Abstract :

Doxorubicin (DOX) is a widely used antineoplastic drug with several toxic effects. We investigated the protective effect of co-administration of Baicalein (BL; a flavonoid) and losartan (LT; angiotensin receptor blocker) on DOX-induced nephrotoxicity. Male Wistar albino rats were divided into these seven groups (n=6): 1) Control group; 2) DOX group; 3) DOX+BL group (BL, 10 mg/kg/ day); 4) DOX+LT group (LT, 7 mg/kg/day) and 5) DOX+LT+BL(10) group. After two weeks of LT and BL treatment, a dose of DOX was administered. Serum renal markers such as creatinine and urea levels were significant (P <0.001) elevated in DOX challenged group compared to normal animals. Renal pro-inflammatory cytokines including tumour necrosis factor-α (TNFα), interleukin (IL-1β and IL-6) levels were significantly (P<0.001) increased while an anti-inflammatory cytokine IL-10 levels were markedly (P<0.001) increased in DOX challenged group compared to controls. Oxidative stress biomarkers including thiobarbituric acid reaction substances (TBARS) and glutathione (GSH) in renal cells were significantly (P<0.001) increased and decreased compared to control group respectively. Enzymatic activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and glutathione-S-transferase (GST) in renal cells were significantly (P<0.01) decreased in DOX challenged rats compared to normal. In addition, renal protein expressions and inflammatory activities of caspase-3, n-nitric oxide syntheses (nNOS), inducible nitric oxide synthase (iNOS), endothelial nitric oxide synthase(eNOS) and nuclear factor kappa-B (NF-κB) p65 were significantly (P<0.001) increased in DOX challenged rats when compared to control animals. While the DOX-induced increase in serum renal markers, proinflammatory cytokines and biomarkers was alleviated by BL and/or LT treatment and showed the most potent protective effects. Our study demonstrates remarkable anti-oxidative and anti-inflammatory effects of BL and LT in rodents challenged with DOX.
