Investigating the Anti-inflammatory Effects of Rutin in Carbon Tetrachloride-induced Hepatotoxicity: Role of TLR4/MyD88/NFκB Signaling Pathway Modulation

Objectives Rutin protects and stabilizes hepatocytes and is used to treat hepatitis, liver cirrhosis, and other diseases. However, there is little evidence to suggest that Rutin is associated with CCl 4 -induced hepatotoxicity. In this study, we investigated the effects of Rutin on CCl 4 -induced liver inflammation and discussed in vivo and in vitro mechanisms. Materials and Methods CCl 4 was used to induce liver inflammation, and Rutin was used for intervention in mice. Then the body weight, liver weight, and liver inflammation of all mice were measured. Western blotting and RT-PCR were used to assess TLR4/MyD88/NFκB inflammation signaling pathways and inflammatory gene expression. Finally, TLR4 was activated in primary hepatocytes to verify the above signal pathways. Findings CCl 4 mice developed liver function damage and liver inflammation. Further investigations showed that the inhibitory effects of Si on inflammation were mediated by TLR4/MyD88/NFκB inflammation signaling pathways inhibition. Primary hepatocyte studies also confirmed the participation of these signaling pathways and proteins. Significance Rutin improved CCl 4 -induced liver inflammation. Such mechanisms may be related to TLR4/MyD88/NFκB inflammation signaling pathways.
