Research Interests
My laboratory is focusing on deciphering the molecular mechanisms involved in human breast cancer initiation, progression and metastasis, as well as chemoresistance. Based on the mechanisms identified, we will then develop novel therapeutic strategies to overcome these clinical challenges with an eventual goal of curing malignant breast cancer.
Two major projects are currently ongoing in the laboratory.
1. Transcriptional regulation of novel metastasis driving genes in TNBC. Using global profiling technologies, including genomics, proteomics and metabolomics, we identify new molecular signatures in EMT program and cancer stem cells. We are now investigating the functional roles of the EMT promoting transcription factors in breast cancer metastasis and chemoresistance using integrative genetic, epigenetic approach as well as animal models and clinical specimens. We are specifically interested in discovering novel molecular mechanisms of transcriptional regulation of these EMT driving genes. These mechanisms include recruiting epigenetic modulators for transcriptional activation and interaction with spliceosome to facilitate RNA splicing.
2. Molecular characterization of metastasis driving proteins in metabolic reprogramming in TNBC cells. There is increasing evidence that mitochondrial dysfunction and metabolic reprogramming are closely associated with modulation of cell cycle and cell differentiation, which promotes cancer progression to a metastatic phenotype. However, there have been few studies linking pro-metastatic genes to impaired mitochondrial function and metabolic reprogramming. We demonstrate that a novel metastasis driving protein EGFL9 can not only regulates cMET signaling pathway, but also translocates to the mitochondria and drives a metabolic switch from oxidative phosphorylation to glycolysis. We are now clarifying this protein in TNBC and studying the detailed mechanism of EGFL9 in regulating metabolism in TNBC cells using LC-MS/MS based targeted metabolomics. The effect of these metabolites regulated by EGFL9 on cancer cells or tumor microenvironment will be further analyzed.
