Extracted molecule total RNA
Extraction protocol Mononuclear cell preparations were isolated from bone marrow or peripheral blood using Ficoll density gradient (Axis-shield). Next, Total RNA was extracted using the miRNeasy Mini Kit (Qiagen) in combination with on-column DNase I digestion (RNase-Free DNase set, Qiagen) according to manufacturer’s instructions. The quality of the extracted RNA was assessed using the RNA 6000 Nano and RNA 6000 PICO assays on an 2100 Bioanalyzer (Agilent).
Sequencing libraries were prepared using a TruSeq Stranded Total RNA Kit adapted for long fragments (+/- 550 bp) with the Ribo-Zero Gold rRNA Removal Kit (Illumina), according to the manufacturer’s instructions. Prepared libraries were run on a HiSeq3000 high-throughput sequencing system (Illumina) and paired end reads were generated (average of 52 million reads per sample)
 
Library strategy ncRNA-Seq
Library source transcriptomic
Library selection size fractionation
Instrument model Illumina HiSeq 3000
 
Description 7
Data processing Illumina Casava1.7 software used for basecalling.
Sequenced reads were trimmed for adaptor sequence, and masked for low-complexity or low-quality sequence, then mapped to hg38 reference genome using STAR v2.4.2 using a 2-pass strategy for identification of novel transcripts
Known gene quantification was performed on gencode v25 during the first pass.
Differential expression analysis of known genes was performed in R with DESeq2 v1.14.1
