| Sample type |
SRA |

|
| Source name |
VCaP cells
|
| Organism |
Homo sapiens |
| Characteristics |
cell line: Vertebral Cancer of Prostate (VCaP)
origin: bone metastasis of prostate cancer
antibody: rabbit antiserum against AR
treatment: 10nM R1881
time: 30min
|
| Treatment protocol |
Steroid-depleted medium (DMEM containing 2.5% charcoal-stripped FBS) was changed to the cells 3 days before exposing the cells to vehicle (EtOH) or R1881 (10 nM) for both GRO-seq samples and ChIP-seq samples.
|
| Growth protocol |
The cells were grown in DMEM containing 10% (v/v) defined FBS, 25 U/ml penicillin and 25 mg/ml streptomycin in a 5% CO2 atmosphere at 37 C incubator.
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
Lysates were derived from sonicated (Bioruptor, Diagenode) nuclei and AR-, CTCF- and H3K9me3-DNA complexes were isolated with 1 microgram of antibody and protein-A magnetic beads.
DNA fragments were purified and libraries were prepared for sequencing using standard Illumina protocol. Samples were deep-sequenced with HiSeq2000 at the GeneCore in EMBL (Heidelberg, Germany).

processed data file: VCaP_AR_R1881_30min_rep1+2_peaks.bed
|
| Data processing |
The quality of raw reads was analyzed by FastQC and FASTX-toolkit was used for preprocessing raw reads (removal of artifacts, trimming reads, quality filtering and collapsing identical reads).
Reads were aligned against human genome hg19 with Bowtie software (0.12.7) with the command line: -v 1 -k 1 -m 1 -f -S --best hg19.
The ChIP-seq peak detection was done by using HOMER software (V 4.7.2; http://homer.salk.edu/homer/)). Binding sites were determined with findPeaks command (using -factor mode and IgG sample as a background). BedGraph file was done by combining two replicates and normalizing total number of reads to 10 million. GRO-seq analysis were done by using HOMER software (V 4.7.2) to determine the gene expression with analyzeRepeats command.
Genome_build: hg19
Supplementary_files_format_and_content: peaks.bed files contain information of the statistically significant peaks (found in both replicates). BedGraph file show signal intensities. Excel file of GRO-seq data show gene expression values.
