Evaluating Dietary Compounds in Pancreatic Cancer Modeling Systems

With the establishment of outstanding rodent models of pancreatic neoplasia and cancer, there are now systems available for evaluating the role diet, dietary supplements, and/or therapeutic compounds (which can be delivered in the diet) play in disease suppression. Several outstanding reports, which demonstrate clear inhibition or regression of pancreatic tumors following dietary manipulations, represent a noticeable advancement in the field by allowing for the contribution of diet and natural and synthetic compounds to be identified. The real goal is to provide support for translational components that will provide true chemoprevention to individuals at higher risk for developing pancreatic cancer. In addition, administration of molecules with proven efficacy in an in vivo system will screen likely candidates for future clinical trials. Despite this growing enthusiasm, it is important to note that the mere one-to-one translation of findings in rodent models to clinical outcomes is highly unlikely. Thus, careful consideration must be made to correlate findings in rodents with those in human cells with full disclosure of the subtle but often critical differences between animal models and humans. Additional concern should also be placed on the approaches employed to establish dietary components with real potential in the clinic.
