چکیده

مقدمه و هدف: سولفورموستارد(SM)  یک ماده شیمیایی و سمی است که در بروز عوارض ریوی و فرآیندهای التهابی در افراد مواجهه یافته با این گاز نقش مهمی دارد. FOXP3 یک فاکتور رونویسی مهم در عملکرد سلول‌های Treg است. تغییر الگوی متیلاسیون FOXP3 تحت تأثیر مواد شیمیایی و سمی باعث بروز بیماری‌های ریوی مزمن می‌شود. هدف از این مطالعه بررسی اثر ماده‌‌ی شیمیایی و سمی SM بر وضعیت متیلاسیون پروموتر FOXP3 در جانبازان شیمیایی با عوارض تأخیری ریوی است.
 
مواد و روش‌ها: در این مطالعه، 20 نفر مواجهه یافته با گازخردل بعنوان گروه مورد و 20 نفر سالم بعنوان گروه کنترل می‌باشند. DNA از نمونه‌های خون استخراج گردید. وضعیت متیلاسیون پروموتر ژن‌ FOXP3 از طریق تست Methylation specific PCR(MSP) بررسی گردید.
 
نتایج: در متیلاسیون ژن FOXP3 بین دو گروه اختلاف معناداری وجود نداشت.
 
نتیجه‌گیری: وضعیت متیلاسیون ژن FOXP3 در گروه مواجهه یافته خفیف و متوسط تغییر معناداری پیدا نکرده است. به منظور یافتن نقش این ژن در پاتولوژی ریه مصدومین شیمیایی نیاز به سنجش سایر فاکتورهای اپی‌ژنتیکی و بررسی‌های بیشتر وجود دارد.

چکیده [English]

Background and Objective: Sulfur mustard (SM) is a toxic and chemical agent. The incidence of pulmonary complications and inflammatory processes play an important role in SM-exposed individuals. FOXP3 is one of the important factors in the development of chronic pulmonary diseases. FOXP3 gene promoter due to exposure to chemical and toxic materials leads to chronic pulmonary disease. In this study, the effect of toxic sulfur mustard was evaluated on the promoter methylation status of FOXP3 in SM-exposed individuals with delayed pulmonary complications.
 
Materials and Methods: In this case-control study, 20 SM exposed cases and 20 unexposed as control were studied. DNA was extracted from blood samples. Methylation specific PCR(MSP) was used to evaluate promoter methylation status of FOXP3.
 
Results: There was no significant difference between the promoter methylation status of FOXP3 in the exposed group as compared to control group.
 
Conclusion: The methylation status of the FOXP3 gene did not significantly change after exposure to sulfur mustard and other mechanisms might be involved in expressing this gene. To determine the effect of SM on methylation and its role in the pathogenesis of chemical victims’ lung complications, it is needed to measure other epigenetic factors and further studies.
