OBJECTIVE
To determine whether RNA interference (RNAi) could block hypoxia-induced upregulation of vascular endothelial growth factor (VEGF) in human corneal epithelial cells in vitro and inhibit and regress injury-induced murine corneal neovascularization in vivo.
METHODS
siRNA selected on the
OBJECTIVE
To determine whether subunits of VEGF receptor-1 coupled with an endoplasmic reticulum retention signal can block hypoxia-induced upregulation of VEGF secretion in corneal epithelial cells and block murine corneal angiogenesis induced by corneal injury.
METHODS
Human corneal epithelial
OBJECTIVE
To examine the effect of rapamycin on the proliferation and the migration of human umbilical vein endothelial cells (HUVECs) and on the corneal neovascularization in the corneal alkaline burn murine model.
METHODS
HUVEC proliferation, migration, and apoptosis were examined after treatment
OBJECTIVE
To determine whether Flt24K, a recombinant construct of domains 2 to 4 of VEGFR-1 (Flt) coupled with an endoplasmic reticulum retention signal (KDEL) can bind VEGFR-2 and induce apoptosis, unfolded protein response (UPR), and regression of injury-induced corneal
OBJECTIVE
To examine the effect of recombinant canstatin protein on the corneal neovascularization (CorNV) in an alkaline burn-induced CorNV model.
METHODS
This study involved 50 C57BL/6 mice. CorNV was induced by an alkaline burn of the corneas with 1 N NaOH under general anesthesia. Beginning 24 h
OBJECTIVE
The antiangiogenic effect of an antisense oligodeoxynucleotide (ODN) targeting insulin receptor substrate (IRS)-1 was evaluated on rat corneal neovascularization.
METHODS
Eyes with neovessels were treated with subconjunctival injections of IRS-1 antisense oligonucleotide (ASODN), IRS-1
Corneal avascularity is critical for corneal transparency; therefore, a tailored process has been presumed to minimize corneal neovascularization (NV). In most cell types, the transcription of vascular endothelial growth factor (VEGF) is up-regulated, and the stability of VEGF mRNA is A 39-year-old man suffered from corneal neovascularization, through to result from hypoxia caused by improper use of polymethylmethacrylate (PMMA) hard contact lenses. The condition was successfully treated by oxygenation of the corneas under swimming goggles.
The present study aimed to investigate the effects of diabetes mellitus (DM) on the generation of experimental corneal neovascularization (CrNV) and choroidal neovascularization (ChNV). Diabetes was induced in mice by intraperitoneal injection of streptozotocin (STZ). Experimental CrNV and ChNV were
OBJECTIVE
Abnormally induced angiogenesis and lymphangiogenesis are associated with human diseases, including neovascular eye disease. Substances that inhibit these processes may have potential as an attractive therapeutic strategy for these diseases.
METHODS
In vitro and in vivo angiogenesis and/or
Corneal neovascularization may result in loss of corneal transparency and blindness. However, developing successful and inexpensive medical treatments for corneal neovascularization remains an unresolved issue. Recently, several studies have implicated miRNA functions in the regulation of cornea
Enhancer of zeste homolog 2 (EZH2), a well-known methyltransferase, mediates histone H3 lysine 27 trimethylation (H3K27me3) and plays a vital role in ophthalmological disease. However, its role in corneal neovascularization (CoNV) remains unclear. In vitro and in vivo models were assessed in
OBJECTIVE
Although overnight eye closure is known to result in hypoxia and release of potent angiogenic factors, even prolonged eye closure does not result in corneal neovascularization. This suggests that the closed eye tear film may contain factors that can impede neovascularization. Closed eye
Under healthy conditions, the cornea is an avascular structure which allows for transparency and optimal visual acuity. Its avascular nature is maintained by a balance of proangiogenic and antiangiogenic factors. An imbalance of these factors can result in abnormal blood vessel proliferation into
To investigate the in vivo angiogenic activity of placenta growth factor (PIGF) and its heterodimers with vascular endothelial growth factor (VEGF), the induction of neovascularization of these factors in the mouse cornea was studied. VEGF165 is sufficiently potent to stimulate new capillary growth
