Potential roles of voltage-gated ion channel disruption in Tuberous Sclerosis Complex

Frontiers in Molecular Neuroscience
Tuberous Sclerosis Complex (TSC) is a lynchpin disorder, as it results in overactive mammalian target of rapamycin (mTOR) signaling, which has been implicated in a multitude of disease states.

Analysis of a putative voltage‐gated prokaryotic potassium channel [PDF]

European Journal of Biochemistry, 2001
Most of the completely sequenced prokaryotic genomes contain genes of potassium channel homologues, but there is still not much known about the role of these proteins in prokaryotes. Here we describe the large‐scale overproduction and purification of a prokaryotic voltage‐gated potassium channel homologue, Kch, from Escherichia coli.

Electrically Readable Lateral Flow Assay Using Organic Transistors for Diagnostic Applications

Advanced Materials, EarlyView.
Electrolyte‐gated organic field‐effect transistors (EGOFETs) are integrated with lateral flow (LF) paper fluidics to create a reusable, portable, and low‐cost point‐of‐care (PoC) diagnostic test. The devices are validated for Human Immunoglobulin G detection, achieving high sensitivity (0.1 fm), selectivity, and reproducibility with rapid results in 20–

MECHANISMS OF DISEASE Acute Oxygen-Sensing Mechanisms [PDF]

, 2005
JOSEPH PRIESTLEY, ONE OF THE THREE SCIENTISTS CREDITED WITH THE discovery of oxygen, described the death of mice that were deprived of oxygen. However, he was also well aware of the toxicity of too much oxygen, stating, “For as a candle burns much faster

A nongenomic mechanism for progesterone-mediated immunosuppression: Inhibition of K+ channels, Ca2+ signaling, and gene expression in T lymphocytes [PDF]

, 1998
The mechanism by which progesterone causes localized suppression of the immune response during pregnancy has remained elusive. Using human T lymphocytes and T cell lines, we show that progesterone, at concentrations found in the placenta, rapidly and ...

Opposite effects of the S4-S5 linker and PIP2 on voltage-gated channel function: KCNQ1/KCNE1 and other channels

Frontiers in Pharmacology, 2012
Voltage-gated potassium (Kv) channels are tetramers, each subunit presenting six transmembrane segments (S1-S6), with each S1-S4 segments forming a voltage-sensing domain (VSD) and the four S5-S6 forming both the conduction pathway and its gate.

K2P channels and their protein partners. [PDF]

, 2005
A decade since their discovery, the K2P channels are recognized as pathways dedicated to regulated background leakage of potassium ions that serve to control neuronal excitability. The recent identification of protein partners that directly interact with

Intrinsic Gating Properties of a Cloned G Protein-activated Inward Rectifier K^+ Channel [PDF]

, 1995
The voltage-, time-, and K^+-dependent properties of a G protein-activated inwardly rectifying K^+ channel (GIRK1/KGA/Kir3.1) cloned from rat atrium were studied in Xenopus oocytes under two-electrode voltage clamp. During maintained G protein activation
