Effects of recombinant SAA1 protein treatment for different time points on NOX4/ROS pathway in LPS-induced VSMCs (n = 3). Notes: The levels of O2 production (a), NADPH oxidase activity (b) and NOX-4 protein (c-d) in VSMC after pre-incubation with 20 μg/ml SAA1 for different time points (0, 24, 48, 72 h) followed by the addition with 1 μg/ml LPS for 24 h. The same letters represented no significant differences, P > 0.05; and different letters indicated significant differences, P < 0.05
