Figure 1 Experimental protocol. The amount of virus applied to the jugular vein is expressed in infectious units (IU). Abbreviations are: AV, arteriovenous; Ad.CNP, adenoviral vector encoding murine C-type natriuretic peptide; β-gal, β-galactosidase; RT-PCR, reverse transcription-polymerase chain reaction; RIA, radioimmunoassay.

Figure 2 Gene expression 3days after transduction with adenoviral vector encoding murine C-type natriuretic peptide (Ad.CNP) or Ad.mock, analyzed by reverse transcription-polymerase chain reaction (RT-PCR). Left panel shows gene expression in cultured porcine fibroblasts. (lanes 1 and 2, Ad.mock-transduced fibroblasts; lanes 3 and 4, Ad.CNP-transduced fibroblasts). Right panel shows the gene expression after in vivo gene transfer (lane 5, Ad.mock-transduced vein; lane 6, Ad.CNP-transduced vein). The amount of β-actin mRNA was used as internal standards.

Figure 3 Effect of C-type natriuretic peptide (CNP)-22 and adenoviral vector encoding murine C-type natriuretic peptide (Ad.CNP) transduction on the migration of cultured porcine vein fibroblasts. Values are expressed as the mean percentage ± SEM of migrated cells, as compared with the positive control and Ad.mock, respectively. The negative control represents fibroblast migration without fetal calf serum (FCS) stimulation. *P = 0.05; **P = 0.04.

Figure 4 Representative Elastin von Gieson–stained 5 μm section of an adenoviral (Ad.mock)-transduced (A) and adreoviral vector encoding murine C-type natriuretic peptide (Ad.CNP)-transduced (B) vein (original magnification 12.5×). (C) Detail of Ad.LacZ-transduced vein, 3days after transduction (original magnification 100×). (D) Detail of α-smooth muscle cell actin–stained section. The dotted line indicated the boundary of the neointima area (original magnification 200×). The intima predominantly consists of vascular smooth muscle cells (VSMC).
