Silymarin ameliorates diazinon-induced subacute nephrotoxicity in rats via the Keap1-Nrf2/heme oxygenase-1 signaling pathway.
Purpose: The goal of the current study was to clarify the potential molecular mechanism underlying the protective effects of silymarin (SIL) administration against diazinon-induced subacute nephrotoxicity, with a special emphasis on the role of the Kelch-like-associated protein-1 (Keap1)-nuclear factor erythroid 2-related factor 2 (Nrf2)-heme oxygenase-1 (HO-1) signaling pathway in minimizing the oxidative stress induced by diazinon (DZN).
Methods: Five equal groups of thirty adult male Wistar rats were created at random. Group 1 (G1) was maintained under typical control conditions and administered saline intragastrically (I/G) once daily for 4 weeks; G2 was administered olive oil I/G for 4 weeks; G3 was I/G administered silymarin daily for 4 weeks; G4 was I/G administered diazinon daily for 4 weeks. G5 was I/G administered silymarin daily 1 h before the I/G administration of the diazinon for 4 weeks. Blood samples were collected at the end of the experiment for the determination of complete blood cell count, and kidney function tests. Kidney specimens were collected for the evaluation of the oxidative markers, mRNA gene expression, protein markers, and histopathological examination.
Results: SIL reduced the renal dysfunction caused by DZN by restoring urea and creatinine levels, as well as oxidative indicators. Although the expression of Keap-1 was also elevated, overexpression of Nrf2 also enhanced the expression of HO-1, a crucial target enzyme of Nrf2.
Conclusions: SIL is hypothesized to potentially aid in the prevention and management of nephrotoxicity caused by DZN.
期刊介绍：
The journal Forensic Toxicology provides an international forum for publication of studies on toxic substances, drugs of abuse, doping agents, chemical warfare agents, and their metabolisms and analyses, which are related to laws and ethics. It includes original articles, reviews, mini-reviews, short communications, and case reports. Although a major focus of the journal is on the development or improvement of analytical methods for the above-mentioned chemicals in human matrices, appropriate studies with animal experiments are also published.
Forensic Toxicology is the official publication of the Japanese Association of Forensic Toxicology (JAFT) and is the continuation of the Japanese Journal of Forensic Toxicology (ISSN 0915-9606).
