The long term goal of this research program is to understand the molecular basis of cellular machinery and their relationships to human diseases. A branch of the laboratory focuses on elucidating the interplays between transcription factors and signaling pathways. We ask how does extracellular stimuli communicate with intracellular effectors, and eventually modulate cellular responses in normal and diseased states. For example, we have recently demonstrated that adipokine gene expression mediated by transcription factor NFAT contributes to insulin and glucose homeostasis via a non-cell autonomous mechanism. We have further found that upstream regulators and downstream effectors of the NFAT transcription factor impinge on adipocyte biology at multiple levels, including novel crosstalk with G-protein coupled/cAMP signal trasduction via phospho-dependent protein degradation.
Another branch of the laboratory examines intercellular trafficking and its role in demyelinating neuropathy. A range of biochemistry, molecular biology and cell biology are applied, in conjunction with primary cell culture and engineered mice, to dissect the molecular basis of cellular machinery. In sum, I strongly believe elucidating the basis of molecular pathways will provide the most benefits in understanding human diseases.
