Abstract
OBJECTIVE: Although cisplatin (CIS) acts as potent chemotherapy, nephrotoxicity still its major life-threatening side effect. The purpose of this study was to discuss and compare the renoprotective effects of curcumin (CUR) and etoricoxib (ETB) against CIS-induced nephrotoxicity. MATERIALS & METHODS: Thirty six adult female rats were divided equally into 6 groups: Group I (control), Group II (CIS) received cisplatin (7.5 mg/kg i.p), Group III (CUR) and group IV (ETB) received curcumin (200 mg/kg/day) or etoricoxib (10 mg/kg/day) respectively via gavage for seven continuous days. Group V (CIS + CUR) and Group VI (CIS + ETB) received curcumin (200 mg/kg/day) or etoricoxib (10 mg/kg/day) via gavage for seven continuous days. On the 4th day, the rats received cisplatin (7.5 mg/kg i.p) as a single injection 1 h after last curcumin or etoricoxib administration. At the assigned time, blood and tissue samples were collected for biochemical, histochemical, histopathological, immunohistochemical, and RT-PCR gene expression studies. RESULTS: Curcumin administration significantly decreased CIS-induced elevation of serum creatinine and blood urea nitrogen (BUN), and reversed oxidative stress markers; glutathione (GSH) and malondialdehyde (MDA) to control level. Suppression of inflammatory and apoptotic responses by CUR co-treatment was evidenced by decreased iNOS and BAX immunohistochemical reactions, and TNF-α and Caspase3 gene expressions which were detected by RT-PCR in kidney tissues. To our knowledge, this is the first time to discuss the effect of ETB on CIS induced nephrotoxicity. Although ETB reduced the previously mentioned inflammatory and apoptotic markers, its effect was less than that of CUR. Administration of ETB couldn't modify the disturbed levels of creatinine, BUN, GSH, and MDA. CONCLUSION: In conclusion, CUR provided a promising renoprotective effect against CIS induced nephrotoxicity. Further studies are recommended to approve or disapprove the protective role of ETB in CIS induced nephrotoxicity.
