Sample GSM2082065 Query DataSets for GSM2082065
Status Public on Dec 20, 2017
Title siCTR_rep4
Sample type SRA
Source name IMR-5
Organism Homo sapiens
Characteristics sirna: siCTR
cell line: IMR-5
Treatment protocol For siRNA transfections, cells were transfected using the RNAiMAX reagent and OptiMem medium (LifeTechnologies) according to the manufacturer's instructions. Cells were harvested 48 h after transfection. Cells were treated with CD532 (1µM) or DMSO for 4 (ChIP-seq) or 4 and 8 (RNA-seq) hours.
Growth protocol Neuroblastoma cells were grown in RPMI-1640 (Sigma). Medium was supplemented with 10% fetal calf serum (Biochrom) and penicillin/streptomycin (Sigma).
Extracted molecule total RNA
Extraction protocol Total RNA was isolated using RNeasy mini columns (Qiagen) including on-column DNase I digestion.
mRNA was extracted using the NEBNext® Poly(A) mRNA Magnetic Isolation Module (NEB). Library preparation was performed with the NEBNext® Ultra™ RNA Library Prep Kit for Illumina following the instruction manual. Size-selection of libraries was performed using Agencourt AMPure XP Beads (Beckman Coulter) followed by amplification with 12 PCR cycles. Afterwards libraries were quantified and the size was determinded using Experion Automated Electrophoresis System (Bio-Rad).
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina NextSeq 500
Data processing Fastq files were generated using Illumina's CASAVA software and overall sequencing quality was analyzed with the FastQC script.
For RNA-seq, reads were mapped to hg19 with Tophat2 and Bowtie1 with default settings.
Reads per gene were counted using the countOverlaps function from the R package {GenomicRanges}.
Weakly expressed genes were removed(mean count over all samples <1.5) and differentially expressed genes were called using EdgeR.
Genome_build: hg19
Supplementary_files_format_and_content: txt files containing Ensembl gene ID, gene symbol, gene description, log2FC, p-value and q-value (FDR) for all comparisons. A matrix file containing raw read counts for all samples.
For ChIP-seq, fastq files were mapped to the human genome (hg19) using Bowtie v1.1.1. and normalized to the sample with the smallest number of mapped reads.
Wiggle files were generated using MACS v1.4.2 with default parameters but a p-value cutoff of 1e-6.
Genome_build: hg19
Supplementary_files_format_and_content: Fixed step wiggle files with a resolution of 10bp.
