Key result
Adjunctive ultrasound boosts vascular smooth muscle gene expression ~7.5-fold in vitro.
Why the study?
Progress in local gene therapy to prevent restenosis after PCI has been hindered by safety and efficacy concerns of viral vectors and limited efficiency of nonviral techniques.
Does adjunctive ultrasound exposure enhance nonviral gene delivery in cultured porcine vascular cells?

Not ready for clinical use; leaves open ultrasound's role in vascular gene therapy pending in vivo validation.
Does adjunctive ultrasound exposure enhance nonviral gene delivery in cultured porcine vascular cells?
Effect estimate: 7.5-fold and 2.4-fold enhancement
Adjunctive ultrasound exposure enhances nonviral gene delivery in vascular cells in vitro, suggesting potential for ultrasound-assisted local gene therapy to prevent restenosis.
Lawrie et al. (1999) studied Restenosis. Adjunctive ultrasound exposure (USE) vs. No ultrasound exposure was evaluated on Luciferase reporter gene expression (activity) (7.5-fold and 2.4-fold enhancement). Adjunctive ultrasound exposure enhanced luciferase reporter gene expression by 7.5-fold in vascular smooth muscle cells and 2.4-fold in endothelial cells in vitro.
