From: Smoking-mediated up-regulation of GAD67 expression in the human airway epithelium
Immunohistochemistry assessment of GAD67 expression in large airway epithelium in healthy nonsmokers and healthy smokers, representing the broad range of up-regulation of the GAD67 gene. Panels A, C, E, G, I, K, stained with anti-GAD67 antibody. Panels B, D, F, H, J, L, stained with mouse IgG control. A. Healthy nonsmoker, anti-GAD67; B. Healthy nonsmoker, IgG; C. Healthy smoker, anti-GAD67; D. Healthy smoker, IgG; E. Healthy nonsmoker, anti-GAD67; F. Healthy nonsmoker, IgG; G. Healthy smoker, anti-GAD67; H. Healthy smoker, IgG; I. Healthy smoker, anti-GAD67; J. Healthy smoker, IgG; K. Healthy smoker, anti-GAD67; and L. Healthy smoker, IgG l. Bar = 10 μm.
