Description
Summary:Certain transient receptor potential (TRP) channels including and are widely expressed in the respiratory tract and have been shown to be the receptors of cigarette smoke and particulate matter-the main causative factors of chronic obstructive pulmonary disease (COPD). The aim of the study was to investigate the effect of and polymorphisms on COPD predisposition and lung function in COPD patients. The study enrolled 143 COPD patients and 104 smokers with post-bronchodilator forced expiratory volume in one second (FEV1)/forced vital capacity (FVC) > 70%. Lung function was measured by spirometry. and polymorphisms were genotyped by LATE-PCR. None of the polymorphisms significantly influenced COPD predisposition after correction for covariates and multiple testing. Among COPD patients, the TT genotype of rs7819749 was significantly associated with higher degree of bronchial obstruction. In addition, we established that carriers of the C allele of rs11562975 more commonly had post-bronchodilator FEV1 < 60% (OR 3.2, 95%CI (1.14-8.94), = 0.03) and revealed the effect of rs959976 and rs17865682 on bronchodilator response in COPD. Thus, the obtained results suggest possible involvement of and in COPD pathogenesis, indicating the necessity to further investigate their functional role in this pathology.
