| Outline of Final Research Achievements |
Whole-leaf extract of "Kidachi aloe"(Aloe arborescens; Aloe) and its main ingredient aloin have been reported to exhibit anti-inflammatory and anti-tumor effects in some experimental models.
In the present study, we examined the cancer preventive effects of Aloe and aloin in an Apc-deficient Min mouse model. In the first experiment, Min mice were fed a basal diet or a diet containing low-dose Aloe for 12 weeks. Aloe significantly reduced the number of intestinal tumors. In a second experiment, we examined the effects of low-dose Aloe and aloin on intestinal tumor development in Min mice fed a high-fat diet for 11 weeks. Aloin, but not Aloe, significantly reduced the number of intestinal tumors. We also found that feeding with aloin increased plasma adiponectin levels in Min mice.
These results suggest that low-dose aloin has preventive effects against intestinal tumor development in Min mice fed high-fat diet, possibly, in part, by increasing adiponectin in blood.
