| 内容記述 | In order to characterize the biological actions of zerumbone (ZER), a cancer-suppressive component from rhizomes of Zingiber zerumbet Smith, its effects on the activities of various xenobiotic-metabolizing enzymes were analyzed. Mice were treated orally with ZER (10-100 mg/kg, once a day for 4 successive days) and then the enzyme activities in mouse organs were examined. Within the liver ZER increased glutathione S-transferase (GST) and quinone reductase (QR) activities in a dose-dependent manner up to 204% and 168% of the control, respectively. As the GST activation was most apparent with 1,2-dichloro-4- nitrobenzene as substrate, ZER seems to mainly induce the activity of class μ GST, which was supported by the result of a Western blotting experiment. In addition, contents of glutathione (reduced form) were slightly higher in the ZER-treated liver. Similarly, small intestine GST and QR activities elevated to 861% and 256% of the control, respectively, upon ZER treatment. In contrast, the activities of those enzymes fl uctuated little in kidney, lung or brain of ZER-treated mice. As for the phase I enzymes in the liver including cytochrome P450 and cytochrome b5; activities of 7-ethoxycoumarin O-deethylase, 7-methoxyresorufi n O-demethylase, 7-ethoxyresorufi n O-deethylase and 7-pentoxyresorufi n O-depentylase , ZER caused only marginal changes. Our study clearly indicated that ZER selectively activates phase II enzymes in the liver and small intestine, and thus can be considered to be a promising nutraceutical for cancer chemoprevention. |
