To establish the C-ion resistant cancer model, we repeatedly irradiated in vivo the mouse squamous cell carcinoma cell line NRS1, SCCVII, and mouse mammary carcinoma cell MCa4 with 290 MeV/n of C-ion. In the presence, the NRS1 and MCa4 cell were respectively irradiated with 60Gy and 75Gy for total dose. We will irradiate these tumors until 90Gy. While we irradiated SCCVII cell with single dose 15Gy of C-ion and then transplanted into another mouse after 2 weeks of irradiation, tumor is no longer grown. In vitro, we established the NRS1-C30 cell by the irradiation with total dose 30Gy of C-ion. We will elucidate whither C-ion and X-ray resistance is generated in NRS1-C30 cell. To compare the mechanisms of C-ion resistance with that of X-ray resistance, we established the X-ray resistant NRS1-X60 cell in vitro by the repeated X-ray irradiations. Surprisingly, NRS1-X60 cell is 23-folds resistance to C-ion compared with NRS1. However, the RBE of C-ion at D10 is approximately same in both cells.","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":"平成24年度HIMAC共同利用研究成果発表会","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":"佐藤, 克俊"}],"nameIdentifiers":[{"nameIdentifier":"640328","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"下川, 卓志"}],"nameIdentifiers":[{"nameIdentifier":"640329","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"入江, 大介"}],"nameIdentifiers":[{"nameIdentifier":"640330","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中渡, 美也子"}],"nameIdentifiers":[{"nameIdentifier":"640331","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中村, 悦子"}],"nameIdentifiers":[{"nameIdentifier":"640332","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"森竹, 浩之"}],"nameIdentifiers":[{"nameIdentifier":"640333","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"今井, 高志"}],"nameIdentifiers":[{"nameIdentifier":"640334","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"佐藤 克俊","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"640335","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"下川 卓志","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"640336","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"入江 大介","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"640337","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中渡 美也子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"640338","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中村 悦子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"640339","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"森竹 浩之","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"640340","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"今井 高志","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"640341","nameIdentifierScheme":"WEKO"}]}]},"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":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"局所再発腫瘍における炭素イオン線抵抗性獲得とそれに伴う転移に関わる性質変化に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"局所再発腫瘍における炭素イオン線抵抗性獲得とそれに伴う転移に関わる性質変化に関する研究"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-04-30"},"publish_date":"2013-04-30","publish_status":"0","recid":"64983","relation_version_is_last":true,"title":["局所再発腫瘍における炭素イオン線抵抗性獲得とそれに伴う転移に関わる性質変化に関する研究"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T21:05:22.776607+00:00"}
