Sample GSM3110161 Query DataSets for GSM3110161
Status Public on May 31, 2018
Title siSA2_REP1
Sample type SRA
 
Source name Human Mammary Epithelial Cells
Organism Homo sapiens
Characteristics cell type: MCF10A -Transformed nontumorigenic
experiment: MCF10A cells were arrested in G1 by means of high confluency culture (150,000 cells per cm2). Hi-C was performed as described (Serra et al., 2017) using MboI enzyme. Two library replicates per condition were sequenced (>200 million reads each).
treatment: Cells were transfected with 50 nM onTARGETplus SMARTpool STAG2 siRNAs (Dharmacon L-021351) at seeding in high confluency using DharmaFECT reagent 1.
Growth protocol MCF10A cells were grown in DMEM/F12 supplemented with 20ng/ml of EGF, 0.5mg/ml hydrocortisone, 100ng/ml of cholera toxin, 10mg/ml of insulin and 5% of horse serum.
Extracted molecule genomic DNA
Extraction protocol Paired-end libraries were generated with Truseq adaptors (Illumina) according previously published Hi-C protocols (Rao et al., 2014).
 
Library strategy Hi-C
Library source genomic
Library selection other
Instrument model Illumina HiSeq 2500
 
Description Digested/Ligated genomic DNA
Data processing TADbit’s fragment based mapping module (aligning with GEM) with the default parameters was used to align reads. TADbit’s filtering module was used to filter out non-informative contacts (self-circle, dangling ends, extra-dangling ends, errors, duplicated and random breaks).
Contact matrices were obtained and poor bins (containing low counts) were filtered out using TADbit’s routines. Raw counts at 40kb and 100Kb resolution are stored as tab-separated files with bin in first column,  second bin as second column, and number of contacts as third column.
Genome_build: GRCh38
Supplementary_files_format_and_content: Raw interaction matrices per chromosome are included in the abc format, which has commented lines (start with a “#” character) and the actual interaction counts (one per line) as three column with left-bin, rigth-bin and raw-counts.
