Many of the signaling pathways that are involved in development are also involved in the onset and progression of disease. As an example, the Wnt signaling pathway is required during many stages of development and in the homeostasis of stem cells in the adult. Perturbation of this pathway in stem cells in the adult often leads to cancer. It is now known that greater than 90% of colorectal cancers are caused by mutations in the Wnt signaling pathway. As this pathway is important for both proper development and disease, I am curious to know how this pathway can turn it self on and off so many times during development and why it fails to turn off in disease. The lab focuses on two negative feedback regulators of Wnt signaling: Nkd1 and Axin2.
