Abstract__ The AAV9 capsid displays a high natural affinity for the heart following a single intravenous IV administration in both newborn and adult mice. It also results in substantial albeit relatively lower expression levels in many other tissues. To increase the overall safety of this gene delivery method we sought to identify which one of a group of promoters is able to confer the highest level of cardiac specific expression and concurrently which is able to provide a broad biodistribution of expression across both cardiac and skeletal muscle. The in vivo behavior of five different promoters was compared CMV desmin Des alpha-myosin heavy chain a-MHC myosin light chain 2 MLC-2 and cardiac troponin C cTnC . Following IV .
