Release of Ca2+ by noradrenaline and ATP from the same Ca2+ store sensitive to both InsP3 and Ca2+ in rat portal vein myocytes.
1. Changes in cytosolic free Ca2+ concentration ([Ca2+]i) induced by noradrenaline (NA) and ATP were investigated using indo-1 microspectrofluorimetry in single smooth muscle cells of rat portal vein. 2. Activation of P2x-purinoceptors by ATP (10 microM) increased [Ca2+]i from 92 +/- 7 nM (n = 18) t...
