Then, we detected the in vitro effects of U2-AuNP in U87-EGFRvIII cell lines and the in vivo antitumor effects of U2-AuNP in GBM-bearing mice. Furthermore, we explored the inhibition mechanism of U2-AuNP in U87-EGFRvIII cell lines.Results: We found that U2-AuNP inhibits the proliferation and invasion of U87-EGFRvIII cell lines and prolongs the survival time of GBM-bearing mice. We found that U2-AuNP can inhibit the EGFR-related pathway and prevent DNA damage repair in GBM cells.Conclusion: These results reveal the promising potential of U2-AuNP as a drug candidate for targeted therapy in GBM.Keywords: SELEX, EGFRvIII, GBM, therapyPeng LLiang YZhong XLiang ZTian YLi SLiang JWang RZhong YShi YZhang XDove Medical PressarticleselexegfrviiigbmtherapyMedicine (General)R5-920ENInternational Journal of Nanomedicine, Vol Volume 15, Pp 1363-1372 (2020)
