Mean RNA expression levels for pirin in smokers and non-smokers A. Microarray relative expression values (non-smokers n = 9, smokers n = 13, right and left lung samples for each individual). The relative expression level for pirin represents the normalized expression level in each array divided by the median expression level for pirin in all 44 microarrays. B. Comparison of microarray and TaqMan relative expression values (nonsmokers n = 3, smokers n = 9). Shown are the mean expression level of pirin ± standard error in airway epithelium of nonsmokers and smokers quantified by either microarray (p < 0.01) and TaqMan (p < 0.01).
