Title |
NG-Capture C siCTL rep2 |
Sample type |
SRA |
|
|
Source name |
MDA-MB-231 cell line
|
Organism |
Homo sapiens |
Characteristics |
cell line: MDA-MB-231 cell type: breast cancer cell line tumor type: triple negative - basal b knockdown: si control
|
Treatment protocol |
Cells were transfected with either a control siRNA (siCTL) or a mix of siRNAs directed against Fra-1 (siFra-1) (4.5nM of siRNAs for 72 hours) using INTERFERin, according to the manufacturer's instructions. Experiments were carried out in 3 independent replicates.
|
Growth protocol |
MDA-MB-231 cells (ATCC, Rockville, MD, USA) were cultured cultured in Dulbecco’s modified Eagle’s medium containing 10% fetal calf serum and penicillin/streptomycin (100µg/ml each) in a humidified 5% CO2 atmosphere at 37°C. Cells freshly amplified and frozen after obtention from the ATCC were used every 3months and were routinely tested for the absence of mycoplasma contamination

Extracted molecule |
genomic DNA |
Extraction protocol |
The experiments were performed as previously described in (Davies et al., 2016b). Briefly, 3C libraries were generated using 900 U of the Dpn II restriction enzyme (NEB: R0543M) for 11 million cells and 720 U of the T4 DNA HC ligase (Life Technologies: EL0013). 3C libraries were sonicated (Bioruptor® Pico sonication device; 5 cycles; 30s ON/OFF). Samples were indexed to allow multiplexing using Illumina paired-end sequencing adaptors (NEB: E6040, E7335) and the Herculase II polymerase (Agilent: 600677). Oligonucleotide capture was then performed using 70-mer biotinylated DNA oligonucleotides designed at each of the studied target gene promoters (http://apps.molbiol.ox.ac.uk/CaptureC/cgi-bin/CapSequm.cgi). The hybridization reaction was performed using Nimblegen SeqCap EZ kits (Roche: 05634261001, 07145594001, 06777287001). After a 72h hybridization step, streptavidin bead pulldown (Invitrogen: 65305) was performed, followed by multiple washes (according to SeqCap EZ SR user’s guide) followed by PCR amplification of the captured material. A second capture step was performed as above. Samples were indexed to allow multiplexing using Illumina paired-end sequencing adaptors (NEB: E6040, E7335) and the Herculase II polymerase (Agilent: 600677).

Description |
chimeric genomic DNA - 3C libraries

Data processing |
Library strategy: NG-Capture C Data were analyzed using scripts available at https://github.com/telenius/captureC/releases R was used to normalize data. Differential analysis between the siCTL and the siFra-1 condition was performed using DESeq2 Peak calling was performed using the PeakC R package (Geeven et al., 2018) using the following parameters: alphaFDR=0.1, wSize=5 and qWr=1. Adjacent restriction fragments called by PeakC were then merged into a single region using BEDTools Genome_build: hg19 Supplementary_files_format_and_content: bigWig files
