Regulation of Adenosine-activated GIRK Channels by Gq-coupled Receptors in Mouse Atrial Myocytes
HanaCho 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 6 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2010, Vol.14 No.3 5 145-150 (6 pages)
Adenosine (Ado) is an important mediator of the endogenous defense against ischemia-induced injury in the heart. The action of Ado is mediated by activation of G protein-gated inwardly rectifying K＋ (GIRK) channels. In turn, GIRK channels are inhibited by reducing phosphatidylinositol 4,5-bisphosphate (PIP2) through Gq protein-coupled receptors (GqPCRs). We previously found that GIRK channels activated by acetylcholine, a muscarinic M2 acetylcholine receptor agonist, are inhibited by GqPCRs in... -

We explore the question of whether adenosine 5'-triphosphate (ATP) acts as an excitatory neurotransmitter in guinea-pig gastric smooth muscle. In an organ bath system, isometric force of the circular smooth muscle of guinea-pig gastric antrum was measured in the presence of atropine and guanethidine. Under electrical field stimulation (EFS) at high frequencies (＞20 Hz), NO-mediated relaxation during EFS was followed by a strong contraction after the cessation of EFS (a... -

still continues. To investigate the effect of adenosine on Cl secretion and its underlying mechanism in the rabbit colon mucosa, we measured short circuit current (ISC) under automatic voltage clamp with DVC-1000 in a modified Ussing chamber. Adenosine, when added to the basolateral side of the muocsa, increased ISC in a dose-dependent manner. The adenosine-stimulated ISC response was abolished when Cl in the bath solution was replaced completely with gluconate. In addition, the IS... -

is concerned, CBZ acts as an antagonist. However, the situation with regard to A1 receptors is less straightforward. In this study, we describe the effects of one-week CBZ treatment (25 mg/kg/day) on cerebrocortical A1 adenosine receptors. A1 adenosine receptor bindings as determined by using [3H]DPCPX was not significantly altered in membranes prepared from CBZ-treated rats. However, there was a significant decrease in the A1 adenosine receptor-mediated stimulation of [35S]GTPγS binding to... -

myocardial contracture in the ischemic-reperfused heart and reduced the release of lactate dehydrogenase during the reperfusion period. Polymyxin B, chelerythrine and colchicine, PKC inhibitors, attenuated almost completely the anti-ischemic effect of IP, while adenosine receptor antagonists did not. These results indicate that PKC may be a crucial intracellular mediator in anti-ischemic action of IP in ischemic-reperfused rat heart, while adenosine may not be involved in the mechanism of IP. -

fMLP에 의해 자극된 중성호성 백혈구에서의 superoxide 생성, 탈과립과 세포내 칼슘 동원과 백혈구 부착은 adenosine 수용체에 의하여 조절된다고 추정된다. Adenosine은 protein kinase C의 활성화에 따른 백혈구 반응의 자극에 영향을 나타내지 않을 것으로 시사된다. Nonprimed 세포에 비하여, lipopolysaccharide-primed 중성호성 백혈구에서 fMLP에 의한 superoxide 생성은 adenosine의 영향을 적게 받을 것으로 여겨진다. Adenosine 존재하에서 백혈구 반응에 나타내는 theophylline의 억제효과는 세포내 cAMP 축적에 기인할 것으로... -

A2-흥분약인 CGS 21680C는 [3H]-ACh 유리에 별다른 영향을 미치지 못하였다. 한편 관류액내의 magnesium 농도를 변화시켰을때 magnesium 그 자체로는 [3H]-ACh 유리에 별다른 변화가 없었으며, magnesium을 4 mM로 증가시켰을때 adenosine의 효과가 크게 강화되어 용량 반응 곡선이 좌측으로 이동됨을 볼 수 있었다. 이상의 실험 결과로 adenosine은 흰쥐 해마의 choline 작동성 신경에 presynaptic A1-adenosine heteroreceptor를 통하여 ACh 유리 감소를 일으키며, 이러한 adenosine 작용은 magnesium이온에 의존적임을 알 수 있었다. -

활성도에 영향을 주지 않았다. ATP 또는 adenosine에 의한 superoxide 라디칼 생성의 변경은 다른 triphosphate nucleotide나 nucleoside에 의한 것보다 현저하였다. 활성화된 중성 백혈구에서 ATP와 ADP는 칼슘이온의 흡수를 더 자극하였고 세포질 유리 칼슘농도를 증가시켰으나, adenosine은 칼슘이온의 이동을 억제하였다. APT에 의한 세포질 유리 칼슘이온 농도의 증가는 verapamil에 의하여 효과적으로, tetrodotoxin에 의하여 약간 억제되었다. ATP에 노출된 활성화된 중성 백혈구에서의 superoxide 라디칼 생성에 대한 verapamil... -

adenosine A2 receptor agonist, (20μg /Kg) and NECA, nonspecific adenosine receptor agonist, (20μg /Kg) inhibited the responses of WDR cells to pinch and C fiber stimulation more strongly than those to brush and A fiber stimulation. CPCA (i.v.) also suppressed the responses of WDR cells to thermal stimulus. And all the CPCA-induced inhibitions were caffeine-reversible. When CPCA was directly applied onto the spinal cord or intravenously administered into the spinal cat, on average, about three... -

activity. In an outside-out patch with intrapipette GTP and ATP, external adenosine stimulated KATP channel activity. In an inside-out Patch with intrapipette adenosine, ATP reduced KATP channel activity, and GTP stimulated KATP channel activity. Adenosine receptor activation shifted the half-maximal inhibition Of KATP channel from 70 to 241 μm. These results Suggest that activation of adenosine receptors stimulates KATP channels in rabbit ventricular myocytes by reducing the apparent affinity... -

of adenosine 5 -tetraphosphate were measured during incubation of platelets in whole blood, erythrocyte suspension and plasma, respectively. The results suggest that plasma contributes more than blood cells to the catabolism of adenosine 5 -tetraphosphate. The pattern of degradation indicates that ATPP may be degraded mainly to AMP by soluble enzymes in plasma and very slowly to ADP and/or AMP by ectoenzymes on blood cells such as erythrocyte. The nature of the enzymes responsible fer the... -

of extracellular of Ca2+ were decreased by lowering pHo and were increased by elevating pHo. High K+ (25mM) induced contraction at pH 6.8 was not returned to the level of the contraction at pH 7.4 by the elevation of extracellular. calcium [Ca2+]o. Adenosine-induced relaxation was more significant with 5% CO2 than 0% CO2 in the high K+-induced contraction and was more significant with low pHo than high pHo in the contraction induced by EFS. From the above results, it is suggested that H+ and CO2... -
