LPS treatment increases ROS generation in SW982 cells. a DHE staining (red fluorescence) was performed to evaluate the ROS levels. Representative images are shown from repeated experiments. Scale bar = 100 μm. b Flow cytometric analysis of the generation of ROS in cells treated with different concentrations of LPS for 24 h. c Relative levels of ROS (n = 3, **P < 0.01 vs CTL)
