Abstract

Angiogenesis is a key physiological process that plays a key role in glioblastoma (GBM) progression and displays therapeutic resistance to antiangiogenic therapies. In this study, we aimed to identify whether vascular endothelial growth factor receptor 2(VEGFR2)monoclonal antibodies(mab)could inhibit tumorigenicity and the formation of vascular mimicry (VM) in GBM. The bioinformatic analysis from TCGA, CGGA, and TCPA databases and Immunohistochemistry (IHC) revealed that VEGFR2 is highly expressed in glioma tissues and results in a poor prognosis and is positively associated with VM markers (CD34 and PAS). The anti-VEGFR2 monoclonal antibodies(MSB0254)could inhibit the invasion, migration, and VM formation of U251 and primary glioma cells in vitro. In vivo, MSB0254 (m) could not only inhibit the growth of transplanted tumors of U251 and GL261 cells, but also significantly inhibit the expression of CD34, VEGFR2, Ki67, MMP2, MMP9 and reduce the expression of CD34/PAS and inhibit VM formation. The VEGFR2 monoclonal antibody could inhibit the angiogenesis and tumor growth of GBM by blocking the signaling pathway mediated by VEGFR2. It may become a new supplementary treatment for GBM.
