Insulin stimulates glucose transport in muscle and fat cells by promoting the translocation of glucose transporter (GLUT4) to the cell surface. Phosphatidylinositide 3-kinase (PI3-kinase) has been implicated in this process. However, the involvement of protein kinase B (PKB)/Akt and PKC-ζ, those are known as the downstream target of PI3-kinase in regulation of GLUT4 translocation, is not known yet. An interesting possibility is that these protein kinases phosphorylate GLUT4 directly in this...

The aim of this study was to clarify the mechanism of the inhibitory action of carbon monoxide (CO) on contraction, by measuring cytosolic Ca2⁢ level ([Ca2⁢]i) and ionic currents in guinea-pig ileum. CO (10%) inhibited 40 mM KCl-induced contraction and this effect was blocked by ODQ (1μM), a soluble guanylyl cyclase (sGC) inhibitor. CO inhibited the 40 mM KCl-induced contraction without changing [Ca2⁢]i. Cumulative addition of KCl induced a graded increase in [Ca2⁢]i...

In the rabbit renal artery, acetylcholine (ACh, 1 nM∼10μM) induced endothelium-dependent relaxation of arterial rings precontracted with norepinephrine (NE, 1μM) in a dose-dependent manner. NG-nitro- L-arginine (L-NAME, 0.1 mM), an inhibitor of NO synthase, or ODQ (1μM), a soluble guanylate cyclase inhibitor, partially inhibited the ACh-induced endothelium-dependent relaxation. The ACh-induced relaxation was abolished in the presence of 25 mM KCl and L-NAME. The cytochrome P450 inhibitors,...

The present investigation tested the hypothesis that the activation of protein kinase G (PKG) leads to a phosphorylation of Ca2⁢-activated potassium channel (KCa channel) and is involved in the activation of KCa channel activity in cerebral arterial smooth muscle cells of the rabbit. Single-channel currents were recorded in cell-attached and inside-out patch configurations of patch-clamp techniques. Both molsidomine derivative 3-morpholinosydnonimine-N-ethylcarbamide (SIN-1, 50μM) and...

in response to mechanical stretch and atrial compliance, experiments have been done in perfused nonbeating rabbit atria with different ages: 1-day, 1-, 2-, 3-, 4-, and 8-wk-old. In 1-day-old-rabbits, an increase in intraatrial pressure resulted in an increase in atrial volume, which was higher than that in 1-wk-old rabbits. Increases in atrial volume stimulated the secretion of ANP with concomitant translocation of extracellular fluid (ECF) into the atrial lumen. However, mechanically stimulated...

This study was undertaken to investigate an involvement of nitroxergic innervation in gastric smooth muscle of rat. Isometric tension study, the measurement of single cell length, NADPH diaphorase stain of smooth muscle layers and neuronal nitric oxide synthase (nNOS) western blotting were performed. Sodium nitroprusside (SNP), a nitric oxide donor, relaxed the muscle strips precontracted by acetylcholine (ACh) in a concentration-dependent manner. Pretreatment of L-arginine decreased the...

filters, and investigated distribution of the P2Y receptors by analyzing nucleotide-induced short circuit current (Isc) responses. Exposure to different nucleotides of either the apical or basolateral surface of cell monolayers stimulated Isc. Dose-response relationship and cross-desensitization studies suggested that at least 3 distinct P2Y receptors are expressed asymmetrically on the apical and basolateral membranes. A P2Y2-like receptor, which responds to UTP and ATP, is expressed on both t...

The purpose of our investigation was to examine the effects of prostaglandin F2α (PGF2α) on membrane potentials, Ca2⁢-activated K⁢ (KCa) channels, and delayed rectifier K⁢ (KV) channels using the patch-clamp technique in single rabbit middle cerebral arterial smooth muscle cells. PGF2α significantly hyperpolarized membrane potentials and increased outward whole-cell K⁢ currents. PGF2α increased open-state probability of KCa channels without the change of the open and...

Natriuretic peptides comprise a family of three structurally related peptides; atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), and C-type natriuretic peptide (CNP). The present study was performed to investigate the effect of ANP on the proliferation and activity of ROS17/2.8 and HOS cells which are well-characterized osteoblastic cell lines. ANP dose-dependently decreased the number of ROS17/2.8 and HOS cells after 48-hour treatment. ANP generally increased the alkaline...

Cholecystokinin (CCK) is a gastrointestinal hormone which plays an important role in satiety and gastric motility. It is also widely distributed throughout the central nervous system, where it appears to be involved in the central control of anxiety, feeding behavior and nociception. Two distinct CCK receptor types, CCKA and CCKB, have been found in the brain. Both CCK receptors coexist in the rat nucleus tractus solitarius (NTS), which is the primary center for the coordination of peripheral...
