Title |
H3K27Ac_shEts1_3-1 |
Sample type |
SRA |
|
|
Source name |
THP-6 T-ALL cell line
|
Organism |
Homo sapiens |
Characteristics |
cell line: THP-6 T-ALLs transduction: Ets1-silencing shRNA disease: T lymphoblastic leukemia/lymphoma cell type: T lymphocyte antibody: H3K27ac (Active Motif, pAb 39133 )
|
Treatment protocol |
THP-6 T-ALL cells were lentivirally transduced with pLKO.1-type shRNA for 2 days and then selected with puromycin for 2 days prior to harvesting.
|
Growth protocol |
T-ALL cell lines were grown in RPMI 1640 (Invitrogen) supplemented with 10% fetal bovine serum (Hyclone or Gibco), 2 mM L-glutamine, 2-mercaptoethanol (0.0005% (v/v), Sigma), penicillin and streptomycin.

Extracted molecule |
genomic DNA |
Extraction protocol |
Cells were crosslinked for most samples by addition of 1% formaldehyde to media at 37 C for 10 minutes, followed by glycine quenching and 2x washing in PBS. For Ets1, Cells were crosslinked with 2 mM DSG and 1% formaldehyde. For H3K27ac, cells were crosslinked with 1% formaldehyde at room temperature. Nuclei were isolated by hypotonic buffer lysis, and chromatin was fragmented with a QSonica Q800 bath sonicator in 0.3% SDS-containing lysis buffer. Samples were diluted 1:3.3 and chromatin complexes containing the target of interest were isolated by immunoprecipitation, followed by reverse crosslinking and DNA purification by SPRI. For input samples, 1:8diluted sonicated chromatin (whole cell extract; wce), was added directly to the reverse crosslinking step without immunoprecipitation. Purified ChIP or input DNA was end-repaired and A-tailed. Illumina barcoded adaptors were ligated and PCR amplified. Final library was isolated by double SPRI purification (sequential reverse and forward SPRI) and paired-end sequenced (38 bp x 2) on illumina NextSeq.

Data processing |
ChIP-Seq: Reads were aligned to the hg19 genome assembly using bwa-aln and bwa-sampe (bwa version 0.7.12) Genome_build: hg19 Supplementary_files_format_and_content: ChIP-Seq: Data were filtered to remove PCR duplicates and reads mapping to >2 genomic sites. Then bigwig display files were generated with deepTools bamCoverage and UCSC wigToBigWig, and bed peak files were generated with Homer findPeaks (“style -factor” for transcription factors and “style -histone” for H3K27ac).
