62PTargeting Wnt pathway reduces primary tumor and metastasis in breast cancer models

Background: Biomarkers CD44 and CD24 are routinely used to identify breast cancer stem cells (BCSCs). BCSCs are chemotherapy resistant and bear high tumorigenesis and metastatic capabilities. Wnt/β-catenin signaling is involved in maintaining CSCs and thus is responsible for recurrence and poor prognosis. Role of Wnt receptor LRP6 in breast cancer promotion and progression is well known. We hypothesized that interactions between cancer cells, macrophages, and endothelial cells induce cancer stemness via activation of Wnt/-β catenin pathway, and blocking that pathway will reduce primary and metastatic tumors.
