We are interested in the transcriptional regulation of matrix metalloproteinases (MMP) and tissue inhibitor of metalloproteinases (TIMP), MMP activation mechanisms, substrate specificity and interaction with the plasmin system. We are also interested in identifying transcriptional and post transcriptional mechanisms that alter the equilibrium between MMPs and their specific tissue inhibitors.
Our main aim is to further understand the complexities involved in the regulation of MMP and TIMP expression during tumor progression, to identify MMPs that may promote or protect against tumor invasion, how MMPs interact with the plasmin system to regulate tumor invasion and angiogenesis and which mechanisms are employed by tumors to alter the MMP/TIMP equilibrium. Our studies are of particular relevance to human neuroblastoma and breast cancer.
