My laboratory studies regulation of expression and function of cardiac ion channels in development and disease, and explores methods of gene and cell therapy to treat brady and tachyarrhythmias. Cell therapy approaches take advantage of the fact that adult mesenchymal stem cells have endogenous gap junctions that will couple with those present in myocardial cells. Thus, a stem cell that is engineered to express specific ion channels will effectively deliver the current passing through those channels into contiguous cardiac cells via these gap junctions. This approach does not require the stem cell to differentiate into a cardiac cell, but only to electrically couple to the cardiac cell and maintain expression of the exogenous channel gene. Related research with collaborators explores the utility of this gap junctional pathway for delivering small molecules into target cells, including siRNA.
