Abstract: | AbstractContext: Acute kidney injury (AKI) is considered a major public health concern in today’s world. Sepsis‐induced AKI is large as a result of exposure to lipopolysaccharide (LPS) that is the major outer membrane component of Gram‐negative bacteria. Sesamin is the main lignan of sesame seeds with multiple protective effects.Objective: In this research, we tried to demonstrate the protective effect of sesamin pretreatment in LPS-induced mouse model of AKI.Methods: LPS was injected at a single dose of 10?mg/kg (i.p.) and sesamin was given p.o. at doses of 25, 50, or 100?mg/kg, one hour prior to LPS.Results: Treatment of LPS-challenged mice with sesamin reduced serum level of creatinine and blood urea nitrogen (BUN) and returned back renal oxidative stress-related parameters including glutathione (GSH), malondialdehyde (MDA), and activity of catalase and superoxide dismutase (SOD). Moreover, sesamin alleviated inappropriate changes of renal nuclear factor-kappaB (NF-κB), toll-like receptor 4 (TLR4), cyclooxygenase-2 (COX2), tumor necrosis factor α (TNFα), interleukin-6, DNA fragmentation (an apoptotic index), and nuclear factor (erythroid-derived 2)-like 2 (Nrf2). In addition, sesamin diminished magnitude of kidney tissue damage due to LPS.Conclusion: In summary, sesamin could dose-dependently abrogate LPS-induced AKI via attenuation of renal oxidative stress, inflammation, and apoptosis. |
