The Wnt pathway controls cell fate during embryonic development. It also persists as a key
regulator of homeostasis in adult self-renewing tissues. In these tissues, mutational
deregulation of the Wnt cascade is closely associated with malignant transformation. The
intestinal epithelium represents the best-understood example for the closely linked roles of
Wnt signaling in homeostatic self-renewal and malignant transformation. In this review, we

The Wnt pathway controls cell fate during embryonic development. It also persists as a key regulator of homeostasis in adult self-renewing tissues. In these tissues, mutational deregulation of the Wnt cascade is closely associated with malignant transformation. The intestinal epithelium represents the best-understood example for the closely linked roles of Wnt signaling in homeostatic self-renewal and malignant transformation. In this review, we outline current understanding of the physiological role of Wnt signaling in intestinal biology. From this perspective, we then describe how mutational subversion of the Wnt cascade leads to colorectal cancer.
