Runx1 is a tumor suppressor gene in the mouse gastrointestinal tract

ABSTRACT: The Runx1 transcription factor plays an important role in tissue homeostasis through its effects on stem/progenitor cell populations and differentiation. The effect of Runx1 on epithelial differentiation of the secretory cell lineage of the colon was recently demonstrated. This study aimed to examine the role of Runx1 in tumor development in epithelial cells of the gastrointestinal tract. Conditional knockout mice were generated that lacked Runx1 expression in epithelial cells of the GI tract. These mice were crossed onto the ApcMin background, sacrificed, and their intestinal tumor phenotypes were compared with ApcMin Runx1 wildtype control mice. Apc-wildtype Runx1-mutant mice were also examined for tumor development. Colons from Runx1 knockout and wildtype mice were used for genome-wide
