Summary: | The invention relates to medicine, particularly to oncology, and can be used to treat cancer.According to the invention, epidermal growth factor receptor (EGFR) expression and phosphorylation is increased in cancer cells treated with anti-clusterin antibodies. Such treatment is also accompanied with the reappearance of an epithelial phenotype of the cancer cell, as determined by an increased E-cadherin expression at the surface of cancer cells. Clusterin inhibitors may thus induce reversal of the epithelial to mesenchymal phenotype and restore sensitivity of cancer cells to EGFR inhibitors. Combinations of a clusterin inhibitor and an EGFR as well as their use in the treatment of cancer are thus provided in the present invention.
Invenţia se referă la medicină, în special la oncologie, şi poate fi utilizată pentru tratamentul cancerului.Conform invenţiei, expresia receptorului factorului de creştere epidermică (EGFR) şi fosforilarea se intensifică în celulele canceroase tratate cu anticorpi anti-clusterină. Un astfel de tratament este de asemenea însoţit de reapariţia unui fenotip epitelial al celulelor canceroase, aşa cum este ilustrat printr-o expresie crescută a E-caderinei la suprafaţa celulelor canceroase. Inhibitorii clusterinei pot astfel induce inversarea fenotipului epitelial în cel mezenchimal şi restabili sensibilitatea celulelor canceroase faţă de inhibitorii EGFR. Astfel, în prezenta invenţie sunt oferite combinaţii dintre un inhibitor al clusterinei şi un inhibitor EGFR, precum şi utilizarea acestora pentru tratamentul cancerului.
Изобретение относится к медицине, в частности к онкологии, и может быть использовано для лечения рака.Согласно изобретению, экспрессия рецептора эпидермального фактора роста (EGFR) и фосфорилирование усиливаются в раковых клетках, обработанных анти-клустериновыми антителами. Такое лечение также сопровождается повторным появлением эпителиального фенотипа раковых клеток, как показано на повышенной экспрессии Е-кадгерина на поверхности раковых клеток. Ингибиторы клустерина могут, таким образом, вызвать инверсию эпителиального фенотипа в мезенхимальный и восстановить чувствительность раковых клеток к ингибиторам EGFR. Таким образом, в настоящем изобретении предложены сочетания ингибитора клустерина и ингибитора EGFR, а также их использование для лечения рака. |
