Effects of Ac-SDKP in radiation-induced intracellular ROS generation in endothelial cells: Luciferase light signal as a measure of reactive oxygen species (ROS) activity examined by ROS-Glo™ H₂O₂ Assay. Average luminescence signal from the ROS-Glo™ Assay was compared with baseline control and treated cells. When compared to baseline control, radiation exposure significantly increased ROS generation in endothelial cells, which was inhibited by Ac-SDKP treatment group. N = 7 each group, *, p < 0.001 rad vs. control, †, p = 0.01 rad vs. rad + Ac-SDKP. Rad, radiation
