The prostate gland contains numerous neuroendocrine cells that are believed to influence the function of the prostate gland. Our recent study demonstrated the expression of both α1- and α2-ARs, signaling the release of stored Ca2⁢ and the inhibition of N-type Ca2⁢ channels, respectively, in rat prostate neuroendocrine cells (RPNECs). In this study, the effects of NA on the resting membrane potential (RMP) of RPNECs were investigated using a whole-cell patch clamp method. Fresh...

The induction of interleukin-6 (IL-6) using combined proinflammatory agents (LPS/IFN-γ or TNF-α/ IFN-γ) was studied in relation to p38 mitogen-activated protein kinase (MAPK) and NF-κB transcriptional factor in primary neonatal cardiomyocytes. When added to cultures of cardiomyocytes, the combined agents (LPS/IFN-γ or TNF-α/IFN-γ) had stimulatory effect on the production of IL-6 and the elevation was significantly reduced by SB203580, a specific p38 MAPK inhibitor. SB203580 inhibited...

Major pelvic ganglia (MPG) neurons are classified into sympathetic and parasympathetic neurons according to the electrophysiological properties; membrane capacitance (Cm), expression of T-type Ca2⁢ channels, and the firing patterns during depolarization. In the present study, function and molecular expression of ATP-sensitive K⁢ (KATP) channels was investigated in MPG neurons of male rats. Only in parasympathetic MPG neurons showing phasic firing patterns, hyperpolarizing changes...

In the present study, the postnatal developmental changes in the expressional levels of cardiac sarcoplasmic reticulum (SR) Ca2⁢ regulatory proteins, i.e. Ca2⁢-ATPase, phospholamban, and Ca2⁢ release channel, were investigated. Both SR Ca2⁢-ATPase and phospholamban mRNA levels were about 35% of adult levels at birth and gradually increased to adult levels. Protein levels of both SR Ca2⁢-ATPase and phospholamban, which were measured by quantitative immunoblotting,...

Previous studies have suggested that brain stem noradrenergic inputs differentially modulate neurons in the paraventricular nucleus (PVN). Here, we compared the effects of norepinephrine (NE) on spontaneous GABAergic inhibitory postsynaptic currents (sIPSCs) in identified PVN neurons using slice patch technique. In 17 of 18 type I neurons, NE (30∼100μM) reversibly decreased sIPSC frequency to 41⁑7% of the baseline value (4.4⁑0.8 Hz, p＜0.001). This effect was blocked by yohimbine...

The action of opioid on the hyperpolarization-activated cation current (Ih) in substantia gelatinosa neurons were investigated by using whole-cell voltage-clamp recording in rat spinal brain slices. Hyperpolarizing voltage steps revealed slowly activating currents in a subgroup of neurons. The half-maximal activation and the reversal potential of the current were compatible to neuronal Ih. DAMGO (1μM), a selective- opioid agonist, reduced the amplitude of Ih reversibly. This reduction was...

To define the postnatal changes in ANP secretion 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 aim of the present study is to investigate the contribution of Ca2⁢-activated K⁢ (KCa) channels and delayed rectifier K⁢ (KV) channels to the resting membrane potential (RMP) in rabbit middle cerebral arterial smooth muscle cells. The RMP and membrane currents were recorded using the whole-cell patch configuration and single KCa channel was recorded using the outside-out patch configuration. Using the pipette solution containing 0.05 mM EGTA, the RMP was...

We investigated the role of Ca2⁢ and protein kinases/phosphatases in the stimulatory effect of insulin on glucose transport. In isolated rat adipocytes, the simple omission of CaCl2 from the incubation medium significantly reduced, but did not abolish, insulin-stimulated 2-deoxy glucose (2-DG) uptake. Pre-loading adipocytes with intracellular Ca2⁢ chelator, 5,5'-dimethyl bis (o-aminophenoxy)ethane-N,N,N'N' tetraacetic acetoxymethyl ester (5,5'-dimethyl BAPTA/AM) completely blocked...

An important property of the intestine is the ability to secrete fluid. The intestinal secretion is regulated by a number of substances including vasoactive intestinal peptide (VIP), ATP and different inflammatory mediators. One of the most important secretagogues is adenosine during inflammation. However, the controversy concerning the underlying mechanism of adenosine-stimulated Cl⁣ secretion in intestinal epithelial cells still continues. To investigate the effect of adenosine on...
