Abstract
AIM: To study the antifibrotic effects of matrine in vitro a nd in vivo. METHODS: Rat hepatic stellate cell HSC-T6 and mouse fibroblast cell NIH3T3 proliferation stimulated with serum and platelet-derived growth factor (PDGF) was measured b y crystal violet staining assay. Collagen synthesis stimulated with serum and transforming growth factor beta1 (TGF-beta1) was determined by [3H]proline incorporation. Liver fibrosis was induced by carbon tetrachloride (CCl4) in rats an d evaluated with plasma hyaluranic acid level and hepatic hydroxyproline content. RESULTS: Matrine (1-2 mmol/L) markedly reduced serum-driven proliferation and collagen synthesis of HSC-T6 cells as well as NIH3T3 cells. PDGF-driven proliferative activity and TGF-beta1-driven collagen synthesis in HSC-T6 cel ls were attenuated by matrine (0.25-2 mmol/L) in a concentration-dependent manner. In vivo matrine (50 mg/kg and 100 mg/kg) significantly decreased serum hyaluranic acid levels and hepatic hydroxyproline contents in rats treated with CCl4. CONCLUSION: Inhibition of PDGF and TGF-beta1 actions on hepatic stellate cell by matrine might provide a possible mechanism of its antifibrotic activities.
