A BMP7 Variant Inhibits Tumor Angiogenesis In Vitro and In Vivo through Direct Modulation of Endothelial Cell Biology

2015

Bone morphogenetic proteins (BMPs), members of the TGF-β superfamily, have numerous biological activities including control of growth, differentiation, and vascular development. Using an in vitro co-culture endothelial cord formation assay, we investigated the role of a BMP7 variant (BMP7v) in VEGF, bFGF, and tumor-driven angiogenesis. BMP7v treatment led to disruption of neo-endothelial cord formation and regression of existing VEGF and bFGF cords in vitro. Using a series of tumor cell models capable of driving angiogenesis in vitro, BMP7v treatment completely blocked cord formation. Pre-treatment of endothelial cells with BMP7v significantly reduced their cord forming ability, indicating …

Abstract B5: A BMP7 variant inhibits angiogenesis in vitro and in vivo in part by downregulating VEGFR2 and FGFR1 expression in endothelial cells.

2013

Abstract Glioblastoma multiforme (GBM), the most aggressive glioma, requires active angiogenesis for growth and survival. Bone morphogenetic proteins (BMPs), members of the TGF-β superfamily, have numerous biological activities including control of growth, differentiation, and vascular development. Previously, we demonstrated the use of a BMP7 variant (BMP7v) to differentiate glioblastoma stem-like cells (GSLCs) and significantly reduce their tumorigenic potential (Tate and Pallini et al. 2012). Using an in vitro co-culture endothelial cord formation assay, a surrogate of angiogenesis, and its cognate in vivo model, we investigated the role of BMP7v in VEGF, basic FGF (bFGF), tumor-driven a…
