Recent data show evidence that lipid rafts (LR) proteins could be involved in the formation of exosomes and the sorting of proteins that make up the exosomal cargo. Such data are available for flotillins, structural and functional components of flatted rafts. The presence of the main component of caveolar rafts, caveolin-1 (Cav-1), has been shown in exosomes produced by some cancer cells; however, its possible participation in the regulation of the protein composition of exosomes has not been studied previously.</p><p><bold>Materials and methods.</bold> Knockdown of Cav-1 by transduction of a lentiviral vector expressing precursors of short hairpin ribonucleic acid to Cav-1; isolation (by ultracentrifugation) and analysis (transmission electron microscopy, nanoparticle tracking analysis) of extracellular vesicles (EVs) from non-small cell lung cancer cells (NSCLC) H1299; analysis of proteins in cells and in EVs by immunoblotting.</p><p><bold>Results</bold>. Analysis of the effect of Cav-1 expression on the composition of EV proteins associated with exosome biogenesis revealed a decrease in the level of Alix and TSG101, an increase in the level of LR proteins and the absence of changes in the level of tetraspanin CD9.</p><p><bold> Conclusion.</bold> The obtained data demonstrate a Cav-1-dependent changes in the composition of EVs, indicating a change in the ratio of vesicles formed by the various molecular mechanisms.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение</bold>. Данные исследований последних лет свидетельствуют о том, что белки, входящие в состав липидных рафтов, могут быть задействованы в формировании экзосом и отборе белков, входящих в состав экзосомального карго. Такие данные получены для флотиллинов, структурно-функциональных компонентов плоских рафтов. Для кавеолина-1 (Cav-1), основного компонента кавеолярных рафтов, показано присутствие в экзосомах некоторых опухолевых клеток, однако его возможное участие в регуляции белкового состава экзосом ранее не исследовалось.</p><p><bold>Материалы и методы</bold>. Нокдаун Cav-1 проводили методом трансдукции лентивирусного вектора, экспрессирующего предшественников малых шпилечных рибонуклеиновых кислот к Cav-1. Экстраклеточные везикулы (ЭКВ) выделяли из клеток линии Н1299 немелкоклеточного рака легких методом дифференциального ультрацентрифугирования. Препараты ЭКВ верифицировали с помощью трансмиссионной электронной микроскопии (анализ размера и морфологии) и методом анализа траекторий движения наночастиц (среднеразмерное распределение и концентрация). Для анализа экзосомальных маркеров и Cav-1 в клетках и ЭКВ применяли метод иммуноблоттинга.</p><p><bold>Результаты.</bold> Анализ влияния экспрессии Cav-1 на состав белков ЭКВ, ассоциированных с биогенезом экзосом, выявил снижение уровня Alix и TSG101, повышение уровня белков липидных рафтов и отсутствие изменений уровня тетраспанина CD9.</p><p><bold>Заключение.</bold> Полученные данные демонстрируют Cav-1-зависимое изменение состава ЭКВ, свидетельствующее об изменении соотношения везикул, образованных с помощью различных молекулярных механизмов. </p></trans-abstract><kwd-group xml:lang="en"><kwd>exosomes</kwd><kwd>lipid rafts</kwd><kwd>flotillin</kwd><kwd>stomatin</kwd><kwd>caveolin-1</kwd><kwd>Alix</kwd><kwd>TSG101</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>экзосомы</kwd><kwd>липидные рафты</kwd><kwd>флотиллин</kwd><kwd>стоматин</kwd><kwd>кавеолин-1</kwd><kwd>Alix</kwd><kwd>TSG101</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The study was performed with the support of Russian Foundation for Basic Research (project No. 18-04-00038А).</funding-statement><funding-statement xml:lang="ru">Исследование проведено при поддержке Российского фонда фундаментальных исследований (проект № 18-04-00038А).</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Soung Y.H., Nguyen T., Cao H. et al.
