Поэтому цель данной работы — оценить значение изменений экспрессии микроРНК‑21 в ткани миокарда в развитии ремоделирования сердца при хроническом сокращении массы действующих нефронов в эксперименте. Материалы и методы. Крысы стока Wistar были разделены на две группы. В первую (контроль) вошло девять ложнооперированных животных. Во вторую (n = 9) — крысы с поэтапной резекцией 5/6 почечной ткани. Через 4 месяца после операции было измерено артериальное давление (АД), выполнено эхокардиографическое (ЭхоКГ) исследование сердца и определен уровень относительной экспрессии микроРНК‑21 в ткани миокарда. Результаты. У крыс с экспериментальным уменьшением массы функционирующих нефронов зарегистрировано увеличение уровня АД, экспрессии микроРНК‑21 в миокарде и толщины межжелудочковой перегородки (по данным ЭхоКГ). В этой же группе отмечено уменьшение конечного систолического размера левого желудочка и систолической экскурсии кольца митрального клапана. Заключение. Данные, полученные в настоящем исследовании, указывают на потенциальную роль миРНК‑21 в развитии концентрического ремоделирования левого желудочка при сокращении числа функционирующих нефронов. Своеобразие этого ремоделирования миокарда заключается в преобладании собственно гипертрофии миокарда над фиброзными изменениями. Тем не менее конкретные механизмы участия данной микроРНК в патогенезе перестройки сердца в такой ситуации требуют дальнейших исследований.</p></abstract><trans-abstract xml:lang="en"><p>Background and objective. Currently, the role of miRNA‑21 in the development of heart and kidney damage and their interaction remains unclear. Therefore, the aim of this work is to assess the impact of changes in the expression of microRNA‑21 in myocardial tissue in the development of cardiac remodeling with chronic reduction in the mass of active nephrons in the experiment. Design and methods. Wistar drain rats were divided into two groups. The first (control) group included nine falsely operated animals. The second (n = 9) group included rats with step-by-step resection of 5/6 renal tissue. After 4 months after surgery, blood pressure (BP) was measured, heart ultrasound (echocardiography, EchoCG) was performed and the level of relative expression of microRNA‑21 in myocardial tissue was determined. Results. The rats with an experimental decrease in the mass of functioning nephrons, showed significantly higher levels of BP, microRNA‑21 expression in the myocardium and the thickness of the interventricular septum (according to EchoCG). They also demonstrated smaller end-systolic dimension of the left ventricle and systolic motion of the mitral valve ring. Conclusions. Our data indicate the potential role of miRNA‑21 in the development of concentric left ventricular remodeling while reducing the number of functioning nephrons. This remodeling is characterized by the prevalence of myocardial hypertrophy over fibrosis. However, the specific mechanisms linking microRNA in the pathogenesis of heart remodeling require further research.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сокращение числа функционирующих нефронов</kwd><kwd>микро РНК-21</kwd><kwd>ремоделирование миокарда</kwd><kwd>эксперимент</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nephron number reduction</kwd><kwd>microRNA‑21</kwd><kwd>myocardial remodeling</kwd><kwd>experiment</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">Ichii O, Horino T.
