TGF-β has been named the molecular Jekyll and Hyde of cancer due to its ability to both suppress and promote tumor development. Components of the TGF-β signaling pathway are often mutated in cancer to inhibit the tumor suppressor roles of TGF-β. Our lab studies how a 3-alanine deletion in the...
In the process of development of a multicellular organism, cells must make stable, binary fate decisions in response to intercellular signaling. A critical question is how weak or transient activation of signaling pathways achieves a robust and long-term switch in gene expression, and thus determines cell fate. I report that...
