Structural Influence of Isothiocyanates on the Antioxidant Response Element (ARE)-Mediated Heme Oxygenase-1 (HO-1) Expression
2008
Purpose
Isothiocyanates (ITCs), existing abundantly in cruciferous vegetables, is one class of promising dietary cancer chemopreventive agents that possess strong cancer protective effects by modulation of phase II detoxifying/antioxidant enzyme activities. However, limited studies regarding to the structure-activity relationship (SAR) of ITCs on the induction of phase II detoxifying/antioxidant enzymes are reported. In this study, the effects of ten structurally related isothiocyanates on the antioxidant response element (ARE)-mediated antioxidant enzyme heme oxygenase-1 (HO-1) induction in human hepatoma HepG2-C8 cells were evaluated.
