Repurposing Kir6/SUR2 Channel Activator Minoxidil to Arrests Growth of Gynecologic Cancers
Gynecologic cancers are among the most lethal cancers found in women, and, advanced stage cancers are still a treatment challenge. Ion channels are known to contribute to cellular homeostasis in all cells and mounting evidence indicates that ion channels

Mechanism of pharmacochaperoning in a mammalian KATP channel revealed by cryo-EM
ATP-sensitive potassium (KATP) channels composed of a pore-forming Kir6.2 potassium channel and a regulatory ABC transporter sulfonylurea receptor 1 (SUR1) regulate insulin secretion in pancreatic β-cells to maintain glucose homeostasis.

Control of Rectification and Gating of Cloned KATP Channels by the Kir6.2 Subunit [PDF]
KATP channels are a functional complex of sulphonylurea receptor (SUR1, SUR2) and inward rectifier K+ (Kir6.1, Kir6.2) channel subunits. We have studied the role of the putative pore forming subunit (Kir6.2) in regulation of rectification and gating of KATP channels generated by transfection of SUR1 and Kir6.2 cDNAs in COSm6 cells.

ABSTRACT Over the past three decades, the global burden of common metabolic diseases such as obesity, diabetes, and atherosclerosis has steadily increased, becoming a serious public health issue that poses a major threat to human health worldwide. Potassium channels, particularly the voltage‐gated Kv1.3 subtype, serve as critical regulators of cellular

Cytoplasmic Vestibule of the Weak Inward Rectifier Kir6.2 Potassium Channel [PDF]
Intracellular application of certain charged methanethiosulfonate (MTS) reagents modified and irreversibly inhibited Kir6.2 channels when cysteine substitutions were introduced at positions Ile-210, Ile-211, or Ser-212 within the putative cytoplasmic region. Inhibition depends on the spatial dimensions of the MTS reagents.

Activation of cGMP-dependent protein kinase stimulates cardiac ATP-sensitive potassium channels via a ROS/calmodulin/CaMKII signaling cascade. [PDF]
Cyclic GMP (cGMP)-dependent protein kinase (PKG) is recognized as an important signaling component in diverse cell types. PKG may influence the function of cardiac ATP-sensitive potassium (K(ATP)) channels, an ion channel critical for stress adaptation ...

Background and Purpose Intestinal barrier dysfunction caused by mitochondrial stress, oxidative damage and apoptosis, are hallmarks of dysbiosis‐associated gastrointestinal (GI) disorders. Staurosporine causes downstream features of dysbiosis‐induced epithelial damage.

Age-dependent changes in the exocytotic efficacy in Kir6.2 ablated mouse pancreatic beta cells [PDF]
ATP-sensitive K+ channels (K channels) regulate cellular energy metabolism in control of membrane excitability. The KATP channel of pancreatic β-cells is composed of SUR1 and Kir6.2 subunits. Kir6.2-/- mice have a defective KATP channel and can mimic the

DataSheet1_Simulating PIP2-Induced Gating Transitions in Kir6.2 Channels.PDF
ATP-sensitive potassium (KATP) channels consist of an inwardly rectifying K+ channel (Kir6.2) pore, to which four ATP-sensitive sulfonylurea receptor (SUR) domains are attached, thereby coupling K+ permeation directly to the metabolic state of the cell ...
