The focus of my research is the role of reactive oxygen species (ROS) in mediating cartilage degradation in osteoarthritis (OA). More specifically, I am studying the a5ß1 integrin intracellular signaling pathway in chondrocytes that results in an upregulation of matrix metalloproteinases (MMPs), or cartilage ECM degrading enzymes, when stimulated. We have recently shown that endogenous ROS are required for a5ß1 integrin stimulated MMP production. Currently, I am working to identify the redox sensitive signaling protein in this pathway that is oxidized directly by ROS and the mechanism by which this occurs. This investigation will help to clarify the molecular basis of OA development.
