Potassium channels in human skin fibroblast have been studied as a possible site of Alzheimer disease pathogenesis. Fibroblasts in Alzheimer disease show alterations in signal transduction pathway such as changes in Ca2⁢ homeostasis and/or Ca2⁢-activated kinases, phosphatidylinositol cascade, protein kinase C activity, cAMP levels and absence of specific K⁢ channel. However, little is known so far about electrophysiological and pharmacological characteristics of...

receptors (nAChRs) were studied in sympathetic and parasympathetic major pelvic ganglion (MPG) neurons. MPG neurons isolated from male rat were enzymatically dissociated, and ionic currents were recorded by using the whole cell variant patch clamp technique. Total RNA from MPG neuron was prepared, and RT-PCR analysis was performed with specific primers for subunits of nAChRs. ACh dose-dependently elicited fast inward currents in both sympathetic and parasympathetic MPG neurons (EC50; 41.4μM and...

patch-clamp technique. The thiol oxidizing agent 5,5'-dithio-bis-(2-nitro-benzoic acid) (DTNB) inhibited the channel activity, and the inhibitory effect of DTNB was reversed by dithiothreitol (disulfide reducing agent; DTT). DTT itself did not have any effect on the channel activity. However, in the patches excised from the metabolically compromised cells, DTT increased the channel activity. DTT had no effect on the inhibitory action by ATP, showing that thiol oxidation was not involved in the...

Ischemic damage is one of the most serious problems. The openers of KATP channel have been suggested to have an effect to limit the ischemic damage. However, it is not yet clear how KATP channels of a cell correspond to hypoxic damage. To address the question, N2a cells were exposed to two different hypoxic conditions as follows: 6 hours hypoxia followed by 3 hours reperfusion and 12 hours hypoxia followed by 3 hours reperfusion. As the results, 6 hours hypoxic treatment increased...

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 (2∼20μM), an α2-adrenoceptor antagonist and mimicked by clonidine (50μM), an α2-adrenoceptor agonist. In contrast, NE increased sIPSC frequency to 248⁑32% of the control (3.06⁑0.37 Hz, p＜0.001) in 31 of 54 type II neurons, but decreased the...

using a patch clamp technique. The main findings of the study are as follows: (1) the KDR current density was decreased without changes of the channel kinetics in isoproterenol-induced hypertrophy; (2) the sensitivity of coronary KDR channels to 4-AP was increased in isoproterenol-induced hypertrophy. From the above results, we suggest for the first time that the alteration of KDR channels may limit vasodilating responses to several stimuli and may be involved in impaired coronary reserve in...

Chronic exposure to cadmium (Cd) results in an inhibition of protein endocytosis in the renal proximal tubule, leading to proteinuria. In order to gain insight into the mechanism by which Cd impairs the protein endocytosis, we investigated the effect of Cd on the acidification of renal cortical endocytotic vesicles (endosomes). The endosomal acidification was assessed by measuring the pH gradient-dependent fluorescence change, using acridine orange or FITC-dextran as a probe. In renal endosomes...

Decreased cardiac contractility occurs in endotoxicosis, but little is known about the ionic mechanism responsible for myocardial dysfunction. In this study, we examined the changes in Ca2⁢ and K⁢ currents in cardiac myocytes from endotoxin-treated rat. Ventricular myocytes were isolated from normal and endotoxemic rats (ex vivo), that were treated for 10 hours with Salmonella enteritidis lipopolysaccharides (LPS; 1.5 mg/kg) intravenously. Normal cardiac myocytes were also incubated...

To explore whether Cl⁣ channel blockers interact with the ATP-sensitive K⁢ (KATP) channel, I have examined the effect of two common Cl⁣ channel blockers on the KATP channel activity in isolated rat ventricular myocytes using patch clamp techniques. In inside-out patches, 4,4'-diisothio-cyanatostilbene- 2,2'-disulfonic acid (DIDS) and niflumic acid applied to bath solution inhibited the KATP channel activity in a concentration-dependent manner with IC50 of 0.24 and 927μM,...

Kinetic analysis showed that ethanol caused a decrease in Vmax of three transport systems, leaving Km values unchanged. Ethanol decreased phlorizin binding, which was closely correlated with the decrease in Vmax of Na⁢-glucose uptake. These results indicate that ethanol inhibits Na⁢-dependent uptakes of glucose, phosphate, and dicaboxylate and that the reduction in Vmax of Na⁢-glucose uptake is caused by a decrease in the number of active carrier proteins in the membrane.
