The primary goal of our laboratory is to identify novel pathways that control fibroproliferation with the goal of developing therapeutic inhibitors. Fibroproliferative responses are similar to wound healing processes involving accumulation of contractile myofibroblasts and extracellular matrix (ECM) secretion. Because organ fibrosis, cardiovascular, metabolic/obesity, and cancer pathologies are now recognized to be impacted by fibroblast-myofibroblast differentiation and ECM remodeling our research is examining novel pathways and control mechanisms in these diseases. Central to our studies is determining the function of Aortic carboxypeptidase-like Protein (ACLP), a secreted, collagen-binding protein that enhances fibrosis and myofibroblast differentiation through mechanisms that involve stimulating the transforming growth factor ß (TGFß) receptor signaling complex and controlling mechanical signaling and ECM remodeling.
Active projects in the lab include:
1. Defining the pathways that control vascular adventitial remodeling
2. Inhibiting organ fibrosis through targeting ACLP
3. Developing systems to understand the stomal reaction in breast cancer (in collaboration with the Kirsch lab).
4. Uncovering new mechanisms that control adipose tissue fibrosis (collaboration with Farmer lab).
