Abstract :

Choroidal neovascularisation is the primary cause of blindness in a variety of common retinal diseases including retinopathy of prematurity, age related macular degeneration, proliferative diabetic retinopathy, among other vascular diseases. Angioinhibitory therapies are starting to give hopeful results in these ocular diseases. In this study the angioinhibitory activity of endogenous metabolite derived from extra cellular matrix was analyzed in-vitro and in-vivo. Mouse choroidal endothelial cells treated with different doses of endogenous metabolite and performed in-vitro proliferation, migration and tube formation assays. Matrix metalloproteinase-2 (MMP-2) activation and MMP-2/endogenous metabolite complex formation were studied using different methods. In-vitro angioinhibitory effects of endogenous metabolite were studies in different mice models. Endogenous metabolite demonstrated anti-proliferative activity and inhibits mouse choroidal endothelial cells migration, tube formation in-vitro. Endogenous metabolite binds pro-MMP-2 and inhibits its activation mediated by both membrane-type-1 MMP and 4-amino-phenyl mercuric acetate in-vitro. Endogenous metabolite also confirmed that significant inhibition of integrin dependent and independent in-vivo and in-vivo angiogenesis.
