چکیده

مقدمه: Multiple sclerosis (MS) یک بیماری خود ایمنی مزمن سیستم‌ عصبی ‌مرکزی است که عوامل مختلف ژنتیک و محیطی در شیوع آن نقش دارند. با توجه به نقش استئوپونتین ‌(OPN یا Osteopontin) و گیرنده‌ی آن (ITGA4 یا Integrins alpha-4/beta-1) در پاسخ‌های ‌ایمنی، ژن‌های‌ کد کننده‌ی استئوپونتین‌ و ITGA4 می‌توانند‌‌‌ به عنوان عواملی جهت بررسی استعداد ابتلا به بیماری MS در نظر گرفته شوند. در مطالعه‌ی‌ حاضر، فراوانی پلی‌مورفیسم (rs28357094 T>G) در ژن OPN و پلی‌مورفیسم (rs1449263 A>G) در ژن ITGA4 در افراد مبتلا به MS در مقایسه با افراد سالم در جمعیت اصفهان مورد بررسی قرار گرفت.روش‌ها: از 100 بیمار مبتلا به MS در استان اصفهان به عنوان گروه مورد و 100 فرد سالم به عنوان گروه شاهد نمونه‌گیری خون انجام شد. ژنوتایپ‌های rs28357094 ژن OPN و rs1449263 ژن ITGA4 از DNA استخراج شد و با استفاده از تکنیک High resolution melt real time polymerase chain reaction (HRM real time PCR) مورد بررسی قرار گرفت. بررسی آماری با استفاده از نرم‌افزار SPSS انجام شد.یافته‌ها: در این مطالعه، فراوانی ‌ژنوتایپ TT (OPN-rs28357094) (020/0 = P، 85/1 = OR یا Odd ratio) و همچنین فراوانی ژنوتایپ AA (ITGA4-rs1449263) (012/0 = P، 10/2 = OR) در افراد مبتلا به MS به طور معنی‌داری بیشتر از افراد سالم بود.نتیجه‌گیری: پلی‌مورفیسم ژن OPN (rs28357094) و ژن ITGA4 (rs1449263) با استعداد ابتلا به بیماری MS در جمعیت اصفهان مرتبط است.

چکیده [English]

Background: Multiple sclerosis (MS) is a chronic autoimmune disease of the central nervous system (CNS). Various factors including genetic and environmental factors are involved in the prevalence of MS. The Osteopontin (OPN) and its receptor Integrins alpha-4/beta-1 (ITGA4) have important role in immune response, so their encoding gene could be considered as a candidate for susceptibility to MS diseases. In the present study, we evaluated the frequency of OPN (rs28357094T > G) and ITGA4 (rs1449263A>G) polymorphisms in MS patients compared with healthy controls in Isfahan, Iran population.Methods: Blood samples were collected from 100 patients with multiple sclerosis and 100 healthy controls. After DNA extraction, OPN (rs28357094) and ITGA4(rs1449263) polymorphisms were detected with high resolution melt real time polymerase chain reaction (HRM Real Time PCR) technique. The results were analyzed with the SPSS software.Findings: In this study, frequency of TT genotype (OPN-rs28357094) (P = 0.020, OR = 1.85) and AA genotype (ITGA4 - rs1449263) (P = 0.012, OR = 2.10) in Patients with multiple sclerosis were higher than the control group significantly.Conclusion: The results of this study show that rs28357094 T>G on OPN gene and ITGA4-rs1449263A > G polymorphisms were associated with susceptibility to multiple sclerosis in Isfahan population.
