Abstract

Abstract
Introduction: Chronic Obstructive Pulmonary Disease (COPD) is a common multifactorial disease which has heterogeneous pathogenesis. The most important risk factor is smoking. In addition to many pathogenic mechanisms taking part in inflammatory process, Our study group does research on the relation of COPD with single nucleotide gene polymorphism at ET-1 gene. In the current studies there being a high ratio of Endotelin-1 (ET-1) in BAL liquid of COPD cases made researchers think ET-1 may have an important role in pathogenesis of COPD.
Methods: This prospective case-control study included 89 patients admitted with COPD and 87 control patients. In our study, we search for the density of single nucleotide gene polymorphism (+134 insA/delA) in ET-1 gene in the 87 smoking COPD and 89 healthy cases. Allele ratio and genotype distribution, distribution amongst three genotype in the COPD patient and healthy control group was analyzed. In this study, for endothelin gene -3A/-4A (-138 insertion/deletion) polymorphism analysis, PCR-RFLP method was used.
Results: In comparison with the healthy group, the COPD group has higher ratio of ET-1 gene (+134 insA/delA) polymorphism (p< 0,001).
Conclusion: Endotelin-1 gene polymorphism (+134 insA/delA) significantly increased in the patients than healthy ones (p<0,013). Endothelin-1 gene polymorphism may be considered as a predictive genetic factor of COPD in Türkiye.
