Abstract:
In this study,the relationship between the advanced glycation end products(AGEs) and the expressions of receptor for AGEs(RAGE),intercellular cell adhesion molecule-1(ICAM-1) was investigated.The diabetic rat model was reconstructed and the fluorescence method,RT-PCR and in-situ hybridization techniques were used to detect AGEs content and the expressions of RAGE and ICAM-1 gene in the aorta and cardiac tissues.The results showed that AGEs content in aortic and cardiac tissues increased(P<0.01) in diabetic rats; The expressions of RAGE and ICAM-1 enhanced (P<0.05~0.01) and were positively correlated with the quantity of AGEs accumulation(P<0.01) in the aorta and cardiac tissue.These parameters change in the diabetic rats can be improved with aminoglumine(AG) treatment.Suggesting that AGEs might induce RAGE and ICAM-1 expression.It's postulated that AGEs binding to RAGE play an important role to result in diabetic endothelial cells dysfunction and lesion.
