Скелетные мышцы являются одной из наиболее сложных тканей для трансфекции, в связи с чем актуальна разработка подходов к доставке генетических конструкций для целей генной терапии наследственных нервно-мышечных заболеваний (НМЗ).Цель: изучение комплексов ДНК/ПЭИ с анионным пептидным покрытием как средства доставки ДНК в клетки в физиологических условиях, а также в мышечные ткани.Методы. Изучены физико-химические (размер, заряд, устойчивость к полианионам), токсические (резазуриновый тест) и трансфекционные (экспрессия генов lacZ и GFP) свойства тройных комплексов ДНК и полиэтиленимина, покрытых глутаматбогатыми полипептидами. Для экспериментов in vivo использовали мышей линии C57BL/10J mdx.Результаты. Продемонстрировано, что разработанные комплексы ДНК/ПЭИ/полипептид нетоксичны, устойчивы к релаксации, вызванной полианионами, и могут обеспечивать доставку генетических конструкций в клетки и мышечные ткани.Заключение. Исследованные тройные комплексы продемонстрировали высокую эффективность доставки маркерных генов в мышечную ткань и в дальнейшем могут быть использованы для доставки генных конструкций для терапии НМЗ.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. Skeletal muscles are one of the most complex tissues for transfection, and therefore the development of approaches to the delivery of genetic constructs for the purposes of gene therapy of hereditary neuromuscular diseases (NMD) is relevant.Aim: the study of DNA complexes/PEI with anionic peptide coating as vehicles of delivering DNA to cells under physiological conditions, as well as to muscle tissues.Methods. Physicochemical (size, charge, resistance to polyanions), toxic (resazurin test), and transfection (lacZ and GFP gene expression) triple complexes of DNA and polyethylenimine coated with glutamate-rich polypeptides were studied. C57BL/10J mdx mice were used for in vivo experiments.Results. It has been demonstrated that the developed DNA/PEI/polypeptide complexes are non-toxic, resistant to relaxation caused by polyanions, and can ensure the delivery of genetic constructs to cells and muscle tissues.Conclusions. The studied triple complexes demonstrated high efficiency of delivering marker genes to muscle tissue and can later be used to deliver gene constructs for the treatment of NMD.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>доставка ДНК</kwd><kwd>полиэтиленимин</kwd><kwd>генная терапия</kwd><kwd>анионное покрытие</kwd><kwd>устойчивость к сыворотке</kwd><kwd>мышечная дистрофия Дюшенна</kwd></kwd-group><kwd-group xml:lang="en"><kwd>DNA delivery</kwd><kwd>polyethylenimine</kwd><kwd>gene therapy</kwd><kwd>anionic coating</kwd><kwd>serum resistance</kwd><kwd>Duchenne muscular dystrophy</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование проводится в рамках темы ФНИ № 1024032800068-4-3.2.2</funding-statement><funding-statement xml:lang="en">The research is funded by the Ministry of Education and Science, grant № 1024032800068-4-3.2.2.</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">Lu Q.L., Bou-Gharios G., Partridge T.A.
