We investigated the effect of chemotherapeutic drugs on DR4-mediated apoptosis in human bladder cancer cells, using a human monoclonal agonistic antibody specific for DR4, mapatumumab. Cytotoxicity was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Synergy was assessed by isobolographic analysis. Treatment of human bladder cancer T24 cells with mapatumumab in combination with mitomycin C, vinblastine or gemcitabine did not overcome resistance to these agents. However, treatment with mapatumumab in combination with epirubicin (EPI) had a synergistic cytotoxic effect. Synergy was also obtained in KU7 and RT112 human bladder cancer cells. A synergistic effect was also observed with mapatumumab in combination with pirarubicin. The synergy obtained in cytotoxicity with mapatumumab and EPI was also achieved in apoptosis. EPI markedly increased DR4 expression in the bladder cancer cells at both the mRNA and protein levels. Furthermore, the combination-induced cytotoxicity was significantly suppressed by the DR4:Fc chimeric protein. The combination of EPI and mapatumumab significantly activated the caspase cascade, including caspase-8, -9 and -3, which are the downstream molecules of death receptors. These findings indicate that EPI sensitizes bladder cancer cells to DR4-mediated apoptosis through induction of DR4 and activation of caspases, suggesting that the combination therapy of EPI and mapatumumab may be effective for bladder cancer therapy.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10006_dissertation_number_12":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第603号"}]},"item_10006_relation_15":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.3892/or.2014.3654","subitem_relation_type_select":"DOI"}},{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://dl.ndl.go.jp/pid/11344363","subitem_relation_type_select":"URI"}}]},"item_10006_relation_22":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"25483927","subitem_relation_type_select":"PMID"}}]},"item_10006_relation_28":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"500001358799","subitem_relation_type_select":"NAID"}}]},"item_10006_text_30":{"attribute_name":"KEID","attribute_value_mlt":[{"subitem_text_value":"27642"}]},"item_10006_version_type_18":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_fa2ee174bc00049f","subitem_version_type":"P"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Ahmed, Syed Minhaj Uddin","creatorNameLang":"ja"},{"creatorName":"Ahmed, Syed Minhaj Uddin","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"3150","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"8000001664234 ","nameIdentifierScheme":"CiNii ID","nameIdentifierURI":"http://ci.nii.ac.jp/nrid/8000001664234 "}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-10-27"}],"displaytype":"detail","filename":"Med_A603.pdf","filesize":[{"value":"1.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文","objectType":"fulltext","url":"https://kagawa-u.repo.nii.ac.jp/record/235/files/Med_A603.pdf"},"version_id":"cf0306f1-b829-4244-bc82-1c26de47691d"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-10-27"}],"displaytype":"detail","filename":"Med_A603_abstract.pdf","filesize":[{"value":"64.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"内容の要旨","objectType":"abstract","url":"https://kagawa-u.repo.nii.ac.jp/record/235/files/Med_A603_abstract.pdf"},"version_id":"a120dbdc-6def-4d4e-bdc6-9776fd80d2c6"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-10-27"}],"displaytype":"detail","filename":"Med_A603_result.pdf","filesize":[{"value":"86.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"審査の結果の要旨","objectType":"other","url":"https://kagawa-u.repo.nii.ac.jp/record/235/files/Med_A603_result.pdf"},"version_id":"11d82082-f8b6-472d-8d49-f2b3a3041ad1"}]},"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":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"Synergistic induction of apoptosis by mapatumumab and anthracyclines in human bladder cancer cells","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Synergistic induction of apoptosis by mapatumumab and anthracyclines in human bladder cancer cells","subitem_title_language":"en"}]},"item_type_id":"10006","owner":"11","path":["40"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2019-07-31"},"publish_date":"2019-07-31","publish_status":"0","recid":"235","relation_version_is_last":true,"title":["Synergistic induction of apoptosis by mapatumumab and anthracyclines in human bladder cancer cells"],"weko_creator_id":"11","weko_shared_id":-1},"updated":"2024-10-31T07:58:46.548496+00:00"}
