Previous studies have demonstrated that muscle can take up and express naked DNA or RNA. This study demonstrates that the pDNA can be delivered to and expressed within skeletal muscle when injected rapidly, in a large volume and when all blood vessels leading into and out of the hindlimb are occluded. The additional use of collagenase, papaverine and ischemia raised expression moderately but was not critical. These results demonstrate that a nonviral method can lead to high levels of expression in the muscles of adult animals large than mice.
