Expression of cytosolic glutathione S-transferase subtypes in human small airway epithelium and alveolar macrophages for the total study population. A. Relative average gene expression levels of GST isoenzymes in small airway epithelium of healthy nonsmokers (n = 35) and healthy smokers (n = 35). B. Relative average gene expression levels of GST isoenzymes in alveolar macrophages of healthy nonsmokers (n = 22) and healthy smokers (n = 34). For both panels, all cytosolic GSTs are shown on the ordinate and those GST subtypes whose probe sets were called as “Present” by Affymetrix “P” call in fewer than 50% of subjects are referred to as “not expressed” as indicated by an asterisk. GST subtypes known to be affected by common (>5% frequency) heritable copy number variation are highlighted by black bars. The Affymetrix HGU133 Plus 2.0 microarray has no specific probeset for GSTT2B, a duplicate gene of GSTT2, and therefore is not shown.
