摘要

Cisplatin is the first platinum-containing anti-cancer drugs. Cisplatin notable side effect of nephrotoxicity limits its use in clinic. Meanwhile, arjunolic acid possesses anti-inflammatory properties and plays protective roles against chemically induced organ pathophysiology. This study was conducted to find out whether arjunolic acid could attenuate kidney damage in rats, and to elucidate its possible mechanism of action. Fifty rats were treated with cisplatin (10 mg/kg) in the presence/absence of 100 or 250 mg/ kg arjunolic acid. Arjunolic acid is given 1 h after cisplatin. Morphological changes were assessed in kidney sections stained with Hematoxylin/Eosin and Masson Trichrome. Kidney samples were used for measurements of transforming growth factor (TGF)-beta 1 and its type 1 receptor (TGF-beta R1), tumor necrosis factor (TNF)-alpha and interleukin (IL)-1 beta by ELISA. Gene expression NF kappa B was determined by real time-PCR. Kidney tissue apoptosis was assessed by measuring the activities of caspase-3/8/9. The renal protective effect of arjunolic acid was confirmed by approximately normal appearance of renal tissue and the relatively unaffected serum creatinine and urea levels. Furthermore, arjunolic acid showed dose dependent reduction in cisplatin-induced elevation in renal levels of TGF-beta R1, TGF-beta 1, TNF-alpha, IL-l beta and caspases. These findings demonstrated that arjunolic acid attenuates cisplatin nephrotoxicity either indirectly by enhancing body antioxidant activity or directly through several mechanisms, including inhibition of pro-inflammatory cytokines, blocking activation of TGF-beta 1, and anti-apoptotic effects.
