Research Interests
Research in our lab seeks to understand the molecular and biochemical mechanisms that drive the pathological growth, remodeling, and cell death of the heart. A normal adult heart functions almost exclusively aerobically, as evidenced by the high density of mitochondria in heart cells (cardiomyocytes). The transcriptional and biochemical regulation of mitochondrial energy metabolism plays a pivotal role in the heart to meet the high energy demand. However, it remains elusive as of how the transcriptional and biochemical regulation may alter to adapt to the pathological stresses in patients under conditions such as hypertension, infarct, and diabetes. Cardiomyocytes stop replicating shortly after birth, which coincides with the kick off of the aerobic metabolism of the heart for energy provision. Therefore, the proliferation and differentiation of cardiomyocytes appear to relate to a differential metabolic programs in the heart at different stages of development and pathophysiology.
Our team determines how altered metabolic programming is involved in the pathological development of the heart by dissecting potential pathways in cultured cells and genetically engineered mice that are subjected to various disease conditions. We seek to gain mechanistic insights at the cell, organelle, organ, and intact animal level using techniques in physiology, histology, cell biology and biochemistry integrated with various omics analyses. We also apply insights from the heart to other tissues and look further into the systemic and inter-tissue cross-talks at other disease states. The long-term goal is to understand the complex interactions that modulate genetic and metabolic reprogramming in the diseased heart, and to apply this information to novel clinical diagnostics and therapeutic strategies.
Research projects:
1) Probing the novel regulatory mechanism of myocardial metabolism in obesity
2) Energetic state and metabolic remodeling in cardiac hypertrophy and failure (supported by NHLBI)
