The effects of esculin, a natural coumarin compound, on the formation of 8-oxo-2'-deoxyguanosine (8-oxodG) and carcinogenesis induced by a chemical carcinogen, N-nitrosobis(2-oxopropyl)amine (BOP), were examined in the pancreas of female Syrian golden hamsters. Animals were given a diet containing esculin for 7 days, and killed 4~h after BOP treatment, and the contents of 8-oxodG were measured in the nuclear DNA of the pancreas. Esculin suppressed significantly the increase in the 8-oxodG content of hamster pancreas induced by BOP. Furthermore, the effect of esculin on the rapid production model experiment for pancreatic carcinogenesis using BOP was investigated. Esculin was given ad libitum as a 0.05% aqueous solution during either the initiation or promotion phases. The incidence of invasive tumors in animals given esculin during the initiation phase was significantly lower than in the control group, while the incidence in animals given esculin during the promotion phase showed no significant change. These results suggest that the intake of esculin has an inhibitory effect on BOP-induced oxidative DNA damage and carcinogenesis in hamster pancreas. |
