KDR and glioblastoma: The present study thus provides the first piece of evidence that VMP1 can promote angiogenesis through VEGFA‐VEGFR2 signaling and endothelial cell activation, and that VMP1‐OE GBM cells could activate the angiogenic switch by upregulating VEGFR2 expression, possibly through the production of soluble pro‐angiogenic factors.
