摘      要：Objective:Advanced glycation end-products (AGEs) exert inflammatory and oxidative stress insults to produce diabetic nephropathy mainly through the receptor for AGEs (RAGE).This study aimed to assess the effect of atorvastatin on diabetic nephropathy via soluble RAGE (sRAGE) and RAGE expressions in the rat ***:Thirty-two male Sprague-Dawley rats were divided into four groups based on the presence or absence of streptozotocin-induced diabetes with or without atorvastatin treatment (10 mg/kg for 24 weeks).Serum sRAGE and glycated albumin (GA) levels were measured with enzyme-linked immunosorbent assay (ELISA) and improved bromocresol purple *** AGEs,RAGE,endogenous secretory RAGE (esRAGE),and sRAGE were determined with reverse transcription-polymerase chain reaction (RT-PCR) and Western ***:Mesangial expansion and microalbuminuria were aggravated in diabetic rats,and improved with atorvastatin *** sRAGE levels were lower in diabetic than in normal *** atorvastatin treatment,serum and renal sRAGE levels were up-regulated,while renal RAGE expression was decreased in diabetic rats,associated with a reduction in accumulation of AGEs,though renal esRAGE mRNA expression was not significantly ***:Atorvastatin exerted a beneficial effect on diabetic nephropathy with reduced AGE accumulation,down-regulating RAGE expression and up-regulating sRAGE in the kidney.
