My laboratory studies the cancer biology of Signal Transducer and Activator of Transcription 3 (STAT3) oncogenic pathway and STAT1 tumor suppressor in human cancers. Constitutive activation of STAT3 is frequently detected in most types of human cancers. We are studying the activation of STAT3 by upstream tyrosine kinases, HGF and SDF-1 and how they may function in STAT3-mediated cell survival, proliferation, tumor angiogenesis, and tumor cells/stroma fibroblasts interaction in cancer cells. The laboratory is also developing novel structure-based design of small molecule compounds that selectively target STAT3 oncogenic pathway in cancer cells as a new cancer therapeutic approach. Further, we are examining the interaction between STAT1 and p53 tumor suppressor and how they cooperate to mediate tumor suppression in cancer cells.
