Sample GSM4407559 Query DataSets for GSM4407559
Status Public on Feb 23, 2021
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).
 
Library strategy OTHER
Library source genomic
Library selection other
Instrument model Illumina HiSeq 2500
 
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
