Sample GSM2516776 Query DataSets for GSM2516776
Status Public on Sep 30, 2017
Title CHL1_BRD4_D4_01
Sample type SRA
 
Source name melanoma cancer cell line CHL-1
Organism Homo sapiens
Characteristics cell line: CHL-1
tumor type: melanoma
tissue: skin
chip antibody: anti-BRD4 (Bethyl Labs, A301-985A100)
Treatment protocol CHL-1 cells were treated for 4 hr with 500 nM BAY 1238097, OTX-015, or DMSO
Growth protocol CHL-1 melanoma cells were obtained from the American Type Culture Collection (ATCC) and were routinely grown DMEM medium in the presence of 10% (v/v) fetal calf serum (Life Technologies) at 37 °C and in 5% CO2 atmosphere.
Extracted molecule genomic DNA
Extraction protocol One 15 cm cell culture dish with 80% confluent cells was used per IP. ChIP DNA preparation for sequencing was carried out as described previously in Nagarajan et al. (Cell Rep. 2014 Jul 24;8(2):460-9) with the following changes: cross-linked chromatin was sheared to 200-800 base pair fragments using sonication (30 sec on/30 sec off, high power, 2 x 7.5 minutes with a water bath change between the two cycles) in a Biorupter sonicator UCD-200. 1.5 µg antibodies (anti-BRD4 [Bethyl Labs, A301-985A100]; anti-H3K27ac [Diagenode, C15410174]) were used per IP. DNA was purified using a PCR purification kit (Qiagen)

Description D4=BAY123897
Data processing paired-end genome wide sequencing data were aligned to the human reference genome (assembly hg19) using Bowtie2 software and sorted and indexed using SAMtools
Peak calling was done using the Model-bases analysis for ChIP-seq (MACS2) software. Broad peaks from H3K27Ac were called using MACS2 broad mode. MACS2 was used to generate enrichment pileups (log likelihood ratio (logLR)) of treatment vs. input control samples. A pseudocount of 0.00001 was added to avoid log10(0) during logLR calculation.
ChIP-seq tracks were generated using the Integrative Genomics Viewer software (Thorvaldsdottir et al. 2013). Heatmaps and line plots were generated using the seqplots software (http://przemol.github.io/seqplots).
