TNF alpha is one of the inflammatory mediator and induce genes mainly by transcriptional factor, p65, in endothelial cells. This time, we performed a time course study to detect the change of localization of p65 and Pol II.Overall design: To identify p65 and Pol II binding sites, we used chromatin immunoprecipitation with deep sequencing (ChIP-seq) of HUVECs treated with or without TNF alpha for 30 mins. Cells were starved before stimulation longer than 16 hours. HUVECs were used within the first 6 passages. For crosslinking, 10 mM of EGS in 50% glacial acetic acid was used for 45 min, followed by 20 min of 1% paraformaldehyde treatmet was used. |
