Beta-Catenin: A Potential Survival Marker of Breast Cancer Stem cells
Abstract
The Wnt/beta-catenin pathway has been extensively studied for its role in development and cancer. The canonical Wnt signal is transduced by beta-catenin, which acts as a transcriptional coactivator by associating with the Tcf/LEF family of transcription factors. It has been established that Wnt signaling regulates the self-renewal of norma! stem cells in both the hematopoietic systems and the epidermis. In addition, constitutive activation of the Wnt pathway has been implicated in a number of epithelial cancers, possibly by promoting stem cell survival. However, the importance of this pathway in breast stem/progenitor cells has not yet been The central hypothesis of this study is that the Wnt/beta-catenin pathway plays a critical role in mammary gland stem cell survival, and as a result promotes tumorigenesis and resistance to conventional therapies.
