ABSTRACT
This research aimed to explore the impact of nodosin on lipopolysaccharide (LPS)-induced acute kidney injury (AKI) in rats. The study involved administering nodosin orally at doses of 2 and 4 mg/kg body weight orally to rats for 7 days before induction of AKI. Toward the end of the study, urine, blood, and kidneys were gathered from the rats to undergo biochemical and molecular examination after sacrificing them. Serum Scr, BUN, urine NGAL, and KIM-1 levels were significantly decreased in nodosin-treated AKI rats. Besides, nodosin administration resulted in a significant reduction in kidney MDA and 4-HNE levels. In contrast, antioxidant enzymes such as SOD, CAT, GPx, and GST levels increased, as well as Nrf2, NQO1, and HO-1 levels increased, while Keap-1 mRNA levels decreased in AKI rats. In addition, AKI rats treated with nodosin reversed excessive ferroptosis in the kidneys of LPS-induced AKI rats, as evidenced by increased mRNA and protein levels of GPX4, SLC7A11, and FTH-1. The administration of nodosin significantly reduced levels of inflammatory markers including TLR4, MYD88, NF-κB p65, IkKß, and IL-1ß, while IL-10 levels increased in the AKI-induced rats. Besides, histopathological changes were reduced in AKI-induced rats treated with nodosin. Nodosin proves highly beneficial in safeguarding the kidney from AKI by regulating oxidative stress, inflammation, and ferroptosis. The treatment of AKI could greatly benefit from this option.
