Fig. 5From: Long-term treatment of clarithromycin at a low concentration improves hydrogen peroxide-induced oxidant/antioxidant imbalance in human small airway epithelial cells by increasing Nrf2 mRNA expressionEffects of CAM on Nrf2 mRNA expression in SAECs stimulated with H2O2. Nrf2 mRNA was measured using real-time RT-PCR. Samples were obtained from cell pellets of control cells, of cells stimulated with 100 μM H2O2 alone, or of cells pretreated with 1 μM, 5 μM or 10 μM CAM for 72 h before stimulation with 100 μM H2O2 for 1 h. Data are presented as means ± SD of four independent experiments. **p < 0.01 vs. control cells, ## p < 0.01 vs. cells stimulated with H2O2 alone, †† p < 0.01 vs. cells pretreated with 10 μM CAMBack to article page
