Brain glucosensing and the KATP channel
Nature Neuroscience, 2001An ATP-sensitive K+ channel in glucose-responsive neurons is shown to be required for the emergency response to severe glucose deprivation, but not necessarily for normal feeding.

The Pharmacology of ATP-Sensitive K+ Channels (KATP)
2021ATP-sensitive K+ channels (KATP) are inwardly-rectifying potassium channels, broadly expressed throughout the body. KATP is regulated by adenine nucleotides, characteristically being activated by falling ATP and rising ADP levels thus playing an important physiological role by coupling cellular metabolism with membrane excitability.

The substantia nigra pars reticulata, the area with the highest expression of ATP-sensitive potassium channels in the brain, plays a pivotal role in suppressing the propagation of generalized seizures by its silence. Mice lacking the Kir6.2 subunit of the channels were extremely susceptible to generalized seizures after brief hypoxia. The nigral neuron

Bepridil, which is clinically useful in the treatment of arrhythmias, has been reported to inhibit sarcolemmal ATP-sensitive K(+) (sarcK(ATP)) channels. However, the effect of bepridil on mitochondrial ATP-sensitive K(+) (mitoK(ATP)) channels remains unclear.

Clinical Exploitation of the KATP Channel
1995Potassium ion (K+) channels play a dominant role in controlling the resting membrane potential of excitable cells. They are ubiquitous, structurally diverse and functionally are perhaps most usefully classified by what causes them to open or close.

ATP-sensitive potassium channels (KATP channels) provide a mechanism for linking membrane potassium permeability to cellular metabolism. They have important functions in the tissues of central importance to this book, cardiac muscle and systemic and coronary vascular smooth muscle.

Vascular Pathology and The KATP Channel
1995K+ channels determine the resting membrane potential and cellular excitability of most cells [1], The opening of K+ channels shifts the membrane potential towards the K+ equilibrium potential which is around -90 mV. In excitable cells endowed with depolarization-activated Ca2+ channels (voltage-gated Ca2+ channels, VOCCs), hyperpolarization will ...

KATP channels and basal coronary vascular tone
Cardiovascular Research, 1994After reviewing recent experimental work from various laboratories we have come to the following conclusions. (1) An increase in transmural pressure causes depolarisation of coronary arterioles, which increases smooth muscle tone. Under these conditions the opening of KATP channels can induce a much larger change in membrane potential than in relaxed ...

Imaging and Quantification of Recycled KATP Channels
2013This chapter describes immunochemistry-based methods to investigate recycling of membrane proteins at the cell surface. Two methods are described, one qualitative and the other quantitative. Both methods consist of two rounds of extracellular antibody capture.

The KATP Channel and the Sulfonylurea Receptor
2001ATP-sensitive K+ channels (KAgp channels) were first described in cardiac myocytes (1) and were subsequently found in many other tissues including pancreatic 13-cells (25), skeletal muscle (6), smooth muscle (7), brain (8), pituitary (9), and kidney (10) and in mitochondria (11).
