This study aimed to reveal whether modulation of NRP-1 by rosuvastatin (RT) prevents AGE-induced renal injury via targeting RAGE/matrix metalloproteinase-2 (MMP-2) signaling in diabetic rats. Treatment with RT ameliorated the altered level of markers of glycemic control, renal injury, cholesterol, triglyceride (TG) and hepatic HMG-CoA reductase activity; the level of circulatory carboxymethyl-lysine (CML) and the accumulation of fluorogenic-AGEs in renal tissue was reduced; the expression of renal NRP-1, a checkpoint target, was stimulated; the transcription of RAGE, NFκB-2, TGF-β1 and MMP-2 was suppressed; the circulatory carbonyl content (CC) and paraoxonase-1 (PON-1) activity was ameliorated, and renal histopathological features were attenuated as evidenced by improved glomerular appearance, Bowman’s space and abundant podocytes in kidneys. In conclusion, RT exhibited the potential to counteract diabetes and AGE-induced renal pathologies via stimulation of NRP-1, suppression of RAGE, and of genes responsible for ECM disintegration (MMP-2) and the inflammatory response (NFκB-2).</p> ER -
