血管内皮生长因子与色素上皮衍生因子在糖尿病猕猴视网膜病变早期的表达
Expression of VEGF and PEDF in early-stage retinopathy in diabetic Macaca mulatta
摘要
Abstract
Objective To explore the expression of vascular endothelial growth factor (VEGF) and pigment epithelium-derived factor (PEDF) in early stage of diabetic retinopathy (DR) in Macaca mulatta.Methods Three diabetic Macaca mulattas induced by high-fat diet were identified for early stage of diabetic retinopathy according to the fasting plasma glucose,hemoglobin Alc (HbA1c),fundus photograph and duration of diabetes,with another 3 age-matched healthy Macaca mulattas as control.The expression of VEGF and PEDF in the retinas of Macaca mulatta were detected by quantitative real-time PCR and immunohistochemistry.Result In early stage of diabetic retinopathy,VEGF mRNA and protein of the diabetic group were both significantly increased compared with the control group (P<0.05).PEDF expression at both mRNA and protein levels was significantly decreased in diabetic Macaca mulattas compared with the control group (P<0.01 and 0.05 respectively).Conclusion Retinal VEGF expression is increased and PEDF expression is decreased in early stage of diabetic retinopathy,suggesting their involvement in the occurrence of diabetic retinopathy and their value in assisting in the early diagnosis.关键词
