- Paper Abstract
- Geniposide (GEN) is a natural antioxidant and anti-inflammatory product and plays an important role in the treatment of diabetes and diabetic complications. To explore the biological functions and mechanism of GEN in diabetic retinopathy (DR), we constructed the in vitro and in vivo model of DR by using primary cultured mouse retinal Muller cells and C57BL/6 mice, respectively. We found that GEN inhibited ROS accumulation, NF-kappaB activation, Muller cell activation, and inflammatory cytokine secretion both in vitro and in vivo, which is probably mediated through the Nrf2 pathway. Exendin (9-39) (EX-9), an antagonist of glucagon-like peptide-1 receptor (GLP-1R), abolished the protective effect of GEN on high glucose- (HG-) induced Muller cells. Additionally, GEN decreased hyperglycemia-induced damage to Muller cells and blood-retinal barrier in the retinas of mice with DR. We demonstrated that GEN was capable of protecting Muller cells and mice from HG-induced oxidative stress and inflammation, which is mostly dependent on the Nrf2 signaling pathway through GLP-1R. GEN may be an effective approach for the treatment of DR.
