Repurposing Kir6/SUR2 Channel Activator Minoxidil to Arrests Growth of Gynecologic Cancers

open access: yesFrontiers in Pharmacology, 2020
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

open access: yeseLife, 2019
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]

open access: yesThe Journal of General Physiology, 1997
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.

Insulin down-regulates cardioprotective SUR2A in the heart-derived H9c2 cells: A possible explanation for some adverse effects of insulin therapy

open access: yesBiochemistry and Biophysics Reports, 2018
Some recent studies associated insulin therapy with negative cardiovascular events and shorter lifespan. SUR2A, a KATP channel subunit, regulate cardioprotection and cardiac ageing.

The Role and Therapeutic Potential of Voltage‐Gated Potassium Channel Kv1.3 in Metabolism‐Related Disorders

open access: yesiNew Medicine, Volume 2, Issue 2, June 2026.
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]

open access: yesJournal of Biological Chemistry, 2002
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]

open access: yesPLoS ONE, 2011
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 ...

Modulation of KATP channels by diazoxide preserves mitochondrial function and barrier integrity under staurosporine‐induced epithelial stress

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 12, Page 3213-3233, June 2026.
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]

open access: yes, 2014
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

open access: yes, 2021
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 ...
