Cancer Metabolism and Stemness

Tumor heterogeneity is frequently displayed in human cancers and is known as a major contributor for drug resistance, tumor relapse and consequently cancer death. Currently, there are two mechanisms that contribute to tumor heterogeneity. One mechanism is that during tumorigenesis, various normal cell clones acquire genetic/epigenetic alterations, thus give rise to heterogeneous tumor cells.  Another mechanism that accounts for tumor heterogeneity is the existence of cancer stem cells (CSCs). Therefore, my research focus is to decipher regulatory machinery responsible for tumor heterogeneity and hope to develop therapeutic strategies accordingly by pursuing the following directions.

1)      To delineate the network of metabolic reprogramming in tumor initiation and progression. Glucose metabolism reprogramming is a newly engaged cancer hallmark. Recently, ample evidence including my recent finding (Chan et al. Cell 2012) has demonstrated that targeting glycolysis could overcome resistance to current therapies, such as chemotherapy and targeted therapy (Herceptin therapy). Hence, my laboratory is interested in deciphering regulatory network for glucose metabolism, which will reveal novel therapeutic targets beneficial for cancer treatment.

2)      To explore regulatory machinery orchestrating EMT-driven cancer stemness and drug resistance. The CSC population preferably stays in quiescence stage (G0 phase) and thus adversely sensitizes to chemo- or radio-therapies. Epithelial to mesenchymal transition (EMT) program is responsible for cancer progression, drug resistance and recently is engaged in acquiring CSC properties. Thus, my research is to decode regulatory network of EMT, which will identify new strategies to eliminate CSC population and overcome drug resistance.

3)      Development of small molecule inhibitors targeting glycolysis or EMT as new therapeutic interventions. Once novel targets for cancer prevention have been identified as described above, I will use in silico screening to develop novel therapeutic arsenals accordingly. This research program is expected to identify effective inhibitors that are anticipated to overcome drug resistance and prolong tumor remission through targeting glycolysis or EMT.
