Twenty-five patients were treated with radiotherapy (RT) alone, while 28 received the same radiotherapy plus concomitant chemotherapy with cisplatin (CRT). Changes in gene expression induced by treatment were investigated using CodeLink single-color oligo-microarrays consisting of 44K human sequences. Paraffin-embedded samples were used to examine apoptosis and the expression of protein related with treatment-responsive genes. Changes in mRNA expression were assessed for these genes by real-time reverse transcriptase-polymerase chain reaction. \nResults: We found several tens of genes, including CDKN1A, BAX, TNFSF8, RRM2B, and FGF2, responded to CRT using microarray analysis, and suggested CRT activated TNF-mediated cell death pathway and extra-cellular matrix pathway related with cell death pathway. Apoptotic cells were significantly increased in both groups. In immunohistochemical study, CRT significantly increased the numbers of cases with diffusely distributed CDKN1A-positive cells (P < 0.002). Protein expression of ICAD was recognized weakly in nucleus of tumor cells in pre-treatment samples and decreased significantly after CRT (P < 0.05). BAK1 increased its intensity in half of cases at mid-treatment. The expression changes of FGF2 were revealed to be significantly different between good responders and poor responders (P < 0.05). \nConclusions: CRT produced a homogenous pattern of changes in expression of known radiation-responsive genes. Our data suggest that concurrent use of cisplatin produced a radiosensitizing effect in most of these cervical cancer patients. Microarray analysis appeared a useful tool to get a comprehensive overview of the changes in gene expression after irradiation. In addition, transcriptional profiling of sequential biopsies after irradiation would improve our understanding of the biological effectiveness of radiotherapy, and provide information on potential targets for adjuvant therapy.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"The 13th International Congress of Radiation Research","subitem_description_type":"Other"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Iwakawa, Mayumi"}],"nameIdentifiers":[{"nameIdentifier":"677390","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ohno, Tatsuya"}],"nameIdentifiers":[{"nameIdentifier":"677391","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Imadome, Kaori"}],"nameIdentifiers":[{"nameIdentifier":"677392","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakawatari, Miyako"}],"nameIdentifiers":[{"nameIdentifier":"677393","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sakai, Minako"}],"nameIdentifiers":[{"nameIdentifier":"677394","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Moritake, Takashi"}],"nameIdentifiers":[{"nameIdentifier":"677395","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakamura, Etsuko"}],"nameIdentifiers":[{"nameIdentifier":"677396","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tamaki, Tomoaki"}],"nameIdentifiers":[{"nameIdentifier":"677397","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Katoh, Shingo"}],"nameIdentifiers":[{"nameIdentifier":"677398","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tsujii, Hirohiko"}],"nameIdentifiers":[{"nameIdentifier":"677399","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Imai, Takashi"}],"nameIdentifiers":[{"nameIdentifier":"677400","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"岩川 眞由美","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"677401","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"大野 達也","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"677402","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"今留 香織","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"677403","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中渡 美也子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"677404","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"酒井 美奈子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"677405","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"盛武 敬","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"677406","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田巻 倫明","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"677407","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"加藤 眞吾","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"677408","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"辻井 博彦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"677409","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"今井 高志","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"677410","nameIdentifierScheme":"WEKO"}]}]},"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":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"TNF-mediated cell-death signaling pathway and extracellular matrix pathway are activated by concurrent use of cisplatin with radiotherapy in sequential biopsy specimens from patients with cervical cancer.","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"TNF-mediated cell-death signaling pathway and extracellular matrix pathway are activated by concurrent use of cisplatin with radiotherapy in sequential biopsy specimens from patients with cervical cancer."}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-07-17"},"publish_date":"2007-07-17","publish_status":"0","recid":"69022","relation_version_is_last":true,"title":["TNF-mediated cell-death signaling pathway and extracellular matrix pathway are activated by concurrent use of cisplatin with radiotherapy in sequential biopsy specimens from patients with cervical cancer."],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:19:25.031160+00:00"}
