Mathematical analysis suggested an additive increase when IR and chemicals were combined. Hras mutations were characteristic of carcinomas induced by chemicals and were overrepresented in carcinomas induced by the combination of IR and MNU, suggesting their interaction at the initiation level. Comprehensive screening using microarrays failed to identify differences in gene expression among carcinomas induced by different treatments. \nConclusion: A complex interaction may underlie the combined effect of IR and carcinogenic chemicals in the experimental model.","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":"第72回日本癌学会学術総会","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":"Imaoka, Tatsuhiko"}],"nameIdentifiers":[{"nameIdentifier":"700723","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nishimura, Mayumi"}],"nameIdentifiers":[{"nameIdentifier":"700724","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ishikawa, Kenichi"}],"nameIdentifiers":[{"nameIdentifier":"700725","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamashita, Satoshi"}],"nameIdentifiers":[{"nameIdentifier":"700726","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ushijima, Toshikazu"}],"nameIdentifiers":[{"nameIdentifier":"700727","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Imai, Takashi"}],"nameIdentifiers":[{"nameIdentifier":"700728","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shimada, Yoshiya"}],"nameIdentifiers":[{"nameIdentifier":"700729","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"今岡 達彦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"700730","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"西村 まゆみ","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"700731","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"石川 顕一","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"700732","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"今井 高志","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"700733","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"島田 義也","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"700734","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":"Complex interactions between ionizing radiation and carcinogenic chemicals on rat mammary carcinogenesis","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Complex interactions between ionizing radiation and carcinogenic chemicals on rat mammary carcinogenesis"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-10-07"},"publish_date":"2013-10-07","publish_status":"0","recid":"71277","relation_version_is_last":true,"title":["Complex interactions between ionizing radiation and carcinogenic chemicals on rat mammary carcinogenesis"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:53:06.838761+00:00"}
