It is one of the more effective drugs to sensitize cells for radiation and its radio-sensitizing properties were demonstrated both in vivo and in vitro. Yet, the exact interaction of dFdC and radiation has not been elucidated. In this study, we examined the mechanisms by using 10 MV Lineac-X-irradiation on culture mammalian cells. A repair deficient clone, xrs5 cell line was used in addition to wild type rodent cell line (CHO). The sensitivity to each irradiation or dFdC on cells was evaluated by colony formation assay, and much higher cell killing effects were observed. To learn about the mechanism more, we examined p-53-binding protein 1 (53BP1) focus formation by the immunofluorescent method, which is known as a method for the detection of DNA double-strand breaks (DSBs). The results showed that the treatment of dFdC alone could induce 53BP1 foci, suggesting that DNA DSBs are induced by dFdC independently. When cells were irradiated after the dFdC treatment, enhanced cell-killing effects were observed in CHO cells but not in xrs5. These results strongly suggest that dFdC inhibit the repair for DNA DSBs.","subitem_description_type":"Other"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"純真学園大学"}]},"item_10002_relation_12":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"40020087030","subitem_relation_type_select":"NAID"}}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12581584","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2186-6481","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"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":"MORIKAWA, Keiko"},{"creatorName":"MORIKAWA, Keiko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"134","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"9000250171828 ","nameIdentifierScheme":"CiNii ID","nameIdentifierURI":"http://ci.nii.ac.jp/nrid/9000250171828 "}]},{"creatorNames":[{"creatorName":"KASHINO, Genro"},{"creatorName":"KASHINO, Genro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"135","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"9000250171829 ","nameIdentifierScheme":"CiNii ID","nameIdentifierURI":"http://ci.nii.ac.jp/nrid/9000250171829 "}]},{"creatorNames":[{"creatorName":"MORI, Hiromu"}],"nameIdentifiers":[{"nameIdentifier":"136","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"9000250171830","nameIdentifierScheme":"CiNii ID","nameIdentifierURI":"http://ci.nii.ac.jp/nrid/9000250171830"}]},{"creatorNames":[{"creatorName":"MORI, Hiromu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"137","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"9000250171830 ","nameIdentifierScheme":"CiNii ID","nameIdentifierURI":"http://ci.nii.ac.jp/nrid/9000250171830 "}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-11"}],"displaytype":"detail","filename":"純真学園大学雑誌-03号_p053-059.pdf","filesize":[{"value":"992.0 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"純真学園大学雑誌-03号_p053-059","url":"https://junshin.repo.nii.ac.jp/record/91/files/純真学園大学雑誌-03号_p053-059.pdf"},"version_id":"a900de75-c10e-4c14-9829-c0f5c43efcc8"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"gemcitabine","subitem_subject_scheme":"Other"},{"subitem_subject":"radiosensitization","subitem_subject_scheme":"Other"},{"subitem_subject":"CHO","subitem_subject_scheme":"Other"},{"subitem_subject":"xrs5","subitem_subject_scheme":"Other"},{"subitem_subject":"DNA","subitem_subject_scheme":"Other"},{"subitem_subject":"DSBs","subitem_subject_scheme":"Other"},{"subitem_subject":"gemcitabine","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"radiosensitization","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"CHO","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"xrs5","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"DNA","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"DSBs","subitem_subject_language":"en","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"The effect of radiosensitization by gemcitabine on mammalian cells","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"The effect of radiosensitization by gemcitabine on mammalian cells"},{"subitem_title":"The effect of radiosensitization by gemcitabine on mammalian cells","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"12","path":["15"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-10-11"},"publish_date":"2016-10-11","publish_status":"0","recid":"91","relation_version_is_last":true,"title":["The effect of radiosensitization by gemcitabine on mammalian cells"],"weko_creator_id":"12","weko_shared_id":-1},"updated":"2023-05-15T15:42:15.674009+00:00"}
