Sample GSM3103144 Query DataSets for GSM3103144
Status Public on Mar 26, 2019
Title IMR_DMSO_2
Sample type SRA
 
Source name IMR32 cells
Organism Homo sapiens
Characteristics cell line: IMR32
treatment: DMSO
cancer: Neuroblastoma
Treatment protocol Cells were incubated for 30min and 2 hours in the presence of DMSO or THZ531 (400nM) and labeled in media for 10 min with 500 μM 4-thiouridine before performing RNA extraction.
Growth protocol IMR-32 cells were grown in RPMI-1640 media supplemented with 10% fetal bovine serum and 1% penicillin/streptomycin
Extracted molecule total RNA
Extraction protocol RNA extraction was performed with TRIzol (Ambion) following the manufacturers’ instructions. Total RNA was treated with DNase I (Invitrogen). Subsequently, the purified RNA was fragmented on a BioRuptor Next Gen (Diagenode) at high power for one cycle of 30’’/30’’ ON/OFF.
Sequencing libraries were prepared with the RNA-seq library kit (TruSeq Stranded Total RNA RiboZero Gold, Illumina)
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina NextSeq 500

Data processing Paired-end 75bp reads were mapped to the human genome (GRCh38) concatenated with ERCC spike-in sequences using STAR (v2.5.1b) and default parameters.
Properly mapped reads were extracted using samtools (v1.3.1) and parameters “-q 7 and –f 83,99,147,163”.
Library size normalization was based on individual spike-in reads counted with samtools idxstats and used as input for estimateSizeFactorsForMatrix (DESeq2).
Strand specific coverage files were created with bamCoverage (DeepTools v2.5.4) with previously calculated sizefactors and parameters “--scaleFactor --normalizeUsingRPKM –filterRNAstrand –bs 100".
Biological replicates were merged using "samtools merge" and processed as described for the individual replicates.
Genome_build: GRCh38
Supplementary_files_format_and_content: bigWig coverage files for both individual replicates and merged replicates.
