Outline of Final Research Achievements |
APJ is a G protein-coupled receptor and highly expressed in various cardiovascular tissues. Although the physiological function of APJ on vascular endothelial cells was identified as a hypotensive system, its action on vascular smooth muscle cells (VSMCs) is still unclear. To examine the physiological role of APJ on VSMCs, we generated transgenic mice expressing APJ specifically in VSMCs, called SMA-APJ. Interestingly, I found sustained bradycardia and the development of coronary stenosis in SMA-APJ following apelin administration. An ex vivo assay using the Easy Magnus System revealed that the aorta of SMA-APJ was contracted intensively when co-stimulated with apelin and noradrenaline, a ligand of α1-adrenergic receptor (α1-AR).
