| Outline of Final Research Achievements |
We investigated the molecular mechanism of anticancer activities of phytochemicals against different subtypes of human breast cancer cells, and examined whether certain phytochemicals can be used as a preventive measure against breast cancer using rat model of EMS-induced mammary carcinoma. Phytochemicals used were isoflavones, curcumin, lycopene, nobiletin, and resveratrol. Although the molecular mechanism varies depending phytochemicals, they excerted anticancer activity by affecting intracellular signaling proteins associated with proliferation and apoptosis. In animal model, isoflavones and lycopene has been found to inhibit breast cancer development. Phytochemicals would be thus considered not only be effective in the primary prevention of breast cancer, but also be active in inhibiting the growth and progression of breast cancer.
