Abstract

Diabetic nephropathy (DN) is the most frequent cause of the end-stage renal disease (ESRD) in about 33% of diabetic patients. The present study aimed to explore the renoprotective effects of simvastatin (SV) and rosuvastatin (RSU) on the kidney of streptozotocin (STZ)-induced diabetic Sprague-Dawley (SD) rat model. As a result of induction of diabetes, serum [cystatin C, transforming growth factor-beta (TGF-β), and 8-hydroxy-2' -deoxyguanosine (8-OHdG)] and tissue [interleukin 1 beta (IL-1β), interleukin 10 (IL-10), prostaglandin E2 (PGE2), cytochrome c, malondialdehyde (MDA), glutathione (GSH), glutathione disulfide (GSSG), GSH/GSSG ratio) markers showed significant increase than negative controls except tissue total glutathione (tGSH). Both SV and RSU significantly shifted the levels back toward near non-diabetic values. Both exerted the same renoprotective effect indicated by a significant decrease in cystatin C. However, SV significantly lowered IL-10, GSH/GSSG ratio, MDA, and 8-OHdG than RSU. Similarly, RSU significantly lowered cytochrome c and GSSG than SV. In conclusion, SV and RSU have differential renoprotective effects via alteration of growth factor, inflammatory, oxidative stress, DNA damage, and apoptotic signaling pathways.
