Sample GSM1192072 Query DataSets for GSM1192072
Status Public on Jun 09, 2014
Title IgG.shRECQL5-5
Sample type SRA
 
Source name HEK293 cells, IgG.shRECQL5-5
Organism Homo sapiens
Characteristics cell line: HEK293
chip antibody: Non-specific IgG control
treatment: RECQL5 shRNA 5
Growth protocol HEK293 cells were infected with lentiviral supernatant carrying shRNA specific for RECQL5 or CTRL shRNA. Once KD efficiency was assessed by Western Blot, cells were processed for RNA Pol II. ChIP-Seq. HEK293T-rex cells were transfected with the pcDNA4/TO-RECQL5 plasmid, carrying a full length version of RCQL5 under a Doxycycline inducible promoter. Once the doses of Doxycycline for the overexpression where assessed by Western Blot the samples were processed for RNA Pol II ChIP-Seq.
Extracted molecule genomic DNA
Extraction protocol Cells were cross-linked with formaldehyde 1% final. Nuclei were extracted in low salt conditions and burst in high salt before shearing the DNA to reduce the size to 300-400 bp and performing ChIP with an RNA Pol II specific antibody.
DNA libraries were prepared according to Illumina's instructions and run on a GAIIX sequencer
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina Genome Analyzer IIx
 
Description Control used in peak calling
Processed data file: RNAPolII.shRECQL5-5_peaks.txt
Data processing Basecalls performed using CASAVA version 1.8
ChIP-seq reads were aligned to the hg19 genome assembly using Bowtie 0.12.7 with default parameters appart from the “--best” option.
BAM files representing the same sample were merged and reads mapping to regions blacklisted for mappability by the Encode project were removed.
Peaks were called against an IgG control using MACS v1.4.2 with the following settings: --gsize (hs), --tsize (36), --mfold (8,30), --pvalue (0.00001)
Genome_build: hg19
Supplementary_files_format_and_content: Tab delimited text files detailing the peaks called by MACS (see supplementary files linked to Series record)
