Status Public on Aug 13, 2021
Title TS53_ATAC_KD
Sample type SRA
 
Source name Fujioka cells
Organism Homo sapiens
Characteristics cell line: Fujioka
agent: lentivirus targeting FOXC1
Treatment protocol Cultured in RPMI 1640 medium (Sigma Aldrich) supplemented with 2mM L-Glutamine (Life Technologies) and 10% fetal bovine serum (Sigma Aldrich).
Growth protocol Cultured in RPMI 1640 medium (Sigma Aldrich) supplemented with 2mM L-Glutamine (Life Technologies) and 10% fetal bovine serum (Sigma Aldrich).
Extracted molecule genomic DNA
Extraction protocol 10^8 cells were used for each precipitation using the method described by Lee et al. (2006). Briefly, cells were cross-linked with 1% formaldehyde for 10 minutes at room temperature before the reaction was quenched with 0.125M glycine. Cell pellets were washed twice with PBS and nuclear lysates sonicated for 6 cycles using a Bioruptor® Pico (Diagenode, Liege, Belgium). 10μg of antibody bound to 100μl of magnetic beads (Dynabeads Protein G, Invitrogen, Carlsbad, CA) was added to each sample and immunoprecipitation performed overnight on a rotator at 4°C and 20rpm. After five washes with RIPA buffer (50mM HEPES pH 7.6, 1mM EDTA, 0.7% Na deoxycholate, 1% NP-40, 0.5M LiCl), chromatin IP-bound fractions were extracted by incubating for 15 min at 65°C with elution buffer (50mM TrisHCl pH8, 10mM EDTA, 1% SDS). Crosslinking was then reversed by incubation at 65°C for 6 hours. RNaseA (1mg/ml) and proteinase K (20mg/ml) were added to eliminate RNA and protein from the samples. DNA was extracted using phenol:chloroform:isoamyl alcohol and precipitated by adding 2 volumes of ice-cold 100% ethanol, glycogen (20μg/μl), 200mM NaCl and freezing at -80°C for at least 1hr. Pellets were washed with 70% ethanol and eluted in 50μl 10mM TrisHCl pH8.0.
Libraries were prepared for sequencing using a Microplex Library Preparation Kit (Diagenode). 200-800bp fragments were selected using AMPure beads (Beckman Coulter, Brea, CA) and quantified by qPCR with a KAPA Library Quantification Kit (Kapa Biosystems, Basel, Switzerland). Sequencing was performed using a NextSeq desktop sequencing system (Illumina) with 75bp, paired-end high output generating 65-80M reads per sample.

Data processing Reads were aligned to the human genome (hg38) using BWA-MEM v0.7.15 (5). Read duplicates were removed using Picard v2.1.0. Reads were further filtered using Bedtools v2.25.0 to keep only paired reads that mapped to standard chromosomes and to remove reads with a mapping quality of less than 10. Reads mapped to blacklisted regions defined by ENCODE were then removed using Bedtools (http://mitra.stanford.edu/kundaje).
