Sample GSM2293340 Query DataSets for GSM2293340
Status Public on Aug 22, 2017
Title A-498 Input
Sample type SRA
 
Source name ccRCC cell line
Organism Homo sapiens
Characteristics histone: Input
chip antibody: none
source: A498 (ATCC HTB-44)
Growth protocol All ccRCC cells (786-O, A498 and tumor-derived cell lines) were grown in RPMI-1640 medium (Sigma) supplemented with 10% fetal bovine serum (Gibco). HK-2 and PCS400 were grown in Renal Epithelial Cell Basal Medium (ATCC). Cells were maintained in a 5% CO2-humidified incubator at 37°C. In order to derive cell lines from primary tumors, ccRCC primary tumor tissues were disassociated by collagenase. Dissociated cells were maintained in RPMI with 10% FBS. At 80-90% confluency, the cells were passaged at 1:3 ratio. The cultured cells were considered to be successfully immortalized after 60 passages.
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). 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.

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
Significant peaks were called using CCAT (p-value < 0.05).
Genome_build: hg19
Supplementary_files_format_and_content: bed format for ucsc genome browser, including 5 columns: "chromosome" "start of region" "end of region" "peak name" "fold change"
