Sample GSM2127464 Query DataSets for GSM2127464
Status Public on Sep 08, 2016
Title H3K27me3 DAC + EPZ6438 Be(2)-C
Sample type SRA
 
Source name Be(2)-C
Organism Homo sapiens
Characteristics cell type: neuroblastoma cell line
chip antibody: ab6002 (Abcam, Cambridge, UK)
Treatment protocol The neuroblastoma cell lines Be(2)-C and IMR5-75 were treated with a combination of DAC (1µM, 72h) and EPZ-6438 (1µM 96h) . Controls were treated with solvent (DMSO).
Growth protocol Cells were grown in RPMI medium (10%FCS) under standard conditions.
Extracted molecule genomic DNA
Extraction protocol Lysates were clarified from sonicated nuclei and histone-DNA complexes were isolated with antibodies. Antibodies against H3K27ac (ab4729), H3K4me3 (ab8580, Abcam) and H3K27me3 (ab6002, Abcam) were used for precipitation.
Library preparation was performed using the NEBNext Ultra DNA Library Prep Kit for Illumina (New England BioLabs, Ipswich, MA, US) according to the manufacturer’s protocol. Libraries were sequenced (50 bases single-end) on the Illumina sequencing platform (German Cancer Research Center Core facility).
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina HiSeq 2000
 
Data processing ChIP-seq single-end reads were aligned to the hg19 genome using Bowtie and only uniquely aligned reads were kept.
BAM-Files of aligned reads were further processed using the deepTools suite2. Input files were subtracted from the treatment files using the bamCompare tool, applying the SES method for normalization of signal to noise.
Resulting signals were normalized to an average 1X coverage to produce signal (bigWig) files.
