Research Interest

Mammary Gland Development and Breast Cancer
The research objectives of the Rosen laboratory are to elucidate the mechanisms regulating the normal development of the mammary gland including the hormonal control of milk protein gene expression, and to determine how these regulatory mechanisms have deviated in breast cancer. His laboratory is studying the role of systemic hormones, specifically prolactin, glucocorticoids, estrogens and progestins, and local growth factors, including members of the Wnt, Fgf and IGF families, on these processes. The role of specific transcription factors and their dominant-negative isoforms, including members of the C/EBP, Stat and NF I families, are also being examined using transgenic and knockout mouse models. Postnatal mammary gland development is being studied in knockout mice displaying late embryonic or neonatal mortality by transplantation of mammary epithelium into the cleared mammary gland fat pad of syngeneic recipients. Genetically engineered mice, coupled with FACS analysis and transplantation into the cleared mammary fat pad, have also been employed as model system in which to isolate and characterize functional mammary stem/progenitor cells. Transgenic and knockout mouse models are being used to elucidate changes in normal mammary gland stem cells and progenitors and signal transduction pathways that are involved in the progression from the normal mammary gland to preneoplasias, as well as the role of mutant p53 and Chk1 in genomic instability and the development of aneuploidy. These studies are being translated into the clinic to understand the mechanisms of therapeutic resistance of cancer stem cells to chemotherapy and radiation. Finally, studies are underway to elucidate the mechanisms by which noncoding RNAs regulate mammary gland development and are altered in breast cancer.
