Antiangiogenic strategies are promising tools for cancer treatment and several other disorders. In this sense, phospholipases A2 (PLA2s) from snake venom have been described to possess antiangiogenic properties. In this study, we evaluated both in vitro and ex vivo antiangiogenic effects induced by BnSP-7, a Lys49 PLA2 isolated from Bothrops pauloensis snake venom. BnSP-7 was able to inhibit endothelial cell (HUVEC) proliferation, which was indeed confirmed by a modulation of cell cycle progression. Interestingly, BnSP-7 also inhibited the adhesion and migration of HUVECs and blocked in vitro angiogenesis in a VEGF-dependent manner, an important proangiogenic factor. Finally, BnSP-7 was capable of inhibiting sprouting angiogenic process through an ex vivo aortic ring assay. Taken together, these results indicate that BnSP-7 has potent in vitro and ex vivo antiangiogenic effect.
