چکیده انگلیسی
Diabetic retinopathy (DR) remains a leading cause of blindness in adults with diabetes mellitus. The pathogenesis of DR is a multifactorial process, and excessive oxidative stress and apoptosis in retinal endothelial cells (RECs) play vital roles. In this study, RECs were treated with 25â¯mM glucose for three days, and we found that miR-145 was significantly downregulated in high glucose (HG)-treated RECs. Overexpression of miR-145 attenuated the HG-induced apoptosis, oxidative stress and inflammatory cytokines secretion in RECs. Besides, miR-145 overexpression also attenuated the increased TLR4 expression and NF-κB p65 nuclear translocation in HG-treated RECs. Luciferase reporter assay showed that miR-145 could specifically bind to the 3â²UTR of TLR4, and overexpression of TLR4 abrogated the beneficial effects of miR-145 in HG-treated RECs. Therefore we suggested that miR-145 might be a potential therapeutic target for DR.
