Title |
THP1-LPS-1-BWA-SP1 |
Sample type |
SRA |
|
|
Source name |
THP-1
|
Organism |
Homo sapiens |
Characteristics |
cell line: THP-1 agent: LPS sample pair: 1 chip antibody: SP1
|
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

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.
