Fig. 7From: Resveratrol prevents nanoparticles-induced inflammation and oxidative stress via downregulation of PKC-α and NADPH oxidase in lung epithelial A549 cellsEffects of resveratrol on iNOS expression (a), NO production (b), COX-2 expression (c), and PGE2 production (d) in CBNPs-treated A549 cells. Cells were pre-treated with resveratrol for 1 h before addition of CBNPs (25 μg/mL) for 24 h. Bars represent the mean ± S.E.M. from six independent experiments. ###P < 0.001 vs. control group (without any treatment). *P < 0.05, **P < 0.01, ***P < 0.001 vs. CBNPs (25 μg/mL) groupBack to article page
