water permeability of AQP4 channel expressed in Xenopus oocytes was inhibited by the pretreatment of BAPTA/AM and calmidazolium, a Ca2+/ Calmodulin kinase inhibitor, in a dose-dependent manner. These results indicate that the expression and the function of AQP4 channel are regulated by developmental processes and various pathophysiological conditions. These results will contribute to the understanding of fluid balance in the central nervous system and the osmoregulatory mechanisms of the body.

central nervous system(CNS), the mechanism of taurine in controlling the neuronal excitation in the CNS has been in controversy. Electrically evoked pEPSP and spontaneous activity induced by the perfusion of low Mg⁢⁢-ACSF were recorded in the CA1 pyramidal cell layer of the hippocampal slice. To test the inhibitory effect of taurine on spontaneous responses, taurine was treated for 2 min at various concentrations(1 mM-10 mM). Taurine reduced the spontaneous activity by 22.2% at 1 mM,...

a major role in the development of hypertension. Among these factors angiotensin II (ANG II) is closely involved in renal hypertension development since it directly regulates Na+ reabsorption in the renal proximal tubule. Thus the aim of the present study was to examine signaling pathways of low dose of ANG II on the Na+ uptake of primary cultured rabbit renal proximal tubule cells (PTCs) in hormonally defined serum-free medium. The results were as follows: 1) 10-11 M ANG II has a significant...

no distributional and quantitative differences between the WKY and SHR. In the heart, but the immunoreactivities to PLC-β1 and -γ2 in the SHR were higher than those in WKY. In immunocytochemistry to confirm these western blotting data, PLC-β1 and -γ2 were localized in cardiac myocytes and the intensities of immunoreactivity in SHR were stronger than that in WKY. These results suggest that PLC-β1 and -γ2 would have possibility to concern with the establishment of spontaneous hypertension.

on glutamate uptake was studied in synaptosomes prepared from cerebral cortex. t-BHP inhibited the Na+-dependent glutamate uptake with no change in the Na+-independent uptake. This effect of t-BHP was not altered by addition of Ca2+ channel blockers (verapamil, diltiazem and nifedipine) or PLA2 inhibitors (dibucaine, butacaine and quinacrine). However, the effect was prevented by iron chelators (deferoxamine and phenanthroline) and phenolic antioxidants (N,N'-diphenyl-phenylenediamine, butylated...

in vivo and in slice experiments, the mechanism of the spontaneous activity generation has not been clearly understood. The aim of this study was to investigate whether cerebellar Purkinje cells of postnatal rats generate spontaneous electrical activity without synaptic inputs. Dissociated cerebellar Purkinje cells were used for reducing synaptic inputs in the present study. Cerebellar Purkinje cells with dendrites were dissociated from postnatal rats using enzymatic treatment followed by...

when challenged with TNFα, neither the nature of TNFα-induced cytotoxicity nor the protective mechanism of small HSP has not been completely understood. In this study, we have attempted to determine whether TNFα induces oxidative DNA damage in TNFα-sensitive L929 cells. We chose to measure the level of 8-hydroxy-2′-deoxyguanosine (8 ohdG), which has been increasingly recognized as one of the most sensitive markers of oxidative DNA damage. Our results clearly demonstrated that the level of 8...

of Na+-dependent cycloleucine uptake was investigated in OK cells with regard to substrate specificity and regulation by protein kinase C (PKC). Inhibition studies with different synthetic and natural amino acids showed a broad spectrum affinity to neutral amino acids regardless of their different side chains including branched or aromatic, indicating that the Na+-dependent cycloleucine uptake in OK cells is mediated by System Bo or System Bo-like transporter rather than the classical System A...

which were measured as [3H]-thymidine uptake by the cells and nitrite accumulation in the culture media, respectively. Dexamethasone suppressed ConA-induced cell proliferation, in a concentration-dependent manner with EC50 around 50nM. The addition of anti-lipocortin 1(Anti-LC1) reversed dexamethasone effects: 0.24, 1.2, 6 ㄍg/ml of Anti-LC1 reversed dexamethasone(50 nM)-induced suppression of thymidine uptake by 9⁑3%, 16⁑3%, 36⁑5%, respectively; 0.24, 1.2, and 6...

12 weeks of antidepressant treatment. The baseline serum BDNF and GDNF levels did not significantly between the remission and nonremission groups. The significant alteration in both BDNF and GDNF levels after antidepressant treatment were observed in patients with remission. Conclusion_The present study suggests that the baseline serum BDNF and GDNF levels are higher than the posttreatment levels in some mild-to-moderate MDD outpatients and the significant alteration in BDNF and GDNF level after...
