Fluorescence value of ROS in the presence of Cu2+. Samples were treated using DCFH-DA probe and the intracellular ROS production was qualified. The fluorescence value in Cu2+-treated cells was compared to that in the control cells at each time point. Data are the means for three independent experiments and are presented as the means ± SD. **, P < 0.01
