may be isozyme-specific since only PKCՅ antibody inhibited the contraction. MEK inhibitor PD98059 and JNK inhibitor SP600125 blocked the contraction. However, there is no synergistic effect of PKC and MAPK on the LPA-induced contraction. In addition, RhoA inhibitor C3 exoenzyme and ROCK inhibitor Y27632 significantly, but not completely, reduced the contraction. The present study demonstrated that LPA-induced contraction seems to be mediated by LPA receptors (1/3), coupled to PTX-sensitive...

Cardiac fibroblasts constitute one of the largest cell populations in the heart, and contribute to structural, biochemical, mechanical and electrical properties of the myocardium. Nonetheless, their cardiac functions, especially electrophysiological properties, have often been disregarded in studies. Ca2+-activated K+ (KCa) channels can control Ca2+ influx as well as a number of Ca2+-dependent physiological processes. We, therefore, attempted to identify and characterize KCa channels in rat...

200 mg had little effect in MAM- exposed rats. However, ETX 200 mg prolonged the latency to the SE in control groups. Spontaneous field potential and secondary after-discharges were higher for MAM-treated rat in comparison with control rats injects with ETX. The main findings of this study are that acute seizures initiated in MAM-exposed rats are relatively resistant to standard ETX assessed in vivo. These data suggest that ETX do not prolong seizure latencies in MAM-rats exposed to pilocarpine.

the contraction in LES. PLC-β1, -β3 or -γ1 antibody did not reduce the contraction of LES cells in response to DAG (10⁣6 M), suggesting that this isozyme of PLC may not activate PKC. When Gq/11 antibody was incubated, the inhibitory effect of the incubation of PLC β3, but not of PLC β1 was additive (Fig. 6). In contrast, when Gβ antibody was incubated, the inhibitory effect of the incubation of PLC β1, but not of PLC β3 was additive. This data suggest that Gq/11 or Gβ may activate...

Congenital Long QT syndrome (LQTs) is a relatively rare pathologic disorder but results frequently in sudden cardiac death. Of the six LQTs that have been clinically described, five have been worked out for their genetic and biophysical profile. Most are generated by mutations which cause a loss of function in two delayed K⁢currents, iKs and iKr. One syndrome is generated by mutations in the Na⁢ channel which causes essentially a gain of function in the channel. Clinically the...

Contraction of smooth muscle is initiated by an increase in cytosolic Ca2⁢ leading to activation of Ca2⁢/ calmodulin-dependnet myosin light chain (MLC) kinase and phosphorylation of MLC. The types of contraction and signaling mechanisms mediating contraction differ depending on the region. The involvement of these different mechanisms varies depending on the source of Ca2⁢ and the kinetic of Ca2⁢ mobilization. Ca2⁢ mobilizing agonists stimulate different...

It has been proposed that Ca2⁢-activated K⁢ (KCa) channels play an essential role in vascular tone. The alterations of the properties of coronary KCa channels have not been studied as a possible mechanism for impaired coronary reserve in cardiac hypertrophy. The present studies were carried out to determine the properties of coronary KCa channels in normal and hypertrophied hearts. These channels were measured from rabbit coronary smooth muscle cells using a patch clamp technique....

The aim of present study was to define the cellular mechanisms underlying changes in delayed rectifier K⁢ (KDR) channel function in isoproterenol-induced hypertrophy. It has been proposed that KDR channels play a role in regulation of vascular tone by limiting membrane depolarization in arterial smooth muscle cells. The alterations of the properties of coronary KDR channels have not been studied as a possible mechanism for impaired coronary reserve in cardiac hypertrophy. The present...

BBMV to Cd decreased the Na⁢-Pi cotransport activity in proportion to the Cd concentration in the preincubation medium, but it showed no apparent effect on the Pi-protectable PFA binding. These results indicate that an interaction of renal BBM with free Cd induces a reduction in Na⁢-Pi cotransport activity without altering the carrier density in the membrane. This, in turn, suggest that the suppression of phosphate transport capacity (Vmax) observed in Cd-treated renal BBM is due to...

A regulating mechanism of the ATP-sensitive potassium channels (KATP channels) is yet to fully explained. This study was carried out to investigate the effects of intracellular application of monocarboxylates (acetate, formate, lactate, and pyruvate) on KATP channels in isolated rabbit ventricular myocytes. Single channel currents of KATP channels were recorded using the excised inside-out or permeabilized attached (open-cell) patch-clamp technique at room temperature. Intracellular application...
