From: Disparate oxidant gene expression of airway epithelium compared to alveolar macrophages in smokers
Expression of oxidant-related genes in small airway epithelium and alveolar macrophages of healthy nonsmokers and healthy smokers. A. Expression of oxidant-related genes in healthy nonsmokers. The % of all oxidant-related genes (total of 155 genes surveyed) that were expressed (defined as Affymetrix detection call of "present" in >50% of nonsmoker individuals, n = 19) is presented on the ordinate and the categories in which these genes are expressed are presented on the abscissa. Each bar represents the % of genes expressed and inside each bar is the corresponding number of oxidant-related genes expressed. B. Expression of oxidant-related genes in healthy smokers. The % of all oxidant-related genes that were expressed in healthy smokers (n = 30) is presented on the ordinate and the categories in which these genes are expressed is presented on the abscissa. Each bar represents the % of genes expressed and inside each bar is the corresponding number of oxidant-related genes expressed.
