This study found that, when primary fibroblast AG1522 cells on confluent were irradiated with a 100 keV/um carbon-ion beam, the cell responses of micronuclei (MN) formation and G1-phase arrest had a low dose sensitivity effect that was positively regulated by the GJIC. Meanwhile, when neoplastic human salivary gland (HSG) cells were irradiated under the condition of confluent but with poor internal GJIC, MN and G2-phase arrest were induced. Unexpectedly, when GJIC between HSG cells were enhanced by treating of cells with 8-Br-CAMP, these radiation-induced cellular damage was reduced so that cell surviving fraction was slightly enhanced, suggesting that increased GJIC protects HSG cells from lethal radiation damage. Further investigation demonstrated that ROS were involved in the GJIC-enhanced radiation effect on AG1522 cells and nitric oxide contributed to the GJIC-reduced radiation effect on HSG 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":"日本放射線影響学会第50回大会","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":"邵, 春林"}],"nameIdentifiers":[{"nameIdentifier":"616470","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"古澤, 佳也"}],"nameIdentifiers":[{"nameIdentifier":"616471","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"松本, 孔貴"}],"nameIdentifiers":[{"nameIdentifier":"616472","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"陳, 紅紅"}],"nameIdentifiers":[{"nameIdentifier":"616473","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"古澤 佳也","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"616474","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"松本 孔貴","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"616475","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":"放射線応答に対するGJICの役割は繊維芽細胞と癌細胞で異なる","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"放射線応答に対するGJICの役割は繊維芽細胞と癌細胞で異なる"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-12-17"},"publish_date":"2007-12-17","publish_status":"0","recid":"62367","relation_version_is_last":true,"title":["放射線応答に対するGJICの役割は繊維芽細胞と癌細胞で異なる"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T21:31:35.362346+00:00"}
