Anna Chi Man TSANG (曾智敏)

B.Sc., Ph.D (HKU)annatsang@cuhk.edu.hk

Dr Tsang joined the Department of Anatomical and Cellular Pathology from October 2018. She received her Bachelor and Master of Philosophy degrees in the Chinese University of Hong Kong (CUHK). She obtained her PhD and postdoctoral training in the University of Hong Kong (HKU), and was then employed as Research Assistant Professor in the School of Biomedical Sciences. In 2011, she got the Young Investigator Award in the 18th Hong Kong International Congress of Cancer. With the award of the University of Hong Kong/China Medical Board Grant in 2013, she was appointed as a visiting scholar to examine live-cell invasion processes using advanced optical microscopies in King’s College London, UK. Her research interests are mainly on the roles of Epstein-Barr virus (EBV) in the pathogenesis and progression of nasopharyngeal carcinoma (NPC). She has established several premalignant cell lines from tumor-adjacent nasopharyngeal tissues from NPC patients to study the effects of latent EBV genes in the carcinogenesis of NPC. One of her studies has also defined the requisite genetic alterations which permit the viral latency establishment for NPC development. From 2018, she has also been appointed as a Honorary Assistant Professor in the School of Biomedical Sciences in HKU. Her recent researches focus on (i) developing innovative mRNA-based and aptamer-based therapeutic strategies to target EBV-associated NPC, (ii) utilizing organoid and patent-derived xenograft systems for preclinical drug testing, (iii) building up humanized mice platform for assessing the immune evasion properties of NPC cells in related to genetic depositions and EBV infection, and (iv) performing 2D and 3D live-cell imaging to examine cancer cell invasion into matrix.

 

Research Interests:

(a) Investigating the molecular roles of Epstein-Barr virus (EBV) infection in the development of nasopharyngeal carcinoma (NPC),
(b) Preclinical assessment of translational strategies to NPC using 3D organoid culture, patient-derived xenograft model and humanized mice model,
(c) Discovery of aptamers for visualizing and targeting of NPC tumors,
(d) Establishing advance live-cell imaging and intra-vital animal imaging for examining invasive properties of NPC cells,
(e) Applying micro-fluidics and bio-engineering platforms to study the migration behaviors of NPC cells in a bio-mimetic tumor microenvironment.
