Technical Abstract: Folate and other B-vitamins play important roles in DNA methylation, and adequate intakes of these nutrients have been implicated in the prevention of colon cancer. Concentrations of B-vitamins in the maternal diet may impact disease susceptibility in offspring. Therefore, we investigated the effect of maternal B-vitamin intake on intestinal tumorigenesis in offspring. Our data indicate that maternal B-vitamin supplementation suppresses tumorigenesis in Apc+/1638N offspring relative to deficient and replete maternal diets and furthermore that maternal B-vitamin depletion accelerates the acquisition of invasive characteristics in tumors.
