Окислительный стресс является ведущим механизмом повреждения головного мозга при ишемии и последующей реперфузии. Тиоредоксиновая система является наиболее важным антиоксидантным барьером клетки, способным регулировать ее окислительно-восстановительный статус. Целью исследования было изучение ассоциации однонуклеотидного полиморфизма rs1128446 гена эндогенного регулятора тиоредоксина ТXNRD1 с риском развития МИ. Материалом для исследования послужила выборка неродственных жителей Центральной России общей численностью 825 человек. В исследование были включены 375 пациентов с МИ (216 мужчин, 159 женщин; средний возраст 59,44±0,51 лет). Контрольную группу составили 450 относительно здоровых индивидуумов (249 мужчин, 201 женщина, средний возраст 61,69±0,38 лет) без кардио- и цереброваскулярных заболеваний в анамнезе и имеющих нормальный уровень артериального давления. Генотипирование SNP проводили методом ПЦР в режиме реального времени путем дискриминации аллелей с помощью TaqMan-зондов. Для анализа ассоциаций генотипов с развитием заболевания пользовались лог-аддитивной регрессионной моделью. Все расчеты выполнены относительно минорного аллеля; введены поправки на пол и возраст. SNP rs1128446 ТXNRD1 был связан с повышенным риском развития МИ (OR=1,89; 95% CI=1,48-2,43; p&lt;0,0001). Проведенный биоинформатический анализ выявил высокий регуляторный потенциал данного SNP в тканях сердечно-сосудистой системы. Таким образом, впервые установлена ассоциация rs1128446 ТXNRD1 с развитием МИ.</p></abstract><trans-abstract xml:lang="en"><p>Cerebral stroke (CS) is the leading factor in cognitive decline and dementia and ranks third in the structure of mortality worldwide. Oxidative stress is the basic mechanism of brain damage after cerebral ischemia-reperfusion. The thioredoxin system is the most important antioxidant barrier of the cell, capable of regulating its redox status. The aim of this study was to investigate the association of the common single nucleotide polymorphism rs1128446 in gene encoding the endogenous thioredoxin regulator TXNRD1 with the risk of CS. A total of 825 unrelated individuals from Central Russia were included for this study: 375 patients with CS (216 males, 159 females; 59.44±0.51 years old) and 450 healthy controls (249 males, 201 females, 61.69±0.38 years old). Genotyping was performed using TaqMan-based PCR. To analyze the associations of genotypes with the risk of diseases, a log-additive regression model was used. All calculations were performed relative to the minor allele; corrections for gender and age have been introduced. SNP rs1128446 TXNRD1 was associated with an increased risk of CS (OR=1.89; 95% CI=1.48-2.43; P&lt;0.0001). Bioinformatic analysis revealed a high regulatory potential of this SNP in tissues of the cardiovascular system. Thus, for the first time, the association of rs1128446 TXNRD1 with the development of CS was revealed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>мозговой инсульт</kwd><kwd>окислительный стресс</kwd><kwd>тиоредоксин</kwd><kwd>rs1128446</kwd><kwd>ТXNRD1</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cerebral stroke</kwd><kwd>oxidative stress</kwd><kwd>thioredoxin</kwd><kwd>rs1128446</kwd><kwd>ТXNRD1</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Mendis S., Davis S., Norrving B.
