The apical membrane of distal nephron epithelium (A6) had a Ca(2+)-activated outwardly rectifying Cl- channel with single-channel conductances of 3 pS for outward current and 0.8 pS for inward current. The single-channel conductance for inward current was dependent on cytosolic Ca2+ concentration. Insulin increased the single-channel conductance for the(More)
The apical membrane of distal nephron epithelium (A6) has a Ca(2+)-dependent outwardly rectifying Cl- channel with single channel conductances of 3 pS for outward current and 1 pS for inward current under the basal condition. The single channel conductance for inward currents increased as cytosolic Ca2+ concentration ([Ca2+]c) was elevated, while the single(More)
abstract It is currently believed that a nonselective cation (NSC) channel, which responds to arginine vasoto-cin (an antidiuretic hormone) and stretch, regulates Na ϩ absorption in the distal nephron. However, the mechanisms of regulation of this channel remain incompletely characterized. To study the mechanisms of regulation of this channel, we used renal(More)
