Endothelial ECE-1 involvement in constriction of retinal arterioles to big ET-1. Temporal course of vasoconstriction induced by big ET-1 (0.1 μM) was recorded in the presence (n = 7) or absence (n = 8) of endothelium. Control and denuded vessels with resting tone were treated with big ET-1 (0.1 μM) for 20 minutes. *P < 0.05 control versus denuded percentage resting diameters observed at 10, 15, and 20 minutes. R, resting diameter of vessels.
