ANTI-CSC COMBINATION THERAPY USING WNT SIGNALING-TARGETED DRUG
Dysfunctions of Wnt, Hedgehog and Notch pathways are evident in multiple tumor types and malignancies. A number of studies have suggested that dysregulation of Wnt/β-catenin signaling occurs in human breast cancer. Specifically, inhibition of Wnt/ β-catenin pathway is implicated in arresting of cancer stem cells (CSCs), a small subset of cancer cells capable of self-renewal and differentiation into heterogeneous tumor cells. Here, we investigated tumor initiating property of breast cancer stem cell in-vitro with XAV-939 an inhibitor of Wnt/β-catenin signaling pathway. Targeting Wnt/β-catenin signaling with this inhibitor represents a promising strategy to suppress metastasis.
