A. Western blotting for GSTO1-1 in induced sputum of non-smokers, smokers and COPD-patients showed an decreased immunoreacitivity in patients with COPD compared to non-smokers (p = 0.023). B. GSTO1-1 could be detected in the plasma samples and bronchoalveolar lavage fluid. Representative Western blots from three non-smokers are shown. C. GSTO1-1 was also expressed in the culture medium of U937 monocytes and BEAS-2B cells. D. Lung tissue homogenates showed higher level of GSTO1-1 in the specimens obtained from non-smokers or smokers with normal lung function when compared to COPD, p = 0.003.
