Dr. Gloria Su and her laboratory study the molecular genetics of head and neck squamous cell carcinoma (HNSCC) and pancreatic ductal adenocarcinoma, as well as mouse modeling needed for both cancer types. HNSCC and pancreatic ductal adenocarcinoma are both results of accumulated genetic alterations. Both cancer types share some common oncogenes and tumor-suppressor genes (e.g. p16 and p53), but each has its unique targeted mutations (e.g. Cyclin D1 for HNSCC and K-ras for pancreatic cancer). We continue to compare and contrast the molecular genetic profiles of these two cancer types using both broad genome-scanning approach and candidate-gene approach. By establishing the cancer genetic profiles, we hope to reveal new prognostic markers, discover tumor marker for early detection analysis, and develop chemopreventive and therapeutic treatments that target tumor-specific pathways.
Creating and analyzing mouse models that mirror human tumorigenesis is another one of the major focuses of my laboratory. Tissue-specific knock-out (conditional knock-out) mice based on the genetic profiles of human ductal pancreatic cancer and HNSCC are currently in progress in my laboratory.
