How I am inventing the future of medicine
I seek to identify and target key players in cell metabolism and mitochondrial function to engineer cells more resistance to environmental stresses.
Research Interests
Energy metabolism in cardiovascular diseases
Mitochondrial function and metabolic signaling
NMR spectroscopy and Imaging-guided spectroscopy
Research Description
Our laboratory is interested in identifying and targeting the key regulators of cell metabolism and mitochondrial function for the treatment of cardiovascular and metabolic diseases. To achieve our goals we perturb the metabolic network by altering its key element using bioengineered mice and determine the metabolic and functional outcomes using multi-nuclear NMR spectroscopy, MRI-guided metabolic imaging and mass spectrometry. We also test the effects of metabolic intervention in a wide range of therapeutic strategies including preventive and regenerative medicine. One focus of our research is on the dual role of mitochondria as a power plant (ATP production) and a death engine (triggers of necrosis and apoptosis). We seek to identify nodal points for promoting mitochondria-based cardioprotection and stem cell differentiation. Our effort in this direction includes mitochondrial biogenesis, redox regulation and protein (de)acetylation. The second focus of our work is on substrate metabolism and metabolic signaling that involve lipids, sugar and amino acid metabolism. This line of research seeks to optimize cell metabolism in response to stresses via bioengineering approaches. We are particularly interested in the AMPK signaling cascade, a cellular energy sensor and a master regulator of cell metabolism and survival. We are searching for novel targets of AMPK in the heart utilizing gain-of-function and loss-of function approaches in both cellular and whole animal models.
