OBJECTIVE Prostacyclin synthase (PGIS) gene transfer have been shown to accelerate re-endothelialization and prevent neointimal formation in balloon-injured arteries. The aim of this study is to evaluate how overexpression of endogenous prostacyclin exerts those beneficial effects in atheromatous arteries. METHODS New Zealand White Rabbits fed a 0.5%(More)
1. Angiotensin-converting enzyme (ACE) inhibitors have been shown to improve insulin-resistance both experimentally and clinically. We therefore investigated the effects of quinapril, which has high tissue specificity for ACE, regarding the contribution of insulin to vascular contractions, as well as insulin sensitivity in a dietary rat model of insulin(More)
Previous studies have shown that prostacyclin (PGI(2)) synthase (PCS) gene transfer inhibits neointimal formation in balloon-injured arteries. However, the role of each cyclooxygenase (COX) isoform in this healing mechanism remains unknown. We hypothesized that overexpression of PCS may modulate COX-2-mediated prostaglandin (PG) metabolism. That is to say,(More)
