Sample GSM1374095 Query DataSets for GSM1374095
Status Public on Jan 01, 2016
Title IRP2 immunoprecipitation from cells treated with DFO, replicate 2
Sample type SRA
 
Source name human bronchial epithelial cells (Beas2B cells)
Organism Homo sapiens
Characteristics antibody: Irp2 (7H6: sc-33682, Santa Cruz)

Treatment protocol Beas2B cells were treated with 10 μM DFO (16 h) (15 cm2 dishes) and were washed with ice cold PBS and collected into 2 ml eppendorfs by scraping.
Growth protocol Beas2B cells were seeded into 15cm2 dishes and left overnight.
Extracted molecule total RNA
Extraction protocol Trizol extraction of total RNA was performed according to the manufacturer's instructions.
Samples were prepared for RNA-Seq using the TruSeq RNA-Seq Lib Prep Reagent (Illumina)
 
Library strategy RIP-Seq
Library source transcriptomic
Library selection other
Instrument model Illumina HiSeq 2000
 
Description DFO12vsCTRL12_Peaks_LowFilter.txt (peak calls comparing IRP2 immunoprecipitation in DFO versus CTL treatments)
SC2_DFO_12_Peaks_LowFilter.txt (peak calls comparing IRP2 and IGG immunoprecipitation)
Data processing Sequenced readswere aligned to the human hg19 known transcriptome using bowtie2-2.0.6 and tophat-2.0.7.Linux_x84_64. Any unmapped reads were then allowed to map to the hg19 genome.
Aligned reads from replicates were combined using the 'merge' function in samtools-0.1.18, creating one bam file each for CONTROL, CONTROL IGG, DFO and DFO IGG
the 'findPeaks' function in homer v4.4 (style=factor) was used to to call peaks with a two-fold tag enrichment in a given 'samples' relative to a given 'control' and a Poisson p-value less than 0.1
Peaks common between multiple comparisons were identified with the 'mergePeaks' function in homer v4.4
Peaks were mapped to hg19 genes using the 'annotatePeaks' function in homer v4.4.
Peaks with a homer "peak-score" greater than 5 were retained for further analysis.
