Reduction of Kcnt1 is therapeutic in mouse models of SCN1A and SCN8A epilepsy
Frontiers in Neuroscience, 2023 Developmental and epileptic encephalopathies (DEEs) are severe seizure disorders with inadequate treatment options. Gain- or loss-of-function mutations of neuronal ion channel genes, including potassium channels and voltage-gated sodium channels, are ...

The conduction pathway of potassium channels is water free under physiological conditions. [PDF]
, 2019 Ion conduction through potassium channels is a fundamental process of life. On the basis of crystallographic data, it was originally proposed that potassium ions and water molecules are transported through the selectivity filter in an alternating ...

VKCDB: Voltage-gated potassium channel database
BMC Bioinformatics, 2004 Background The family of voltage-gated potassium channels comprises a functionally diverse group of membrane proteins. They help maintain and regulate the potassium ion-based component of the membrane potential and are thus central to many critical ...

Depolarization of sperm membrane potential is a common feature of men with subfertility and is associated with low fertilization rate at IVF [PDF]
, 2016 STUDY QUESTION. Are significant abnormalities in outward (K+) conductance and resting membrane potential (Vm) present in the spermatozoa of patients undertaking IVF and ICSI and if so, what is their functional effect on fertilization success?

Modeled channel distributions explain extracellular recordings from cultured neurons sealed to microelectrodes [PDF]
, 2002 Amplitudes and shapes of extracellular recordings from single neurons cultured on a substrate embedded microelectrode depend not only on the volume conducting properties of the neuron-electrode interface, but might also depend on the distribution of ...

Potassium Channels in Epilepsy [PDF]
Cold Spring Harbor Perspectives in Medicine, 2016 This review attempts to give a concise and up-to-date overview on the role of potassium channels in epilepsies. Their role can be defined from a genetic perspective, focusing on variants and de novo mutations identified in genetic studies or animal models with targeted, specific mutations in genes coding for a member of the large potassium channel ...

Mechanism of resveratrol-induced relaxation in the human gallbladder
BMC Complementary and Alternative Medicine, 2017 Background Resveratrol is a polyphenolic compound extracted from plants and is also a constituent of red wine. Resveratrol produces relaxation of vascular smooth muscle and may prevent cardiovascular diseases.

A new familial form of a late-onset, persistent hyperinsulinemic hypoglycemia of infancy caused by a novel mutation in KCNJ11. [PDF]
, 2017 The ATP-sensitive potassium channel (KATP) functions as a metabo-electric transducer in regulating insulin secretion from pancreatic β-cells. The pancreatic KATP channel is composed of a pore-forming inwardly-rectifying potassium channel, Kir6.2, and a ...

Single-channel recordings from cultured human retinal pigment epithelial cells. [PDF]
, 1988 We have applied patch-clamp techniques to on-cell and excised-membrane patches from human retinal pigment epithelial cells in tissue culture. Single-channel currents from at least four ion channel types were observed: three or more potassium-selective ...
