(a) TF activity was measured in the indicated treatments. Data are presented as arbitrary units, which indicate fold-change above background TF levels and were generated from the mean of three separate experiments. (b) mRNA expressions of β-actin, IL-6, and TF are shown from HUVEC, HCAEC, and HMVEC incubated with IL-1β (1000 pg/mL) in the absence or presence of BTE (40 μg/mL) and RSV (40 μM). The treatments of cell cultures were background control (lane 1), IL-1β 1000 pg/mL (lane 2), IL-1β + BTE (lane 3), IL-1β + RSV (lane 4), BTE (lane 5), and RSV (lane 6). Results shown are from one representative experiment of two separate ones performed.
