Sample GSM800787 Query DataSets for GSM800787
Status Public on Mar 07, 2012
Title THP-1-LPS-1
Sample type SRA
 
Source name THP-1
Organism Homo sapiens
Characteristics cell line: THP-1
agent: LPS
sample pair: 1
chip antibody: H3K9/K14Ac
antibody vendor: Upstate, Charlottesville, VA, USA
antibody catalog number: 06-599
antibody lot number: DAM1422332
Treatment protocol THP-1 macrophages were then either left unstimulated (control) or stimulated with 1ug/ml LPS (LPS-stimulated) from Escherichia coli O55:B5 for 2 hours (Sigma Chemical Co., St. Louis, MO, USA) to induce an acute inflammatory response. To confirm an induction of the inflammatory response in the THP-1 macrophages, TNF mRNA levels were measured in control and LPS-stimulated samples.
Growth protocol THP-1 cells (monocyte cell line) (ATCC , Manassas, VA, USA) were maintained in culture in RPMI 1640 medium containing 10% fetal bovine serum, 1mM sodium pyruvate , 100 units/ml penicillin and 100 μg/ml streptomycin at 37°C with 5% CO2. For differentiation of THP-1 cells into macrophages a protocol using conditioned media as previously described by Whatling et al was used. To confirm differentiation of THP-1 monocytes into macrophages CD11b expression was measured using FACS and quantitative polymerase chain reaction (qPCR).
Extracted molecule genomic DNA
Extraction protocol DNA-protein complexes were eluted, treated with RNaseA (USB,Cleveland, OH, USA) for 4-6 hours at 45°C and Proteinase K (USB, Cleveland, OH, USA) overnight at 65°C. DNA was extracted by phenol/chloroform/isoamyl alcohol extraction, purified and resuspended in water. library construction: Illumina core center, standard protocol
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina Genome Analyzer
 
Data processing Sequence reads were 35 bases or longer but truncated to 35 bases to ensure base quality over the entire read. Reads were aligned to the human reference genome (GRCh37/hg19) with Burrows-Wheeler Alignment tool (BWA) (Li H and Durbinv R (2009) Fast and accurate short read alignment with Burrows-Wheeler transform. Bioinformatics 25 (14): 1754-60), and only uniquely mapped reads with a maximum of 2 mismatched bases were considered for further analysis. The sequence tag density generated from the input library (total DNA) was used as background.
