Although reduced calcium binding protein (CBP) immunoreactivities in the epileptic hippocampus have been well established, it has been controversial that these changes may directly indicate neuronal degeneration. In the present study, therefore, we investigated CBP expressions in the gerbil hippocampus following treatment with gamma-aminobutyric acid (GABA)(More)
Recent studies have demonstrated that blockade of neuronal death in the hippocampus cannot prevent epileptogenesis in various epileptic models. These reports indicate that neurodegeneration alone is insufficient to cause epilepsy, and that the role of astrocytes in epileptogenesis should be reconsidered. Therefore, the present study was designed to(More)
Recently we reported that astroglial loss and subsequent gliogenesis in the dentate gyrus play a role in epileptogenesis following pilocarpine-induced status epilepticus (SE). In the present study we investigated whether astroglial damages in the hippocampo-entorhinal complex following SE are relevant to pathological or electrophysiological properties of(More)
Gastrodin is one of the natural compound isolated from Gastrodia elata and has known anticonvulsant effects, although the exact pharmacological principles of this natural compound and its effects on other aspects of gamma-aminobutyric acid (GABA) metabolism in vivo have not been explored. Therefore, in the present study, the effects of gastrodin on GABA(More)
FK506 binding protein 12 (FK506BP) belongs to a family of immunophilins, and is involved in multiple biological processes. However, the function of FK506BP in corneal disease remains unclear. In this study, we examined the protective effects on dry eye disease in a Botulinum toxin A (BTX-A) induced mouse model, using a cell-permeable PEP-1-FK506BP protein.(More)
K+ -Cl- cotransporter (KCC) plays an important role in maintaining neuronal activity. However, the effect of seizure activity or pharmacological manipulation of GABAergic transmission on KCC expression remains to be clarified. Therefore, the present study was performed to investigate whether seizure activity or GABA receptor agonist treatment changes KCC(More)
The precise mechanism of TGFβ1 signaling in the progression of non-alcoholic steatohepatitis (NASH) has remained unclear. In particular, a potential regulatory mechanism by which PKCδ affects profibrogenic gene expression had never been explored. In this study, therefore, the role of PKCδ in TGFβ1 mediated α-SMA expression was investigated using NASH model(More)
Actin-depolymerizing factor (ADF)/cofilin is a small cytoskeletal protein that is a stimulus-responsive mediator of actin dynamics. ADF/cofilin also translocates into mitochondria and nuclei in response to apoptotic stimuli for cytochrome c release. These ADF/cofilin translocations are negatively regulated by phosphorylation. Recently, it has been reported(More)
In this study, we investigated whether the expression of pyridoxal kinase (PLK) and pyridoxine-5'-phosphate oxidase (PNPO) are altered following long-term potentiation (LTP) induction, and whether Tat-PLK and Tat-PNPO transductions affect LTP induction and paired-pulse responses in the rat dentate gyrus (DG). PNPO immunoreactivity was markedly increased in(More)
Changes in actin dynamics and pyridoxal-5'-phosphate (PLP) metabolisms are closely related to the pathophysiological profiles of the epileptic hippocampus. Recently, it has been reported that PLP phosphatase/chronophin (PLPP/CIN) directly dephosphorylates actin-depolymerizing factor (ADF)/cofilin as well as PLP. In the present study, therefore, we have(More)
