Breast cancer remains the second leading cause of cancer-related deaths among US women. Recent studies have established that breast cancer is not a single disease but rather a group of diseases, with at least three major subtypes of basal, luminal and ErbB2-positive cancers. The subtype of breast cancer determines the disease-free and overall survival among breast cancer patients. Thus, understanding the origin of various subtypes of breast cancers is directly linked to the therapeutic choices, and outcomes of disease. Our laboratory is focused on defining i) origin of breast cancer subtypes from progenitor/stem cells; ii) Identification of novel cellular proteins that determine breast cancer prognosis and patient survival, such as Ecdysoneless (ECD) and Alteration/Deficiency in Activation (ADA3). We identified these two novel proteins as major regulators of cell cycle progression and oncogenesis. Current focus of the laboratory is to define mechanisms and clinical relevance of these proteins and the associated complexes in breast and other solid cancers using cell biological, molecular biology, biochemistry, animal models and patients’ specimens.

Recent Research Highlights
- We have demonstrated a novel role of mammalian Ecdysoneless in cell cycle regulation.
- We have demonstrated that Ecdysoneless is overexpressed in breast cancers and overexpression of Ecdysoneless serves as a marker of poor prognosis in HER2/neu-overexpressing breast cancer patients.
- We have generated the first telomerase-immortalized human mammary stem/progenitor cells that maintain their ability to self renew and differentiate.
- We have demonstrated that ectopically-expressed oncogenes induce block in lineage specific differentiation of immortal human mammary stem / progenitor cells.
