Previously, we suggested that myeloperoxidase (MPO) was the key enzyme because it promotes generation of powerful oxidant  hypochlorous acid which reacting with DNA. In our study, using a whole-human-genome oligonucleotide microarray, we analyzed the genome-wide expression profiles of  HL60 human promyelocytic cell lines exposed to 1,2,4-benzenetriol (BT) with or without MPO inhibition. The microarray analysis revealed that 4h exposure to BT changed the expressionin  HL60 cells of 1213 genes associated with transcription, RNA metabolic processes, immuneresponse, apoptosis, cell death, and biosynthetic processes, and that these changes were dramatically lessened by MPO-specific inhibition. Gene expression profiles along with GO and KEGG pathway annotation analysis suggest that there maybe a role for MPO as an examination marker or in prophylaxis forchemical carcinogenesis.","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":"24790602"}]},"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":[{"creatorNames":[{"creatorName":"西川, 拓朗","creatorNameLang":"ja"},{"creatorName":"ニシカワ, タクロウ","creatorNameLang":"ja-Kana"},{"creatorName":"NISHIKAWA, Takuro","creatorNameLang":"en"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-28"}],"displaytype":"detail","filename":"24790602_nishikawa.pdf","filesize":[{"value":"3.2 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"24790602_nishikawa.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/8997/files/24790602_nishikawa.pdf"},"version_id":"5c66fa11-ee91-4554-ab8d-3b6b9c6cdaf5"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ベンゼン","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"発がん","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"ミエロペルオキシダーゼ","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"活性酸素","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"マイクロアレイ","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"急性骨髄性白血病","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":"MPO阻害剤によるベンゼン・放射線誘導骨髄障害、AML発がんの予防","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"MPO阻害剤によるベンゼン・放射線誘導骨髄障害、AML発がんの予防","subitem_title_language":"ja"},{"subitem_title":"Prevention of benzene (or radiation) induced acute myeloid leukemia (or bone marrow failure) by myeloperoxidase inhibitor","subitem_title_language":"en"}]},"item_type_id":"8","owner":"18","path":["100"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2015-05-19"},"publish_date":"2015-05-19","publish_status":"0","recid":"8997","relation_version_is_last":true,"title":["MPO阻害剤によるベンゼン・放射線誘導骨髄障害、AML発がんの予防"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-04-24T05:47:05.269596+00:00"}
