| description | <h4>Purpose</h4>This study aims to explore glucose-6-phosphate dehydrogenase (G6PD) activity in diabetic retinopathy (DR) and its correlation with inflammatory factors, elucidating the regulatory role of G6PD in DR pathology.<h4>Methods</h4>A total of 151 T2DM patients were divided into three groups: diabetes without retinopathy (DNR, n = 59), non-proliferative retinopathy (NPDR, n = 46) and proliferative retinopathy (PDR, n = 49). Plasma G6PD activity was measured by a Randox G6PD kit and compared between these groups. Then the G6PD activity was correlated with inflammatory cytokines and metabolic parameters in these patients. A STZ-induced diabetic rat model was established, G6PD activity was validated by western blot and immunofluorescence staining in the retina of this model.<h4>Results</h4>Plasma G6PD activity decreased in the order of DNR, NPDR and PDR groups (P<0.01). G6PD activity was negatively correlated with IL-6, IL-8, TNF-α, cholesterol, and LDL (r = -0.1625, -0.1808, -0.1865, -0.1747, r = -0.1807, P<0.05). Multiple regression analysis showed TNF-α, IL-6, and LDL were independent related factors for G6PD. Logistic regression analysis showed G6PD, triglyceride, cholesterol, IL-8, TNF-α, and macular edema were influencing factors for T2DM with DR. Western Blot analysis indicated a significant reduction of G6PD expression in the retina, and immunofluorescence staining showed distribution of G6PD especially in the retinal endothelium cell decreased.<h4>Conclusion</h4>G6PD may play an important role in DR occurrence and progression, with decreased expression correlating closely with lipid metabolism and inflammatory factors. |
