Research Interests

Our current research focuses on fusion transcription factor family of proteins that result from chromosomal translocation and their role in cancer development. The working model understudy is Rhabdomyosarcomas (RMS). RMS tumors are the most common soft-tissue sarcoma of childhood cancer. RMS tumors are a heterogeneous group of malignant skeletal muscle tumors with alveolar RMS (aRMS) as the most aggressive. Greater than 85% of aRMS is characterized by either one of the two unique chromosomal translocations, t(2;13)(q35;q14) and t(1;13)(q36;q14) resulting in the formation of PAX3-FKHR and PAX7-FKHR fusion transcription factors, respectively. The fusion proteins gain functions not shared by the normal gene counterparts and these fusion protein-specific activities are crucial for the tumorogenic behavior by impacting the control of cell growth/differentiation, apoptosis, and motility. While the two fusion proteins share strong similarity in structural organization, there are significant clinical differences between tumors associated with their expression, indicating a distinction between the biological activities of the two proteins. Our approach to address these research aims involve a combination of biochemical and genetic analysis in tumor-derived cell lines, engineered mammalian cell culture systems, and animal models. We expect that these molecular data will provide insights into defects that are uniquely associated with RMS development as well as defects that are shared by other tumor classes. Ultimately, such understanding will enable us to improve the process of patient diagnosis/or prognosis and to refine the design of therapeutic reagents that specifically interrupt tumor function without damaging normal cell function.
