Alpha-linolenic acid confers protection on mice renal cells against cisplatin-induced nephrotoxicity.

ABSTRACT: 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. ?-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 A2 (PLA2), 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.

Project description:BackgroundNephrotoxicity remains a problem for patients who receive cisplatin chemotherapy. We retrospectively evaluated potential risk factors for cisplatin-induced nephrotoxicity as well as the potential impact of intravenous magnesium supplementation on such toxicity.Patients and methodsWe reviewed clinical data for 401 patients who underwent chemotherapy including a high dose (?60 mg/m2) of cisplatin in the first-line setting. Nephrotoxicity was defined as an increase in the serum creatinine concentration of at least grade 2 during the first course of cisplatin chemotherapy, as assessed on the basis of National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0. The severity of nephrotoxicity was evaluated on the basis of the mean change in the serum creatinine level. Magnesium was administered intravenously to 67 patients (17%).ResultsCisplatin-induced nephrotoxicity was observed in 127 patients (32%). Multivariable analysis revealed that an Eastern Cooperative Oncology Group performance status of 2 (risk ratio, 1.876; P?=?0.004) and the regular use of nonsteroidal anti-inflammatory drugs (NSAIDs) (risk ratio, 1.357; P?=?0.047) were significantly associated with an increased risk for cisplatin nephrotoxicity, whereas intravenous magnesium supplementation was associated with a significantly reduced risk for such toxicity (risk ratio, 0.175; P?=?0.0004). The development of hypomagnesemia during cisplatin treatment was significantly associated with a greater increase in serum creatinine level (P?=?0.0025). Magnesium supplementation therapy was also associated with a significantly reduced severity of renal toxicity (P?=?0.012).ConclusionsA relatively poor performance status and the regular use of NSAIDs were significantly associated with cisplatin-induced nephrotoxicity, although the latter association was marginal. Our findings also suggest that the ability of magnesium supplementation to protect against the renal toxicity of cisplatin warrants further investigation in a prospective trial.
