Our lab focuses on understanding the basic mechanisms by which secreted growth factors regulate and coordinate cell signaling in complex multicellular organisms. Our specific interest centers on the essential human cell surface receptor neuropilin. Neuropilin is a conserved bi-functional mammalian cell surface receptor. Neuropilin has fundamental biomedical importance since it is essential to two distinct biological processes, angiogenesis and axon guidance. In additions to its normal roles, neuropilin also functions in tumor angiogenesis. Neuropilin expression is observed in tumor vasculature, and overexpression promotes tumorigenesis in vivo for a variety of solid tumors including those of the pituitary, prostate, breast, and colon. Strategies to inhibit neuropilin activity are being developed as potential antitumor therapies. Our lab seeks to define and improve mechanisms of inhibiting the neuropilin signaling pathway.
