| abstractText | Bombina variegata 8 (Bv8), also known as prokineticin-2 (PK-2), is a potent pro-angiogenic factor. However, its role in retinal neovascularization (RNV) remains unknown. In this study, we explored the role of Bv8 in the pathogenesis of RNV. We found that the expression of Bv8 was significantly increased in two different models of retinal neovascularization: the oxygen-induced retinopathy (OIR) mouse model and the rhodopsin promoter (rho)/VEGF transgenic mouse model. Neutralization of Bv8 by intravitreal injections of its antibody, not only inhibited retinal and subretinal neovascularization but also decreased the mRNA and protein levels of several pro-angiogenic factors. Our in vitro assay showed that recombinant human Bv8 (RhBv8) protein promoted human retinal microvascular endothelial cells (HRECs) tube-formation, cell proliferation and vascular endothelial growth factor receptor 1 (VEGFR1) and receptor 2 (VEGFR2) expression. Our findings suggest that Bv8 could be used as a novel target for the treatment of RNV-related ocular diseases. |
