Long term inhibition of neointima formation in balloon-injured rat arteries by intraluminal instillation of a matrix-targeted retroviral vector bearing a cytocidal mutant cyclin G1 construct
Restenosis from neointimal proliferation is a frequent complication of intracoronary stenting and catheter-based revascularization procedures. Currently, there is no known therapeutic strategy that has been sufficiently effective to warrant its widespread use. In the present study, the anti-proliferative properties of a matrix (collagen)-targeted retroviral vector bearing a mutant cyclin G1 (DNT 41-249) construct was evaluated in vitro and in vivo. In controlled one-month efficacy studies, the intraluminal instillation of the mutant cyclin G1 vector significantly inhibited neointima lesion formation in balloon-injured rat arteries without
neointimal growth, associated necrosis or intense inflammatory reaction. Taken together, these data extend the potential utility of the matrix-targeted mutant cyclin G1 retroviral vector for management of vascular
