Vitamin D and the nutritional environment in functions of intestinal stem cells: Implications for tumorigenesis and prevention

Sporadic colon cancer accounts for ∼80% of CRC, with high incidence in western societies strongly linked to dietary patterns. The only mouse model for sporadic CRC results from feeding mice a purified rodent western-style diet (NWD1), establishing mouse intake of several common nutrients that mimic for each its level consumed in western populations at higher risk for colon cancer (higher fat, lower vitamin D3, calcium, methyl donors and fiber)....
