Diabetic retinopathy (DR) is a frequent microvascular complication of diabetes, and one of the most common causes of legal blindness in the world. Epigallocatechin-3-gallate (EGCG) produces an anti-oxidative and anti-inflammatory effect against various human s. In this study, we determined the effect of EGCG on a human retinal endothelial cell (HREC) line. The cell viability was determined by a standard MTT assay, while the cell cycle and apoptosis rate were analyzed by flow cytometry. Inflammatory marker expression was detected by enzyme-linked immunosorbent assay. Treatment of HRECs with EGCG (20 and 40 mM) led to a significant decrease in the apoptosis rate (2.35± 0.56 and 1.24 ± 0.32%). The culture supernatant of cells treated with high glucose concentrations showed significantly higher levels of TNF-? (598.7 ± 89.7 vs 193.2 ± 38.5 pg/mL; P
