Following iridoid compounds, geniposide (present, i.a., in the fruit of Gardenia jasminoides) may inhibit TGF-β1-induced EMT in hepatic fibrosis by suppressing the TGF-β/Smad and ERK-mitogen-activated protein kinase (MAPK) signaling pathways [14]. This evidence concerns the gene TGFB1 and Hepatic fibrosis.
