The spermatozoa were treated in vitro with the DNA-damaging agents, methyl methanesulfonate (MMS) or hydrogen peroxide (H2O2), and then embedded in agarose gel on glass slides. The slides were immersed in alkaline solution (>pH 13) for 1, 5, 10 and 20 min, and then subjected to the electrophoresis under neutral conditions. In mouse spermatozoa, comet tails seen in solvent controls became brighter and longer as the alkaline DNA unwinding time increased. However, in the MMS-treated mouse spermatozoa, a smaller difference in the damage from that in the solvent control was seen with time within a dose. DNA damage induced by H2O2 could also be detected accurately after alkali treatment for 1–20 min. In human spermatozoa, DNA damage induced by MMS and H2O2 could be detected in a dose-dependent manner after alkali treatment for 1 min. The ability of the comet assay to detect DNA damage was not adversely affected by the short period (1 min) of the alkaline DNA unwinding time.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_5_description_36":{"attribute_name":"注記","attribute_value_mlt":[{"subitem_description":"http://dx.doi.org/10.1038/aja.2010.105","subitem_description_type":"Other"}]},"item_5_description_37":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_5_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_5_relation_24":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1038/aja.2010.105","subitem_relation_type_select":"DOI"}}]},"item_5_source_id_22":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1008-682X","subitem_source_identifier_type":"PISSN"}]},"item_5_text_44":{"attribute_name":"ID(XooNIps)","attribute_value_mlt":[{"subitem_text_value":"21057514"}]},"item_5_text_54":{"attribute_name":"閲覧数(XooNIps)","attribute_value_mlt":[{"subitem_text_value":"1073"}]},"item_5_text_55":{"attribute_name":"ダウンロード数(XooNIps)","attribute_value_mlt":[{"subitem_text_value":"995"}]},"item_5_version_type_38":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"日下部, 博一","creatorNameLang":"ja"},{"creatorName":"クサカベ, ヒロカズ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"12285","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tateno, Hiroyuki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"12286","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":"2021-07-06"}],"displaytype":"detail","filename":"4494.pdf","filesize":[{"value":"187.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"4494.pdf","url":"https://asahikawa-med.repo.nii.ac.jp/record/4040/files/4494.pdf"},"version_id":"0603e33d-1688-4355-80d6-b21747b87d9e"}]},"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":"Shortening of alkaline DNA unwinding time does not interfere with detecting DNA damage to mouse and human spermatozoa in the comet assay","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Shortening of alkaline DNA unwinding time does not interfere with detecting DNA damage to mouse and human spermatozoa in the comet assay","subitem_title_language":"en"}]},"item_type_id":"5","owner":"3","path":["6","7","24"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2012-05-17"},"publish_date":"2012-05-17","publish_status":"0","recid":"4040","relation_version_is_last":true,"title":["Shortening of alkaline DNA unwinding time does not interfere with detecting DNA damage to mouse and human spermatozoa in the comet assay"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2024-07-30T01:30:19.177678+00:00"}
