Одним из известных механизмов развития и прогрессирования сахарного диабета 2 типа (СД2) является окислительный стресс. Как фермент метаболизма глутатиона, аминопептидаза ANPEP играет важную роль в антиоксидантной системе организма.Цель: изучение вклада полиморфизмов гена ANPEP и средовых факторов риска в формирование предрасположенности к заболеванию.Методы. Материалами исследования послужили образцы геномной ДНК, полученные от 1579 больных СД2 и 1627 здоровых добровольцев. Генотипирование выполнено методами MALDI-TOF масс-спектрометрии (MassArray Analyzer 4, Agena Bioscience) и ПЦР в реальном времени (CFX 1000, Bio-Rad). Статистическую обработку полученных данных проводили с помощью программ SNPStats, PLINK, MBMDR.Результаты. Установлен протективный эффект сочетания носительства полиморфизмов rs12148357, rs25653 и rs11073891 гена ANPEP и отсутствия курения и психо-эмоционального стресса, потребления нормального количества жиров, углеводов, клетчатки и свежей растительной пищи. В то же время rs9920421 и rs7111 ассоциированы с повышенным риском развития СД2 только в комбинации с высококалорийным питанием и дефицитом белка в пище. Установлено 5165 значимых двухлокусных моделей генно-средовых взаимодействий, ассоциированных с риском развития СД2 (84,8% моделей составили SNPs и 15,2% – факторы среды).Выводы. Средовые факторы модулируют риск развития СД2 у носителей полиморфизмов гена ANPEP. При этом полиморфные варианты ANPEP и других генов регуляции редокс-гомеостаза тесно взаимодействуют с генами-кандидатами СД2 и средовыми факторами в детерминации риска развития СД2.</p></abstract><trans-abstract xml:lang="en"><p>Background. One of the known mechanisms of development and progression of type 2 diabetes mellitus (T2D) is oxidative stress. As an enzyme of glutathione metabolism, aminopeptidase ANPEP plays an important role in the body’s antioxidant system.Aim: to analyze the contribution of polymorphisms of the ANPEP gene and environmental risk factors to the formation of predisposition to T2D.Methods. The study included genomic DNA samples obtained from 1579 T2D patients and 1627 healthy volunteers. Genotyping was performed using MALDI-TOF mass spectrometry (MassARRAY Analyzer 4, Agena Bioscience) and real-time PCR (CFX 1000, Bio-Rad). Statistical processing of the obtained data was carried out using the online programs SNPStats, PLINK, MBMDR.Results. A protective effect of the combination of carriage of the rs12148357, rs25653 and rs11073891 polymorphisms of the ANPEP gene and the absence of smoking and psycho-emotional stress, consumption of normal amounts of fats, carbohydrates, fiber and fresh plant foods was established. At the same time, rs9920421 and rs7111 are associated with an increased risk of developing T2D only in combination with a high-calorie diet and protein deficiency in food. A total of 5165 significant two-locus models of gene-environment interactions associated with the risk of developing T2D were identified (84.8% of the models were SNPs and 15.2% were environmental factors).Conclusion. Environmental factors modulate the risk of developing T2D in carriers of ANPEP gene polymorphisms. At the same time, polymorphic variants of ANPEP and other genes regulating redox homeostasis closely interact with T2D candidate genes and environmental factors in determining the risk of developing T2D.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сахарный диабет 2 типа</kwd><kwd>аминопептидаза ANPEP</kwd><kwd>однонуклеотидный полиморфизм</kwd><kwd>наследственная предрасположенность</kwd><kwd>средовые факторы</kwd><kwd>оксидантный стресс</kwd></kwd-group><kwd-group xml:lang="en"><kwd>type 2 diabetes mellitus</kwd><kwd>aminopeptidase ANPEP</kwd><kwd>single nucleotide polymorphism</kwd><kwd>hereditary predisposition</kwd><kwd>environmental factors</kwd><kwd>oxidative stress</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке гранта РНФ (проект № 20-15-00227).</funding-statement><funding-statement xml:lang="en">The study was carried out with financial support of Russian Science Foundation grant (project No. 20-15-00227).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">DeFronzo R.A., Ferrannini E., Groop L. et al.
