The condition is deeply associated with oxidative stress and inflammation. Monomethyl fumarate (MMF) has manifested antioxidant and immunomodulatory properties. The aim of current study was to evaluate protective effects of MMF in sepsis-induced hepatic dysfunction.Main methodsSepsis was induced by cecal ligation and puncture (CLP). Wistar rats were assigned to one of sham, CLP, CLP + dexamethasone (as positive control of inflammation) and CLP + MMF groups. Levels of serum IL-1β, IL-6, IL-10, AST, ALT and γ‑GT were quantified. Furthermore, Hepatic levels of GSH and MDA and mRNA expression of TNF and NFKBIA along with hepatic protein level of TLR-4 were assessed. Also, histopathological study of liver was carried out to evaluate hepatic injuries.Key findingsSeptic rats demonstrated risen levels of IL-1β, IL-6, IL-10, AST, ALT and γ‑GT, while treatment with dexamethasone or MMF attenuated these levels. Moreover, enhancements in protein level of TLR-4 and mRNA levels of TNF and NFKBIA were observed in CLP rats. These elevations were mitigated in CLP-induced rats that...
