We used p53 null H1299 cells transfected with wild-type p53(wtp53) or mutated p53(mp53) gene. We found\nthat (i) there was no significant difference in sensitivity to high LET radiations above 30 KeV/um among H1299, H1299/mp53 and H1299/wtp53 cells, although the radiosensitivity of H1299/wtp53 cells against X-rays was higher (1.2-fold) than those of H1299 and H1299/mp53 cells; (ii) there was an synergistic enhancement with heat to radiosensitivity against below 70 KeV/um in H1299/ wtp53 cells alone; (iii) low-LET radiations effectively induced apoptosis in H1299/wtp53 cells as compared with H1299 and H1299/mp53 cells; (iv) high-LET radiations as compared with low-LET radiation at iso-survival dose effectively induced apoptosis in H1299/wtp53 cells; (v) high-LET radiations induced p53-independent apoptosis in H1299 and H1299/mp53 cells; (vi) thermal enhancement of cellular sensitivity against X-ray might be due to induction of p53-dependent apoptosis. Our findings suggest that thermal enhancement of radiosensitivity may be resulted in p53-dependent apoptosis instead ofinhibition of p53-dependent cell survival system(s)through either regulation of the cell cycle orinduction of DNA repair.","subitem_description_type":"Abstract"}]},"item_10004_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"放医研"}]},"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":"大西, 武雄"}],"nameIdentifiers":[{"nameIdentifier":"564979","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"高橋, 昭久"}],"nameIdentifiers":[{"nameIdentifier":"564980","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"浅川, 勇雄"}],"nameIdentifiers":[{"nameIdentifier":"564981","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"大西, 健"}],"nameIdentifiers":[{"nameIdentifier":"564982","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"玉本, 哲朗"}],"nameIdentifiers":[{"nameIdentifier":"564983","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"古澤, 佳也"}],"nameIdentifiers":[{"nameIdentifier":"564984","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"大西 武雄","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"564985","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"高橋 昭久","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"564986","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"浅川 勇雄","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"564987","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"大西 健","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"564988","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"玉本 哲郎","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"564989","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"古澤 佳也","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"564990","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":"article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"癌関連遺伝子からみた重粒子線治療の基礎的研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"癌関連遺伝子からみた重粒子線治療の基礎的研究"}]},"item_type_id":"10004","owner":"1","path":["7"],"pubdate":{"attribute_name":"公開日","attribute_value":"2004-01-23"},"publish_date":"2004-01-23","publish_status":"0","recid":"55235","relation_version_is_last":true,"title":["癌関連遺伝子からみた重粒子線治療の基礎的研究"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T22:51:52.346260+00:00"}
