Studies on the protective effect of flaxseed oil on cisplatin-induced hepatotoxicity

Abstract

Cisplatin (CP) is known as one of the most potent chemotherapeutic antitumor drugs. The tissue-specific toxicity of CP in the kidneys is well documented. However, at higher doses less common toxic effects such as hepatotoxicity may arise. Since CP remains one of the most effective antineoplastic drug used in chemotherapy, strategies to protect tissues against CP toxicity are of clinical interest. Recently, ω-3 polyunsaturated fatty acids (PUFAs) from certain plants/seeds notably flaxseed have shown numerous health benefits. In view of this, the present study investigates the protective effect of flaxseed oil (FXO) on CP-induced damage in liver. Rats were pre-fed normal diet and the diet rich in FXO for 10 days and then a single dose of CP (6 mg/kg body weight) was administered intraperitoneally while still on diet. Serum/urine parameters, enzymes of carbohydrate metabolism and oxidative stress were analyzed. CP caused perturbation of the antioxidant defense as reflected by the decrease in the activities of catalase, superoxide dismutase and glutathione peroxidase. Further the activities of various enzymes involved in glycolysis, tricarboxylic acid cycle, gluconeogenesis and hexose monophosphate shunt pathways were determined and were found to be differentially altered by CP treatment. However, these alterations were ameliorated in CP-treated rats fed on FXO. Present results show that dietary supplementation of FXO in CP-treated rats ameliorated CP-induced hepatotoxic and other deleterious effects due to its intrinsic biochemical/antioxidant properties.

Influence of L-arginine on Cisplatin-Induced Hepatotoxicity in both normally Fed and Protein Malnourished Rats

“…These results are in agreement with the study reported by Naqshbandi et al [51]. This observation is consistent with a recent report by Yadav, (2015) that showed CDDP administration induced significant increase in serum ALT, AST and significant decrease in serum total protein, and albumin levels [30].…”

Pu-erh Tea Powder Preventive Effects on Cisplatin-Induced Liver Oxidative Damage in Wistar Rats

“…That's to say, one of the mechanisms about cisplatininduced liver injury is oxidative damage. Naqshbandi A et al (2012) showed that dietary supplementation of flaxseed oil in cisplatin-treated rats ameliorated cisplatininduced hepatotoxic and other deleterious effects due to its intrinsic biochemical/antioxidant properties (Naqshbandi A et al, 2012). Gaona-Gaona L et al (2011) investigated the protective effect of sulforaphane pretreatment against cisplatin-induced liver and mitochondrial oxidant damage in rats.…”

Anti-tumor effects of polyphenolic compounds of Camellia sinensis, Nigella sativa, Matricaria chamomilla and Triticum aesativum against Ehrlich ascites carcinoma mouse model

“…Our results showed that hepatic and renal GPx activity in tumor-bearing mice and CIS treated mice significantly decreased as compared to normal control. These results may be explained based on that CIS exerts its toxic effects by inducing the generation of ROS which can interact with cellular membranes to cause lipid peroxidation, and thereby alter the structure and function of membranes [30].…”
