|
| Source name |
breast cancer cells
|
| Organism |
Homo sapiens |
| Characteristics |
cell line: MCF7
growth protocol: control (parental cell)
|
| Growth protocol |
MCF7 parental cells were maintained in RPMI/1640 supplemented with 10% heat-inactivated FBS (Sigma) and 1% penicillin-streptomycin (P/S). The TamR cells were kept in phenol-red free RPMI/1640 medium supplemented with 10% heat-inactivated charcoal-stripped-FBS and 1% P/S with the addition of 100 nM 4-hydroxytamoxifen (4-OHT, H7904, Sigma). All cells were kept at 37 °C in a humified incubator with 5% CO2.

| Extracted molecule |
genomic DNA |
| Extraction protocol |
50,000 cells were harvested for each condition. After purification of nuclei, transposition was performed with Tn5 transposase from Nextera DNA Library Prep Kit (Illumina, catalog # FC-121-1030). ATAC-seq library prep was performed as in Buenrostro et al, 2015. Libraries were sequenced with Mid 75bp PE on Illumina NextSeq 500 (4 samples in one lane).

| Description |
MCF7_full media_ATAC-seq
|
| Data processing |
Basecalls performed using Illuminal CASAVA software.
The adaptor was removed by using cutadapt v1.11 with parameters "-m 20 -e 0.1". The clean reads were aligned to the hg19 genome assembly using bowtie2 v2.2.9 with parameters "-mm --very-sensitive --no-discordant -X 2000", and only primary alignments were retained. The alignments were shifted with +4 for plus strand and -5 for minus strand.
Peaks were called using MACS2 with q-value less than 1e-5. The peaks overlapped with the blacklist regions downloaded from UCSC were removed
