Our research goal is to understand the molecular and cellular mechanisms that facilitate tumor cell invasion and metastasis. To invade tissue barriers (extracellular matrix), metastatic tumor cells activate migratory and invasion programs that turn on genes involved in cell adhesion and proteolysis. Our lab is focusing on unveiling the cross talk between the discoidin domain receptors (DDRs), a unique set of receptor tyrosine kinases (RTKs) that are specifically activated in response to collagen, and the matrix metalloproteinases (MMPs), a family of proteases known to degrade collagen. The focus of our research is to understand DDR signaling and function in breast and prostate cancer. In breast tissues, we are investigating the role of DDRs in normal mammary gland morphogenesis and function and in cancer development, specifically DDRs' role in the transition from in situ to invasive carcinoma. In prostate cancer, our focus is unveiling the contribution of DDRs to the survival of prostate cancer cells in the bone microenvironment, the major site of prostate cancer metastasis. We are also investigating how proteolysis of the collagen matrix by MMPs regulates DDR phosphorylation and signaling in normal and malignant cells. Our hypothesis is that a cross between MMP activity and DDR signaling contributes to tumor cell invasion and metastasis. To address this hypothesis, we utilize a comprehensive variety of biochemical, structural, and cellular approaches, animal models of cancer progression and knockout mice.
