Thus our results reveal that Oct-1 is crucial to the TP53-mediated regulation of the CDKN1A gene promoter following exposure to clinically relevant doses of IR.","subitem_description_type":"Abstract"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.bbagrm.2008.12.002","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1874-9399","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Nenoi, Mitsuru"}],"nameIdentifiers":[{"nameIdentifier":"452046","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Daino, Kazuhiro"}],"nameIdentifiers":[{"nameIdentifier":"452047","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakajima, Tetsuo"}],"nameIdentifiers":[{"nameIdentifier":"452048","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Bing, Wang"}],"nameIdentifiers":[{"nameIdentifier":"452049","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Taki, Keiko"}],"nameIdentifiers":[{"nameIdentifier":"452050","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kakimoto, Ayana"}],"nameIdentifiers":[{"nameIdentifier":"452051","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"根井 充","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"452052","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"臺野 和広","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"452053","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中島 徹夫","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"452054","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"王 冰","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"452055","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"瀧 景子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"452056","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"柿本 彩七","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"452057","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Involvement of Oct-1 in the regulation of CDKN1A in response to clinically relevant doses of ionizing radiation","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Involvement of Oct-1 in the regulation of CDKN1A in response to clinically relevant doses of ionizing radiation"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-04-23"},"publish_date":"2009-04-23","publish_status":"0","recid":"45495","relation_version_is_last":true,"title":["Involvement of Oct-1 in the regulation of CDKN1A in response to clinically relevant doses of ionizing radiation"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T00:03:04.468245+00:00"}
