Using antibody raised in our laboratories that recognized phospho-VE-cadherin in VEGF-stimulated HUVECs (positive control; Figure 1G-HUVECs), phosphorylation on Y685 VE-cadherin was detected in all human glioblastoma tissues tested in this study (Figure 1G, GBM). This evidence concerns the gene VEGFA and glioblastoma.
