We investigated changes in the extracellular levels of acetylcholine (ACh) following local application of serotonergic agents to the dorsal hippocampus of freely moving rats by means of perfusion using a microdialysis technique. Perfusion of serotonin (5-HT; 10 microM, for 30 min at a rate of 3 microliters/min), dissolved in Ringer's solution containing 10(More)
We have isolated a novel mouse gene, MFH-1 (mesenchyme fork head 1) that is related to the Drosophila fork head and rat HNF3 genes. MFH-1 encodes a distinct fork head domain that is classified into a distinct subfamily. A recombinant MFH-1 protein could bind to the HNF3 binding site. MFH-1 is expressed temporally in developing embryos, first in the(More)
Xeroderma pigmentosum (XP) is an autosomal recessive disease, characterized by a high incidence of sunlight-induced skin cancer. Cells from people with this condition are hypersensitive to ultraviolet because of a defect in DNA repair. There are nine genetic complementation groups of XP, groups A-H and a variant. We have cloned the mouse DNA repair gene(More)
Using a newly developed assay of telomerase reverse transcriptase (hTERT) mRNA in serum by real-time RT-PCR, we previously reported this assay to be superior to other tumor markers for hepatoma. In this study, we aimed to clarify its clinical significance as a biomarker for lung cancer. In 112 patients with lung tumor and 80 individuals without cancer, we(More)
We reported a rare case of cerebral infarction with somatoparaphrenia (SP) caused by involvement of the dominant cerebral hemisphere. The patient was 77-year-old right-handed woman who was noted to have atrial fibrillation, right hemiplegia, hemisensory disturbance and ipsilateral homonymous hemianopsia. Neuropsychologically, there were anosognosia (AG) for(More)
To elucidate the mechanisms responsible for sex and age differences in renal methylmercury uptake, effects of castration and testosterone treatment on mercury content and activity of renal gamma-glutamyltranspeptidase (gamma-GTP), which supposedly plays an important role in renal mercury uptake, were investigated in mice. Between 2 and 8 weeks of age, renal(More)
We described recently the molecular cloning of human UDP-galactose transporter 1 (hUGT1) [Miura, N. et al. (1996) J. Biochem. 120, 236-241]. Now we have characterized its isoform, hUGT2, that is most likely generated through the alternative splicing of a transcript derived from the UGT genomic gene, that also codes for hUGT1. Introduction of the open(More)
BACKGROUND & AIMS Wilson's disease is a genetic disorder characterized by the accumulation of copper in the body caused by a defect of biliary copper excretion. The Wilson's disease gene has been cloned; however, the precise localization of the gene product (ATP7B) and its role in biliary copper excretion have not been clarified. METHODS We constructed a(More)
PURPOSE We previously reported the usefulness of a qualified highly sensitive detection method for human telomerase reverse transcriptase (hTERT) mRNA in serum with 89.7% sensitivity for hepatocellular carcinoma (HCC). In this study, we developed a quantitative detection method for serum hTERT mRNA and examined the clinical significance in HCC diagnosis.(More)
Using a genomic library constructed from Saccharomyces cerevisiae, we have identified a gene GFA1 that confers resistance to methylmercury toxicity. GFA1 encodes L-glutamine:D-fructose-6-phosphate amidotransferase (GFAT) and catalyzes synthesis of glucosamine-6-phosphate. Transformed yeast cells expressing GFA1 demonstrated resistance to methylmercury but(More)
