Choroidal neovascularisation (CNV) 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 type IV collagen was analyzed.Mouse choroidal endothelial cells (MCEC)
treated with different doses of metabolite and performed
proliferation, migration and tube formation assays. Matrix
metalloproteinase-2 (MMP-2) activation and MMP-2/metabolite complex formation were studied using different methods.
Endogenous metabolite demonstrated anti-proliferative activity and inhibits MCEC 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 (APMA)
. Angioinhibitory effects of metabolite were studied in mice model using LASER-
induced CNV method.
