(A) HUVECs were treated with EtOH or increasing concentrations of resveratrol. (B) Where indicated, HUVECs were pretreated with 100 nM ICI 182,780 for 6 h; 50 nM Wortmannin (Wort), 50 mM PD98059 (PD), or 50 nM pertussis toxin (PTX); or 10 μg/ml DEPE L59, L75, S50, or S80 for 1 h followed by the addition of 10 nM resveratrol for 4 h. Total mRNA was isolated following treatment and QRT-PCR was performed as described in Material and Methods. Values are the average of 3 separate experiments ± SEM. * p < 0.05 versus EtOH; ** p < 0.05 versus resveratrol.
