Potassium 79-88 IKAROS family zinc finger 1 Homo sapiens 100-103 10377339-6 1999 Only rostral hair cells exhibited an inactivating potassium current (IA), whereas an inwardly rectifying potassium current (IK1) was identified only in caudal AP hair cells. Potassium 105-114 IKAROS family zinc finger 1 Homo sapiens 124-127 15276477-1 2004 OBJECTIVE: The cardiac inwardly rectifying potassium current IK1 and its molecular correlates Kir2.1 and Kir2.2 play an important role in cardiac repolarisation and in the pathogenesis of hereditary long-QT syndrome (LQTS-7). Potassium 43-52 IKAROS family zinc finger 1 Homo sapiens 61-64 2335026-4 1990 Our aim was twofold: 1) to study the single-channel characteristics of potassium channels in human atrial single cells, present under basal conditions (iK1 and iK(ATP] or when stimulated with 10(-5) M acetylcholine; and 2) to calculate the contribution of these three channel types to the total basal potassium conductance in human atrial cells, and to compare the results with data on guinea pig atrial cells under the same conditions. Potassium 71-80 IKAROS family zinc finger 1 Homo sapiens 152-155 2335026-10 1990 The basal potassium conductance (i.e., in the absence of any exogenous hormone or neurotransmitter) was mainly due to iK1 channels in both human and guinea pig cells, a finding that is in contrast with previous reports. Potassium 10-19 IKAROS family zinc finger 1 Homo sapiens 118-121 2557769-2 1989 Recordings of the outward current(s), which is responsible for the resting potential and early repolarization of the action potential in human right atrium, consistently showed that this tissue has 1) a relatively small inwardly rectifying background potassium current (IK1) which generates the resting potential in mammalian ventricular tissue and Purkinje fibers, and 2) a large time- and voltage-dependent, but Ca2(+)-independent, transient outward current. Potassium 251-260 IKAROS family zinc finger 1 Homo sapiens 270-273 35548367-3 2022 Although changes in inward rectifier potassium currents including I K1 are known to contribute to the pathogenesis of fibrillation, the effect of sildenafil on I K1 has not been studied. Potassium 37-46 IKAROS family zinc finger 1 Homo sapiens 66-70 31868992-4 2020 One of the main challenges of hiPSC-CMs is the physiologic expression of ion channels such as the inward rectifiers (e.g., Kir2.1-2.3), which conduct the cardiac inward rectifier potassium current (IK1 ). Potassium 179-188 IKAROS family zinc finger 1 Homo sapiens 198-201 558594-8 1977 Alteration in potassium driving force over time results in a time-dependent ik1 even though the underlying conductance is time-independent [29]. Potassium 14-23 IKAROS family zinc finger 1 Homo sapiens 76-79 33229908-3 2021 Various approaches are used to overcome this drawback, including the injection of a "synthetic" inward rectifier potassium current (IK1), which is computed in real time, based on the recorded membrane potential ("dynamic clamp"). Potassium 113-122 IKAROS family zinc finger 1 Homo sapiens 132-135 31827438-2 2019 We explored if blocking the background and the acetylcholine-activated inward rectifier potassium currents (IK1 and IKACh) could be antiarrhythmic in persistent atrial fibrillation. Potassium 88-97 IKAROS family zinc finger 1 Homo sapiens 108-111 31946747-2 2019 Previous experimental studies have shown that biological pacemaker could be produced by genetically manipulating non-pacemaking cardiac cells by suppressing the inward rectifier potassium current (IK1) and expressing the hyperpolarization- activated current (If). Potassium 178-187 IKAROS family zinc finger 1 Homo sapiens 197-200 29245016-12 2018 Finally, electrophysiological studies showed that the inwardly rectifying potassium current (IK1) was evenly present in AF- and Ctr-CMPC in basal conditions and similarly disappeared after TGF-beta1 exposure. Potassium 74-83 IKAROS family zinc finger 1 Homo sapiens 93-96 30835490-6 2019 We reproduced key electrophysiological and pharmacological features known for native IK1, including current enhancement by external potassium and voltage- and concentration-dependent blockade by external barium. Potassium 132-141 IKAROS family zinc finger 1 Homo sapiens 85-88 27895596-1 2016 The inwardly rectifying potassium current (IK1) and the fast inward sodium current (INa) are reciprocally modulated in mammalian ventricular myocytes. Potassium 24-33 IKAROS family zinc finger 1 Homo sapiens 43-46 27895596-12 2016 Reciprocal modulation of the inwardly rectifying potassium current and the fast inward sodium current may have a functional role in allowing cardiac tissue to remain excitable when IK1 is upregulated. Potassium 49-58 IKAROS family zinc finger 1 Homo sapiens 181-184 26057242-4 2015 Our goal is to determine if the inward rectifying potassium current (IK1) causes the inhibition of hyperpolarization.
