Objective
Each year 1.1 million new cases of breast cancer will occur among women worldwide and 400,000 women will die from this disease. Although progress has been made in understanding breast tumor biology, most of the relevant molecules and pathways remain undefined. Their delineation is critical to a rational approach to breast cancer therapy. This proposal focuses on the role of the under-explored family of protein-tyrosine phosphatases (PTPs) in the normal and neoplastic breast. Virtually all cell signaling pathways are modulated by reversible protein tyrosine phosphorylation, which is regulated by two classes of enzymes: protein-tyrosine kinases (PTKs) and PTPs. Not surprisingly, tyrosine phosphorylation has an important role in breast development and cancer. Whereas the role of specific PTKs, like the HER2 receptor, in breast cancer is well studied, almost nothing is known about the function of specific PTPs in this disease. Our preliminary data suggest that PTP1B has an important role in breast differentiation and that both PTP1B and SHP2 play positive roles in breast cancer. The two predominant goals of this proposal are: First, to delineate the role of PTP1B and other PTPs in normal breast development and differentiation; second, to address the roles of PTP1B and other PTPs in the maintenance of breast cancer and metastasis and to assess their merits as drug targets. These studies not only use state-of-the-art ex vivo and in vivo models for studying breast pathophysiology, but also cross the boundaries between the developmental and cancer research fields and between basic science and clinical applications. Our research should ultimately lead to the rational design of targeted therapies that will improve the clinical management of patients with breast cancer.
