%0 Journal Article %T Protective Effect of Valsartan on Podocyte Injury in Rats with Diabetic Nephropathy %J American Journal of Life Sciences %@ 2328-5737 %D 2018 %X To investigate the mechanism of valsartan protecting podocytes and inhibiting renal injury in diabetic rats. The rat model of diabetic nephropathy was induced by combination of valsartan and high-sugar and high-fat diet. The urinary protein content, renal index, inflammatory and antioxidant indexes in the kidney, renal pathological changes and podocyte holes were investigated. Membrane WT1 and P-Cadherin protein expression levels. Compared with the model group, the 24h urine protein content of valsartan was significantly decreased (P<0.05). Valsartan significantly inhibited the body weight of the model group (P<0.01), and significantly inhibited The increase of renal index (P<0.05); the high and middle doses of valsartan could significantly reduce the levels of IL-¦Â, TNF-¦Á and IL-6 in rat kidney (P<0.05-0.01). The valsartan high and middle dose groups significantly reduced MDA content in rat kidney (P<0.05), and significantly increased SOD activity (P<0.05). HE and PAS staining showed that valsartan was used in model group rats. The pathological changes were alleviated, and the glomerular morphology returned to normal. The protein expression of WT1 and P-Cadherin in the kidney of DN rats by Western blot showed that P- in the kidney tissue of valsartan rats. The expression levels of Cadherin and WT1 protein were significantly increased (P<0.05). Valsartan can regulate the expression of podocyte membrane proteins WT1 and P-Cadherin to protect podocytes, and then repair renal function and anti-diabetic nephropathy %K Valsartan %K Diabetic Nephropathy %K Podocyte %K P-Cadherin %K WT1 Protein %U http://www.sciencepublishinggroup.com/journal/paperinfo?journalid=118&doi=10.11648/j.ajls.20180603.12
