Comparison of the fold-changes of smoking responsive oxidant-related genes in the small airway epithelium and alveolar macrophages in the different oxidant-related gene categories. A. Fold-change of smoking responsive oxidant-related genes in small airway epithelium. B. Fold-change of smoking responsive oxidant-related genes in alveolar macrophages. For both A and B, the fold-change is presented on the ordinate and the oxidant-related genes in their categories on the abscissa. Each bar represents the fold-change (average expression in healthy smokers compared to average expression in healthy nonsmokers) of an oxidant related gene in the corresponding category and error bars represent the standard error for the ratio.
