What is another cancer type in which mutations in the Wnt pathway play a prominent role?

The role of Wnt signaling in carcinogenesis has most prominently been described for colorectal cancer, but aberrant Wnt signaling is observed in many more cancer entities.

What does the TCF4 gene do?

The TCF4 gene provides instructions for making a protein that attaches (binds) to specific regions of DNA and helps control the activity of many other genes. On the basis of this action, the TCF4 protein is known as a transcription factor. The TCF4 protein is part of a group of proteins known as E-proteins.

Is Wnt good or bad?

As a central pathway in both development and homeostasis, the Wnt pathway regulates cell growth, survival and movement, and uncontrolled activation of this pathway can result in neoplasia and cancer.

What type of signaling is Wnt?

The Wnt signaling pathways are a group of signal transduction pathways which begin with proteins that pass signals into a cell through cell surface receptors. The name Wnt is a portmanteau created from the names Wingless and Int-1.

Where is the TCF4 gene located?

Transcription factor 4 (TCF-4) also known as immunoglobulin transcription factor 2 (ITF-2) is a protein that in humans is encoded by the TCF4 gene located on chromosome 18q21.2.

What activates Wnt Signalling?

Wnt signaling begins when a Wnt protein binds to the N-terminal extra-cellular cysteine-rich domain of a Frizzled (Fz) family receptor. These receptors span the plasma membrane seven times and constitute a distinct family of G-protein coupled receptors (GPCRs).

Is Wnt a morphogen?

Morphogens are diffusible signalling molecules that pattern cellular fields by setting up differential gene expression in a concentration-dependent manner. Members of the Wnt family of signalling molecules are generally considered to be classical morphogens.
