Tumour and immune cell metabolism. The metabolism within and outside of tumour cells is markedly different from that of normal cells in differentiated tissues. Metabolic reprogramming usually confers pro-proliferative and/or survival advantages to tumour cells. Emerging evidence suggest that metabolic alteration is ultimately linked to genetic changes that contribute to cell fate decisions. Currently, we are interested in how cancer cells rewire their metabolism, particularly the role of the most frequently mutated gene p53 in tumour cell metabolism. We are also interested in how nutrient alteration or changes in microenvironmental metabolites is sensed by cancer and immune cells, and how metabolic remodeling influences anti-tumour immune responses. Understanding these issues will have great value for defining and targeting a therapeutic window for treating cancer.
