Inhibitory effect of SAA1 siRNA on the levels of O2− production (a), NADPH oxidase activity (b) and NOX-4 protein (c-d) in LPS (1 μg/ml) -induced VSMCs via suppressing NOX4/ROS pathway (n = 3). Notes: The same letters represented no significant differences, P > 0.05; and different letters indicated significant differences, P < 0.05
