School of Science
From botany to agricultural science, further in ethnopharmacology and now cancer cell biology, Dr Lee Wai Leng explored a great spectrum of biological studies in her professional development. Her current research focus on the study of cancer-derived exosomes. Among a variety of cell-derived vesicles, exosomes are the nanovesicles released from various cell types into the extracellular space for intercellular communication. These vesicles were reported to serve as vehicles for intercellular transfer of genetic material (mRNA, miRNA) or proteins. Lately, these vesicles were found to play significant role in cancer development. My research interests include:
- To study the role of exosome in cancer progression
- To investigate the link between oncogenic mutation and exosome-mediated carcinogenesis
- To explore exosome as a novel source of non-invasive cancer biomarkers given that the cancer-specific molecules were identified in the exosomes isolated from biological fluids such as urine, saliva, blood and breast milk.
On the other hand, concerns about drug resistance and side effects of currently used therapeutic agents have raised interest in phytochemicals derived from dietary foods and traditional medicines which allow safe and continuing ingestion. Therefore Dr Lee's research also aims to discover the therapeutic use of local medicinal plant-derived phytochemicals in cancer treatment.

- Discovery of novel targetable pathways in cancer treatments - Several novel signaling pathways in breast cancer were discovered in my previous study. Among the components involved in these pathways, exosome is an extremely intriguing target in cancer treatment. Currently, one of the research projects in my laboratory aims to investigate the links between oncogenic mutation and exosome-mediated carcinogenesis.
- Development of novel treatment options involve phytochemicals to provide breakthrough in treating life-threatening cancer diseases - Concerns about drug resistance and side effects of currently used therapeutic agents have raised interest in phytochemicals derived from dietary foods and traditional medicines which allow safe and continuing ingestion. Therefore my research also aims to discover the therapeutic use of local medicinal plant-derived phytochemicals in cancer treatment.
