Potassium silicate improves cellular sodium homeostasis in wheat (Triticum aestivum L.) cultivars differing in salt resistance

Plant Biology, EarlyView.
Potassium silicate can decrease the uptake of sodium (Na+) into wheat cells by affecting the Na+ uptake channels and increasing ion homeostasis. Abstract Salinity causes negative impacts on crops. We investigated the effect of potassium silicate (K2SiO3) on the cytosolic uptake of sodium, [Na+]cyt, in mesophyll protoplasts of wheat cultivars differing ...

The Possible Role of TASK Channels in Rank-Ordered Recruitment of Motoneurons in the Dorsolateral Part of the Trigeminal Motor Nucleus. [PDF]

, 2016
Because a rank-ordered recruitment of motor units occurs during isometric contraction of jaw-closing muscles, jaw-closing motoneurons (MNs) may be recruited in a manner dependent on their soma sizes or input resistances (IRs). In the dorsolateral part of

Fmr1 knockout disrupts multiple intrinsic properties via reduced HCN channel activity in mediodorsal thalamocortical neurons

Experimental Physiology, EarlyView.
Abstract The neurodevelopmental disorder fragile X syndrome (FXS) results from hypermethylation of the FMR1 gene, which prevents production of the FMRP protein. FMRP modulates the expression and function of a variety of proteins, including voltage‐gated ion channels, such as hyperpolarization‐activated and cyclic nucleotide‐gated (HCN) channels, which ...

A new family of outwardly rectifying potassium channel proteins with two pore domains in tandem. [PDF]

, 1995
Potassium channels catalyse the permeation of K+ ions across cellular membranes and are identified by a common structural motif, a highly conserved signature sequence of eight amino acids in the P domain of each channel's pore-forming alpha-subunit. Here

Reduced GABA-B/GIRK-mediated regulation of the VTA following a single exposure to cocaine [PDF]

, 2012
In this paper, Arora and colleagues expand on their previous work on GIRK channels in the ventral tegmental area (VTA) presenting evidence that a single exposure to cocaine reduces inhibitory GABAergic transmission to dopamine (DA) neurons in the ventral

Changes in motor unit conduction velocity after unilateral lower‐limb suspension and active recovery are correlated with muscle ion channel gene expression

Experimental Physiology, EarlyView.
Abstract The effects of muscle disuse on the propagation of action potentials along motor unit (MU) muscle fibres, a key process for effective muscle activation and force generation, remain poorly understood. The aim of this study was to investigate changes in action potential propagation and to identify biological factors influencing these changes ...

Inwardly rectifying potassium channel 4.1 expression in post-traumatic syringomyelia

Neuroscience, 2016
Post-traumatic syringomyelia (PTS) is a serious neurological disorder characterized by fluid filled cavities that develop in the spinal cord. PTS is thought to be caused by an imbalance between fluid inflow and outflow in the spinal cord, but the underlying mechanisms are unknown.

Inwardly rectifying potassium channels (KIR) in GtoPdb v.2021.3

, 2023
The 2TM domain family of K channels are also known as the inward-rectifier K channel family. This family includes the strong inward-rectifier K channels (Kir2.x) that are constitutively active, the G-protein-activated inward-rectifier K channels (Kir3.x) and the ATP-sensitive K channels (Kir6.x, which combine with sulphonylurea receptors (SUR1-3)). The

GABAB receptor‐mediated modulation of sensory neuron excitability: Roles of CaV2.2, G‐protein‐coupled inwardly rectifying potassium (GIRK) channels, and hyperpolarisation‐activated cyclic nucleotide‐gated (HCN) channels in human and mouse nociception

Experimental Physiology, EarlyView.
Abstract Chronic visceral pain is a key symptom of irritable bowel syndrome. Modulation of voltage‐gated calcium and potassium channels by G protein‐coupled receptors plays a key role in dampening nociceptive transmission. Both baclofen and the analgesic peptide α‐conotoxin Vc1.1 activate GABAB receptors (GABABR), resulting in inhibition of CaV2.2 and ...
