Figure 2From: Smoking-mediated up-regulation of GAD67 expression in the human airway epithelium GABAergic system gene expression in large and small airway epithelium. A. Microarray present call analysis of GABAergic system genes in large airway epithelium. B. Microarray present call analysis of GABAergic system genes in small airway epithelium. For A and B, the dashed line represents P call of 20%. C. RT-PCR assessment of GABAergic system gene expression in large and small airway epithelium. Human brain RNA was used as a positive control. Shown are representative RT-PCR results of 1 large airway epithelium sample and 1 small airway epithelium sample.Back to article page
