In 2024, the International Committee on Taxonomy of Viruses Animal dsRNA and ssRNA(−) Viruses Subcommittee submitted 18 taxonomic proposals for consideration. These proposals expanded the known virosphere by classifying 9 new genera and 88 species for newly detected virus genomes. Of note, newly established species expand the large family of Rhabdoviridae to 580 species. A new species in the family Arenaviridae includes a virus detected in Antarctic fish with a unique split nucleoprotein ORF. Additionally, four new species were established for historically isolated viruses with previously unsequenced genomes. Furthermore, three species were abolished due to incomplete genome sequence information, and one family was moved from being unassigned in the phylum Negarnaviricota into a subphylum and order. Herein, we summarize the 18 ratified taxonomic proposals and the general features of the current taxonomy, thereby supporting public and animal health responses. en-copyright= kn-copyright=

The unique wavy backbone of these polymers effectively reduced aggregation, leading to enhanced solubility and significantly improved molecular ordering. Consequently, the PATz3T-o6HD:Y12-based solar cells achieved a power conversion efficiency (PCE) of 7.94%.

The urgent need for robust security measures is predicated on a comprehensive understanding of the behavioral patterns of IoT malware. However, previous studies have often overlooked the analysis of command sequences in Telnet logs. This study bridges this research gap by examining the post-injection behaviors of attackers. By analyzing a vast dataset comprising more than ten million logs collected from an IoT honeypot, we reveal three distinct post-injection activity patterns, each with unique characteristics. These patterns provide pivotal insights that not only help distinguish between legitimate operations and attempted attacks, but also drive the development of robust cybersecurity measures that effectively deter such behaviors. The nuances discovered in this study contribute significantly to IoT security by enhancing our understanding of malware tactics and informing targeted defense strategies. en-copyright= kn-copyright= en-aut-name=VictorHervet en-aut-sei=Victor en-aut-mei=Hervet kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KobayashiSatoru en-aut-sei=Kobayashi en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamauchiToshihiro en-aut-sei=Yamauchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Okayama University kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Malware analysis kn-keyword=Malware analysis en-keyword=IoT kn-keyword=IoT en-keyword=Honeypot kn-keyword=Honeypot en-keyword=Log analysis kn-keyword=Log analysis en-keyword=Attack patterns kn-keyword=Attack patterns END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=6 article-no= start-page=1208 end-page=1219 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231210 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Nuclear Transformation of the Marine Pennate Diatom Nitzschia sp. Strain NIES-4635 by Multi-Pulse Electroporation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Nitzschia is one of the largest genera of diatoms found in a range of aquatic environments, from freshwater to seawater. This genus contains evolutionarily and ecologically unique species, such as those that have lost photosynthetic capacity or those that live symbiotically in dinoflagellates. Several Nitzschia species have been used as indicators of water pollution. Recently, Nitzschia species have attracted considerable attention in the field of biotechnology. In this study, a transformation method for the marine pennate diatom Nitzschia sp. strain NIES-4635, isolated from the coastal Seto Inland Sea, was established. Plasmids containing the promoter/terminator of the fucoxanthin chlorophyll a/c binding protein gene (fcp, or Lhcf) derived from Nitzschia palea were constructed and introduced into cells by multi-pulse electroporation, resulting in 500 μg/mL nourseothricin-resistant transformants with transformation frequencies of up to 365 colonies per 108 cells. In addition, when transformation was performed using a new plasmid containing a promoter derived from a diatom-infecting virus upstream of the green fluorescent protein gene (gfp), 44% of the nourseothricin-resistant clones exhibited GFP fluorescence. The integration of the genes introduced into the genomes of the transformants was confirmed by Southern blotting. The Nitzschia transformation method established in this study will enable the transformation this species, thus allowing the functional analysis of genes from the genus Nitzschia, which are important species for environmental and biotechnological development. en-copyright= kn-copyright= en-aut-name=OkadaKoki en-aut-sei=Okada en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MorimotoYu en-aut-sei=Morimoto en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShiraishiYukine en-aut-sei=Shiraishi en-aut-mei=Yukine kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TamuraTakashi en-aut-sei=Tamura en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MayamaShigeki en-aut-sei=Mayama en-aut-mei=Shigeki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KadonoTakashi en-aut-sei=Kadono en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AdachiMasao en-aut-sei=Adachi en-aut-mei=Masao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IfukuKentaro en-aut-sei=Ifuku en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NemotoMichiko en-aut-sei=Nemoto en-aut-mei=Michiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=The Advanced Support Center for Science Teachers, Tokyo Gakugei University kn-affil= affil-num=6 en-affil=Faculty of Agriculture and Marine Science, Kochi University kn-affil= affil-num=7 en-affil=Faculty of Agriculture and Marine Science, Kochi University kn-affil= affil-num=8 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=9 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Diatom kn-keyword=Diatom en-keyword=Genetic transformation kn-keyword=Genetic transformation en-keyword=Nitzschia kn-keyword=Nitzschia en-keyword=Multi-pulse electroporation kn-keyword=Multi-pulse electroporation END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=5 article-no= start-page=503 end-page=510 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202210 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Viral Sequences Are Repurposed for Controlling Antiviral Responses as Non-Retroviral Endogenous Viral Elements en-subtitle= kn-subtitle= en-abstract= kn-abstract=Eukaryotic genomes contain numerous copies of endogenous viral elements (EVEs), most of which are considered endogenous retrovirus (ERV) sequences. Over the past decade, non-retroviral endogenous viral elements (nrEVEs) derived from ancient RNA viruses have been discovered. Several functions have been proposed for these elements, including antiviral defense. This review summarizes the current understanding of nrEVEs derived from RNA viruses, particularly endogenous bornavirus-like elements (EBLs) and endogenous filovirus-like elements (EFLs). EBLs are one of the most extensively studied nrEVEs. The EBL derived from bornavirus nucleoprotein (EBLN) is thought to function as a non-coding RNA or protein that regulates host gene expression or inhibits virus propagation. Ebolavirus and marburgvirus, which are filoviruses, induce severe hemorrhagic fever in humans and nonhuman primates. Although the ecology of filoviruses remains unclear, bats are believed to be potential reservoirs. Based on the knowledge from EBLs, it is postulated that EFLs in the bat genome help to maintain the balance between filovirus infection and the bat’s defense system, which may partially explain why bats act as potential reservoirs. Further research into the functions of nrEVEs could reveal novel antiviral systems and inspire novel antiviral approaches. en-copyright= kn-copyright= en-aut-name=OgawaHirohito en-aut-sei=Ogawa en-aut-mei=Hirohito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HondaTomoyuki en-aut-sei=Honda en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Virology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Virology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=EVE kn-keyword=EVE en-keyword=nrEVE kn-keyword=nrEVE en-keyword=bornavirus kn-keyword=bornavirus en-keyword=filovirus kn-keyword=filovirus en-keyword=antiviral kn-keyword=antiviral END start-ver=1.4 cd-journal=joma no-vol=307 cd-vols= no-issue=2 article-no= start-page=198606 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A new tetra-segmented splipalmivirus with divided RdRP domains from Cryphonectria naterciae, a fungus found on chestnut and cork oak trees in Europe en-subtitle= kn-subtitle= en-abstract= kn-abstract=Positive-sense (+), single-stranded (ss) RNA viruses with divided RNA-dependent RNA polymerase (RdRP) domains have been reported from diverse filamentous ascomycetes since 2020. These viruses are termed splipalmiviruses or polynarnaviruses and have been characterized largely at the sequence level, but ill-defined biologically. Cryphonectria naterciae, from which only one virus has been reported, is an ascomycetous fungus potentially plant-pathogenic to chestnut and oak trees. We molecularly characterized multiple viruses in a single Portuguese isolate (C0614) of C. naterciae, taking a metatranscriptomic and conventional double-stranded RNA approach. Among them are a novel splipalmivirus (Cryphonectria naterciae splipalmivirus 1, CnSpV1) and a novel fusagravirus (Cryphonectria naterciae fusagravirus 1, CnFGV1). This study focused on the former virus. CnSpV1 has a tetra-segmented, (+)ssRNA genome (RNA1 to RNA4). As observed for other splipalmiviruses reported in 2020 and 2021, the RdRP domain is separately encoded by RNA1 (motifs F, A and B) and RNA2 (motifs C and D). A hypothetical protein encoded by the 5′-proximal open reading frame of RNA3 shows similarity to a counterpart conserved in some splipalmiviruses. The other RNA3-encoded protein and RNA4-encoded protein show no similarity with known proteins in a blastp search. The tetra-segment nature was confirmed by the conserved terminal sequences of the four CnSpV1 segments (RNA1 to RNA4) and their 100% coexistence in over 100 single conidial isolates tested. The experimental introduction of CnSpV1 along with CnFGV1 into a virus free strain C0754 of C. naterciae vegetatively incompatible with C0614 resulted in no phenotypic alteration, suggesting asymptomatic infection. The protoplast fusion assay indicates a considerably narrow host range of CnSpV1, restricted to the species C. naterciae and C. carpinicola. This study contributes to better understanding of the molecular and biological properties of this unique group of viruses. en-copyright= kn-copyright= en-aut-name=SatoYukiyo en-aut-sei=Sato en-aut-mei=Yukiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShahiSabitree en-aut-sei=Shahi en-aut-mei=Sabitree kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TelengechPaul en-aut-sei=Telengech en-aut-mei=Paul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HisanoSakae en-aut-sei=Hisano en-aut-mei=Sakae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=CornejoCarolina en-aut-sei=Cornejo en-aut-mei=Carolina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=RiglingDaniel en-aut-sei=Rigling en-aut-mei=Daniel kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KondoHideki en-aut-sei=Kondo en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SuzukiNobuhiro en-aut-sei=Suzuki en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=4 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=5 en-affil=Swiss Federal Research Institute WSL, Forest Health & Biotic Interactions kn-affil= affil-num=6 en-affil=Swiss Federal Research Institute WSL, Forest Health & Biotic Interactions kn-affil= affil-num=7 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=8 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=Splipalmivirus kn-keyword=Splipalmivirus en-keyword=Capsidless kn-keyword=Capsidless en-keyword=RNA virus kn-keyword=RNA virus en-keyword=Cryphonectria naterciae kn-keyword=Cryphonectria naterciae en-keyword=Narnavirus kn-keyword=Narnavirus en-keyword=Fungal virus kn-keyword=Fungal virus en-keyword=Mycovirus kn-keyword=Mycovirus END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue=3 article-no= start-page=60 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200821 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Metastasis Model of Cancer Stem Cell-Derived Tumors en-subtitle= kn-subtitle= en-abstract= kn-abstract=Metastasis includes the dissemination of cancer cells from a malignant tumor and seed in distant sites inside the body forming secondary tumors. Metastatic cells from the primary tumor can move even before the cancer is detected. Therefore, metastases are responsible for more than 90% of cancer-related deaths. Over recent decades there has been adequate evidence suggesting the existence of CSCs with self-renewing and drug-resistant potency within heterogeneous tumors. Cancer stem cells (CSCs) act as a tumor initiating cells and have roles in tumor retrieve and metastasis. Our group recently developed a unique CSC model from mouse induced pluripotent stem cells cultured in the presence of cancer cell-conditioned medium that mimics tumors microenvironment. Using this model, we demonstrated a new method for studying metastasis by intraperitoneal transplantation of tumors and investigate the metastasis ability of cells from these segments. First of all, CSCs were injected subcutaneously in nude mice. The developed malignant tumors were minimized then transplanted into the peritoneal cavity. Following this, the developed tumor in addition to lung, pancreas and liver were then excised and analyzed. Our method showed the metastatic potential of CSCs with the ability of disseminated and moving to blood circulation and seeding in distant organs such as lung and pancreas. This method could provide a good model to study the mechanisms of metastasis according to CSC theory. en-copyright= kn-copyright= en-aut-name=MansourHager en-aut-sei=Mansour en-aut-mei=Hager kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HassanGhmkin en-aut-sei=Hassan en-aut-mei=Ghmkin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AfifySaid M. en-aut-sei=Afify en-aut-mei=Said M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YanTing en-aut-sei=Yan en-aut-mei=Ting kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SenoAkimasa en-aut-sei=Seno en-aut-mei=Akimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SenoMasaharu en-aut-sei=Seno en-aut-mei=Masaharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Medical Bioengineering, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Laboratory of Nano-Biotechnology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Laboratory of Nano-Biotechnology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Department of Pathology, Shanxi Key Laboratory of Carcinogenesis and Translational Research on Esophageal Cancer, Shanxi Medical University kn-affil= affil-num=5 en-affil=Department of Medical Bioengineering, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Department of Medical Bioengineering, Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=metastasis kn-keyword=metastasis en-keyword=cancer stem cells kn-keyword=cancer stem cells en-keyword=transplantation kn-keyword=transplantation en-keyword=surgery kn-keyword=surgery END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=1 article-no= start-page=266 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210710 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Genome sequence analysis of new plum pox virus isolates from Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective To find mutations that may have recently occurred in Plum pox virus (PPV), we collected six PPV-infected plum/peach trees from the western part of Japan and one from the eastern part. After sequencing the full-length PPV genomic RNAs, we compared the amino acid sequences with representative isolates of each PPV strain. Results All new isolates were found to belong to the PPV-D strain: the six isolates collected from western Japan were identified as the West-Japan strain while the one collected from eastern Japan as the East-Japan strain. Amino acid sequence analysis of these seven isolates suggested that the 1407th and 1529th amino acid residues are characteristic of the West-Japan and the East-Japan strains, respectively. Comparing them with the corresponding amino acid residues of the 47 non-Japanese PPV-D isolates revealed that these amino acid residues are undoubtedly unique. A further examination of the relevant amino acid residues of the other 210 PPV-D isolates collected in Japan generated a new hypothesis regarding the invasion route from overseas and the subsequent diffusion route within Japan: a PPV-D strain might have invaded the western part of Japan from overseas and spread throughout Japan. en-copyright= kn-copyright= en-aut-name=MoriTomoaki en-aut-sei=Mori en-aut-mei=Tomoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WarnerChiaki en-aut-sei=Warner en-aut-mei=Chiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OhnoSerika en-aut-sei=Ohno en-aut-mei=Serika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoriKoichi en-aut-sei=Mori en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TobimatsuTakamasa en-aut-sei=Tobimatsu en-aut-mei=Takamasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SeraTakashi en-aut-sei=Sera en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Applied Chemistry and Biotechnology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Applied Chemistry and Biotechnology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Department of Applied Chemistry and Biotechnology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Department of Applied Chemistry and Biotechnology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=5 en-affil=Department of Applied Chemistry and Biotechnology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=6 en-affil=Department of Applied Chemistry and Biotechnology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=Plum pox virus kn-keyword=Plum pox virus en-keyword=Complete genome sequence kn-keyword=Complete genome sequence en-keyword=Phylogenetic analysis kn-keyword=Phylogenetic analysis en-keyword=Sequence alignment analysis kn-keyword=Sequence alignment analysis en-keyword=Genetic variation kn-keyword=Genetic variation END start-ver=1.4 cd-journal=joma no-vol=330 cd-vols= no-issue= article-no= start-page=788 end-page=196 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20201111 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Self-assembling A6K peptide nanotubes as a mercaptoundecahydrododecaborate (BSH) delivery system for boron neutron capture t (BNCT) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Boron neutron capture therapy (BNCT) is a tumor selective therapy, the effectiveness of which depends on sufficient 10B delivery to and accumulation in tumors. In this study, we used self-assembling A6K peptide nanotubes as boron carriers and prepared new boron agents by simple mixing of A6K and BSH. BSH has been used to treat malignant glioma patients in clinical trials and its drug safety and availability have been confirmed; however, its contribution to BNCT efficacy is low. A6K nanotube delivery improved two major limitations of BSH, including absence of intracellular transduction and non-specific drug delivery to tumor tissue. Varying the A6K peptide and BSH mixture ratio produced materials with different morphologies—determined by electron microscopy—and intracellular transduction efficiencies. We investigated the A6K/BSH 1:10 mixture ratio and found high intracellular boron uptake with no toxicity. Microscopy observation showed intracellular localization of A6K/BSH in the perinuclear region and endosome in human glioma cells. The intracellular boron concentration using A6K/BSH was almost 10 times higher than that of BSH. The systematic administration of A6K/BSH via mouse tail vein showed tumor specific accumulation in a mouse brain tumor model with immunohistochemistry and pharmacokinetic study. Neutron irradiation of glioma cells treated with A6K/BSH showed the inhibition of cell proliferation in a colony formation assay. Boron delivery using A6K peptide provides a unique and simple strategy for next generation BNCT drugs. en-copyright= kn-copyright= en-aut-name=MichiueHiroyuki en-aut-sei=Michiue en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KitamatsuMizuki en-aut-sei=Kitamatsu en-aut-mei=Mizuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FukunagaAsami en-aut-sei=Fukunaga en-aut-mei=Asami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsuboiNobushige en-aut-sei=Tsuboi en-aut-mei=Nobushige kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujimuraAtsushi en-aut-sei=Fujimura en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatsushitaHiroaki en-aut-sei=Matsushita en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IgawaKazuyo en-aut-sei=Igawa en-aut-mei=Kazuyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KasaiTomonari en-aut-sei=Kasai en-aut-mei=Tomonari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KondoNatsuko en-aut-sei=Kondo en-aut-mei=Natsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MatsuiHideki en-aut-sei=Matsui en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=FuruyaShuichi en-aut-sei=Furuya en-aut-mei=Shuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Neutron Therapy Research Center, Okayama University kn-affil= affil-num=2 en-affil=Department of Applied Chemistry, Kindai University kn-affil= affil-num=3 en-affil=Department of Physiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Physiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Physiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Neutron Therapy Research Center, Okayama University kn-affil= affil-num=8 en-affil=Neutron Therapy Research Center, Okayama University kn-affil= affil-num=9 en-affil=Institute for Integrated Radiation and Nuclear Science, Kyoto University kn-affil= affil-num=10 en-affil=Neutron Therapy Research Center, Okayama University kn-affil= affil-num=11 en-affil=Neutron Therapy Research Center, Okayama University kn-affil= en-keyword=Malignant brain tumor kn-keyword=Malignant brain tumor en-keyword=Boron neutron capture therapy (BNCT) kn-keyword=Boron neutron capture therapy (BNCT) en-keyword=Peptide nanotube kn-keyword=Peptide nanotube en-keyword=Boron drug kn-keyword=Boron drug en-keyword=Drug delivery system (DDS) kn-keyword=Drug delivery system (DDS) en-keyword=A6K peptide kn-keyword=A6K peptide END start-ver=1.4 cd-journal=joma no-vol=68 cd-vols= no-issue=1 article-no= start-page=197 end-page=200 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20191231 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=High surface quality micro machining of monocrystalline diamond by picosecond pulsed laser en-subtitle= kn-subtitle= en-abstract= kn-abstract=In micro machining of monocrystalline diamond by pulsed laser, unique processing characteristics appeared only under a few ten picosecond pulse duration and a certain overlap rate of laser shot. Cracks mostly propagate in parallel direction to top surface of workpiece, although the laser beam axis is perpendicular to the surface. This processed area can keep diamond structure, and its surface roughness is smaller than R-a = 0.2 mu M. New laser micro machining method to keep diamond structure and small surface roughness is proposed. This method can contribute to reduce the polishing process in micro machining of diamond.

Recent genetic and epigenetic analyses of glioma have revealed increasing evidence of the role of driver genetic alterations in glioma development and led to the identification of prognostic factors. Despite these findings, the survival rates of glioma patients remain low, and alternative treatments and novel targets are needed. Recent studies identified neural stem cells as the possible origin of gliomas, and some evidence has revealed shared functions and mechanisms between glioma cells and neurons, also supporting their similarity. The cytoskeleton plays important roles in the migration of normal cells as well as cancer cells. Recent reports have described a role for microtubules, a component of the cytoskeleton, in glioma invasion. Notably, several factors that regulate microtubule functions, such as microtubule-associated proteins, plus-end tracking proteins, or motor proteins, are upregulated in glioma tissues compared with normal tissue, and upregulation of these factors is associated with high invasiveness of glioma cells. In this review, we describe the mechanism of microtubules in glioma invasion and discuss the possibility of microtubule-targeted therapy to inhibit glioma invasion. en-copyright= kn-copyright= en-aut-name=OtaniYoshihiro en-aut-sei=Otani en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IchikawaTomotsugu en-aut-sei=Ichikawa en-aut-mei=Tomotsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KurozumiKazuhiko en-aut-sei=Kurozumi en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Neurosurgery, The University of Texas Health Science Center at Houston kn-affil= affil-num=2 en-affil=Department of Neurosurgery, Kagawa Prefectural Central Hospital kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=glioma kn-keyword=glioma en-keyword=cytoskeletons kn-keyword=cytoskeletons en-keyword=invasion kn-keyword=invasion en-keyword=microtubules kn-keyword=microtubules END start-ver=1.4 cd-journal=joma no-vol=543 cd-vols= no-issue=7643 article-no= start-page=131 end-page=135 dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=201703 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Light-induced structural changes and the site of O=O bond formation in PSII caught by XFEL en-subtitle= kn-subtitle= en-abstract= kn-abstract= Photosystem II (PSII) is a huge membrane-protein complex consisting of 20 different subunits with a total molecular mass of 350 kDa for a monomer. It catalyses light-driven water oxidation at its catalytic centre, the oxygen-evolving complex (OEC). The structure of PSII has been analysed at 1.9 Å resolution by synchrotron radiation X-rays, which revealed that the OEC is a Mn4CaO5 cluster organized in an asymmetric, 'distorted-chair' form. This structure was further analysed with femtosecond X-ray free electron lasers (XFEL), providing the 'radiation damage-free' structure. The mechanism of O=O bond formation, however, remains obscure owing to the lack of intermediate-state structures. Here we describe the structural changes in PSII induced by two-flash illumination at room temperature at a resolution of 2.35 Å using time-resolved serial femtosecond crystallography with an XFEL provided by the SPring-8 ångström compact free-electron laser. An isomorphous difference Fourier map between the two-flash and dark-adapted states revealed two areas of apparent changes: around the QB/non-haem iron and the Mn4CaO5 cluster. The changes around the QB/non-haem iron region reflected the electron and proton transfers induced by the two-flash illumination. In the region around the OEC, a water molecule located 3.5 Å from the Mn4CaO5 cluster disappeared from the map upon two-flash illumination. This reduced the distance between another water molecule and the oxygen atom O4, suggesting that proton transfer also occurred. Importantly, the two-flash-minus-dark isomorphous difference Fourier map showed an apparent positive peak around O5, a unique μ4-oxo-bridge located in the quasi-centre of Mn1 and Mn4 (refs 4,5). This suggests the insertion of a new oxygen atom (O6) close to O5, providing an O=O distance of 1.5 Å between these two oxygen atoms. This provides a mechanism for the O=O bond formation consistent with that proposed previously en-copyright= kn-copyright= en-aut-name=SugaMichihiro en-aut-sei=Suga en-aut-mei=Michihiro kn-aut-name=

Kimura et al., Biosci. Biotechnol Biochem., 70, 2583-2587, 2006), we found that new complex type N-glycans harboring Thomsen-Friedenreich antigen (Ga1 beta 1-3GalNAc) unit occur on royal jelly glycoproteins, suggesting the involvement of a new beta 1-3galactosyltransferase in the synthesis of the unusual complex type N-glycans. So far, such beta 1-3galactosyltransferase activity, which can transfer galactosyl residues with the beta 1-3 linkage to beta 1-4 GalNAc residues in N-glycan, has not been found among any eucaryotic cells. But using GalNAc(2)GlcNAc(2)Man(3)-GlcNAc(2)-PA as acceptor N-glycan, we detected the beta 1-3 galactosyltransferase activity in membrane fraction prepared from honeybee cephalic portions. This result indicates that honeybee expresses a unique beta 1-3 galactosyltransferase involved in biosynthesis of the unusual N-glycan containing a tumor related antigen in the hypopharyngeal gland. en-copyright= kn-copyright= en-aut-name=KimuraYoshinobu en-aut-sei=Kimura en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakamuraSho en-aut-sei=Sakamura en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UshijimaTakayuki en-aut-sei=Ushijima en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HamaYoichiro en-aut-sei=Hama en-aut-mei=Yoichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KajiuraHiroyuki en-aut-sei=Kajiura en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujiyamaKazuhito en-aut-sei=Fujiyama en-aut-mei=Kazuhito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkiharaKiyoshi en-aut-sei=Okihara en-aut-mei=Kiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HashimotoKen en-aut-sei=Hashimoto en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SugimotoHiroyuki en-aut-sei=Sugimoto en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YamadaHideo en-aut-sei=Yamada en-aut-mei=Hideo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil= kn-affil=Department of Biofunctional Chemistry, Division of Bioscience, Graduate School of Natural Science and Technology, Okayama University affil-num=2 en-affil= kn-affil=Department of Biofunctional Chemistry, Division of Bioscience, Graduate School of Natural Science and Technology, Okayama University affil-num=3 en-affil= kn-affil=Department of Biofunctional Chemistry, Division of Bioscience, Graduate School of Natural Science and Technology, Okayama University affil-num=4 en-affil= kn-affil=Department of Applied Biological Sciences, Faculty of Agriculture, Saga University affil-num=5 en-affil= kn-affil=The International Center for Biotechnology, Osaka University affil-num=6 en-affil= kn-affil=The International Center for Biotechnology, Osaka University affil-num=7 en-affil= kn-affil=Yamada Apiculture Center, Inc. affil-num=8 en-affil= kn-affil=Yamada Apiculture Center, Inc. affil-num=9 en-affil= kn-affil=Yamada Apiculture Center, Inc. affil-num=10 en-affil= kn-affil=Yamada Apiculture Center, Inc. en-keyword=royal jelly glycoprotein; N-glycan kn-keyword=royal jelly glycoprotein; N-glycan en-keyword=Thomsen-Friedenreich antigen (Gal beta 1-3GalNAc) kn-keyword=Thomsen-Friedenreich antigen (Gal beta 1-3GalNAc) en-keyword=beta 1-3 galactosyltransferase kn-keyword=beta 1-3 galactosyltransferase en-keyword=Apis mellifera kn-keyword=Apis mellifera END start-ver=1.4 cd-journal=joma no-vol=105 cd-vols= no-issue=7-8 article-no= start-page=759 end-page=770 dt-received= dt-revised= dt-accepted= dt-pub-year=1993 dt-pub=199308 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the pathogenesis of anti-IgE autoantibody in bronchial asthma kn-title=気管支喘息における血清抗 IgE 自己抗体の基礎的並びに臨床的研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=To clarify the pathogenesis of asthma especially intractable asthma, we measured the serum levels of anti-IgE autoantibody in 46 asthmatics and 39 healthy subjects, using solid-phase enzyme immunoassay. The serum levels of anti-IgE autoantibody in bronchial asthmatics were significantly higher than those in healthy subjects (p<0.01). The levels of anti-IgE autoantibody in 25 atopic asthmatics were also significantly higher than those in 19 non-atopic asthmatics (p<0.01). Futhermore, significant correlation was observed between the levels of anti-IgE autoantibody and serum IgE (r=0.576, p<0.01). House dust and Candida (p<0.01) specific IgE (RAST) positive asthmatics also tended to have higher serum levels of anti-IgE autoantibody. However, no significant relation was observed between the serum levels of anti-IgE autoantibody and the severity of asthma. Moreover, anti-IgE autoantibody was not significantly related to specific IgG subclass antibody or lymphocyte blastogenesis to mite and Candida, or with the numbers of eosinophils and basophils in peripheral blood. These findings suggest that anti-IgE autoantibody play an important role in the pathogenesis of bronchial asthma, especially atopic asthma associated with IgE-dependent mechanisms. en-copyright= kn-copyright= en-aut-name=YamagataKoichi en-aut-sei=Yamagata en-aut-mei=Koichi kn-aut-name=山縣浩一 kn-aut-sei=山縣 kn-aut-mei=浩一 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=抗 IgE 自己抗体 kn-keyword=抗 IgE 自己抗体 en-keyword=アトピー型喘息 kn-keyword=アトピー型喘息 en-keyword=IgE 抗体 kn-keyword=IgE 抗体 en-keyword=IgG アイソタイプ抗体 kn-keyword=IgG アイソタイプ抗体 en-keyword=酵素抗体法 kn-keyword=酵素抗体法 END start-ver=1.4 cd-journal=joma no-vol=106 cd-vols= no-issue=7-8 article-no= start-page=847 end-page=860 dt-received= dt-revised= dt-accepted= dt-pub-year=1994 dt-pub=199408 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The mechanism of human basophil activation through the low affinity IgG receptor (Fc γ RⅡ) : Analysis of calcium mobilization using a new flow cytometric method kn-title=低親和性 IgG レセプター（FcγRⅡ）を介するヒト好塩基球の活性化機序に関する研究―フローサイトメーターによるカルシウム動態の解析― en-subtitle= kn-subtitle= en-abstract= kn-abstract=A new method for flow cytometric analysis of calcium mobilization in human peripheral blood basophils without prior purification was developed. The method is based on dual color analysis of centrifugation-enriched mononuclear cell populations using fluo-3 and phycoerythrin (PE)-conjugated CD2, CD14, CD16, CD19 monoclonal antibodies (mAb) to stain contaminated cells. This technique allows the detection of fluo-3 fluorescence as a measure of an increase in the cytoplasmic free calcium concentration ([Ca(2+)]i) while simulataneously discriminating PE-mAb-unlabelled basophils. To clarify whether the human peripheral blood basophil is activated through the low affinity IgG receptor, Fc γ RⅡ, as well as the high affinity IgE receptor, Fc ε　RⅠ, calcium mobilization after Fc γ RⅡ stimulation was analyzed by this method. After cross-linking of Fc γ RⅡ, transient [Ca(2+)]i elevation was observed but there was no apparent difference with interleukin-3(IL-3)-treated cells, and no significant histamine release was observed with or without short pre-incubation of IL-3. These findings suggest that the cross-linking of Fc γ RⅡ, not only Fc ε　RⅠ, can activate human basophils which may result in mediator release other than histamine. en-copyright= kn-copyright= en-aut-name=SuwakiToshimitsu en-aut-sei=Suwaki en-aut-mei=Toshimitsu kn-aut-name=洲脇俊充 kn-aut-sei=洲脇 kn-aut-mei=俊充 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=basophils kn-keyword=basophils en-keyword=FcγRⅡ kn-keyword=FcγRⅡ en-keyword=fluo-3 kn-keyword=fluo-3 en-keyword=Ca(2+) mobilization kn-keyword=Ca(2+) mobilization END start-ver=1.4 cd-journal=joma no-vol=106 cd-vols= no-issue=1-2 article-no= start-page=39 end-page=49 dt-received= dt-revised= dt-accepted= dt-pub-year=1994 dt-pub=199402 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The mechanism of human basophil activation associated with IgG receptor : Analysis of calcium mobilization in the human basophilic kn-title=IgGレセプターを介する好塩基球の活性化機構に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=To clarify the mechanism of human basophil activation via IgG receptors, calcium mobiliza-tion in response to IgG antibodies was analyzed in the human basophilic leukemia cell line KU812-F, using flow cytometry. KU812-F cells as well human basophils selectively expres-sed the FcγRⅡ subtype of IgG receptor. After stimulation with aggregated IgG, an obvious increase in ［Ca(2+)］i was observed, but the increase was completely inhibited by Ⅳ. 3 (antiFcγRⅡmAb). Moreover, Ⅳ. 3 elicited a［Ca(2+)］i　rise only when cross-linked on the cell surface with anti-mouse IgG. No significant histamine release was observed after any IgG stimulation and the biologic function of the FcγRⅡ-induced ［Ca(2+)］i rise remains unclar. These findings suggest that the cross-linking of FcγRⅡ in KU812-F cells induces signal transduction events and initiates cell activation with the exception of histamine release, and human basophils also may be activated in vivo by IgG antibodies. en-copyright= kn-copyright= en-aut-name=KawataNoriko en-aut-sei=Kawata en-aut-mei=Noriko kn-aut-name=河田典子 kn-aut-sei=河田 kn-aut-mei=典子 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=KU812-F kn-keyword=KU812-F en-keyword=Basophil kn-keyword=Basophil en-keyword=Ca(2+) response kn-keyword=Ca(2+) response en-keyword=FcγRⅡ kn-keyword=FcγRⅡ en-keyword=IgG antibody kn-keyword=IgG antibody END start-ver=1.4 cd-journal=joma no-vol=107 cd-vols= no-issue=9-10 article-no= start-page=195 end-page=204 dt-received= dt-revised= dt-accepted= dt-pub-year=1995 dt-pub=19951031 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Expression of β(1) integrin and fibronectin in the glomeruli in patients with glomerulonephritis kn-title=糸球体腎炎におけるβ(1)インテグリンの発現の変化の検討 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Integrins are a family of adhesion molecules which mediate adhesion and interaction between cells and extracellular matrix. The renal glomerulus is composed of cellular components and extracellular matrix.

The expression of β(1) integrin and fibronectin was increased in the mesangial area in patients with IgA nephropathy showing mesangial proliferation and mesangial matrix increase. β(1) integrin may play an important role in the construction of the glomerulus and also in the deposition of immunecomplex, proliferation of mesangial cells, and increase in extracellular matrix in IgA nephropathy. en-copyright= kn-copyright= en-aut-name=KashitaniTadatoshi en-aut-sei=Kashitani en-aut-mei=Tadatoshi kn-aut-name=柏谷忠俊 kn-aut-sei=柏谷 kn-aut-mei=忠俊 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第三内科学教室 en-keyword=β(1)インテグリン kn-keyword=β(1)インテグリン en-keyword=フィブロネクチン kn-keyword=フィブロネクチン en-keyword=lgA腎症 kn-keyword=lgA腎症 en-keyword=膜性腎症 kn-keyword=膜性腎症 END start-ver=1.4 cd-journal=joma no-vol=113 cd-vols= no-issue=3 article-no= start-page=247 end-page=259 dt-received= dt-revised= dt-accepted= dt-pub-year=2001 dt-pub=20011231 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Expression of amphiphysin Ⅰ, a nerve terminal-enriched protein, in the chromaffin cells of the rat adrenal medulla kn-title=副腎髄質のクロマフィン細胞における神経終末タンパク質 amphiphysin Ⅰの発現 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Amphiphysin (amph)Ⅰ, a protein concentrated in the nerve terminals, plays an essential role in clathrin-mediated endocytosis of synaptic vesicle membrane through an interaction with GTP ase dynamin. A speciffic antibody against amph Ⅰ revealed that the protein was also expressed in adrenal medullary cells. In the postnatal 11th day (P11) and adult rats, combined fluorescence histochemistry for catecholamine-containing cells with immunohistochemistry for amph Ⅰ disclosed strong and weak immunochemical signal of amph Ⅰ in noradrenalin (NA)- and adrenalin (A)-storing cells, respectively. Very strong immunoreactivity to amph Ⅰ was found in the intramedullary neurons but not in the adrenal cortex. In developmental stages, amph Ⅰ was discernible in the medullary chromaffin cells on 16th embryonic day (E16), E19, P0 and P2. Dopamin-β―hydroxylase (a catecholamine-synthesizing enzyme converting dopamin to noradrenalin) was immunohistochemically detected in the chromaffin cells during the parinatal periods. Colocalization of amph Ⅰ with dynamin was seen in NA-cells but not in A-cells. The present findings suggest that amph Ⅰ in the adrenal medullary NA-and A-storing cells is involved in membraine recycling mechanisms, which may be unique to each cell type, through endocytic activities. en-copyright= kn-copyright= en-aut-name=OkamotoYoko en-aut-sei=Okamoto en-aut-mei=Yoko kn-aut-name=岡本洋子 kn-aut-sei=岡本 kn-aut-mei=洋子 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=Department of Anatomy III, Okayama University Medical School en-keyword=ラット副腎髄質 kn-keyword=ラット副腎髄質 en-keyword=クロマフィン細胞 kn-keyword=クロマフィン細胞 en-keyword=amphiphysin Ⅰ kn-keyword=amphiphysin Ⅰ en-keyword=免疫組織化学 kn-keyword=免疫組織化学 END start-ver=1.4 cd-journal=joma no-vol=118 cd-vols= no-issue=3 article-no= start-page=225 end-page=234 dt-received= dt-revised= dt-accepted= dt-pub-year=2007 dt-pub=20070104 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=3-ニトロチロシン en-subtitle= kn-subtitle= en-abstract= kn-abstract=種々の機序により産生された活性窒素種 (reactive nitrogen species) によるチロシン残基のニトロ化による3-ニトロチロシン (3-NT) の生成は, 蛋白質の翻訳後修飾の一つとして広く認められている.種々の炎症性疾患組織では, 一酸化窒素・二酸化窒素・ペルオキシナイトライトといった活性窒素種が異なる機序で産生され, 3-NTの産生に関与している. チロシンニトロ化蛋白質の同定や, 蛋白質分子中のチロシンニトロ化部位が決定できるようになり, 蛋白質の寿命, 蛋白質問相互作用に対する悪影響, 蛋白質機能喪失との関連づけが可能になってきた. 測定法としては, 免疫組織化学的手法, ウェスタンブロッティングによる半定量法から, ELISA, HPLC-ECD, LC-MS/MS, GC-MS/MSを用いた定量的な方法がある. 本総説では, 3-NTについて, その生成機序, 測定方法, 予防医学的応用を述べる. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=荻野景規 kn-aut-sei=荻野 kn-aut-mei=景規 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　公衆衛生学 en-keyword=3ﾝニトロチロシン kn-keyword=3ﾝニトロチロシン en-keyword=活性窒素種 kn-keyword=活性窒素種 en-keyword=翻訳後修飾 kn-keyword=翻訳後修飾 END
