Abstract
Emodin inhibited expression of both transforming growth factor β1 (TGFβ1)- and phorbol ester (PMA)-induced tissue inhibitors of metalloproteinase-1 (TIMP-1) in an immortalized rat hepatic stellate cell line, HSC-T6, by Western blot and reverse transcription polymerase chain reaction. Reporter gene assays showed that emodin reduced both basal and PMA-induced activated protein-1 (AP-1) promoter activities. Electrophoretic mobility shift assay revealed that emodin reduced AP-1 DNA binding activities in HSC-T6 cells. AP-1 components analysis showed that emodin also attenuated JunD mRNA expression. Furthermore, emodin markedly inhibited TGFβ1-induced p42/p44 mitogen-activated protein kinase phosphorylation but did not alter PMA induction. We conclude that emodin effectively inhibits PMA- and TGFβ1-stimulated TIMP-1 expression in hepatic stellate cells by suppressing the AP-1 signaling pathway and extracellular signal-regulated kinase activation, respectively. These data provide new insight into the cellular and molecular mechanisms of emodin against liver fibrosis.
