My research life: from synaptic transmission to behavior.
Abstract   I have studied signal transmission at synapses and the effects of drugs on it at the molecular and cellular levels. Specific areas of research interest are outlined here. 1) Electrophysiological experiments in cats and rabbits suggested that a new type of analgesic, the phenothiazine derivative levomepromazine, exerts analgesic effects by depressing emotional responses accompanying the sensation of pain. 2) It was hypothesized that motoneurons had long-term effects on muscle cell membrane properties, in addition to controlling moment-to-moment activities. The substance to recover the post-denervation c...

Quality evaluation for pharmaceutical products and medical supplies: proper use.
Abstract   In the proper use of medicine, the quality of medical supplies is an important factor. Use of generic products not only reduces drug costs for the patient, but also offers substantial advantages for governments in reducing medical expenses. When evaluation of the quality of generic products is centered on tablets, products with qualities that are unstable over time may be encountered. Some dosage forms require suitable pharmaceutical tests, processes, and apparatuses, such as those for evaluating orally disintegrating tablets or cutaneous preparations. For example, although simple test equipment has be...

Universality of Amino Acid Signaling between Diverse Plasma Cells.
Abstract   Both glutamic (Glu) and gamma-aminobutyric (GABA) acids are believed to play roles as neurotransmitters released from particular neurons into synaptic clefts in the mammalian central nervous system. Although GABA has been shown to act as an extracellular signal outside the brain, little attention has been paid to the possible expression of machineries required for neuronal glutamatergic signaling in cells other than central neurons. We first demonstrated the presence of Glu receptors in peripheral tissues such as the adrenal and pituitary glands three decades ago. In this review, I will outline our exp...

Function of glycochains in virus infection.
Abstract   Influenza A virus (IAV) has two envelope glycoproteins, hemagglutinin (HA) and neuraminidase (NA). HA binds to sialic acids at the terminals of glycochains on the host cell surface as virus receptors. NA shows sialidase activity, which cleaves sialic acids from the terminals of glycochains. A new subtype (antigenicities of HA and NA) of IAV for humans has pandemic potential. We investigated the functions of HA and NA in IAV replication and pandemic potential in terms of glycoscience. We found that the sialidase activity of pandemic IAV had low pH stability, which enhanced IAV replication. It is thought...

The Development of C-C Cross-Coupling Reaction of Monocarba-closo-dodecaborate Anion for the Synthesis of Functional Molecules.
Abstract   A cross-coupling reaction at the carbon vertex of a monocarba-closo-dodecaborate has been developed to allow introduction of various aryl groups and other sp(2)/sp-hybridized carbon centers. A copper(I) complex facilitated the coupling process with a wide range of electrophiles at room temperature. The reaction was successfully used to prepare a series of C-arylated caborane anion derivatives, some of which showed potent androgen-receptor binding activity and excellent mesogenic properties.

Design, Synthesis, and Structure-activity Relationship Study of Organoantimony Compounds That Induce the Expression of Perlecan in Vascular Endothelial Cells.
Abstract   Organometallic compounds and complexes possibly show novel bioactivities unprecedented with organic molecules that consist of C, H, O, and N atoms. We have already reported that an organoantimony compound selectively induces the expression of perlecan, a large heparin sulfate proteoglycan, in cultured vascular endothelial cells. Perlecan consists of a core protein with Mr of approximately 400 kDa and three anticoagulant heparan sulfate glycosaminoglycan chains. However, little is known about the molecular mechanisms of perlecan expression in endothelial cells. Since an organoantimony compound induces t...

Neural Differentiation of Pluripotent Stem Cells and Application for Metal-induced Neural Toxicity Study.
In this study, we investigated an impact of Mn together with Fe and dopamine (DA) on neural differentiation of mouse embryonic stem cells (mESCs). The differentiation of mESCs was initiated by embryoid bodies (EBs) formation in the presence of all-trans retinoic acid, and then EBs were treated with Mn, Fe and/or DA. Then, the mRNA levels of neural differentiation marker genes (Nestin, Emx2, Mtap2, Th, Olig2 and Gfap) were examined using realtime RT-PCR analysis. Mn or DA alone reduced Mtap2, Th and Olig2 expression levels and increased Nestin. Moreover, combined treatment of Mn and DA also increased Nestin expression level...

Development of New Peptide-based Chelating Agents for Site-specific Radiolabeling with (64)Cu.
In this study, we synthesized new peptide derivatives possessing an N-terminal tripeptide sequence (Xaa-Yaa-His) called the amino terminal Cu(2+)- and Ni(2+)-binding (ATCUN) motif as (64)Cu binding peptides for the proposed labeling method. Moreover, we studied the stability constants of Cu(2+)-ATCUN peptide complexes by pH titration. From these studies, we found that a low basicity of the N-terminal amine in the peptide resulted in a high stability constant of the complex. This finding may provide valuable guidelines in designing the ATCUN peptide with high-binding affinity toward (64)Cu. PMID: 24989468 [PubMed - in ...

The Regulation of the Activation in BCR Signaling by ZIP9 Transporter.
Abstract   Zinc is the essential trace element and important for all living organisms. Zinc functions not only as a nutritional factor, but also as a second messenger. However, the effects of intracellular zinc on the B cell-receptor (BCR) signaling pathway are not poorly understood. Here, we indicate that the ZIP9 induces increase in intracellular zinc level and plays an important role in the phosphorylation of Akt and Erk in response to BCR activation. In DT40 cells, the enhancement of Akt and Erk phosphorylation requires intracellular zinc. To clarify this event, we used chicken Zip9-knockout DT40 (cZip9KO) ce...

Activation of cellular defense mechanism by organic-inorganic hybrid molecules.
Abstract   Organic-inorganic hybrid molecules can exhibit biological activities by controlling the activities of their individual components. These molecules can be applied as seed/lead compounds in drug development, and can be used as molecular probes in chemical biology for the elucidation of the molecular mechanisms of biological systems. In this review, we introduce copper diethyldithiocarbamate (Cu10), a copper complex, as a compound that activates nuclear factor erythroid 2-related factor 2 (Nrf2) and induces metallothionein, which are the key cellular defense factors against toxic metals and oxidative stre...

Regulation of Endothelial Cell-specific Robo4 Gene Expression by DNA Methylation and Non-lineage Specific Transcription Factors.
Abstract   Studies of tissue-specific gene expression have suggested that tissue-specific transcription factors or tissue-specific combinations of non-cell-type-specific transcription factors regulate tissue-specific gene expression. Although the studies of endothelial cell (EC)-specific gene expression has identified several transcriptional activators such as SP1, ETS family proteins, and GATA proteins, their expression and combinations are not likely to be EC-specific. To investigate the mechanism of EC-specific gene expression, we analyzed the regulation mechanism of an EC-specific gene, Roundabout4 (Robo4). W...

Effect of Repeated Oral Treatment with Etoposide on the Expression of Intestinal P-glycoprotein and Oral Morphine Analgesia.
Abstract   Currently, the World Health Organization recommends oral administration of opioid analgesics for patients with cancer to treat cancer-related pain from the initial stage of treatment. Furthermore, many anticancer drugs have been newly-developed and approved as oral form. Because of this trend, the chances of drug-drug interactions between anticancer drugs and opioid analgesics during absorption process from the intestine are likely to increase. To investigate these possible drug-drug interactions, we have focused on intestinal P-glycoprotein (P-gp) which regulates the absorption of various substrate dr...

Molecular Organization of Tricellular Tight Junctions.
Abstract   Within an epithelial cellular sheet, the paracellular pathway can be divided into two routes: one between two adjacent cells and one at tricellular contacts, where the vertices of three cells meet. For epithelial barrier function, tight junctions restrict solute permeability through the paracellular pathway between two cells, while tricellular contacts contain specialized structures of tight junctions, named tricellular tight junctions (tTJs). Two types of membrane proteins, tricellulin and angulin family proteins (angulin-1/LSR, angulin-2/ILDR1 and angulin-3/ILDR2) have been identified as molecular co...

Structural and Immunological Barriers of the Skin as Potential Therapeutic Targets.
Abstract   Skin is the structure that covers our body and protects it from not only the entry of pathogens or allergens but also from the leakage of water, solutes or nutrients. These outside-in and inside-out skin barrier functions are dependent on the epidermis, a stratified epithelial cellular sheet. While mucus covers the epidermis in fish and amphibian tadpoles, terminally differentiated cornified cellular sheets called stratum corneum (SC) constitute the outermost epidermal barrier in amphibian adults, reptiles, birds and mammals. Beneath the mucus or SC, apical paracellular spaces of epidermal cells are se...

Claudin 1 as a Target for Anti-hepatitis C Virus Strategy.
Abstract   Chronic hepatitis C virus (HCV) infection is a global public health issue because ~30% of HCV-carriers develop severe liver diseases including hepatic steatosis, cirrhosis, and hepatocellular carcinoma. Not only viral factors but also host/viral interactions are promising targets for antiviral preventive and therapeutic strategies. Recent studies showed that a tight junction protein claudin 1 is involved in HCV entry into host cells. Consistent with these studies, we isolated the several hepatic Huh7-derived cell clones defective in claudin 1 as HCV-resistant mutants, and cellular permissiveness to H...

The New Era of Epithelium-targeted Drug Development.
Abstract   Epithelium plays pivotal roles in biological barrier separating the inside of body and the outside environment. Ninety percent of malignant tumors are derived from epithelium. Most pathological microorganisms invade into the body from mucosal epithelium. Thus, epithelium is potential targets for drug development. Claudins (CLs), a family of tetra-transmembrane protein consisting of over 20 members, are structural and functional components of tight junction-seals in epithelium. Modulation of CL-seals enhanced mucosal absorption of drugs. CLs are often over-expressed in malignant tumors. CL-4 expression ...

Unraveling Molecular Mechanism of Cell Migration Using Novel Perturbation Tools.
Abstract   Complexity in signaling networks is often derived from co-opting particular sets of molecules for multiple operations. Understanding how cells achieve such sophisticated processing using a finite set of molecules within a confined space - what we call the "signaling paradox"- is critical to cell biology and bioengineering as well as the emerging field of synthetic biology. We have recently developed a series of chemical-molecular tools that allow for inducible, quick-onset and specific perturbation of various signaling molecules. The present technique has been employed to unravel several important, pre...

Multivariate Quantification of Acupuncture and Moxibustion Treatment in Combination with Questionnaire and Salivary Stress Markers.
Abstract   Pain and stress alleviation after acupuncture treatment was assessed in this study. Patients responded to a questionnaire designed to determine the amount of stress they were experiencing, and data were obtained for patient salivary amylase, cortisol, secretary IgA (s-IgA), and leptin receptor (OBRb). As a part of this study on acute pain, 6 factors were extracted from the questionnaire. The second factor (pain removal) was well correlated with salivary amylase activity in patients with cervico-omo-brachial syndrome. An evaluation of cumulative acupuncture treatments showed that salivary cortisol incre...

Usefulness of One Point Measurement Method of Pediatric Dose and UV Spectrophotometry for Filterability Test of In-line Filter.
Abstract   The adsorption of Bevacizumab, Trastuzumab, Rituximab, Nedaplatin, Vincristine sulfate, Nogitecan hydrochloride, Actinomycin D and Ramosetron hydrochloride to 0.2 μm endotoxin-retentive in-line filters was evaluated with pediatric doses by UV spectrophotometry. The results indicated that some drug adsorption was shown with Nogitecan hydrochloride, Actinomycin D and Ramosetron hydrochloride, and good recovery was shown with the other five drugs. For the three drugs which showed some losses, drug recovery was investigated at multiple test doses. The approximation formula for each drug adsorption was rec...

Fundamental Study on Effect of High-mineral Drinking Water for Osteogenesis in Calciprivia Ovariectomized Rats.
Abstract   Since osteoporosis is a major public health problem in Japan, it is important to clarify the effect of high-mineral drinking water consumption on osteogenesis. Therefore, in this study, we investigated the relationship between high-mineral drinking water consumption and osteogenesis in ovariectomized rats that received a low-calcium diet and purified water (PW group) or a low-calcium diet and high-mineral drinking water (CR group). High-mineral drinking water affected the rats' body weight. After 3 months, the bone density of the CR group was higher than that of the PW group (p<0.05). Furthermore, t...

A study of the pharmacist work changes associated with dispensing unit-of-use packaging in community pharmacies.
This study aimed to determine how much time can be saved with the use of unit-of-use packaging for prescription drugs as compared with bulk packaging in community pharmacies as well as to determine the number of errors. In a simulation, mock prescriptions were dispensed either in unit-of-use packages or by transferring medication from a bulk container, and a time study was conducted to measure the time spent on dispensing and prescription auditing by pharmacists. Pharmacists' and patients' degree of satisfaction was also surveyed. The time saved with unit-of-use packaging was 66.25 seconds per prescription. The sole dispen...
