The Apcmin/+ mouse provides an excellent experimental model for studying genetic, environmental, and therapeutic aspects of intestinal neoplasia in humans. In this chapter, we will describe techniques for studying colon cancer development in Apcmin/+ mice on C57BL/6J (B6) background, focusing on the roles of environmental modifiers, including Dextran Sulfate Sodium (DSS), high fat diet, and bile acid supplementation in the context of experimental colorectal cancer. This chapter also includes protocols describing extraction and purification of DSS-contaminated RNA, as well as sampling, harvesting, and tissue processing. The common pathologic lesions encountered in these animals are described in detail.
