Одним из ключевых компонентов в развитии атеросклероза является нарушение липидного обмена. Однако роль эпигенетических механизмов в данном процессе изучена недостаточно. Цель. Характеристика вариабельности метилирования гена липазы PNPLA2 в клетках артерий различной локализации и лейкоцитах периферической крови при атеросклерозе. Материалы и методы. Оценка уровня метилирования ДНК в атеросклеротических бляшках коронарных и сонных артерий, а также стенке непораженных внутренних грудных артерий и лейкоцитах периферической крови выполнена методом бисульфитного пиросеквенирования. Статистический анализ полученных данных выполнен в программной среде R. Результаты и выводы. Для клеток артериальной стенки из области атеросклеротических бляшек коронарных артерий характерны более высокие уровни метилирования в промоторном регионе гена PNPLA2 по сравнению с непораженной стенкой внутренних грудных артерий. Уровень метилирования анализируемой области гена в лейкоцитах больных атеросклерозом ассоциирован с курением и приемом статинов.</p></abstract><trans-abstract xml:lang="en"><p>One of the key components in the development of atherosclerosis is the metabolic imbalance of lipids. However, the role of epigenetic mechanisms in this process is studied insufficiently. The aim of our study was to characterize variability of the PNPLA2 lipase gene methylation in the cells of differently localized arteries and peripheral blood leukocytes in atherosclerosis. Materials and methods. Using bisulfite pyrosequencing, we performed the assessment of DNA methylation level in atherosclerotic plaques of coronary and carotid arteries, and in the wall of unaffected internal thoracic arteries, and in peripheral blood leukocytes of patients with atherosclerosis. Statistical data analysis was performed in R software environment. Results and conclusions. Cells of coronary atherosclerotic plaques were found to have higher levels of methylation in the promoter of PNPLA2 gene compared to unaffected wall of internal thoracic arteries. Methylation level of analyzed gene region in leukocytes of patients with atherosclerosis was associated with smoking and statins.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>метилирование ДНК</kwd><kwd>липаза</kwd><kwd>атеросклероз</kwd><kwd>DNA methylation</kwd><kwd>lipase</kwd><kwd>atherosclerosis</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">Аронов ДМ, Лупанов ВП.
