ARTICLE HIGHLIGHTS
Research background
Diabetic retinopathy (DR) is a serious and potentially blinding complication of diabetes mellitus.
Research motivation
We used an experimental animal model to find a more effective strategy for the treatment of DR.
Research objectives
The study aim was to evaluate the effect of intravitreal injection of recombinant human maspin on neovascularization in DR.
Research methods
An oxygen-induced retinopathy (OIR) model in mice was used to simulate neovascularization in diabetic retinopathy. On postnatal day P12, 0.5 µL of 0.05 mg/mL recombinant human maspin was injected into the vitreous cavity of maspin injection OIR group mice. The protein and mRNA expression of vascular endothelial growth factor (VEGF) and hypoxia-inducible factor 1-alpha (HIF-1α) in the retina were assayed. The numbers of vascular cell nuclei that broke through the inner limiting membrane were counted.
Research results
The results revealed that intravitreal injection of maspin inhibited neovascularization and reduced protein and mRNA expression of VEGF, HIF-1α in the retinal tissue of OIR model mice.
Research conclusions
Maspin inhibited neovascularization of DR by modulating the VEGF/HIF-1α pathway, providing a potential and effective strategy for the treatment of DR.
Research perspectives
Retinal neovascularization is one of the main pathological features of PDR. Inhibiting retinal neovascularization is a research focus.
