BACKGROUND AND THE PURPOSE OF THE STUDY The combination of angiotensin II receptor antagonists and HMG CoA reductase inhibitors have shown to confer renoprotection.The purpose of this study was to find out the renoprotective effects of telmisartan and atorvastatin in combination and in monotherapy of Streptozotocin (STZ) induced diabetic nephropathy in rats. METHODS Diabetes was induced by i....

Cyclic nucleotide signal transduction pathways are an emerging research field in kidney disease. Activated cell surface receptors transduce their signals via intracellular second messengers such as cAMP and cGMP. There is increasing evidence that regulation of the cGMP-cGMP-dependent protein kinase 1-phosphodiesterase (cGMP-cGK1-PDE) signaling pathway may be renoprotective. Selective PDE5 inhib...

Adrenocorticotropic hormone (ACTH) has a renoprotective effect in chronic kidney disease; however, its effect on acute kidney injury (AKI) remains unknown. In a rat model of tumor necrosis factor (TNF)-induced AKI, we found that ACTH gel prevented kidney injury, corrected acute renal dysfunction, and improved survival. Morphologically, ACTH gel ameliorated TNF-induced acute tubular necrosis, as...

Hypoxia in the tubulointerstitium has been thought to play pivotal roles in the pathophysiology of acute renal failure and the progression of chronic kidney disease. Pre-induction of hypoxia-inducible and renoprotective gene expression may protect subsequent ischemic injury. This study evaluated the efficacy of cobalt, which inhibits HIF-1 degradation and increases the expression level of hypox...

BACKGROUND Renoprotective actions of angiotensin receptor blockers are not well established in normotensive, low-grade proteinuric glomerular diseases. We examined the effect of low-dose telmisartan (LT) and high-dose telmisartan (HT) versus conventional antihypertensive therapy in the rat anti-Thy1.1 model of glomerulonephritis. METHODS Rats were randomized on Day 4 after disease induction t...

It is well documented that angiotensin (Ang) II contributes to kidney disease progression. The protease prolyl carboxypeptidase (PRCP) is highly expressed in the kidney and may be renoprotective by degrading Ang II to Ang-(1-7). The aim of the study was to investigate whether renal PRCP protein expression and activity are altered in two-kidney, one-clip (2K1C) Goldblatt hypertensive mice. Left ...

We recently demonstrated the use of in vitro expanded kidney-derived mesenchymal stem cells (KMSC) protected peritubular capillary endothelial cells in acute renal ischemia-reperfusion injury. Herein, we isolated and characterized microparticles (MPs) from KMSC. We investigated their in vitro biologic effects on human endothelial cells and in vivo renoprotective effects in acute ischemia-reperf...

Cisplatin is used as a potent anticancer drug, but it often causes nephrotoxicity. Bee venom (BV) has been used for the treatment of various inflammatory diseases, and its renoprotective action was shown in NZB/W mice. However, little is known about whether BV has beneficial effects on cisplatin-induced nephrotoxicity and how such effects might be mediated. In the present study, the BV-injected...

Numerous trials have shown that chronic kidney disease increases the risk of cardiovascular disease. Dyslipidemias have been shown to accelerate progression of kidney disease. Statins have assumed a pivotal role in management of hyperlipidemia. However their effect on renal function is still not fully understood. Some clinical trials have shown some renoprotective effect of statins but there is...
