Research Interests –

We study signaling pathways activated by muscarinic acetylcholine receptor subtypes. In particular, we are interested in how interactions between integrins and extracellular matrix (ECM) proteins regulate these pathways.

Our second interest is the regulation of the discoidin domain receptor 1 (DDR1) by ECM proteins. DDR1 is a tyrosine kinase receptor for collagen that is often overexpressed in epithelial cell cancers. We wish to determine if differential responsiveness of DDR1 to collagen type IV (a component of the basement membrane) and collagen type I (a constituent of the stroma) plays a role in the development of breast cancer.

A third interest is the regulation of proteolytic processing of the amyloid precursor protein (APP) of Alzheimer’s disease (AD). APP proteolysis by beta- and gamma-secretases releases an amyloidogenic protein, Abeta, that forms insoluble deposits in the brain in AD. We are studying the mechanisms by which receptor-coupled signaling pathways activate another class of proteases, known as alpha-secretases, that cleave APP within the A domain, and preclude the formation of amyloid.
