ABSTRACT
Cyclophosphamide is an anticancer drug with a wide spectrum of clinical uses, but its typical side effects are multiple complications, including nephron toxicity. The possible molecular mechanism of the nephroprotective action of sesamin (SM) against cyclophosphamide (CP) induced renal toxicity was investigated in rats by understanding oxidative stress and inflammatory cytokines. In this study, rats were arbitrarily grouped into the following four groups: a normal control group (CNT); a CP-induced toxicity group; a treatment group with two doses of sesamin SM10 and SM20; a group with sesamin (SM20) alone. A single dose of CP (150 mg/kg body, i.p.) was administered on day 4 of the experiments, while treatment with SM was given orally for seven days from day 1. The group treated with SM showed a significant protective effect against CP-induced renal damage in rats. Treatment with SM significantly increased the antioxidant enzymes (GSH, CAT, and SOD) and reduced malondialdehyde (MDA) levels. Thus, SM significantly overcame the elevated kidney function markers (creatinine, blood urea nitrogen, and uric acid) by attenuating oxidative stress. The SM also significantly reduced the elevated cytokines (IL-1ß and TNFα) and caspase-3 in the treated group. Histopathological studies confirmed the protective effect of sesamin (SM) on CP-induced nephrotoxicity. In conclusion, the current findings support the nephroprotective effect of sesamin against CP-induced renal injury.
