To elucidate the functional role of phospholipase Cbeta4 (PLCbeta4), which is highly expressed in the Purkinje cells of the rostral cerebellum, cerebellar long-term depression (LTD) and delay and trace eyeblink conditioning were investigated in PLCbeta4-deficient mice. Rostral cerebellar LTD and delay eyeblink conditioning were severely impaired, whereas(More)
PURPOSE The endothelins (ETs) cause reactive astrogliosis, which involves neuroinflammation and neurodegeneration in the central nervous system. The purpose of this study was to determine whether blocking the ET signals will protect retinal ganglion cells (RGCs) from optic nerve injury. METHODS We studied the effect of pretreatment with BQ-123, an(More)
To elucidate the role of phospholipase Cbeta (PLCbeta) isozymes in the cerebellum, the distributions of PLCbeta3 and PLCbeta4 were examined in wild-type and PLCbeta4-deficient mutant mice using immunohistochemistry, and the functions were evaluated by measurement of type 1 metabotropic glutamate receptor (mGluR1)-mediated inward current and Ca(2+)(More)
Modulation of enzyme activity through nitrosylation has recently been identified as a new physiological activity of nitric oxide (NO). We hypothesized that NO enhances the TNF-α-induced death of retinal neurons through a suppression of nuclear factor-κB (NF-κB) by nitrosylation. In this study, cells from the RGC-5 line were exposed to different(More)
Activation of the type-1 metabotropic glutamate receptor (mGluR1) signaling pathway in the cerebellum involves activation of phospholipase C (PLC) and protein kinase C (PKC) for the induction of cerebellar long term depression (LTD). The PLC and PKC isoforms that are involved in LTD remain unclear, however. One previous study found no change in LTD in(More)
To investigate the clonal origin of multifocal urothelial tumours, we analysed the p53 tumour-suppressor gene in 3 cases with bladder tumours developing after treatment for a renal pelvic or ureteral tumour and in 1 case with a ureteral tumour after treatment for a bladder tumour. For each case, identical p53 gene mutations were detected in all primary and(More)
Laser speckle flowgraphy (LSFG) allows for quantitative estimation of blood flow in the optic nerve head (ONH), choroid and retina, utilizing the laser speckle phenomenon. The basic technology and clinical applications of LSFG-NAVI, the updated model of LSFG, are summarized in this review. For developing a commercial version of LSFG, the special area sensor(More)
To evaluate the response rate and toxicity of the combination of irinotecan (CPT-11) and cisplatin in a neoadjuvant setting, a phase II study was conducted regarding the regimen of this combination in patients with locally advanced cervical cancer. Eligibility included patients with previously untreated stage Ib2, IIb, or IIIb squamous cell carcinoma with(More)
Spontaneously diabetic Torii (SDT) rats are an inbred strain of rats with a non-obese type 2 diabetes mellitus that were isolated from an outbred colony of Sprague-Dawley (SD) rats. Electroretinograms (ERGs) were recorded from SDT and SD (controls) rats at 10- and 44-weeks-of-age to determine their retinal function. The amplitudes and implicit times of the(More)
