Ocular neovascularization underlies major blinding eye diseases such as "wet" age-related macular degeneration (AMD). Despite the successes of treatments targeting the vascular endothelial growth factor (VEGF) pathway, resistant and refractory patient populations necessitate discovery of new therapeutic targets. Using a forward chemical genetic approach, we identified the heme synthesis enzyme ...
v-Integrin antagonists block neovascularization in various species, whereas 20% of v-integrin null mice are born with many normal looking blood vessels. Given that blockade of v-integrins during angiogenesis induces p53 activity, we utilized p53 null mice to elucidate whether loss of p53 can compensate for v-integrin function in neovascularization of the retina. Murine retinal vascularization w...
PURPOSE Transforming growth factor-beta (TGF-beta) plays an important role in the development of choroidal neovascularization. TGF-beta transduces signals through the mediation of type I and type II receptors. We investigated the expression of TGF-beta receptors in a normal rat retina and a model of experimentally induced choroidal neovascularization. METHODS Choroidal neovascularization was ...
AIM To compare the effect of topically administered and subconjunctivally injected bevacizumab on experimental corneal neovascularization in rats for two weeks after treatment. METHODS Twenty-eight Sprague-Dawley rats were divided into four groups of 7 animals. Each corneal center of right eye was cauterized with silver/potassium nitrate for 8s. After corneal burning, bevacizumab (12.5mg/mL) ...
BACKGROUND AND PURPOSE Histological data associate proliferation of adventitial vasa vasorum and intraplaque neovascularization with vulnerable plaques represented by symptomatic vascular disease. In this observational study, the presence of carotid intraplaque neovascularization and adventitial vasa vasorum were correlated with the presence and occurrence of cardiovascular disease (CVD) and ev...
Purpose To determine the prevalence of subclinical nonexudative neovascularization and associated choroidal vascular changes in the fellow eyes of patients presenting with unilateral typical exudative AMD (tAMD) or polypoidal choroidal vasculopathy (PCV) using indocyanine green angiography (ICGA) and swept-source (SS) optical coherence tomography angiography (OCT-A). Methods We recruited pati...
Corneal neovascularization leads to blurred vision, thus in vivo visualization is essential for pathological studies in animal models. Photoacoustic (PA) imaging can delineate microvasculature and hemodynamics noninvasively, which is suitable for investigating corneal neovascularization. In this study, we demonstrate in vivo imaging of corneal neovascularization in the mouse eye by optical-reso...
PURPOSE This study sought to determine whether a vascular endothelial growth factor receptor 1 (VEGFR1)-specific morpholino could induce the alternative splicing of Flt-1 pre-mRNA to downregulate membrane-bound Flt-1 (mFlt-1) and increase the production of soluble Flt-1 (sFlt-1), thereby limiting angiogenesis and inflammation in a mouse corneal suture injury model. METHODS A murine corneal su...
eales' disease is an idiopathic obliterative retinal vasculopathy that is treated with laser photocoagulation, and/or vitrectomy. in order to determine visual outcomes and regression of retinal neovascularization following scattered peripheral retinal photocoagulation, and/or vitrectomy in cases with eales' disease, we did a retrospective study of the records of these patients treated...
Choroidal neovascularization (CNV) is one of the hallmark symptoms Wet Age-related Macular Degeneration (wAMD) and DiabeticRetinopathy(DR) which involves formation neoangiogenic i.e. new abnormal blood vessels emerging from choroidal protruding through retinal layer. The current management wAMD intravitreal injections anti-VEGF such as ranibizumab aflibercept. We hypothesized delivery small mol...
