Özet

Cisplatin is an antineoplastic agent used in the treatment of various types of solid tumors. Despite the dose-dependency of its antineoplastic effect, the high risk for nephrotoxicity frequently precludes the use of higher doses. alpha-Linolenic acid (ALA), a carboxylic acid having three cis double bonds, is an essential fatty acid required for health and can be acquired via foods that contain ALA or supplementation of foods high in ALA. Previous studies have shown that ALA demonstrates anti-cancer, anti-inflammatory, and anti-oxidative effects. In this study, we show the protective effect of ALA on cisplatin-induced renal toxicity associated with oxidative stress in mice using biochemical parameters. The mice were randomly assigned into four experimental groups. Group 1 (control group) were administered physiological saline solution for 9 days; group 2 (ALA group) received 200 mg/kg alpha-linolenic acid via gavage for 9 days; group 3 (CIS group) received 100 mg/kg intraperitoneal (i.p.) CIS for 9 days; and group 4 (ALA + CIS group) received 100 mg/kg i.p. CIS and followed by ALA 200 mg/kg via gavage for 9 days. Alpha-linolenic acid significantly reduced the expression of myeloperoxidase (MPO), phospholipase A(2) (PLA(2)), cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) in the ALA + CIS group compared to the CIS group. Furthermore, catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GPx) quantities were significantly elevated in the ALA + CIS group when compared to the CIS group. ALA significantly decreased the levels of Bax and cleaved caspase-3, while significantly increasing the level of bcl-2, an anti-apoptotic protein, in the ALA + CIS group than in the CIS group. Finally, histopathological examination in renal tissue showed that the significant edematous damage induced by CIS administration alone was reduced in ALA + CIS group. In conclusion, our findings show that ALA is beneficial to CIS-induced nephrotoxicity in mice via its anti-inflammatory and anti-oxidative effects.
