GL-V9 ameliorates liver fibrosis by inhibiting TGF-O/smad pathway

Liver fibrosis is a wound-healing response that arises from various aetiologies. Flavonoid compounds have been proved of their anti-liver fibrosis effects. This study aimed to elucidate the protective effect and mechanism of flavonoid compound GL-V9 on CCl4-induced and DDC-induced liver fibrosis. Treatment with GL-V9 alleviated hepatic injury and exhibited a dramatic protection effect of liver fibrosis. Further experiments found that GL-V9 treatment inhibited extracellular matrix (ECM) expression. Activation of hepatic stellate cells (HSCs) is a central driver of fibrosis. GL-V9 could inhibit the activation of HSCs through directly binding to TGFORI, subsequently inhibit TGF-O/Smad pathway. In conclusion, this study proved that GL-V9 executed a protective effect on liver fibrosis by inhibiting TGF-O/Smad pathway.

Automated summary

This study aimed to investigate the protective effect and mechanism of flavonoid compound GL-V9 on CCl4-induced and DDC-induced liver fibrosis. Treatment with GL-V9 alleviated hepatic injury and exhibited a significant protective effect on liver fibrosis. Further experiments demonstrated that GL-V9 treatment inhibited extracellular matrix (ECM) expression and the activation of hepatic stellate cells (HSCs) through the TGF-O/Smad pathway.
