Principal Research Support Specialist

Mrs. Liqun Huang graduated valedictorian from Wuhan University, one of the top universities in China. She has been working in various areas of pharmacology, molecular biology and microbiology. She has extensive experience with preclinical animal models of cancer, small animal surgery, pharmacology as well as cell culture, Western blot, ELISA and immunohistochemistry.

Over the years, Mrs. Huang has played an important role in the evaluation of novel anti-cancer and anti-inflammatory compounds as evidenced by several first-author publications in leading journals.

She has been a key contributor to this published work with technical excellence.

4. Co-developed a novel inhibitor of NF-κB activation:

Mrs. Huang was part of a team of four that developed a novel small molecule inhibitor of NF-κB based on our observation that annexin 1 is an endogenous inhibitor of NF-κB and that annexin 1 mediates the anti-inflammatory activity of all corticosteroids. This peptide is currently being developed for clinical applications.

5. Screening for cooperating oncogenes in leukemia:

Mrs. Huang’s early research at the National University of Singapore focused on screening for oncogenes in RUNX1+/-transgenic mice. She was involved in identifying cancer genes cooperated with the RUNX1 gene in acute myeloid leukemia (AML) by retroviral integration. The selected four publications below summarize the main points of the work.
