The goal of our research is to study the molecular and cellular mechanisms of human ductal carcinoma in situ (DCIS) progression to invasive breast cancer (IBC). We have established active collaborations with the Breast Cancer Prevention group at KUMC and KU-Wichita for obtaining primary human DCIS biopsy and surgical samples. Our collaboration with KU clinicians has allowed development of the first human DCIS xenograft model by intraductal injection of primary DCIS cells obtained from patient samples. This model that we refer to as MIND (mouse-intraductal) closely mimics human DCIS and allows the study of epithelial/stromal interactions that orchestrate the process of DCIS to IBC transition. The active projects in the lab include the effects of hormonal stimulation on cancer stem cell self-renewal and transition to invasiveness and the role of MicroRNAs in DCIS to IBC transition.
