The Effect of Oligonucleotides to c-myb on Vascular Smooth Muscle Cell Proliferation and Neointima Formation After Porcine Coronary Angioplasty
Proto-oncogenes, including c-myb, are expressed early after vascular injury. The application of antisense oligodeoxynucleotides (AS-ODNs) against these genes inhibits cell proliferation and neointima formation in small animals and in peripheral arteries.

description | Proto-oncogenes, including c-myb, are expressed early after vascular injury. The application of antisense oligodeoxynucleotides (AS-ODNs) against these genes inhibits cell proliferation and neointima formation in small animals and in peripheral arteries. The aim of this study was to investigate the specificity of action of AS-ODN-c-myb in vitro and to assess its effect, when delivered locally, on neointima formation after percutaneous transluminal coronary angioplasty (PTCA) in porcine coronary arteries. AS-ODN-c-myb inhibited the proliferation of vascular smooth muscle cells (VSMCs) in vitro in a dose-dependent manner. There was a corresponding reduction in steady state levels of c-myb mRNA and protein. Expression of another early gene, c-fos, was unaffected. S1 nuclease analysis demonstrated intact full-length AS-ODN-c-myb retrieved from VSMCs in culture after 12 hours. A range of ODNs, related and unrelated to c-myb, with and without a GGGG sequence, inhibited VSMC proliferation. Phosphorothioated AS-ODN-c-myb was 30 times less potent than unphosphorothioated AS-ODN-c-myb. PTCA induced porcine coronary artery neointima formation. c-myb mRNA was maximally induced 18 hours after injury. Unmodified AS-ODN-c-myb, sense-ODN-c-myb, saline, or nothing was delivered immediately after balloon dilatation via a double-skinned porous balloon (Transport, SciMed). Fluorescence-labeled AS-ODN-c-myb was deposited throughout the vessel wall. Mean maximum intima/media cross-sectional area 4 weeks after PTCA was reduced with AS-ODN-c-myb by 79% compared with saline (P |

Fluorescence-labeled AS-ODN-c-myb was deposited throughout the vessel wall. Mean maximum intima/media cross-sectional area 4 weeks after PTCA was reduced with AS-ODN-c-myb by 79% compared with saline (P<.05), 82% compared with sense-ODN-c-myb, and 63% compared with nothing (P<.10). Conclusions are as follows(1) c-myb is expressed in VSMCs after vascular injury. (2) AS-ODN-c-myb is retained intact in VSMCs, reducing their proliferation in vitro in dose-dependent fashion, with reduction in c-myb mRNA and protein, whereas sense-ODN-c-myb is not. (3) A range of ODNs can reduce VSMC proliferation by a non-sequence-specific mechanism. (4) Phosphorothioate protection of antisense molecules may reduce their efficacy. (5) Local delivery of unmodified AS-ODN-c-myb via the Transport catheter reduces neointima formation after porcine PTCA. (6) Local delivery of fluid may exacerbate neointimal thickening.
