Abstract:

Canonical Wnt/β-catenin signaling pathway is of great significance to the occurrence and progression of tumors which make it an exciting target in cancer therapy. The pathway is also required in regeneration of normal tissues, so the specificity of inhibitors targeting this pathway may be affected. The coactivator of β-catenin, B cell lymphoma 9 (BCL9), is highly expressed merely in tumor cells. Accordingly, inhibitors targeting the interaction between β-catenin and BCL9 may demonstrate robust specificity and minimal toxicity. BCL9 increases tumor growth, invasion and metastasis by promoting epithelial-mesenchymal transition, up-regulating vascular endothelial growth factor and CD44 expression and regulating cancer stem cell traits. BCL9 promises to be a new target for cancer therapy.
