Спинальная мышечная атрофия (СМА) – тяжелое нервно-мышечное заболевание, для которого актуальной остаются разработка терапевтических подходов и оптимизация доставки терапевтических молекул в клетки.</p></sec><sec><title>Цель</title><p>Цель: исследовать эффективность коррекции сплайсинга гена SMN2 антисмысловыми олигонуклеотидами, доставленными в комплексе с пептидным носителем, в культуры фибробластов больных СМА. </p></sec><sec><title>Методы</title><p>Методы. Культура фибробластов больного СМА, антисмысловые РНК олигонуклеотиды, пептидный носитель.

Мы показали эффективность антисмысловых олигонуклеотидов (АСО) для коррекции сплайсинга гена SMN2, доставленных пептидным носителем, содержащим лиганд к рецепторам на поверхности клеток-мишеней. Было обнаружено значимое увеличение доли полноразмерных транскриптов SMN и телец-близнецов, содержащих белок SMN, в результате доставки комплексов АСО:носитель в культуры фибробластов СМА.</p></sec><sec><title>Заключение</title><p>Заключение. Данные результаты перспективны для развития способов невирусной доставки терапевтических молекул в клетки больных СМА.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Spinal muscular atrophy is a severe neurodegenerative disease for which the development of therapeutic approaches and optimization of the delivery of therapeutic molecules into cells remains relevant.</p></sec><sec><title>Aim</title><p>Aim: to investigate the effectiveness of correcting the splicing of the SMN2 gene with antisense oligonucleotides delivered in combination with a peptide carrier into fibroblast cultures of SMA patients.</p></sec><sec><title>Methods</title><p>Methods. Fibroblast culture of SMA patient, antisense RNA oligonucleotides, peptide carrier.

We have shown the effectiveness of antisense oligonucleotides (ASO) for correcting the splicing of the SMN2 gene delivered by a peptide carrier containing a ligand to receptors on the surface of target cells. A significant increase in the proportion of full-length SMN transcripts and gems containing the SMN protein was found as a result of the delivery of ASO:carrier complexes to SMA fibroblast cultures.</p></sec><sec><title>Conclusion</title><p>Conclusion. These results are promising for the development of methods for the non-viral delivery of therapeutic molecules into the cells of SMA patients.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>спинальная мышечная атрофия</kwd><kwd>генная терапия</kwd><kwd>невирусная доставка</kwd><kwd>пептидные носители</kwd><kwd>ген SMN2</kwd><kwd>коррекция сплайсинга</kwd><kwd>антисмысловые олигонуклеотиды</kwd></kwd-group><kwd-group xml:lang="en"><kwd>spinal muscular atrophy</kwd><kwd>gene therapy</kwd><kwd>non-viral delivery</kwd><kwd>peptide carriers</kwd><kwd>SMN2 gene</kwd><kwd>splicing correction</kwd><kwd>antisense oligonucleotides</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">Lefebvre S., Bürglen L., Reboullet S., et al.
