Abstract:
Mitochondrial potassium channels have been described as important factors in cell pro-life and death phenomena. The activation of mitochondrial potassium channels, such as ATP-regulated or calcium-activated large conductance potassium channels, may have cytoprotective effects in cardiac or neuronal tissue. It has also been shown that inhibition of the mitochondrial Kv1.3 channel may lead to cancer cell death. Hence, in this paper, we examine the concept of the druggability of mitochondrial potassium channels. To what extent are mitochondrial potassium channels an important, novel, and promising drug target in various organs and tissues? The druggability of mitochondrial potassium channels will be discussed within the context of channel molecular identity, the specificity of potassium channel openers and inhibitors, and the unique regulatory properties of mitochondrial potassium channels. Future prospects of the druggability concept of mitochondrial potassium channels will be evaluated in this paper.

Abstract:
Potassium channels are pore-forming transmembrane proteins that regulate a multitude of biological processes by controlling potassium flow across cell membranes. Aberrant potassium channel functions contribute to diseases such as epilepsy, cardiac arrhythmia, and neuromuscular symptoms collectively known as channelopathies. Increasing evidence suggests that cancer constitutes another category of channelopathies associated with dysregulated channel expression. Indeed, potassium channel–modulating agents have demonstrated antitumor efficacy. Potassium channels regulate cancer cell behaviors such as proliferation and migration through both canonical ion permeation–dependent and noncanonical ion permeation–independent functions. Given their cell surface localization and well-known pharmacology, pharmacological strategies to target potassium channel could prove to be promising cancer therapeutics.

Abstract:
The Ca2+ ion is used ubiquitously as an intracellular signaling molecule due to its high external and low internal concentration. Many Ca2+-sensing ion channel proteins have evolved to receive and propagate Ca2+ signals. Among them are the Ca2+-activated potassium channels, a large family of potassium channels activated by rises in cytosolic calcium in response to Ca2+ influx via Ca2+-permeable channels that open during the action potential or Ca2+ release from the endoplasmic reticulum. The Ca2+ sensitivity of these channels allows internal Ca2+ to regulate the electrical activity of the cell membrane. Activating these potassium channels controls many physiological processes, from the firing properties of neurons to the control of transmitter release. This review will discuss what is understood about the Ca2+ sensitivity of the two best-studied groups of Ca2+-sensitive potassium channels: large-conductance Ca2+-activated K+ channels, KCa1.1, and small/intermediate-conductance Ca2+-activated K+ channels, KCa2.x/KCa3.1.

Abstract:
We have examined the actions of histidine-specific reagents on potassium channels in squid giant axons. External application of 20-500 microM diethylpyrocarbonate (DEP) slowed the opening of potassium channels with little or no effect on closing rates. Sodium channels were not affected by these low external concentrations of DEP. Internal application of up to 2 mM DEP had no effect on potassium channel kinetics. Steady-state potassium channel currents were reduced in an apparently voltage-dependent manner by external treatment with this reagent. The shape of the instantaneous current-voltage relation was not altered. The voltage-dependent probability of channel opening was shifted toward more positive membrane potentials, thus accounting for the apparent voltage-dependent reduction of steady-state current. Histidine-specific photo-oxidation catalyzed by rose bengal produced alterations in potassium channel properties similar to those observed with DEP. The rate of action of DEP was consistent with a single kinetic class of histidine residues. In contrast to the effects on ionic currents, potassium channel gating currents were not modified by treatment with DEP. These results suggest the existence of a histidyl group (or groups) on the external surface of potassium channels important for a weakly voltage-dependent conformational transition. These effects can be reproduced by a simple kinetic model of potassium channels.

Abstract:
Background: Potassium (K+) channels participate in many physiological processes, cardiac function, cell proliferation, neuronal signaling, muscle contractility, immune function, hormone secretion, osmotic pressure, changes in gene expression, and are involved in critical biological functions, and in a variety of diseases. Potassium channels represent a large family of tetrameric membrane proteins. Potassium channels activation reduces excitability, whereas channel inhibition increases excitability. Objective: Small molecule K+ channel activators and inhibitors interact with voltage-gated, inward rectifying, and two-pore tandem potassium channels. Due to their involvement in biological functions, and in a variety of diseases, small molecules as potassium channel modulators have received great scientific attention. Methods: : In this review, we have compiled the literature, patents and patent applications (2011 to 2017) related to different chemical classes of potassium channel openers and blockers as therapeutic agents for the treatment of various diseases. Many different chemical classes of selective small molecule have emerged as potassium channel modulators over the past years. Conclusion: This review discussed the current understanding of medicinal chemistry research in the field of potassium channel modulators to update the key advances in this field.

Abstract:
Migraine is a primary headache disorder ranked as the leading cause of years lived with disability among individuals younger than 50 years. The aetiology of migraine is complex and might involve several molecules of different signalling pathways. Emerging evidence implicates potassium channels, predominantly ATP-sensitive potassium (KATP) channels and large (big) calcium-sensitive potassium (BKCa) channels in migraine attack initiation. Basic neuroscience revealed that stimulation of potassium channels activated and sensitized trigeminovascular neurons. Clinical trials showed that administration of potassium channel openers caused headache and migraine attack associated with dilation of cephalic arteries. The present review highlights the molecular structure and physiological function of KATP and BKCa channels, presents recent insights into the role of potassium channels in migraine pathophysiology, and discusses possible complementary effects and interdependence of potassium channels in migraine attack initiation.

Abstract:
This study uses the structural coordinates of the determined K+ channels to create comparative models of three diverse members of this family, with the aim of enabling a better understanding of the function of these channels. The K+ channel of primary interest is the hERG K+ channel. The pharmacology of this channel is of considerable interest as serendipitous block of K+ conduction pore may result in cardiac arrest. A set of known antagonists have been docked into novel comparative models of hERG to propose how these drugs interact with the channel. The models have also been subjected to molecular dynamics simulations to investigate the drug binding in more detail and to gain a structural understanding of two critical biophysical properties of this channel: activation and inactivation. Additionally, ancillary domains of the channel have been modelled to provide a tool for interpreting detailed structure-function relationships for the hERG channel. The second channel investigated is the TASK-1 channel. Comparative models of this channel have been created to evaluate mutations that alter selectivity and pH sensitivity. The final K+ channel studied is the Kir2.1 channel. A fundamental property of this channel is its block by polyamines, which prevents the efflux of K+. Comparative models have been created, with a series of polyamine analogues docked into the membrane and cytoplasmic pore regions of this channel. Overall, this study has illuminated the structural basis of several biophysical properties that are intrinsic to normal K+ channel function.

Abstract:
The pancreatic ATP-sensitive potassium (KATP) channels couple glucose metabolism to excitability of the pancreatic β-cells to regulate insulin secretion. The channel subunits, Kir6.2 and SUR1, are encoded by the KCNJ11 and ABCC8 genes respectively. Genetic polymorphisms in these genes, which reduce channel activity, cause congenital hyperinsulinism (CHI) characterized by insulin hyper-secretion and hypoglycemia. The hERG (human ether-a-go-go related gene) potassium channels,encoded by the KCNH2 gene, contribute to the rapidly activating delayed rectifier K+ current (IKr), which is responsible for rapid repolarisation of the cardiac action potential. Decreased hERG channel function causes the Long QT syndrome 2 (LQTS2) and life threatening cardiac arrhythmias. Several mutations in these two clinically important potassium ion channels alter their surface density leading to disease. Therefore, it is of fundamental importance to investigate the trafficking mechanisms that regulate the surface density of these channels. Techniques in cell biology, molecular biology and biochemistry were employed to identify the molecular basis of Sar1-GTPase dependent ER exit of the KATP and hERG channels in COPII vesicles. Blocking the cargo binding sites on the Sec24 protein of the COPII coat with membrane-permeable synthetic peptides prevented ER exit of both these channels. While the diacidic 280DLE282 sequence on the Kir6.2 subunit of KATP channels was found to be the ER exit motif required for entry of the channels into COPII vesicles at the ER exit sites, such a motif was found to be absent on hERG Cterminus. Further, endocytic trafficking mechanism of hERG channels was studied in recombinant (HEK MSRII and HeLa) and native (neonatal rat cardiac myocytes) systems using cell biological and pharmacological tools. hERG channels were found to be internalised by a dynamin-independent, raft-mediated, and ARF6-dependent pathway. A prolonged block of this pathway revealed that the channels could also undergo internalisation by an alternate dynamin-mediated pathway. Internalised hERG channels were found to recycle back to the cell surface and undergo lysosomal degradation. Degradation of the channels was enhanced when Rab11a-GTPase function was disrupted leading to reduced surface density indicating that recycling is crucial to maintain cell surface density of the channels. Thus this study investigated and compared the previously unknown mechanisms of biosynthetic and endosomal trafficking of the KATP and hERG potassium channels with a conclusion that these processes play an important role in maintaining surface density and thereby in the function of these channels in physiological and patho-physiological conditions.

Abstract:
Potassium channels control the conduction of K+ across cell membranes, down their electrochemical gradient. This rapid and highly selective movement of K+ is essential to many biological processes. K+ channels are largely alpha helical, tetrameric proteins that span the lipid bilayer. Diversity in K+ channels arises primarily in the mechanism of gating by various ligands or voltage; however, the basic structural elements, notably the selectivity filter are conserved within the family. Studies ~n this thesis focus on the single-channel behaviour of the K+ channels KcsA and Kcv. KcsA is a proton-activated channel from the bacterium Streptomyces lividans and its crystal structure was the first of a K+ channel to be solved. Kcv expressed by the Paramecium bursaria Chlorella virus is the smallest known K+ channel and thus represents the minimal structural entity necessary to form a functional and selective pore. Studies on the bacterial inward rectifying channels, KirBacs, have also been initiated. The KirBacs are a superfamily of prokaryotic channels homologous to eukaryotic Kir channels. In this work, KcsA and Kcv were found to form stable tetramers, which can be expressed by coupled in vitro transcription and translation and purified by polyacrylamide gel electrophoresis. The purified tetramers were reconstituted into planar lipid bilayers and studied at the single-channel level. Through single-channel recordings the ionic selectivity, gating behaviour, functional effects of site-directed mutagenesis and the interaction between Kcv and blockers have been studied. In addition, single-channel studies at elevated temperatures have revealed the remarkable thermostability of Kcv, as well as insight into the transport of ions through a narrow and selective pore. Through temperature studies, it has been possible to obtain the thermodynamic and kinetic parameters describing Kcv activity.

Abstract:
Limbic encephalitis (LE) is a central nervous system disorder that is characterised by memory impairments, confusion, agitation and seizures, and associated with hyperintense lesions of the medial temporal lobe, seen with MRI. Anti-voltage-gated potassium channel (VOKC) antibodies have been been detected in the plasma of a subset of LE patients using a 125I-a-dendrotoxin (a-DTX) radioimmunoprecipitation assay, suggesting that the likely antigens are VOKC Kv1.l, 1.2 and 1.6 subunits. Symptoms of the disease improve markedly with immunosuppression, correlating with similarly dramatic falls in the titre of anti-VOKC antibodies, thus implicating anti-VOKC antibodies in the pathogenesis of LE. Circumstantial evidence from studies of inherited channelopathies and animal models of reduced VOKC activity suggests that VOKC dysfunction may contribute to the pathogenesis of LE. This thesis addresses whether anti-VOKC antibodies (i) bind to a-DTX-sensitive subunits and (ii) affect VOKC function. Immunofluorescence data show that binding of LE patient IgO to the surface of primary neurons and Kvl-expressing HEK-293/HEKTSA cells could not be detected with indirect immunofluorescence. Comparison of intracellular labelling with patient and control IgO showed that no additional labelling could be detected with LE patient IgO. Electrophysiological data show first, that a-DTXsensitive currents could not be reliably isolated from primary cultured hippocampal neurons; second, that NMT or LE samples did not affect VOKCs expressed by neuroblastoma-l cells; third, that none of the LE samples affected potassium currents in Kvl-transfected HEK-293 cells. These data suggest that 'anti-VOKC' antibodies may not bind directly to Kv1.111.2/1.6 homomers, or to a range of Kv1.I/1.2/1.6 subunit-containing heteromers in transfected cells. The findings instead suggest that 'anti-VOKC' antibodies in LE patient plasma may bind to a Kvl-associated protein that contributes to a-DTX-sensitive complexes in the radioimmunoprecipitation assay, but is absent from Kv1.111.2/1.6-transfected cells. Future work to characterise whether another antigen is bound by LE patient anti-VOKC antibodies will be important in determining how these antibodies contribute to the pathogenesis of LE.

Abstract:
The ion flow in nanochannels is investigated by using nanochannels in an open configuration that allows the direct observation of fluid diffusion through an optical microscope. An “open nanochannel” is a channel with the top open to air such that fluidics can be introduced from both the entrance and the top of the channels. The experimental results showed that the diffusion length of the potassium chloride and phosphate buffer decreased with their concentration. The observed behaviors were analyzed by the contact angle variation due to the electrowetting phenomena involving the interaction between electrical double layer and counter-ions in the solution.

Abstract:
The swelling of plant motor cells is regulated by various signals with almost unknown mediators. One of the obligatory steps in the signaling cascade is the activation of K+-influx channels -K+ channels activated by hyperpolarization (KH channels). We thus explored the regulation of these channels in our model system, motor cell protoplasts from Samanea saman, using patch-clamp in the "whole cell" configuration. (a) The most novel finding was that the activity of KH channels in situ varied with the time of the day, in positive correlation with cell swelling: in Extensor cells KH channels were active in the earlier part of the day, while in Flexor cells only during the later part of the day; (b) High internal pH promoted the activity of these channels in Extensor cells, opposite to the behavior of the equivalent channels in guard cells, but in conformity with the predicted behavior of the putative KH channel, cloned from S. saman recently; (c) HIgh external K+ concentration increased (KH channel currents in Flexor cells. BL depolarized the Flexor cells, as detected in cell-attached patch-clamp recording, using KD channels (the K+-efflux channels) as "voltage-sensing devices". Subsequent Red-Light (RL) pulse followed by Darkness, hyperpolarized the cell. We attribute these changes to the inhibition of the H+-pump by BL and its reactivation by RL, as they were abolished by an H+-pump inhibitor. BL increased also the activity KD channels, in a voltage-independent manner - in all probability by an independent signaling pathway. Blue-Light (BL), which stimulates shrinking of Flexor cells, evoked the IP3 signaling cascade (detected directly by IP3 binding assay), known to mobilize cytosolic Ca2+. Nevertheless, cytosolic Ca2+ . did not activate the KD channel in excised, inside-out patches. In this study we established a close functional similarity of the KD channels between Flexor and Extensior cells. Thus the differences in their responses must stem from different links to signaling in both cell types.
