Prostacyclin receptor regulation--from transcription to trafficking.

ABSTRACT: The prostacyclin receptor (IP--International Union of Pharmacology nomenclature) is a member of the seven transmembrane G-protein coupled receptor (GPCR) superfamily. Recent concerns with selective and non-selective COX-1/COX-2 inhibition have exposed an important cardioprotective role for IP in preventing atherothrombosis. Receptor dysfunction (genetic variants) or reduced signaling (COX-2 inhibition) in high cardiovascular risk patients leads to increased cardiovascular events. These clinical observations have also been confirmed genetically by mouse knockout studies. Thus, receptor regulation is paramount in ensuring correct function in the prevention of atherothrombosis. This review summarizes recent literature on how this important receptor is regulated, from transcription to transpor
