Association between dietary potassium intake and severe headache or migraine in US adults: a population-based analysis

open access: yesFrontiers in Nutrition, 2023
BackgroundMigraine is a prevalent neurovascular headache disorder. The link between dietary potassium and blood pressure has been established. We sought to delineate the relationship between dietary potassium intake and the prevalence of migraines ...

Nicorandil-Induced Hyperkalemia in a Uremic Patient

open access: yesCase Reports in Medicine, 2012
Nicorandil is an antianginal agent with nitrate-like and ATP-sensitive potassium channel activator properties. After activation of potassium channels, potassium ions are expelled out of the cells, which lead to membrane hyperpolarization, closure of ...

Expression of ATP-sensitive potassium channels in human pregnant myometrium

open access: yesReproductive Biology and Endocrinology, 2011
Background Potassium channels play critical roles in the regulation of cell membrane potential, which is central to the excitability of myometrium. The ATP-sensitive potassium (KATP) channel is one of the most abundant potassium channels in myometrium ...

Multidimensional Regulation of Cardiac Mitochondrial Potassium Channels

open access: yesCells, 2021
Mitochondria play a fundamental role in the energetics of cardiac cells. Moreover, mitochondria are involved in cardiac ischemia/reperfusion injury by opening the mitochondrial permeability transition pore which is the major cause of cell death.

Identification of putative potassium channel homologues in pathogenic protozoa [PDF]

open access: yes, 2012
K(+) channels play a vital homeostatic role in cells and abnormal activity of these channels can dramatically alter cell function and survival, suggesting that they might be attractive drug targets in pathogenic organisms.

ATP-Sensitive Potassium Channels in the Cerebral Circulation [PDF]

open access: yesStroke, 2003
Background— In brain blood vessels, electrophysiological studies proving the existence of ATP-sensitive potassium channels (K ATP ) are scarce. However, numerous pharmacological studies establish the importance of K ATP channels in these blood vessels ...

Ion Channel Dysfunction in Astrocytes in Neurodegenerative Diseases

open access: yesFrontiers in Physiology, 2022
Astrocytes play an important role in the central nervous system (CNS). Ion channels in these cells not only function in ion transport, and maintain water/ion metabolism homeostasis, but also participate in physiological processes of neurons and glial ...

Anionic Phospholipids Activate ATP-sensitive Potassium Channels [PDF]

open access: yesJournal of Biological Chemistry, 1997
The ATP-sensitive potassium channel (KATP) controls insulin release in pancreatic beta-cells and also modulates important functions in other cell types. In this study we report that anionic phospholipids activated KATP in pancreatic beta-cells, cardiac myocytes, skeletal muscle cells, and a cloned KATP composed of two subunits (SUR/Kir6.

The selectivity, voltage-dependence and acid sensitivity of the tandem pore potassium channel TASK-1 : contributions of the pore domains [PDF]

open access: yes, 2007
We have investigated the contribution to ionic selectivity of residues in the selectivity filter and pore helices of the P1 and P2 domains in the acid sensitive potassium channel TASK-1.

Membrane trafficking of ATP-sensitive potassium channels [PDF]

open access: yes, 2005
ATP-sensitive potassium (KATp) channels are known to play a vital role in the regulation of insulin secretion from pancreatic 0-cells. Changes in the ratio of [ATP]/[ADP] within the cell are known to regulate the activity of channels, but very little is ...
