Исследовать взаимосвязь между экспрессией Са2+-транспортирующих белков саркоплазматического ретикулума, полиморфными вариантами их генов и структурно-функциональным состоянием сердца пациентов с фибрилляцией предсердий (ФП).</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследование включили пациентов с ФП. Больным проведена радиочастотная аблация, во время которой была взята биопсия миокарда. Пациентам проводили эхокардиографию (ЭхоКГ) до оперативного вмешательства. У больных определены полиморфные варианты rs1860561 гена ATP2A2 и rs6684209, rs7521023 гена CASQ2 методом полимеразной цепной реакции в режиме реального времени и уровень экспрессии белков SERCA2a и CASQ2 в миокарде методом иммуноблоттинга.</p></sec><sec><title>Результаты</title><p>Результаты. Для носителей генотипов GG rs1860561 гена ATP2A2 и CC rs6684209 гена CASQ2 характерны значимо более высокие экспрессии соответствующих белков. С помощью кластерного анализа были выявлены группы пациентов по уровню экспрессии SERCА2a и CASQ2: 1 – пациенты с низким содержанием белков; 2 – с высоким содержанием белков. По клинико-анамнестическим показателям пациенты отобранных групп оказались практически однородны. У пациентов с высоким уровнем SERCА2a величины конечного систолического и диастолического объемов левого желудочка (ЛЖ) были значимо больше, чем таковые у больных с низким уровнем этого белка. Скорости раннего (пик Е) и позднего диастолического наполнения (пик А) ЛЖ были статистически значимо ниже в группе с высоким уровнем экспрессии SERCА2a. Сравнительный анализ данных ЭхоКГ пациентов, распределенных по уровню экспрессии CASQ2 в миокарде, не выявил значимых различий между группами.</p></sec><sec><title>Заключение</title><p>Заключение. Генотипы rs1860561 гена ATP2A2 и rs6684209 гена CASQ2 могут модулировать уровень экспрессии SERCA2a и CASQ2. Экспрессия SERCA2a сопряжена с функционально-структурными показателями сердца пациентов с ФП.</p></sec><sec><title> </title><p> </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To investigate the relationship between the expression of Ca2+ handling proteins of the sarcoplasmic reticulum, polymorphic variants of their genes, and structural and functional parameters of the heart in patients with atrial fibrillation (AF).</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study included patients with AF. The patients underwent radiofrequency ablation, during which a myocardial biopsy was taken. The patients underwent echocardiography (EchoCG) before surgery. Polymorphic variants rs1860561 of the ATP2A2 gene and rs6684209 and rs7521023 of the CASQ2 gene were determined in the patients by real-time polymerase chain reaction (PCR), and the level of expression of SERCA2a and CASQ2 proteins in the myocardium was detected by immunoblotting.</p></sec><sec><title>Results</title><p>Results. Carriers of the GG genotype at rs1860561 of the ATP2A2 gene and CC genotype at rs6684209 of the CASQ2 gene were characterized by significantly higher expression of the corresponding proteins. Using cluster analysis, we identified groups of patients by the level of SERCA2a and CASQ2 expression: group 1 – patients with low protein content; group 2 – patients with high protein content. According to clinical and anamnestic parameters, the patients in the selected groups were homogeneous. In patients with high SERCA2a levels, the end systolic and diastolic volumes of the left ventricle (LV) were significantly higher than those in patients with low levels of this protein. The rates of early (peak E) and late left ventricular diastolic filling (peak A) were significantly lower in the group with high SERCA2a expression. A comparative analysis of EchoCG data of patients distributed by the level of CASQ2 expression in the myocardium did not reveal significant differences between the groups.</p></sec><sec><title>Conclusion</title><p>Conclusion. The polymorphic variant rs1860561 of the ATP2A2 gene and rs6684209 of the CASQ2 gene can modulate the level of SERCA2a and CASQ2 expression. SERCA2a expression is associated with the functional and structural parameters of the heart in patients with AF.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>фибрилляция предсердий</kwd><kwd>Са2+-АТФаза саркоплазматического ретикулума</kwd><kwd>кальсеквестрин</kwd><kwd>полиморфные варианты генов</kwd><kwd>эхокардиография</kwd></kwd-group><kwd-group xml:lang="en"><kwd>atrial fibrillation</kwd><kwd>Ca2+-ATPase of the sarcoplasmic reticulum</kwd><kwd>calsequestrin</kwd><kwd>polymorphic variants of genes</kwd><kwd>echocardiography</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках темы фундаментальных научных исследований по государственному заданию № АААА-А15-115123110026-3 (исследование полиморфизмов генов ATP2A2 и CASQ2) и гранта РНФ 20-75-00003 (изучение белков SERCA2a и CASQ2)</funding-statement><funding-statement xml:lang="en">The work was carried out within the basic research theme under the state assignment No. AAAA-A15-115123110026-3 (study of polymorphisms of the ATP2A2 and CASQ2 genes) and RNF 20-75- 00003 grant (study of the SERCA2a and CASQ2 proteins)</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">Alonso A., Bengtson L.G.
