Abstract | AIMS: MAIN METHODS: Effects of glycyrrhizin and its metabolite, glycyrrhetinic acid, on collagen promoter activity were examined by using transgenic reporter mice harboring alpha2(I) collagen gene ( COL1A2) promoter. Their effects on the TGF-beta/Smad signaling pathway were studied by cell transfection assays and immunofluorescence studies using cultured hepatic stellate cells. KEY FINDINGS: SIGNIFICANCE: The results provide a molecular basis for the anti-fibrotic effect of glycyrrhizin treatment.
