The aim of this study was to evaluate, using a rat model of balloon angioplasty, whether prostaglandin (PG) J2 and 2-cyclopenten-1-one are able to reduce restenosis. We found that both PGJ2 and 2-cyclopenten-1-one, administered by local application on carotid arteries, caused a dose-dependent inhibition of neointimal formation. Furthermore, both agents prevented vascular negative remodeling. The effect of these compounds on restenosis was correlated with an inhibition of nuclear factor-kB (NF-kB) activation as well as of intercellular adhesion molecule-1(ICAM-1 ) protein expression in injured carotid arteries of control animals. Our results show that cyclopentenone PGs and their derivatives reduce restenosis and may have therapeutic relevance for the prevention of human restenosis.

Abstract

The aim of this study was to evaluate, using a rat model of balloon angioplasty, whether prostaglandin (PG) J2 and 2-cyclopenten-1-one are able to reduce restenosis. We found that both PGJ2 and 2-cyclopenten-1-one, administered by local application on carotid arteries, caused a dose-dependent inhibition of neointimal formation. Furthermore, both agents prevented vascular negative remodeling. The effect of these compounds on restenosis was correlated with an inhibition of nuclear factor-kB (NF-kB) activation as well as of intercellular adhesion molecule-1(ICAM-1 ) protein expression in injured carotid arteries of control animals. Our results show that cyclopentenone PGs and their derivatives reduce restenosis and may have therapeutic relevance for the prevention of human restenosis.
