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 CCl4-induced mice and TGF-β1 activated HSCs. Meanwhile,
wogonin can enhances apoptosis of TGF-β1 activated 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.
