Симптоматическая терапия мышечной дистрофии Дюшенна не способна предотвратить развитие болезни, поэтому надежды в лечении заболевания сосредоточены в области генной терапии, позволяющей компенсировать генетические дефекты путем введения в клетку нуклеиновых кислот.Цель: изучение свойств пептидных носителей на основе катионных и анионных пептидов для улучшения доставки ДНКконструкций в мышечные клетки.Методы. В работе были использованы методы культивирования миобластов С2С12, трансфекция клеток, анализ токсических свойств с помощью резазуринового теста, проточная цитофлуорометрия. Для экспериментов in vivo использовали мышей линии C57BL/10J mdx.Результаты. Большинство разработанных комплексов не является токсичным для миобластов C2C12, осуществляет эффективную доставку плазмидной ДНК в мышечные клетки in vitro и in vivo.Выводы. Самым эффективным оказался нуклеопептидный комплекс, содержащий наибольшее количество экранирующего покрытия в своем составе, что повышает его стабильность во внеклеточном матриксе скелетной мускулатуры и таким образом обеспечивает наибольшую эффективность доставки ДНК.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. Symptomatic therapy for Duchenne muscular dystrophy is unable to prevent the development of the disease, so hopes for treating the disease are concentrated in the field of gene therapy, which allows compensating for genetic defects by introducing nucleic acids into the cell.Aim: study of the properties of cationic and anionic peptides to improve the DNA delivery to muscle cells.Methods. Methods of C2C12 myoblast cultivation, cell transfection, analysis of toxic properties using a resazurin test, and flow cytofluorometry were used in the work. C57BL/10Jmdx mice were used for in vivo experiments.Results. Most of the developed complexes are not toxic to C2C12 myoblasts and effectively deliver plasmid DNA to muscle cells both in vitro and in vivo.Conclusions. The most effective was the nucleopeptide complex containing the largest amount of shielding coating in its composition, which increases its stability in the extracellular matrix of skeletal muscles and, thus, ensures the greatest efficiency of DNA delivery.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>генная терапия</kwd><kwd>доставка ДНК</kwd><kwd>нуклеопептидные комплексы</kwd><kwd>экранирующее анионное покрытие</kwd><kwd>мышечная дистрофия Дюшенна</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gene therapy</kwd><kwd>DNA delivery</kwd><kwd>nucleopeptide complexes</kwd><kwd>anionic shielding coating</kwd><kwd>Duchenne muscular dystrophy</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование проводится в рамках темы ФНИ № 1024032800230-9-3.2.2</funding-statement><funding-statement xml:lang="en">The research is funded by the Ministry of Education and Science, grant № 1024032800230-9-3.2.2.</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">Guiraud S., Aartsma-Rus A,.
