Correlation of small airway epithelium gene expression levels with GSTM1 CNV genotype. A. Microarray. GSTM1 CNV genotype is plotted against normalized average gene expression level for the two indicated Affymetrix GSTM1 expression probe sets (healthy nonsmokers, n=22; healthy smokers, n=34). P values represent Kruskal Wallis tests. B. TaqMan RT-PCR. The normalized average expression level by TaqMan RT-PCR is shown on the ordinate for incremental GSTM1 copy number, for a random subset of individuals (n = 22). P value shown is a Kruskal-Wallis test. C. Comparisons of GSTM1 CNV genotypes vs SAE gene expression levels. The three plots show GSTM1 copy number on the abscissa versus normalized relative gene expression levels on the ordinate, for GNAI3, GSTM1 and GSTM3 respectively, in the total study population (n = 70). Kendall tau rank correlation p values are as shown. For A and B the error bars represent the standard error.
