We found SCAN1 is caused by a specific point mutation the tyrosyl-DNA phosphodiesterase (TDP1) gene. Functional and genetic studies suggest that this mutation, which disrupts the active site of the Tdp1 enzyme, causes disease by a combination of decreased catalytic activity and stabilization of the normally transient covalent Tdp1-DNA intermediate. The Tdp1 knockout mice showed the retinitis pigmentosa like phenotype. The RNA expressions were mostly normal in the microarray studies of Tdp1 knockout mice. These findings make spurred understanding of DNA repair in human biology and suggested a novel mechanism of human disease.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_8_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学","subitem_publisher_language":"ja"},{"subitem_publisher":"Kagoshima University","subitem_publisher_language":"en"}]},"item_8_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"493","subitem_subject_scheme":"NDC"}]},"item_8_text_41":{"attribute_name":"科研費番号 ","attribute_value_mlt":[{"subitem_text_value":"21591095"}]},"item_8_version_type_14":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAlternatives":[{"creatorAlternative":"髙嶋, 博","creatorAlternativeLang":"ja"}],"creatorNames":[{"creatorName":"高嶋, 博","creatorNameLang":"ja"},{"creatorName":"TAKASHIMA, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"5469","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000080372803","nameIdentifierScheme":"NRID","nameIdentifierURI":" "}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-27"}],"displaytype":"detail","filename":"21591095seika.pdf","filesize":[{"value":"285.8 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"21591095seika.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/861/files/21591095seika.pdf"},"version_id":"5ad8bea4-5ba9-41f7-99fd-561c8798101b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"SCAN1","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Tdp1","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"SSBR","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"末梢神経障害","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"一本鎖DNA修復","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"ノックアウトマウス","subitem_subject_language":"ja","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"一本鎖DNA修復異常症SCAN1の神経変性機構の解明","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"一本鎖DNA修復異常症SCAN1の神経変性機構の解明","subitem_title_language":"ja"},{"subitem_title":"Pathomechanism of spinocereballar ataxia with axonal neuropathy (SCAN1) -DNA single strand break repair and neurodegeneration","subitem_title_language":"en"}]},"item_type_id":"8","owner":"18","path":["80"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2014-12-22"},"publish_date":"2014-12-22","publish_status":"0","recid":"861","relation_version_is_last":true,"title":["一本鎖DNA修復異常症SCAN1の神経変性機構の解明"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-05-24T00:24:08.631434+00:00"}
