要点:
- Identifying effective cancer chemopreventive agents will significantly reduce cancer morbidity and mortality, especially in high-risk individuals.
- Genetically engineered mouse (GEM) models of cancer must be assessed carefully for their relevance to human disease and for their predictive power for determining a cancer-prevention response in humans.
- Relatively fast and inexpensive testing of selected compounds can be performed using appropriate mouse models.
- Stage-specific responses to chemopreventive agents can be determined using GEM models, unlike TUMOUR XENOGRAFT models.
- Combination therapies targeting multiple oncogenic pathways can be performed readily in mouse models.
- GEM colon cancer models can be used to study the effects of chemopreventive agents on tumours arising from genetic lesions that are associated with multi-step carcinogenesis.
- Mammary cancer mouse models have demonstrated that certain preventive agents might prevent the transition from pre-invasive to invasive carcinoma.
- Nutritional supplements that target different molecular pathways are effective in a prostate cancer model.
- The ultimate goal remains the establishment of improved models that can be used for the predictive testing of preventive responses in humans.

英文摘要:
Sophisticated genetic technologies have led to the development of mouse models of human cancers that recapitulate important features of human oncogenesis. Many of these genetically engineered mouse models promise to be very relevant and relatively rapid systems for determining the efficacy of chemopreventive agents and their mechanisms of action. The validation of such models for chemoprevention will help the selection of appropriate agents for large-scale clinical trials and allow the testing of combination therapies.
