ABSTRACT
Objective To observe the effect and mechanism of quercetin on the proliferation of rat hepatic stellate cell(HSC)induced by TGF-β1.Methods HSC was isolated by orthotopic hepatic perfusion with collagenase Ⅳ.MTT assay was used to detect the inhibitory effect of quercetin on the proliferation of HSC.The expression of typeⅠcollagen in HSC was detected by ELISA.The effect of quercetin on the expression of typeⅠcollagen,Smad2 and Smad7 mRNA in HSC was detected by real-time quantitative PCR.The expression of type Ⅰ collagen,Smad2 and Smad7 protein in HSC was detected by Western blot.Results Quercetin could inhibit the proliferation of HSC,down-regulated the expression of type Ⅰ collagen,Smad2 mRNA and protein,and Smad7 mRNA and protein expression were significantly up-regulated(all P<0.05).Conclusion The anti-hepatic fibrosis effect of quercetin may be related to its blocking TGF-β1/Smad pathway of HSC and blocking the activation and proliferation of HSC.
