Research interests:


Tumor angiogenesis, anti-angiogenic proteins and cancer therapeutics:
Angiogenesis (new blood vessel formation) is essential for tumor growth and metastasis.  Anti-angiogenesis is a promising anticancer therapeutic approach.  We focus on investigating novel endogenous angiogenesis inhibitor proteins that contain the thrombospondin type 1 repeat domain (TSR) and their function and development into anti-angiogenic cancer drugs. These proteins are not only valuable for anticancer drug development, but also important for maintaining angiogenesis homeostasis in normal tissues. We have identified 3 novel endogenous anti-angiogenic proteins: Isthmin, ADAMTS5 and ADAMTS4. We are currently investigating their pathophysiological function and therapeutic applications. In addition, we are studying tumor endothelial cell biology and developing targeted drug delivery for liver cancer using tumor endothelial cell surface markers.

Angiogenesis and liver organogenesis in zebrafish model:
Angiogenesis is very important for cardiovascular biology and medicine. It is essential for all tissue formation and growth.  We use zebrafish as a model organism to study angiogenesis and liver development. Genes of interest include Augmenter of Liver Regeneration (ALR), Hepatocyte Growth Factor (HGF) and histone deacetylases (HDACs).
