Mechanical effects on KATP channel gating in rat ventricular myocytes.
PLoS ONE, 2013 Cardiac KATP channels link metabolism with electrical activity. They are implicated in arrhythmias, secretion of atrial natriuretic peptide and protection of the heart from hypertrophy and failure. These processes may involve mechanosensitivity.

The Antidiabetic Potential of Alpha‐Mangostin: A Review of Preclinical and Clinical Evidence
AgriFood: Journal of Agricultural Products for Food, Volume 2, Issue 3, Page 262-284, September 2026.Alpha‐mangostin is a compound from the pericarp of Garcinia mangostana. The antidiabetic effects of alpha‐mangostin include enhancing insulin secretion, improving glucose uptake through GLUT receptor upregulation, reducing oxidative stress and inflammation, promoting wound healing, reducing HbA1C, reducing HOMA‐IR index, and decreased mRNA expressions ...

Molecular determinants of KATP channel inhibition by ATP [PDF]
The EMBO Journal, 1998 ATP-sensitive K+ (KATP) channels are both inhibited and activated by intracellular nucleotides, such as ATP and ADP. The inhibitory effects of nucleotides are mediated via the pore-forming subunit, Kir6.2, whereas the potentiatory effects are conferred by the sulfonylurea receptor subunit, SUR.

Alzheimer's &Dementia, Volume 22, Issue 9, September 2026.Abstract Early disruption of gamma oscillations is increasingly recognized as a contributor to neurodegeneration and cognitive decline in Alzheimer's disease (AD), positioning 40‐Hz stimulation as a promising neuromodulatory strategy. However, its neurophysiological and cognitive effects remain highly variable across studies, underscoring the need for ...

Sulfonylurea and K+-Channel Opener Sensitivity of KATP Channels [PDF]
The Journal of General Physiology, 1999 The sensitivity of KATP channels to high-affinity block by sulfonylureas and to stimulation by K+ channel openers and MgADP (PCOs) is conferred by the regulatory sulfonylurea receptor (SUR) subunit, whereas ATP inhibits the channel through interaction with the inward rectifier (Kir6.2) subunit.

Do anionic phospholipids serve as cofactors or second messengers for the regulation of activity of cloned ATP-sensitive K+ channels? [PDF]
, 2003 The regulation of ion channels by anionic phospholipids is currently very topical. An outstanding issue is whether phosphatidylinositol 4,5-diphosphate and related species act as true second messengers in signaling or behave in a manner analogous to an ...

Infarct size limitation by nicorandil Roles of mitochondrial KATP channels, sarcolemmal KATP channels, and protein kinase C [PDF]
, 2002 ObjectivesThis study aimed to examine: 1) whether nicorandil protects the ischemic myocardium by activating sarcolemmal adenosine triphosphate (ATP)-sensitive K+ (sarcKATP) channels or the mitochondrial KATP (mitoKATP) channels, and 2) whether protein ...

BRET‐Based Approaches for Ion Channels: Emerging Applications and Future Directions
Archiv der Pharmazie, Volume 359, Issue 9, September 2026.Bioluminescence resonance energy transfer (BRET) is a versatile method for studying ligand–protein interactions. Its compatibility with high‐throughput screening and real‐time kinetics has made it widely used in drug discovery. Here, we summarize recent applications of BRET‐based methods for studying ligand binding to ion channels, highlighting key ...

Glimepiride, a novel sulfonylurea, does not abolish myocardial protection afforded by either ischemic preconditioning or diazoxide [PDF]
, 2001 Background: The sulfonylurea glibenclamide (Glib) abolishes the cardioprotective effect of ischemic preconditioning (IP), presumably by inhibiting mitochondrial KATP channel opening in myocytes. Glimepiride (Glim) is a new sulfonylurea reported to affect

Ecography, Volume 2026, Issue 9, September 2026.The Pan‐Himalayan region harbors exceptional biodiversity, yet the origins and underlying mechanisms driving this remarkable diversity remain poorly understood, especially among species‐rich invertebrates. Pimoa spiders exhibit an intercontinental disjunct distribution across three major mountain regions: the Rockies, the Alps, and the Pan‐Himalaya ...
