Our work was the first to develop biomarkers for risk stratification of ductal carcinoma in situ, a pre-malignant lesion of breast cancer. Our recent work has identified molecular aspects of stromal-epithelial stress responses and the interactions that facilitate tumor progression in breast, prostate and other cancers. These analyses have enabled us to identify cell-extrinsic consequences of epithelial stress that lead to the activation of pro-tumorigenic stromal phenotypes. One of the most profound phenotypes involves the activation of a multicellular stromal program shared by high mammographic density and desmoplastic tumor tissues, characterized by repression of CD36. While studying these interactions we unexpectedly found a rare population of cells within disease-free tissue that has the potential to attain pluripotency. These cells have the ability to create functional tissues of all three germ layers which we hypothesize may be involved in metaplasia and inflammatory diseases. A single pluripotent cell can generate beating cardiomyocytes, lactating breast, bone, cartilage, vasculature, adipocytes, pancreas, and intestinal cells. We hypothesize that these cells may be the cell-of-origin for metaplastic cancers and provide insights for the identification of novel therapeutic targets. Similarly, these cells may be responsible for a wide collection of phenotypes that are initiated by chronic stress and defective in a wide spectrum of cancers. Our current studies, couched in a large multi-disciplinary, multi-investigator grant, are aimed at investigating the role of chronic inflammation in increased cancer incidence with the intent of developing preventive and therapeutic solutions.
