Existing methods of therapy allows to insignificantly prolong patient’s lifespan with this diagnosis. Thus, it is necessary to search for new approaches and develop new principals of glioblastoma therapy. In this paper, we describe the principle of impact on glioblastoma tumor cells, which consists in targeted inhibition of the proliferation of L1CAM-positive cells using aptamers. L1CAM is considered to be a marker of tumor glioma stem cells, the presence of which in a tumor may be responsible for resistance to therapy. As a result of the work, the yly12 aptamer was selected from a panel of aptamers for L1CAM and its antiproliferative effect was shown, which was more pronounced on human glioblastoma cells with increased expression of L1CAM. Thus, the effect can solve the problem of glioblastoma cell resistance and prevent tumor recurrence by influencing cancer glioma stem cells.</p></abstract><trans-abstract xml:lang="ru"><p>Глиобластома остается неизлечимой формой опухоли головного мозга. Существующие методы терапии способны только незначительно продлить жизнь пациентов с таким диагнозом. Поэтому необходимо искать новые подходы и разрабатывать новые способы терапии глиобластомы. В данной работе мы описываем принцип воздействия на опухолевые клетки глиобластомы, заключающийся в направленном ингибировании пролиферации L1CAM-позитивных клеток с помощью аптамеров. L1CAM принято считать маркером опухолевых стволовых клеток глиомы, наличие которых в опухоли может отвечать за резистентность к терапии. В результате работы из панели аптамеров к L1CAM был отобран аптамер yly12, для которого был продемонстрирован антипролиферативный эффект, более выраженный на клетках глиобластомы человека с повышенной экспрессией L1CAM. Таким образом, оказываемое воздействие может решить вопрос устойчивости клеток глиобластомы и предотвратить рецидивирование опухоли за счет влияния на опухолевые стволовые клетки глиомы.</p></trans-abstract><kwd-group xml:lang="en"><kwd>glioblastoma</kwd><kwd>cancer glioma stem cells</kwd><kwd>proliferation</kwd><kwd>L1CAM</kwd><kwd>aptamer</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>глиобластома</kwd><kwd>опухолевые стволовые клетки глиомы</kwd><kwd>пролиферация</kwd><kwd>L1CAM</kwd><kwd>аптамеры</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Министерство науки и высшего образования Российской Федерации</institution></institution-wrap><institution-wrap><institution xml:lang="en">Ministry of Science and Higher Education of the Russian Federation</institution></institution-wrap></funding-source><award-id>075–15–2021–1343</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Almeida Magalhães T. de, Cruzeiro G.
