(a, b) Calculation for contribution of Ca2+ influx through three types of VICCs to ET-1-induced arachidonic acid release in VSMCs in the presence of 1 μM nifedipine. The ET-1-induced arachidonic acid release in the presence of 10 μM LOE 908 and/or 10 μM SK&F 96365 is represented as a percentage of values in its absence. The contributions of SOCC and NSCC-1 are represented as X and Z, respectively. The contribution of NSCC-2 is represented as W–Z or Y–X.
