Expression and function of ATP-dependent potassium channels in zebrafish islet β-cells [PDF]

Royal Society Open Science, 2017
ATP-sensitive potassium channels (KATP channels) are critical nutrient sensors in many mammalian tissues. In the pancreas, KATP channels are essential for coupling glucose metabolism to insulin secretion.

K(ATP) channel gene expression is induced by urocortin and mediates its cardioprotective effect

, 2002
Background— Urocortin is a novel cardioprotective agent that can protect cardiac myocytes from the damaging effects of ischemia/reperfusion both in culture and in the intact heart and is effective when given at reperfusion.

Omega-3 polyunsaturated fatty acid-induced vasodilation in mouse aorta and mesenteric arteries is not mediated by ATP-sensitive potassium channels

Frontiers in Physiology, 2022
There is strong evidence that the omega-3 polyunsaturated fatty acids (n-3 PUFAs) docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) have cardioprotective effects.

Gβγ subunit activation of KV7 and BKCa channels underlies calcitonin gene‐related peptide vasorelaxation in myogenic rat coronary resistance arteries

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose CGRP is a potent, clinically relevant coronary vasodilator known to play a role in cardioprotection. Here, we investigated the precise intracellular signalling pathways leading to vasodilation in small coronary arteries.

Photobiomodulation on KATP Channels of Kir6.2-Transfected HEK-293 Cells

International Journal of Photoenergy, 2014
Background and Objective. ATP-sensitive potassium (KATP) channel couples cell metabolism to excitability. To explore role of KATP channels in cellular photobiomodulation, we designed experiment to study effect of low intensity 808 nm laser irradiation on

Cardiac remodelling in type 2 diabetes: Pathophysiological mechanisms and opportunities for multiscale computational modelling and simulation

The Journal of Physiology, EarlyView.
Abstract figure legend Overview of multiscale cardiac remodelling in type 2 diabetes and how to model and simulate these changes using a human‐based, multiscale computational framework. Cardiac remodelling in type 2 diabetes occurs at ionic channel, protein, cellular, tissue and whole‐organ level, affecting the electrophysiological function, mechanical

New insights into KATP channel gene mutations and neonatal diabetes mellitus [PDF]

, 2020
The ATP-sensitive potassium channel (KATP channel) couples blood levels of glucose to insulin secretion from pancreatic β-cells. KATP channel closure triggers a cascade of events that results in insulin release.
