Sample GSM3718108 Query DataSets for GSM3718108
Status Public on Feb 01, 2020
Title ChIPseq_LM_H3K27ac_REP2
Sample type SRA
 
Source name MDA-MB-231 breast cancer cell line lung metastatic variant
Organism Homo sapiens
Characteristics cell line: MDA-MB-231 LM2
cell type: mammary gland/breast epithelial cell
target molecule: H3K27ac
Growth protocol Cells were grown in monolayer in DMEM + 10% FBS + Penicillin-streptomycin at 37ÂșC, 5% CO2 for 3 days
Extracted molecule genomic DNA
Extraction protocol Cells were fixed in 1% formaldehyde for 10 min. Chromatin was prepared and immunoprecipitated as previously described (Greer CB, Tanaka Y, Kim YJ, Xie P, Zhang MQ, Park IH, Kim TH: Histone Deacetylases Positively Regulate Transcription through the Elongation Machinery. Cell Rep 2015, 13(7):1444-1455.).
DNA libraries were prepared using ThruPLEX DNA-seq Kit (Takara)
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina HiSeq 2000
 
Description MDAMB231_LM_H3K27ac_merge.mqsd.coverage.RPKM.bw
MDAMB231_Par_BoM_BrM_LM_H3K27ac_merge_peaks.broadPeak.unique.bed
MDAMB231_Par_BoM_BrM_LM_H3K27ac_merge_peaks.broadPeak.counts.txt
Data processing Basecalls performed using CASAVA version 1.8.2
Reads were trimmed of adapters using Trimmomatic v0.32
Trimmed reads were aligned using Bowtie2 v2.3.4.3 to hg19 using standard parameters and a maximum fragment length of 2000
Duplicate reads were determined using Picard tools v2.18.21
Bam files were filtered using samtools -F 1804
For consensus peak calling filtered bam files were merged. Peak calling was performed using MACS2 v2.1.2 with the option --broad.
Motif finding was performed using HOMER v4.10.
Reads that fell within consensus peaks were determined using featureCounts
DESeq2 was used to determine differential histone signal
Genome_build: hg19
Supplementary_files_format_and_content: bigwig (merge of replicates for each IP and input), bed (consensus peak for each IP), txt (DESeq2 results and raw counts)
