Sample GSM5858325 Query DataSets for GSM5858325
Status Public on Jul 28, 2023
Title Hi-C siESCO1 replicate1
Sample type SRA
Source name RPE cells
Organism Homo sapiens
Characteristics enzyme: MboI
treatment: ESCO1 siRNA
time point: 72h
Treatment protocol RNAi transfection was performed using Lipofectamine RNAiMAX (Thermo Fisher Scientific) in accordance with the manufacturer's protocol, using final RNA duplex concentration of 50 nM.
Growth protocol RPE cells were routinely cultured in DMEM supplemented with penicilline-streptomycin-L-glutamine solution (Wako) and 10% FBS.
Extracted molecule genomic DNA
Extraction protocol Hi-C experiments were performed using MboI restriction enzyme as previously described (Rao, S. S. et al. A 3D map of the human genome at kilobase resolution reveals principles of chromatin looping. Cell 159, 1665-1680, doi:10.1016/j.cell.2014.11.021 (2014)). Briefly, RPE cells were crosslinked with 1% formaldehyde for 10 min at room temperature. Cells were permeabilized and chromatin was digested with MboI restriction enzyme, and the ends of restriction fragments were labeled with biotinylated nucleotides and ligated. After crosslink reversal, DNA was purified and sheared with Covaris M220 (Covaris). Then point ligation junctions were pulled down with streptavidin beads.
Sequencing libraries were constructed using Nextera Mate Pair Sample Preparation Kit (Illumina) according to the manufacturer’s protocol with 15 PCR cycles.

Data processing Sequenced paired-end 150-bp reads were mapped to the human genome hg38 using Juicer version 1.5.7 (BWA 0.7.12-r1039) with default parameters.
Genome_build: UCSC hg38
Supplementary_files_format_and_content: The hic files were generated by juicertools version 1.9.9 with default parameters. We used "inter_30.hic" in which low-quality reads were filtered.
