Sample GSM2040043 Query DataSets for GSM2040043
Status Public on Oct 24, 2016
Title MCF7_ChIP_ERa_sc543x_NA_E2_100nM_120min_Rep1
Sample type SRA
Source name MCF7-E2-CHIP-ERA
Organism Homo sapiens
Characteristics cell line: MCF7 (ATCC, HTB-22)
cell type: Breast adenocarcinoma-derived cells
passages: N/A
treated with: 100nM E2, 120min
chip antibody: Era (Santa-Cruz, sc543x, lot:
Treatment protocol For EtOH treatment, 250 ul of 1% EtOH were added directly to cell medium (25 ml) and incubated for 1 hour at 37C. For estradiol treatment, 100nM of Beta-Estradiol (SIGMA, E8875) was added directly to cell medium and incubated for two hours at 37C.
Growth protocol HEPG2 were grown in DMEM (Gibco, 11965-092) and A549 were grown in F12K medium (Gibco, 21127022) as recommended by the supplier. All cell mediums were supplemented with 10% fetal bovine serum (Invitrogen, qualified 12483020), 100 μM MEM nonessential amino acids (Cellgro, 25-0250), 2 mM L-glutamine (Gibco, 25030-081), 100 U/ml penicillin, 100 μg/ml streptomycin (Gibco, 15170-063). MCF7 were kept in DMEM w/o phenol-red (Gibco, 31053-028) supplemented with 5% of Charcoal/Dextran treated FBS (Hyclone, AVH78911), 100 μM MEM nonessential amino acids (Cellgro, 25-0250) and 2 mM L-glutamine (Gibco, 25030-081) for 3 days prior to 100nM of Beta-Estradiol (SIGMA, E8875) for two hours.
Extracted molecule genomic DNA
Extraction protocol Cells were crosslinked with 1% formaldehyde in culture medium for 10 minutes at room temperature. Cells were then lysed in 10 ml lysis buffer (0.1%SDS, 1% Triton X-100, 2mM EDTA, 20mM Tris-HCl ph 8.0 and 150 mM NaCl) and chromatin was sheared to 200-600 bp fragments using a Bioruptor Sonicator (Diagenode). Chromatin extract from 5x10^7 cells was incubated overnight at 4oC with 100 ul of Dynabeads Protein G magnetic beads (Life Technologies, 10004D) previously incubated with 10 ug of selected antibodies. After ChIP, samples were washed and bound complex were reversed cross-linked and eluted in 10mM Tris-HCl pH 8
The TruSeq DNA sample prep kit with indexing adapters was used according to the manufacturer's recommendations (Illumina)
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina HiSeq 2000
Description MCF7-E2-CHIP-ERA-rep1
Data processing All datasets were analyzed with the ChIP-Seq pipeline developed at the McGill University and Génome Québec Innovation Centre ( (version 2.1.0)
All samples were processed using Trimmomatic 0.33 with the following parameters: LEADING=30, TRAILING=30, SLIDINGWINDOW=4:30, MINLEN=30. Reads were mapped against the hg19 build of the human reference genome using BWA 0.7.12 with default parameters and MACS2 2.1.0 with default parameters was used for peak calling.
Genome_build: hg19
Supplementary_files_format_and_content: NarrowPeak files were generated with MACS2 2.1.0 with default parameters. The enrichment ratio of each replicate were calculated with the 2 control files available for each cell line.
