1 Subconjunctival nano- and microparticles sustain retinal delivery of budesonide, a corticosteroid capable of inhibiting VEGF expression. Budesonide vascular endothelial growth factor A Homo sapiens
2 PURPOSE: The purpose of this study was to determine whether budesonide inhibits expression of vascular endothelial growth factor (VEGF) in a retinal pigment epithelial cell line (ARPE-19) and to determine whether subconjunctivally administered budesonide nano- and microparticles sustain retinal drug levels. Budesonide vascular endothelial growth factor A Homo sapiens
3 PURPOSE: The purpose of this study was to determine whether budesonide inhibits expression of vascular endothelial growth factor (VEGF) in a retinal pigment epithelial cell line (ARPE-19) and to determine whether subconjunctivally administered budesonide nano- and microparticles sustain retinal drug levels. Budesonide vascular endothelial growth factor A Homo sapiens
4 RESULTS: At concentrations devoid of cytotoxicity, budesonide inhibited VEGF secretion as well as mRNA expression in ARPE-19 cells in a dose-dependent manner. Budesonide vascular endothelial growth factor A Homo sapiens
5 RU486 treatment prevented budesonide-mediated inhibition of VEGF secretion and VEGF mRNA expression. Budesonide vascular endothelial growth factor A Homo sapiens
6 RU486 treatment prevented budesonide-mediated inhibition of VEGF secretion and VEGF mRNA expression. Budesonide vascular endothelial growth factor A Homo sapiens
7 CONCLUSIONS: Budesonide is capable of inhibiting VEGF expression through glucocorticoid receptor activity. Budesonide vascular endothelial growth factor A Homo sapiens
