چکیده

سابقه و هدف: مطالعات نشان می‌دهند که ژن مبدل سیگنال و فعال کننده رونویسی (STATs) نقش مهمی را در ایجاد پلاک‌های آترواسکلروز و در نتیجه بروز انفارکتوس میوکارد (myocardial infarction (MI)) ایفا می‌کند. مطالعه حاضر با هدف تعیین رابطه میان پلی مورفیسم ژن STAT4 در موقعیت (rs3024839) با خطر ابتلا به سکته قلبی در جمعیت ایرانی انجام گردید.
موارد و روش‌ها: مطالعه حاضر به صورت مورد- شاهدی انجام شد. رابطه احتمالی بین پلی مورفیسم STAT4و ابتلا به MI بر روی یک گروه 200 نفره شامل بیماران مبتلا به سکته قلبی و 200 فرد سالم به عنوان کنترل بررسی گردید. دو گروه از لحاظ سنی و جنس همسان سازی شدند. پس از استخراج DNA و تکثیر، فراوانی ژنوتیپی و آللی با استفاده از واکنش زنجیره‌ای پلیمراز (PCR-ARMS)، در دو گروه مورد مطالعه تعیین گردید. نتایج با استفاده از نرم افزار SPSS و با تست‌های آماری مربع کای و رگراسیون لجستیک مورد ارزیابی قرار گرفت.
یافته‌ها: یافته‌ها حاکی از اختلاف معنی‌دار در فراوانی ژنوتایپ TC در ژن STAT4 بین دو گروه MI و کنترل بود ( 03/0=P). هیچ اختلاف معنی‌داری بین پلی مورفیسم ژن STAT4 و فاکتورهای خطر MI از جمله جنسیت، فشار خون، چربی خون، دیابت و نوع سکته قلبی (STEMI و NSTEMI) مشاهده نشد (05/0<P).
نتیجه گیری: به نظر می‌رسد احتمالاً پلی مورفیسم rs3024839 T/C ژن STAT4 نقش مهمی را در بروز MI ایفا ‌کند. اما با این وجود، مطالعات بیشتر با اندازه نمونه بیشتر برای تائید نتایج مطالعه حاضر ضرروری می‌باشد.

چکیده [English]

Background: The studies have demonstrated that Signal transduction and activation of transcription (STATs) play a major role in atherosclerotic plaque disruption and lead to myocardial infarction (MI). The present study was done to investigate the association between the STAT4 gene polymorphism in site of rs3024839 with the risk of developing MI in an Iranian population.
Material and Methods: This is a case-control study. The possible association between STAT4 polymorphism (SLC6A4) with the development of MI was investigate in a group of 200 patients with a history of MI and 200 healthy controls. The two groups were matched in terms of TCe and sex. After DNA extraction and replication, Genotypes and alleles frequency were determined in two groups using polymerase chain reaction (PCR-ARMS). The results were analyzed by SPSS software using Chi-square and logistic regression tests.
Finding: The result showed a significant difference in the rates of TC STAT4 genotype between MI and control groups (p=0.03). There was not any significant relationship between STAT4 gene polymorphisms and risk factor of MI such as sex, hypertension, dyslipidemia, diabetes, type of MI (STEMI or NSTEMI) (P>0.05).
Conclusion: The results of presented study reveal that the rs3024839 T/C polymorphism of the STAT4 gene probably plays a specific role in the risk of developing MI in Iranian population. But, further well-designed studies with large sample sizes are required to confirm our results.
