Sample GSM2723835 Query DataSets for GSM2723835
Status Public on Aug 22, 2017
Title A-498 empty vector input rep1
Sample type SRA
 
Source name ccRCC cell line
Organism Homo sapiens
Characteristics histone: Input
chip antibody: none
source: A-498 (ATCC HTB-44)
Treatment protocol 786-O cells stably expressing RC3 empty vector (VHL-) or wildtype VHL (VHL+) were kindly provided by Dr. Michael Ohh (University of Toronto). Whole-genome H3K27ac ChIP-seq was performed on these two isogenic cell lines.
Growth protocol 786-O cells were grown in RPMI-1640 medium (Sigma) supplemented with 10% fetal bovine serum (Gibco). Cells were maintained in a 5% CO2-humidified incubator at 37°C.
Extracted molecule genomic DNA
Extraction protocol One million cells were fixed in 1% formaldehyde/PBS buffer for 10 min at room temperature. Fixation was stopped by addition of glycine to a final concentration of 125 mM. Cells were washed 3 times with TBSE buffer. Pelleted cells were lysed in 100 µl 1% SDS lysis buffer and sonicated to 300-500bp using a Bioruptor (Diagenode). Sonicated DNA was normalized for each pair of cells with and without wildtype VHL before immuno-precipitation. The total volume of immunoprecipitation was 1 ml and the amount of antibody used was 2 µg. The input DNA was precleared with protein G Dynabeads (Life Technologies) for 1 hr at 4°C and then incubated with antibodies conjugated protein G beads overnight at 4°C. The beads were washed 3 times with cold wash buffer.
Whole-genome-amplification was performed on ChIP DNA and input using the WGA4 kit (Sigma-Aldrich). The amplified DNA was used with NEBNext ChIP-Seq library prep reagent set.
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina HiSeq 2500
 
Data processing Sequencing reads were trimmed (10bp from front and back) and mapped against human genome reference hg19 using the Burrows-Wheeler Aligner (BWA) (version 0.6.2) 'mem' algorithm. Only reads with mapQ >10 and with duplicate removed by rmdup were used in the subsequent analysis
H3K27ac and H3K4me1 ChIP-seq were called with CCAT whereas H3K27me3 ChIP-seq were called with MACS2
Genome_build: hg19
Supplementary_files_format_and_content: ChIP-seq peaks are in bed format, including 5 columns: "chromosome" "start of region" "end of region" "peak name" "peak enrichment"
