Gene transfer strategies for augmenting cardiac function

Recent transgenic as well as gene-targeted animal models have greatly increased our understanding of the molecular mechanisms of normal and compromised heart function. These studies have raised the possibility of using somatic gene transfer as a means for improving cardiac function. DNA transfer to a significant portion of the myocardium has thus far been difficult to accomplish. This review describes current efforts to achieve myocardial gene transfer in several model systems, with particular emphasis placed on adenovirus-mediated gene delivery, its possibilities, and current limitations.
