However, the in vivo anti-estrogenic effects of menadione have not been determined, while correlations between biological effects and structural changes are unclear. Thus, we investigated the in vivo anti-estrogenic activity of menadione under fluorescent light and dark conditions. Suppression of the hepatic estrogen response genes vitellogenin1 (VTG1), VTG2 and estrogen receptor-α (ER-α) was used as an index of antiestrogenic activity. Male medaka (Oryzias latipes) were treated with nominal concentrations of menadione in the presence or absence of 17β-estradiol (E2), and hepatic VTG1, VTG2 and ER-α mRNA levels were determined by quantitative real-time PCR. In the presence of E2 under dark conditions, expression of hepatic VTG2 and ER-α genes was suppressed by menadione treatment. On the other hand, menadione activity was lost under fluorescent light conditions. These results suggest that menadione has antiestrogenic activity in vivo, and that this activity is diminished under fluorescent light, probably due to a structural change in menadione.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Journal of Health Science, 54(5), pp.596-601; 2008","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Pharmaceutical Society of Japan"}]},"item_2_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1248/jhs.54.596","subitem_relation_type_select":"DOI"}}]},"item_2_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11316464","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13449702","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_16":{"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":[{"creatorNames":[{"creatorName":"Yamaguchi, Akemi"}],"nameIdentifiers":[{"nameIdentifier":"73318","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kohra, Shinya"}],"nameIdentifiers":[{"nameIdentifier":"73319","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ishibashi, Hiroshi"}],"nameIdentifiers":[{"nameIdentifier":"73320","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Arizono, Koji"}],"nameIdentifiers":[{"nameIdentifier":"73321","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tominaga, Nobuaki"}],"nameIdentifiers":[{"nameIdentifier":"73322","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-23"}],"displaytype":"detail","filename":"JHS54_596.pdf","filesize":[{"value":"276.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"JHS54_596.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/18356/files/JHS54_596.pdf"},"version_id":"fb748646-23ae-4c1a-a8c9-5ff333c810b2"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"menadione","subitem_subject_scheme":"Other"},{"subitem_subject":"anti-estrogenic","subitem_subject_scheme":"Other"},{"subitem_subject":"oryzias latipes, in vivo","subitem_subject_scheme":"Other"}]},"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":"In Vivo Anti-estrogenic Effects of Menadione on Hepatic Estrogen-responsive Gene Expression in Male Medaka (Oryzias latipes)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"In Vivo Anti-estrogenic Effects of Menadione on Hepatic Estrogen-responsive Gene Expression in Male Medaka (Oryzias latipes)"}]},"item_type_id":"2","owner":"2","path":["56"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-11-14"},"publish_date":"2008-11-14","publish_status":"0","recid":"18356","relation_version_is_last":true,"title":["In Vivo Anti-estrogenic Effects of Menadione on Hepatic Estrogen-responsive Gene Expression in Male Medaka (Oryzias latipes)"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T03:59:11.076259+00:00"}
