Suppressive effect of Siraitia grosvenorii extract on dicyclanil-promoted hepatocellular proliferative lesions in male mice

Dicyclanil (DC) generates reactive oxygen species (ROS) due to Cyplal induction, and DNA damage caused by oxidative stress is probably involved in hepatocarcinogenesis in mice. To clarify the modifying effect of the Siraitia grosvenorii extract (SGE), which has antioxidative properties, we employed a 2-stage liver carcinogenesis model in partially hepatectomized male ICR mice. Mice maintained on diet containing DC at a concentration of 1,500ppm for 9 weeks after a single intraperitoneal injection of diethylnitrosamine (DEN) at a dose of 30mg/kg and they were given water containing 2,500ppm of SGE for 11 weeks including 2 weeks as pre-administration on DC. SGE inhibited the induction of γ-glutamyltranspeptidase-positive hepatocytes, lipid peroxidation, and gene expression of Cyplal, all of which were caused by DC. To examine whether SGE indirectly inhibits Cyplal expression induced by inhibition of aryl hydrocarbon receptor (Ahr)-mediated signal transduction caused by DC, mice with high (C57BL/6J mice) and low affinities (DBA/2J mice) to Ahr were given DC-containing diet and/or SGE-containing tap water for 2 weeks. Cyplal gene expression was significantly lower in C57BL/6J mice administered DC+SGE than in C57BL/6J mice administered DC alone; there was no difference in the Cyplal expression between DBA/2J mice administered DC+SGE and DC alone. These results suggest that SGE suppresses the induction of Cyplal, leading to inhibition of ROS generation and consequently inhibited hepatocarcinogenesis, probably due to suppression of Ahr activity.
