Our long-term goal is to dissect the role of CXC chemokine receptors in breast cancer stemness in metastatic triple-negative breast cancer (mTNBC).  Currently, we are interested in targeting many signaling nodes downstream of CXCR4 in combination with other vulnerable, actionable molecular targets in in vitro and preclinical orthotopic mouse models. We also work on PK/PD of the drug combinations and any attendant toxicities involved by testing them in immunocompetent mice and zebra fish.
