Research Description:

Our research focuses on extracellular regulatory proteins that control and orchestrate events as diverse as growth factor signaling and formation of the extracellular matrix (ECM).  Such events are critical in adult vertebrates (e.g. for maintenance of the cardiovascular system, wound healing, turnover of the skeleton and synaptic plasticity) and are even more dynamic during development. One class of these regulatory molecules comprises small families of proteases that activate and inactivate various growth factors, enzymes and extracellular structural macromolecules. Another class comprises antagonists of signaling by members of the TGFb superfamily of growth factors. Three additional classes of regulatory molecules under study modify actions of the first two by as yet unclear mechanisms. Molecules we study play central roles in morphogenetic processes and defects in these proteins may underlie human disease.  Our studies employ biochemical, genetic and developmental analyses, including characterizing standard and conditional “knockout” mice, and zebrafish and examining possible links between defects in genes of interest and human development and disease. Current studies include roles of extracellular proteins in adipocyte biology, pre-diabetic symptoms, atherosclerosis, and organ transplant rejection. The latter two studies include translational studies of human patients.
