Potential therapeutic targeting of BKCa channels in glioblastoma treatment

Molecular Oncology, EarlyView.
This review summarizes current insights into the role of BKCa and mitoBKCa channels in glioblastoma biology, their potential classification as oncochannels, and the emerging pharmacological strategies targeting these channels, emphasizing the translational challenges in developing BKCa‐directed therapies for glioblastoma treatment.

Proton block and voltage gating are potassium-dependent in the cardiac leak channel Kcnk3. [PDF]

, 2000
Potassium leak conductances were recently revealed to exist as independent molecular entities. Here, the genomic structure, cardiac localization, and biophysical properties of a murine example are considered.

Exploiting metabolic adaptations to overcome dabrafenib treatment resistance in melanoma cells

Molecular Oncology, EarlyView.
We show that dabrafenib‐resistant melanoma cells undergo mitochondrial remodeling, leading to elevated respiration and ROS production balanced by stronger antioxidant defenses. This altered redox state promotes survival despite mitochondrial damage but renders resistant cells highly vulnerable to ROS‐inducing compounds such as PEITC, highlighting redox

Scorpion toxins targeting Kv1.3 channels: insights into immunosuppression

Journal of Venomous Animals and Toxins including Tropical Diseases, 2019
Scorpion venoms are natural sources of molecules that have, in addition to their toxic function, potential therapeutic applications. In this source the neurotoxins can be found especially those that act on potassium channels.

HSP70 governs permeability and mechanotransduction in primary human endothelial cells

FEBS Open Bio, EarlyView.
HSP70 chemical inhibition reduces endothelial cell proliferation and increases permeability, the latter supported by normal interendothelial junctional protein distribution. HSP70 also plays a role in shear stress response, a hemodynamic force naturally present in blood vessels and correlated with vessel protection.

Ultrasound Stimulation Modulates Voltage-Gated Potassium Currents Associated With Action Potential Shape in Hippocampal CA1 Pyramidal Neurons

Frontiers in Pharmacology, 2019
Potassium channels (K+) play an important role in the regulation of cellular signaling. Dysfunction of potassium channels is associated with several severe ion channels diseases, such as long QT syndrome, episodic ataxia and epilepsy.

Block of Kcnk3 by protons. Evidence that 2-P-domain potassium channel subunits function as homodimers. [PDF]

, 2001
KCNK subunits have two pore-forming P domains and four predicted transmembrane segments. To assess the number of subunits in each pore, we studied external proton block of Kcnk3, a subunit prominent in rodent heart and brain.

Sodium leak through K2P potassium channels and cardiac arrhythmia, an emerging theme. [PDF]

, 2017
In this issue of EMBO Molecular Medicine, Decher et al (2017) identify a point mutation in the K2P2 (TREK‐1) potassium (K+) channel that changes function in just those ways expected to predispose to right ventricular outflow tract (RVOT) ventricular

Clinical Practice Guideline for Evaluation and Management of Peripheral Nervous System Manifestations in Sjögren's Disease

Arthritis Care &Research, Accepted Article.
Objectives Sjögren's disease is an autoimmune disorder that can impact multiple organ systems, including the peripheral nervous system (PNS). PNS manifestations, which can exist concurrently, include mononeuropathies, polyneuropathies, and autonomic nervous system neuropathies. To help patients and providers in the decision‐making process, we developed
