ABSTRACT Cisplatin-induced nephrotoxicity is related to an increase in oxidative stress in the kidney. Lycopene, a carotenoid found in tomatoes, is a potent dietary antioxidant. In the present study, we investigated the effect of the tomato lycopene complex against cisplatin-induced lipid peroxidation and nephrotoxicity in rats. Male Wistar rats (n = 28, 8 wk old, between 200-215 g) were divided into 4 groups: (a) control, (b) tomato lycopene complex (6 mg/kg, daily; consisting of 6% lycopene, 1.5% tocopherols, 1% phytoene and phytofluene, and 0.2% β-carotene), (c) cisplatin (7 mg/kg i.p., single dose), and (d) cisplatin + tomato lycopene complex. Cisplatin administration increased serum urea-N (171 vs. 37 mg/dl) and creatinine (1.80 vs. 0.42 mg/dl) and decreased body weight in comparison with the control rats (P < 0.001). Serum creatinine and urea-N levels were lower in rats treated with tomato lycopene complex + cisplatin compared with rats treated with cisplatin alone (P < 0.001). The renal tissue from the cisplatin-treated rats had greater malondialdehyde (MDA; 172 vs. 93 nmol/g) and 8-isoprostane levels (1810 vs. 610 pg/g) than that from the control rats (P < 0.001). Tomato lycopene complex prevented the rise of MDA and 8-isoprostane (P < 0.001). No measurable lycopene could be detected in the serum of the control and cisplatin-treated rats, whereas lycopene was observed in the serum of rats supplemented with tomato lycopene complex. Renal Bax protein expression was significantly higher in the cisplatin-treated rats than in the control rats, and tomato lycopene complex treatment significantly reduced Bax expression (P < 0.001). The expression of Bcl-2 was higher in tomato lycopene complex/cisplatin-treated rats than in the cisplatin-injected rats (P < 0.05). The expression of renal HSP60 and HSP70 was significantly lower in tomato lycopene complex + cisplatin-treated rats than in rats treated with cisplatin alone (P < 0.001). These results suggest that tomato lycopene complex has protective effects against cisplatin-induced nephrotoxicity and lipid peroxidation in rats.

    ABSTRACT: In the present study, we investigated the effects of lycopene on the expression of organic anion transporters (OATs), organic cation transporters (OCTs), and multidrug resistance-associated proteins (MRPs) of cisplatin-induced nephrotoxicity in rats. Twenty-eight 8-week-old Wistar rats were divided into four groups: control, lycopene-treated (6 mg/kg BW by oral gavage), cisplatin-treated (7 mg/kg BW, IP), and lycopene in combination with cisplatin-treated groups. In the presence of cisplatin, serum urea nitrogen (urea-N) (48.5 vs. 124.3 mg/dl) and creatinine (0.29 vs. 1.37 mg/dl) levels and the kidney efflux transporters MRP2 and MRP4 levels were significantly increased, whereas OAT1, OAT3, OCT1, and OCT2 levels in kidney were decreased in the treated rats compared with normal control rats. However, administration of lycopene in combination with cisplatin resulted in a reduction in the serum urea-N (124.3 vs. 62.4) and creatinine (1.37 vs. 0.40) levels and the kidney efflux transporters MRP2 and MRP4 proteins in the kidneys. Administration of lycopene to acute renal injury-induced rats largely upregulated the organic anion transporters (OAT1 and 3) and organic cation transporters (OCT1 and 2) to decrease the side effects of cisplatin. The present study suggests that lycopene synergizes with its nephroprotective effect against cisplatin-induced acute kidney injury in rats.

    ABSTRACT: The field of cancer research has been emerged in recent years for the development of specific drugs to cancer treatment. New agents with the ability to provide efficient treatment by reducing side effects has led to new opportunities for improving agents for cytotoxic therapies. While there are several drugs for colon cancer treatment, researchers are trying to evaluate new agents or combinations of existing ones which can be used efficiently. Schiff bases with a wide range of variety and biological properties including anticancer activity might be used for colon cancer treatment. In the current study, a novel schiff base derivative synthesized by our group was tested in vivo for colon cancer. In a model of azoxymethane (AOM) induced colorectal cancer, chemopreventive properties of schiff base was also analyzed in rats. While AOM induced de novo crypt formation, adenocarcinoma and dysplasia development, schiff base application reduced the number of aberrant crypt foci (ACF), dysplasia or adenocarcinoma. Analysis of the intestinal mucosa showed that peritoneal administration of SB complex not only decreased the protein expression of COX-2, Bcl-2 and NF-κB but also enhanced the Bax expression suggesting the apoptotic and anti-proliferative effects for this compound. Our findings showed that SB complex might be used for the colorectal cancer treatment. Further studies are highly warranted to obtain additional insights and identify mode of action for the schiff base.
