Abstract:

Diabetic retinopathy is one of the most severe microvascular complications of diabetes mellitus, which can lead to irreversible blindness. The main pathological changes of DR are breakdown of blood-retinal barrier and neovascularization. Vascular endothelial growth factor (VEGF) is considered to be the most important intraocular neovascularization factor. Recent researches show that endoplasmic reticulum stress (ERS) and hypoxia-inducible factor-1 (HIF-1) can regulate the expression of VEGF and advance the progress of diabetic retinopathy together. This paper reviews the latest advance of the regulation mechanism of ERS and HIF-1 to VEGF.

Key words: diabetic retinopathy, endoplasmic reticulum stress, hypoxia-inducible factor-1, vascular endothelial growth factor
