Extraction protocol |
Chromatin immunoprecipitation were performed as previously described (PMID: 19212405) with some modifications. Briefly, frozen tissue was pulverized with a mortar and pestle, resuspeneded in PBS, and cross-linked with 1% formaldehyde at room temperature for 10 min. Chromatin was sonicated to obtain fragments with an average size ranging between 100-600 bp. Chromatin was inclubated for 2h at 4 C with 5 µg of antibody. Protein A and G Dynabeads (Invitrogen) were then added to this chromatin/antibody mixture for 30 minutes at 4 C. Immuno-complexes were sequentially washed. The protein/DNA complexes were eluted in an SDS buffer (1% SDS, 50 mM Tris pH 8.0, 10 mM EDTA) at 37 C for one hour. Samples were treated with Proteinase K at 37 C and reverse-crosslinked overnight. Finally, the DNA was purified on Zymo ChIP clean and concentrate columns (Zymo Research) and the quality was assessed on the Agilent bioanalyzer. The ChIP-seq libraries were prepared using the Illumina TruSeq library preparation kit followed by sequencing on an Illumina HiSeq 2000.

Description |
Chromatin IP against H3K27ac
|
Data processing |
Single-end reads were obtained by quality filtering and adaptor trimming using cutadapt_v1.1 with parameter ‘-m 25 -q 20’ and were mapped to the reference genome NCBI37/hg19 using Bowtie version 2.0.2.0 (Langmead 2009) with parameter ‘-m 1 -v 2 -p 16’. Duplicates were removed with samtools and MACS (Zhang 2008) (version 1.4.2) with parameter ‘-mfold = 10,30 -nomodel -p 0.0001’ was used for peak calling. Assembly: hg19 Supplementary files format and content: Normalized bigWig files were generated using bedtools (bedGraphToBigWig). Supplementary files format and content: Peak files were generated using MACS (Zhang 2008).
