Accumulating evidence indicates that hyperactive Wnt signalling occurs in association with the development and progression of human breast cancer. As a consequence of engaging the canonical Wnt pathway, a β-catenin–T-cell factor (TCF) transcriptional complex is generated, which has been postulated to trigger the epithelial–mesenchymal transition (EMT) that characterizes the tissue-invasive phenotype.
