| Title |
MCF7-4HT ATAC-seq |
| Sample type |
SRA |
| |
|
| Source name |
MCF7 cells
|
| Organism |
Homo sapiens |
| Characteristics |
cell line: MCF7
treatment: 2 uM 4-hydroxytamoxifen(4-HT)
|
| Treatment protocol |
1.Final concentration of 20 ng/mL TNF-α was added into the cell culture medium and HeLa cells were incubated in 37 °C for 15 min, 30 min and 60 min. Cells were harvested in cold 1x PBS buffer and counted.
2.When the density of MCF7 cells was up to 70%, DMEM was changed to Phenol Red-free DMEM with 2.5% FBS for 24 h and then Phenol Red-free DMEM only for 24 h. Final concentration of 100 nM 17β-estradiol(E2) and 2 uM 4-hydroxytamoxifen(4-HT) were added into the cell culture medium, cells were incubated in 37 °C for 2 h. Cells were harvested in cold 1x PBS buffer and counted.
|
| Growth protocol |
Human cell lines HeLa, HepG2 and MCF-7 were maintained in Dulbecco’s Modified Eagle’s Medium (DMEM) supplemented with 10% fetal bovine serum (FBS) and Pen-Strep (100 U / ml penicillin, 100 mg / ml streptomycin) at 37℃, 5% CO2. Mouse C2C12 were cultured in DMEM supplemented with 10% FBS, 2 mM -glutamine, 100 U/ml penicillin and 100 g of streptomycin (1% Pen/Strep) at 37℃, 5% CO2. For myogenic differentiation, cells were shifted to DMEM containing 2% horse serum (differentiation medium).

| Extracted molecule |
genomic DNA |
| Extraction protocol |
Cells were harvested and wash once with cold 1x PBS buffer, and then resuspended in 1 mL cold lysis buffer (10 mM Tris-HCl, pH 7.4, 10 mM NaCl, 3 mM MgCl2, 0.1% NP-40, 1mM PMSF). This cell lysis reaction was incubated on ice for 10 min.
DNA libraries were prepared for sequencing using TruePrepTM DNA Library Prep Kit V2 for Illumina.

| Description |
4HT_FKDL190738026-1a
|
| Data processing |
Illumina Casava1.7 software used for basecalling.
Sequenced reads were trimmed for adaptor sequence, and masked for low-complexity or low-quality sequence, then mapped to hg19 or mm10 whole genome using bowtie2 v2.2.6 with parameters with the parameters -X2000 and -m1.
Remove mitochondrial DNA with removeChrom.py
Peak calling with macs2 v 2.2.1
Motif finding with homer(findMotifsGenome.pl)
Genome_build: hg19 and mm10
Supplementary_files_format_and_content: narrowPeak files were generated using macs2
