Abstract Title:
Wogonin attenuates liver fibrosis via regulating hepatic stellate cell activation and apoptosis.
Abstract:
Liver fibrosis is the representative features of liver chronic inflammation and the characteristic of early cirrhosis. To date, effective therapy for liver fibrosis is lacking. Recently, Traditional Chinese Medicine (TCM) has attracted increasing attention due to its wide pharmacological effects and more uses in clinical. Wogonin, as one major active constituent of Scutellaria radix, has been reported it plays an important role in anti-inflammatory, anti-cancer, anti-viral, anti-angiogenesis, anti-oxidant and neuro-protective effects. However, the anti-fibrotic effect of wogonin is never covered in liver. In this study, we evaluated the protect effect of wogonin in liver fibrosis. Wogonin significantly attenuated liver fibrosis both in CCl-induced mice and TGF-βactivated HSCs. Meanwhile, wogonin can enhances apoptosis of TGF-βactivated HSC-T6 cell from rat and LX-2 cell from human detected by flow cytometry. Additionally, wogonin can largely enhances cle-caspase3, cle-caspase9 expression and the ratio of Bax/Bcl-2 in T6 cells. Pro-apoptosis effect of wogonin in vivo was further verified in situ. In conclusion, wogonin can attenuate liver fibrosis via regulating the activation and apoptosis of hepatic stellate cells, and may be an effective drug to treat and prevent liver fibrosis.
