|
| Source name |
breast
|
| Organism |
Homo sapiens |
| Characteristics |
tissue: breast
cell line: MCF10A
cell type: epithelial
treatment: mock transfection
|
| Treatment protocol |
MCF10A cells were transfected with 50 nM siRNAs using DharmaFECT reagent 1 and Gibco Opti-MEM I Reduced Serum Media and harvested 72h later.
|
| Growth protocol |
MCF10A cells are 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 |
MCF10A cells (3 mill cells per condition) were fixed with 2% formaldehyde (Sigma, #252549) in PBS with 10% FBS for 10 min. Formaldehyde was quenched with 300 mM of glycine at RT for 5 minutes. Hi-C experiments were performed with Arima-HiC Kit (A510008) following manufacturer’s instructions.
Libraries were prepared with Swift Biosciences Accel-NGS 2S Library Kit (Cat# 21024) and amplified with KAPA Library Amplification Kit (KAPA Cat# KK2620). For all the libraries, 8-9 PCR cycles were used for amplification and they were then sequenced on an Illumina NextSeq550 (82x43 bp).

| Data processing |
Alignment of sequences to the reference human genome (hg19) was performed using ‘Bowtie2′ with --local --reorder flags.
To assess the reproducibility of the replicates, 5-kb raw matrices were summed to obtain 40-kb matrices and these were normalized first by coverage and then by KR algorithm.
Given the high correlation of the distribution of contacts as a function of genomic distance among replicates for each condition (control or KD), replicates were merged and analyzed at 5-kb resolution
Assembly: hg19
