Change in p300 association with the TM promoter following TNF-α stimulation. Chromatin immunoprecipitation was performed in HUVECs stimulated with or without 80 ng/mL human TNF-α for 1 hour using an antibody recognizing p300 and primers/probes specific for either the TM (left) or tissue factor (TF; right) promoters. Values are the mean ± SEM for 3 experiments. ^*P = .04 for AdIκBsr versus AdNull groups.
