چکیده
Background:Nitric Oxide (NO) a potent vasodilator plays a pivotal role in blood pressure regulation. Evidences suggested that eNOS gene polymorphisms are associated with essential hypertension (EHT). We examined the potential association of 4a/4b, A922G, G894T, T786C eNOS gene polymorphisms with EHT in the southern population of Iran.Methods: 200 Iranian patients with EHT and 200 normotensive subjects were included. After collecting demographic data, polymerase chain reaction was used to determine genotype of 4a/4b polymorphism, and three other polymorphisms were analyzed by restriction fragment length polymorphism- polymerase chain reaction method (PCR-RFLP). Pairwise, ternary, and foursome haplotype analysis conducted to reveal their association with ETH. Association was determined by logistic regression analysis.Results: our results demonstrated statistically significant associations between T786C, G894T, and 4a/4a and the disease (P < 0.001) with an increased risk of hypertension (OR = 2, OR = 3.8, OR = 1.6, respectively), however, A922G variant had no significant association. 786C/922A, 786C/922G, 786C/4a, 786C/894T, 922A/4a, and 922G/4a haplotypes were associated an increased risk of hypertension, while 786T/922A, 786T/922G, 786T/894T, and 922A/4b were reversely associated (P < 0.001). Moreover, Ternary haplotype analysis revealed that 786C/922A/4a, 786C/922A/4b, and 786C/922G/4b haplotypes are significantly associated with hypertension while 786T/922G/4a and 786T/922G/894T haplotypes demonstrate protective effects against hypertension (P < 0.001).Conclusion: The 4b/4a and 786T/C polymorphisms emerged as the determinants modifying the risk of hypertension. The 786T/C, 4b/4a and 894G/T polymorphisms, individually and as haplotypes, associated significantly with risk of hypertension. The susceptible haplotypes were associated with an increased risk of hypertension.کلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
