Abstract
Double-stranded DNA with high affinity to E2F as a decoy cis-element blocks the
activation of genes mediating the cell cycle, resulting in effective suppression of the
smooth muscle cell proliferation that causes intimal hyperplasia. To evaluate the effect
of the E2F decoy to suppress neointimal hyperplasia autogenous venous bypass grafts
were performed in dogs after incubation with heparin (group 1), with E2F decoy
oligodeoxynucleotides (ODN) (groups 2 and 3), or with a random ODN (group 4)
using a Japan-liposomeal method based on a hemagglutinating virus. The intimal and
medial cross-sectional surface area of the anastomotic site was measured at 4 months
after bypass surgery in groups 1, 3, and 4 by computerized planimetry and at 4 weeks
in group 2 to compare the intimal/medial (I/M) area ratios. Autogenous vein grafts
treated with E2F decoy showed a significant reduction in I/M area ratio (0.26± 0.11)
compared with the heparin-treated control group (1.49 ± 0.29) or the mismatched
ODN-treated group (1.61 ± 0.28; P = .000). There was no difference in the I/M area
ratio according to experimental periods (groups 2 vs 3: 0.26 ± 0.11 vs 0.37 ±
0.32; P =.446) or the anastomotic sites (proximal vs distal; P = .934). In conclusion,
an E2F decoy can suppress neointimal hyperplasia in autogenous vein grafts, which
may prolong patency by reducing graft stenosis.
