Title |
ERα E2 rep3 |
Sample type |
SRA |
|
|
Source name |
MCF7 breast cancer cells
|
Organism |
Homo sapiens |
Characteristics |
cell type: Human breast adenocarcinoma cell line: MCF7 passages: 20-30 chip-seq antibody: ERα HC-20 (sc543 from Santa Cruz, 1 µg used)
|
Treatment protocol |
After 2 days of hormone deprivation, MCF7 cells were treated with 30 minutes of 150 nM JQ1 treatment prior to 10 nmol/L 17-β-estradiol (Sigma-Aldrich) treatment for 2 hours. DMSO and vehicle were added as negative controls.
|
Growth protocol |
MCF7 cells were grown in phenol red- free high-glucose Dulbecco's Modified Eagle's Media (DMEM; Invitrogen) with 10% bovine growth serum (Thermo Scientific). For estrogen induction experiments, after one day of cell-splitting, the media was changed to DMEM containing 5% charcoal-dextran treated FBS (Sigma).

Extracted molecule |
genomic DNA |
Extraction protocol |
Cells were crosslinked with 1% Formaldehyde for 10 or 20 minutes and quenched with 125 mM Glycine. The nuclear pellets were sonicated to the fragment range of 200-400 bp. Sonicated extracts were incubated with specific antibodies at 4˚C overnight and ChIP-immune complexes were pulled down using Protein A sepharose. Library preparations were done using NEBnext Ultra DNA library preparation kit according to the manufacturer’s instructions.

Description |
Cells were crosslinked with 1 % formaldehyde for 10 minutes.
|
Data processing |
The reads were mapped to the human reference genome (UCSC HG19) using Bowtie (version 1.0.0) (Langmead et al., 2009). Peak-calling was done by Model based analysis of ChIP-seq (MACS version 1.4.2) (Zhang et al., 2008). Coverage was normalized on the total number of mapped reads per hundred million.
