Background

Reactive oxygen species (ROS) production increases after injury and potentially contributes to restenosis after angioplasty. We therefore evaluated the effect of adenovirus-mediated gene transfer (Ad) of superoxide dismutase (SOD) and catalase (CAT) on ROS production and restenosis after balloon angioplasty.

Methods

O(2)(-) and H(2)O(2 )production was quantified in cultured cells after incubation with either LPS or CuSO(4). Angioplasty and gene transfer were performed in rabbit atherosclerotic iliac arteries. One artery was injected with AdSOD and AdCAT, while the contralateral artery was injected with an adenovirus carrying no transgene, and served as control.

Results

ROS production was significantly decreased after adenovirus-mediated gene transfer of SOD and CAT as compared with control. Treated arteries showed less restenosis (32 +/- 27 vs. 63 +/-19%, p = 0.003) and less constrictive remodeling (1.2 +/- 0.3 vs. 0.9 +/-0.2, p = 0.02) than control arteries. Arteries injected with AdSOD and AdCAT showed better vasoreactivity to acetylcholine (11 +/- 4 vs. -1 +/-6%, p < 0.05), lower collagen density (43 +/- 16 vs. 53 +/-23%, p = 0.03), and lower inflammatory cell infiltration (22 +/- 6 vs. 36 +/-11%, p = 0.04) than control arteries.

Conclusions

Our data suggest that adenovirus-mediated gene transfer of SOD and CAT reduced oxidative stress, restenosis, collagen accumulation, and inflammation and improved endothelial function after angioplasty."xsd:string
