Research Focus


Our research focuses on two areas:

1) Dysregulated ubiquitin modification & cancer

Ubiquitin modification of cellular proteins plays a vital role in maintaining the balance between normal cell growth and uncontrolled cell proliferation. Accordingly, dysregulation of the ubiquitination process has been shown to contribute to oncogenesis. we are currently employing acombination of biochemistry, cell biology, and genetic approaches to investigate the roles of the ubiquitination machinery in carcinogenesis, cancer progression, and anti-cancer drug resistance.


2) Chinese herbal medicine (CHM) against cancer

Compared to modern western drugs, CHM offers a brighter perspective in treating complex diseases such as cancer, owing to its “multi-active component, multi-drug target, and multi-function” characteristics. However, understanding the scientific basis of CHM against cancer at the molecular level and in a systematic manner is still one of the great challenges in CHM research. We are currently exploring a novel strategy on CHM study by integrative exploiting of network pharmacology, bioinformatics, pharmacokinetics, biochemistry, cell biology, and genetic approaches, aiming to translate CHM from an “experience-based medicine” into a modern “evidence-based medicine”.
