Examples of genes up- and down-regulated by smoking with high coefficient of variation in normal smokers and smokers with COPD. The normalized expression levels for the non-smokers, normal smokers and smokers with COPD were compared. A. G6PD - Glucose-6-phosphate dehydrogenase; B. AKR1B10 - aldo-keto reductase family 1, member B10; C. GPX2 - glutathione peroxidase 2; D. HES6 - hairy and enhancer of split 6; E. DUSP5 - dual specificity phosphatase 5; and F. WNK4 - WNK lysine deficient protein kinase 4. The coefficient of variation for the genes in each of the study groups in shown in parentheses below the scatter plot; p values are based on unpaired t tests.
