Title |
ChIP RHOX11-HA |
Sample type |
SRA |
|
|
Source name |
NIH-3T3
|
Organism |
Mus musculus |
Characteristics |
cell line: NIH-3T3 cell type: mouse fibroblasts chip antibody: Anti-HA.11 IgG (901501)
|
Treatment protocol |
NIH-3T3 cells were treated overnight with 500 ng/ml of Doxycycline one day after seeding. ChIP-seq was performed on at least 10 million cells.
|
Growth protocol |
NIH-3T3 cells were routinely cultured at 37°C and 5% CO2 in DMEM, supplemented with 10% fetal bovine serum and 1% penicillin/streptomycin. Cells were grown in 100 mm cell culture dishes up to a confluence of 90% and split 1:6 every 3-4 days.

Extracted molecule |
genomic DNA |
Extraction protocol |
Cells were fixed with 1% formaldehyde for 10 minutes at room temperature and quenched with 200 mM Tris-HCl pH 8.0, washed with PBS, spun down, and stored at -80°C. The cell pellet was resuspended and in 1.5 ml LB1 (50 mM HEPES-KOH pH 7.4, 140 mM NaCl, 1 mM EDTA, 0.5 mM EGTA, 10% Glycerol, 0.5% NP40, 0.25% Triton X-100), incubated 10 min at 4°C, spun down, and resuspended in 1.5 ml LB2 (10 mM Tris-HCl pH 8.0, 200 mM NaCl, 1 mM EDTA, 0.5 mM EGTA) incubated 10 min at 4°C. The pellet was spun down, rinsed twice with SDS shearing buffer (10 mM Tris-HCl pH 8.0, 1 mM EDTA, 0.15% SDS), and finally resuspended in 0.9 ml SDS shearing buffer. All buffers contain contain 1:100 diluted Protease Inhibitor Cocktail in DMSO (Sigma). The suspension was transferred to a milliTUBE 1 ml AFA fiber and sonicated on a E220 focused ultrasonicator (Covaris) using the following settings: 20 min, 200 cycles, 5% duty, 140W, and input sample aliquots were taken. To pull down HA-bound DNA, sonicated chromatin was incubated with anti-HA.11 antibody 16B12 (BioLegend) overnight at 4°C. 2.5 ml Protein G Dynabeads (Thermo Fischer) per one million cells were added to the chromatin and incubated 3 hours at 4°C. The chromatin was washed several times at 4°C with 5 min incubation between each wash and 2 min magnetization to collect beads; twice with Low Salt Wash Buffer (10 mM Tris-HCl pH 8.0, 150 mM NaCl, 1 mM EDTA, 1% Triton X-100, 0.15% SDS, 1 mM PMSF), once with High Salt Wash Buffer (10 mM Tris-HCl pH 8.0, 500 mM NaCl, 1 mM EDTA, 1% Triton X-100, 0.15% SDS, 1 mM PMSF), once with LiCl Wash Buffer (10 mM Tris-HCl pH 8.0, 1 mM EDTA, 0.5 mM EGTA, 250 mM LiCl, 1% NP40, 1% sodium deoxycholate, 1 mM PMSF), and finally with TE buffer (10 mM Tris-HCl pH 8.0, 1 mM EDTA, 1 mM PMSF). Beads were finally resuspended in Elution buffer (TE buffer with 1% SDS and 150 mM NaCl), treated with 400 ng/ml Proteinase K and reverse crosslinked at 65°C 1100 rpm overnight. Input samples were treated with 100 mg/ml RNase A and 400 ng/ml Proteinase K and reverse crosslinked at 65°C 1100 rpm overnight. Sonicated chromatin samples were purified using Qiagen MinElute PCR purification kit. Libraries were prepared with NEBNext ChIP-seq Library Prep Master Mix kit with insert size selection of 250 bp.

Description |
Overexpression of RHOX11-HA
|
Data processing |
Reads were aligned to the mouse reference genome mm10 using STAR 2.5.3a with settings ‘-- alignMatesGapMax 2000 --alignIntronMax 1 --alignEndsType EndtoEnd -- outFilterMultimapNmax 1’ Duplicate reads were removed with Picard and reads not mapping to chromosomes 1-19, X, or Y were removed Peaks were called with MACS 2.1.1.20160309 with settings ‘-f BAMPE -g mm’. Peaks overlapping peaks called for input (non-immunoprecipitated chromatin) from NIH- 3T3 cells and ENCODE blacklisted peaks were discarded. Genome_build: mm10 Supplementary_files_format_and_content: bigWig files were generated with deepTools 2.4.2 with settings '--normalizeUsingRPKM'
