Free radical scavengers inhibit radiation-induced apoptosis and ceramide generation in bovine aortic endothelial cells (BAECs). Tempol or NAC was added to BAECs 10 min prior to 5 Gy irradiation (5 mM and 50 mM, respectively). Panel A: Apoptosis was scored 8 h after irradiation using the bis-Benzamide trihydrochloride staining. Panel B: Ceramide levels were measured using the diacylglycerol kinase assay 15 min after 5 Gy irradiation. Data are expressed as mean ± SD from three independent experiments.
