Abstract : The goal of this research project is to explore the role of TGF-B receptors in mammary tumorigenesis and to define the relationship between estrogen receptor and TGF-B receptor signal transduction pathways. We have pursued three approaches in addressing this question: (1) reintroduction 0 - the type II TGF-B receptor into MCF-7 cells resulting in reduced tumorigeicity, (2)characterization of the role p15 and p2i, two CdkI's,play in TG -B diated signal transduction and (3) the involvement of dwarfins in the signaling cascade downstream of the TGF-B receptors. Further analysis of - the inhibitors and dwarfins will not only contribute to our understanding breast tumorigenesis, but may reveal potential targets for therapeutic intervention.
