Lysophosphatidylcholine and Cellular Potassium Loss in Isolated Rabbit Ventricle.

Journal of cardiovascular pharmacology and therapeutics

Goldhaber JI, Deutsch N, Alexander LD, Weiss JN.
PMID: 10684479
J Cardiovasc Pharmacol Ther. 1998 Jan;3(1):37-42. doi: 10.1177/107424849800300105.

BACKGROUND: Lysophospholipids such as lysophosphatidylcholine (LPC) have many direct electrophysiological effects on cardiac muscle and have been implicated as a cause of lethal ventricular arrhythmias during acute myocardial ischemia. Because extracellular K(+) accumulation is also a key arrhythmogenic factor...

Potassium channel activators decrease endogenous glutamate release from rat cerebellar slices.

Dickie BG, Davies JA.
PMID: 24186325
Amino Acids. 1995 Jun;8(2):159-69. doi: 10.1007/BF00806489.

The effects of the sulphonylurea activators of ATP-sensitive potassium channels (K(+) ATP), cromakalim and pinacidil, on the evoked-release of endogenous glutamate from superfused slices of rat cerebellum was examined. K(+)-stimulated release was Ca(2+)-dependent, whereas tetrapentylammonium (TPeA)-evoked release occurred both...

Effects of aging on ATP sensitive K(+) channels and on prostanoid production in the rat mesenteric bed.

Age

Feleder EC, Peredo HA, Mendizábal VE, Adler-Graschinsky E.
PMID: 23604379
Age (Omaha). 1998 Oct;21(4):183-8. doi: 10.1007/s11357-998-0027-3.

The aim of the present work was to evaluate, in the rat isolated mesenteric bed, whether increasing age is associated with alterations in the ATP sensitive K(+) channels functionality. Moreover, studies were performed in order to evaluate the effects...

Role of the Inward K Rectifier in the Repetitive Activity at the Depolarized Level in Single Ventricular Myocytes.

Journal of biomedical science

Vassalle M, Valenzuela F.
PMID: 11725024
J Biomed Sci. 1994 Jun;1(3):179-192. doi: 10.1007/BF02253348.

The role of the inward K(+) rectifier in the repetitive activity at depolarized levels was studied in guinea pig single ventricular myocytes by voltage- and current-clamp methods. In action potentials arrested at the plateau by a depolarizing current, small...

Role of potassium channels in stretch-promoted atrial natriuretic factor secretion.

Journal of the American Society of Hypertension : JASH

Ogawa T, Forero M, Burgon PG, Kuroski de Bold ML, Georgalis T, de Bold AJ.
PMID: 20409940
J Am Soc Hypertens. 2009 Jan-Feb;3(1):9-18. doi: 10.1016/j.jash.2008.07.002. Epub 2008 Oct 31.

The cardiac polypeptide hormone atrial natriuretic factor (ANF) plays important roles in the regulation of blood volume and pressure. Few specific details are known about basal or stretch-promoted ANF secretion. Here, we investigated the involvement of K(+) channels in...

Inhibitory effects of the ATP-sensitive potassium channel openers cromakalim, pinacidil and minoxidil on the carbachol-response curve in porcine detrusor muscle.

Arab journal of urology

Badawi JK, Kirschner-Hermanns R, Ding A.
PMID: 26558027
Arab J Urol. 2012 Jun;10(2):207-15. doi: 10.1016/j.aju.2011.12.009. Epub 2012 Mar 03.

AIMS: ATP-sensitive potassium channels represent promising drug targets for treating specific bladder diseases. The inhibitory effects of ATP-selective potassium channel openers (PCOs) on the carbachol-response curve in porcine detrusor muscle were examined.MATERIALS AND METHODS: Each of the three substances...

Opening of ATP sensitive potassium channels causes migraine attacks with aura.

Brain : a journal of neurology

Al-Karagholi MA, Ghanizada H, Nielsen CAW, Hougaard A, Ashina M.
PMID: 33768245
Brain. 2021 Sep 04;144(8):2322-2332. doi: 10.1093/brain/awab136.

Migraine afflicts more than one billion individuals worldwide and is a leading cause of years lived with disability. In about a third of individuals with migraine aura occur in relation to migraine headache. The common pathophysiological mechanisms underlying migraine...

The Effect of Cromakalim on the Hindlimb Vascular Bed of the Male Rat: Do Glybenclamide and/or Nitric Oxide Modulate the Vasodilation?.

American journal of therapeutics

Jahr JS, Feng CJ, Wang J, Holton R, Cheng DY.
PMID: 11835061
Am J Ther. 1994 Jun;1(1):8-14. doi: 10.1097/00045391-199406000-00003.

Cromakalim, a benzopyran derivative, is a member of a novel class of antihypertensive agents that increase membrane K(+) conductance through ATP-sensitive K(+) channels. The effects of glybenclamide and N(omega)-L-arginine methyl ester (L-NAME), a specific inhibitor of nitric oxide synthesis...

Mechanism of Vasorelaxation Caused by N-Benzylsecoboldine in Rat Thoracic Aorta.

Journal of biomedical science

Teng CM, Yu SM, Pan CP, Lee SS.
PMID: 11725007

The vasorelaxing effect of N-benzylsecoboldine on the rat thoracic aorta was investigated, and we also compare it with nifedipine and cromakalim. In high K(+) (60 mM) medium, Ca(2+) (0.03-3 mM)-induced vasoconstriction was inhibited concentration-dependently by N-benzylsecoboldine, whereas this contraction...
