Research Interests

My research activities are focusing on revealing signaling pathways that activate NF-kB family of transcription factors. NF-kB is a family of transcription factors that play critical roles in inflammatory, anti-apoptotic, and immune responses. Revealing of various signaling pathways that lead to activation of NF-kB will provide molecular insight for developing therapeutic agents to treat cancer, autoimmune diseases, and inflammation. The major research in my lab is to determine the molecular mechanism by which NF-kB is activated by epidermal growth factor receptor (EGFR) family members. We have recently discovered a new signaling pathway, in which CARMA3 and Bcl10, two caspase-recruitment domanin (CARD)-containing adaptor/scaffold proteins, mediate EGFR-induced NF-kB activation and contribute to tumor progression and metastasis. We are currently investigating the mechanism by which CARMA3 is linked to EGFR signaling and its contribution to the malignancy of various cancers. The second research area in my lab is to determine the molecular mechanisms by which NF-kB is activated by antigen receptors. Antigen receptors play a critical role in the regulation of immune responses. Dysregulation of antigen receptor pathways results in leukemia, autoimmune, and immunodeficiency. Therefore, we are also studying the role of antigen receptor-induced NF-kB and other transcription factors in lymphocyte malignancy. The third research area in my lab is to determine the mechanism by which C-type lectin receptors activate NF-kB and other signaling and the role of C-type lectin receptors in innate immune responses.
