Inwardly rectifying potassium channels in Drosophila [PDF]

, 2013
Inwardly rectifying potassium channels (Kir) are a special subset of potassium selective ion channels which pass potassium more easily into rather than out of the cell. These channels mediate a variety of cellular functions, including control of membrane

Age‐ and sex‐specific modulation of human cardiac electrophysiology by doxorubicin

The Journal of Physiology, EarlyView.
Abstract figure legend DOX differentially impacts cardiac electrophysiology based on sex and age. Sex differences were primarily observed among younger hearts, where action potential duration (APD) prolongation was observed in females, but not in males. Created using BioRender. George, S. (2026) https://BioRender.com/wresf1k Abstract Acute doxorubicin (

Inwardly Rectifying Potassium Channels in Drosophila Regulate the Sleep/Wake Behaviour through PDF-Neurons

, 2019
Potassium channels are important modulators of cell function depending on the cell type of where they are expressed. They are involved in regulation of cell membrane resting potential, potassium homeostasis and control a variety of cellular functions ...

Remodelling of human atrial K+ currents but not ion channel expression by chronic β-blockade [PDF]

, 2011
Chronic β-adrenoceptor antagonist (β-blocker) treatment in patients is associated with a potentially anti-arrhythmic prolongation of the atrial action potential duration (APD), which may involve remodelling of repolarising K+ currents.

Cloning, functional expression, and pharmacological characterization of inwardly rectifying potassium channels (Kir) from Apis mellifera

Scientific Reports
Potassium channels belong to the super family of ion channels and play a fundamental role in cell excitability. Kir channels are potassium channels with an inwardly rectifying property.

The ultrarapid delayed rectifier potassium current has important functional role in the repolarization reserve of canine and human ventricular muscle

The Journal of Physiology, EarlyView.
Abstract figure legend The ultrarapid delayed rectifier potassium current (IKur) has long been considered an atrial‐specific current with no functional role in the ventricles, despite evidence of its expression in ventricular myocytes. In the present study we challenged this prevailing concept and investigated the potential role of IKur in ventricular ...

Maturation of spinal motor control through developmental changes in ion currents

The Journal of Physiology, EarlyView.
Abstract figure legend Ion channels of spinal neurons have been shown to change during development in a wide range of species. These changes occur at specific stages of development. An important developmental process is the maturation of motor control by which the body acquires new movements or refines movements already present.

Immunolocalization of KATP channel subunits in mouse and rat cardiac myocytes and the coronary vasculature. [PDF]

, 2005
BACKGROUND: Electrophysiological data suggest that cardiac KATP channels consist of Kir6.2 and SUR2A subunits, but the distribution of these (and other KATP channel subunits) is poorly defined.
