Profile Introduction

Our research focuses on the molecular and cellular mechanisms of cardiac arrhythmias using combined experimental and computational approaches. One of the long-term goals is to identify novel therapeutic strategies for treatment of cardiac arrhythmias. The laboratory has identified some atrial-specific ion channels and the regulatory mechanisms of these channels in atria and pacemaking cells and has begun to develop novel therapeutics for treatment of atrial arrhythmias.

Research Interests

Our laboratory has focused our research efforts in two major areas in cardiovascular diseases. 1. The study of the functional roles of different isoforms of cardiac calcium and calcium-activated potassium channels using combined techniques of transgenic mouse models, gene silencing and patch-clamp recordings. We utilize multiple approaches to determine the functional significance of the interacting partners of Ca and K channels in atrial myocytes and in so doing, provide new insights into the underlying mechanisms of certain forms of atrial arrhythmias. 2. Roles of soluble epoxide hydrolase (sEH) inhibitors in the prevention of cardiac hypertrophy and failure. Eicosanoids are potent modulators of immune responses and are derived from the 20-carbon atom arachidonic acids (AA). Epoxyeicosatrienoic acids (EETs) are derivatives of arachidonic acid (AA) generated through cytochrome P450 pathway. sEH catalizes the conversion of EETs to form the corresponding dihydroxyeicosatrienoic acids (DHETs). Recently, we have shown that several inhibitors of sEH exert beneficial effects in the prevention of cardiac hypertrophy and failure. Moreover, our study shows a beneficial effect of the compounds in the prevention of cardiac arrhythmias which occur in association with cardiac hypertrophy. Very little is known regarding the roles of this new class of compounds in the treatment of atrial arrhythmias. There is consequently an enormous opportunity to uncover a potentially very powerful class of compounds which may be used effectively in the clinical setting.
