Sample GSM2759385 Query DataSets for GSM2759385
Status Public on Dec 20, 2017
Title input_CTCF_RAD21
Sample type SRA
Source name IMR-5
Organism Homo sapiens
Characteristics cell line: IMR-5
antibody: none
Treatment protocol For siRNA transfections, cells were transfected using the RNAiMAX reagent and OptiMem medium (LifeTechnologies) according to the manufacturer's instructions. Cells were harvested 48 h after transfection. Cells were treated with CD532 (1µM) or DMSO for 4 (ChIP-seq) or 4 and 8 (RNA-seq) hours.To activate N-MYC-ER in SH-EP cells, cells were treated with 4-OHT (200nM) for 5 hours. Conditional shRNA-mediated depletion of TFIIIC5 was induced with doxycycline (1 µg/ml) for 48 hours.
Growth protocol Neuroblastoma cells were grown in RPMI-1640 (Sigma). Medium was supplemented with 10% fetal calf serum (Biochrom) and penicillin/streptomycin (Sigma).
Extracted molecule genomic DNA
Extraction protocol Cells were treated with 1% formaldehyde for 10 min at 37 °C. After cell lysis, nuclei were re-suspended in RIPA buffer (10 mM Tris/HCl pH 7.5, 150 mM NaCl, 1% NP40, 1% deoxycholic acid (DOC), 0.1% SDS, 1 mM EDTA) and DNA was fragmented to a size <500 bp using a Branson sonifier. Chromatin was eluted with 1% SDS and crosslinking was reverted overnight. For purification, chloroform/phenol extraction was used.
Purified DNA was end-repaired, A-tailed, ligated to Illumina adaptors, size-selected (200 bp) and purified with Qiagen gel extraction kit. DNA fragments were amplified by 18 cycles of PCR and library size was tested with the Biorad Experion system. The amount of library DNA was quantified using a picogreen assay
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina NextSeq 500
Data processing Fastq files were generated using Illumina's CASAVA software and overall sequencing quality was analyzed with the FastQC script.
For ChIP-seq, fastq files were mapped to the human genome (hg19) using Bowtie v1.1.1. and normalized to the sample with the smallest number of mapped reads (10.8 million reads for TFIIIC5 and NMYC samples, 11 million reads for RNAPII samples, 51 million reads for CTCF and RAD21 samples).
Wiggle files were generated using MACS v1.4.2 with default parameters but a p-value cutoff of 1e-6 (N-MYC, TF3C5) and keep-dup parameter =1. .bedGraph files were generated using bedtools genomecov.
Genome_build: hg19
Supplementary_files_format_and_content: Fixed step wiggle files with a resolution of 10bp or bedgrpah files (
