The Novel VEGF121-VEGF165 Fusion Attenuates Angiogenesis and Drug Resistance via Targeting VEGFR2-HIF-1α-VEGF165/Lon Signaling Through PI3K-AKT-mTOR Pathway.

In conclusion, our data demonstrated that the chimeric VEGF121-VEGF165 arrests the tube formation of endothelial cells and interferes with tumor cell growth, migration and invasion, suggesting that it could be a potential drug as an angiogenesis antagonist in cancer therapy. The VEGF121-VEGF165 targets not only paracrine angiogenic cascade of endothelial cells but also autocrine PI3K-AKT-mTOR-mediated VEGFR2-HIF-1α- VEGF165/Lon signaling that drives drug resistance in tumor cells. Our study will open up the patient opportunities to combat drug resistance to antiangiogenic therapy. PMID: 26882030 [PubMed - in process]
