OBJECTIVE: To investigate the effect of luteolin on the proliferation and collagen expression of hepatic stellate cells.
METHODS: The effect of luteolin on proliferation and collagen synthesis of hepatic stellate cells isolated from the liver of Wistar rats were determined by (3)H-TdR and (3)H-Pro, and procollagen gene expression was also detected by DIG-labeled gene probe and in situ hybridization.
RESULTS: The proliferation and collagen synthesis were significantly and dose-dependently inhibited by luteolin when the concentrations reached 10 micromol/L and 20 micromol/L respectively (t=2.542, P<0.05; t=3.650, P<0.01). The type I, III procollagen mRNA expression was decreased by 25 micromol/L luteolin, in which the type I procollagen mRNA was reduced with statistical significance (x(2)=6.850, P<0.01).
CONCLUSIONS: Luteolin inhibits the proliferation and collagen expression of hepatic stellate cells in vitro. It may have a preventive or therapeutic role in liver fibrosis.
