries were sequenced on Illumina NovaSeq 6000 using NovaSeq 6000 S1 Reagent Kit (100 cycles, paired end run) with an average of 5 x107 reads per RNA sample.
