Research Currently in Progress

Head and neck cancer (HNSCC) is the sixth most prevalent cancer worldwide, affecting more than 250,000 people in the United States alone.  The incidence of HNSCC has increased dramatically in recent years.  The 5 year survival rate of 50% in HNSCC remains poor. My research studies the roles of the newly identified C53/RCAD protein complex in normal animal development and cancers.  The C53/RCAD protein complex has been recently shown to function as a pivotal regulator of multiple cell signaling pathways, including the DNA damage response, NF-kB signaling and cell cycle progression.  Its role in tumorigenesis and metastasis has also been investigated in head and neck carcinomas. We use various techniques including knockout mice, gene profiling and proteomics. Our findings may facilitate the development of a novel diagnostic biomarker and therapeutic target for cancer treatment.
In recent 5 years, worked in Dr. Crowe lab, my studies extend to cancer stem cells and telomere research.  Extensive telomere dysfunction is associated with aggressive HNSCC phenotypes such as metastasis and increased radioresistance.  High levels of telomerase activity correlate with advanced clinical stage, recurrent disease, and decreased overall survival.  Using a variety of transgenic models and patient tumor tissues, our laboratory is engaged in understanding how stem cells regulate their telomere length and how disrupted telomere maintenance can lead to tumor formation and metastasis.
