The effects of angiotensin-converting enzyme (ACE) inhibitors on intracellular calcium concentration ([Ca2+]i) were examined under resting conditions and after stimulation with bradykinin in cultured human umbilical vein endothelial cells. The ACE inhibitors ramiprilat and enalaprilat (0.3 microM) enhanced the increase in [Ca2+]i elicited by bradykinin (3 nM) and also caused an increase in resting [Ca2+]i when given alone. This increase in resting [Ca2+]i was long-lasting and accompanied by an increased formation of nitric oxide, as assessed by a NG-nitro-L-arginine-sensitive cyclic GMP accumulation in the cells. Both increases in resting [Ca2+]i and nitric oxide production by ACE inhibitors were inhibited by preincubation of the cells with the B2-receptor antagonist Hoe 140. These data indicate that ACE inhibitors are able to unmask a release of bradykinin from cultured human endothelial cells. This endothelium-derived bradykinin can exert an autocrine function by stimulating endothelial B2-receptors with a subsequent increase in [Ca2+]i and nitric oxide formation.
