Aims: To evaluate the role of hyperoside in ameliorating retinal injury of DR rats and dysfunction of retinal endothelial cells (RECs) in high-glucose. Methods: RECs were cultured in varied groups including high-glucose and different concentrations of hyperoside. The viability, migration and tube formation of RECs, and the expressions of TGF-β1/miR-200b/VEGF in each group were assayed. Meanwhile, Sprague Dawley rats were used for DR modeling and treated by hyperoside. The tissue pathology of rat retina, and the expressions of TGF-β1/miR-200b/VEGF of retinal tissues in each group were tested. Results: Excessive proliferation, migration and tube formation of RECs were induced by high-glucose. The retinal pathological changes and vasculopathy in DR rats were more serious compared with normal rats. The expressions of TGF-β1 and VEGF in high-glucose-induced RECs group and DR rats retina were markedly up-regulated, but miR-200b levels were obviously down-regulated. However, hyperoside could significantly inhibit high-glucose-induced over-proliferation, migration and tube formation of RECs, alleviate retinal injury of DR rats, and reverse the expressions of TGF-β1/miR-200b/VEGF in high-glucose-induced RECs and DR rats retina, dose-dependently. Conclusions: Hyperoside could ameliorate DR rats retinal injury and high-glucose-induced RECs dysfunction by regulating TGF-β1/miR-200b/VEGF pathway.
