Vasopressin increases 45Ca2+ influx in rat aortic smooth muscle cells.

A Wallnöfer1, C Cauvin, U T Rüegg.   

Abstract

[Arg8]Vasopressin (AVP)-induced 45Ca2+ influx was examined in vascular smooth muscle cells derived from rat aorta. AVP stimulated the 45Ca2+ influx in a concentration-dependent manner. The effect was abolished in the presence of La3+. The dihydropyridine calcium channel antagonist darodipine did not affect the AVP-induced influx of 45Ca2+. These data suggest that AVP stimulates in these cultured aortic smooth muscle cells a receptor-operated channel (ROC) that is permeable to Ca2+.
