The IAP RNA is reversely transcribed and the cDNA is inserted into genomic DNA by the retrotransposition mechanism. Since functions of the gene at or nearby the novel insertion site of IAP cDNA are modified, the IAP element is presumable as endogenous mutagen. We found that genomic DNA rearrangement by the IAP-mediated retrotransposition is augmented in the myeloid leukemia cells in C3H/He inbred mouse.\nRadiation-induced tumors are originated from cells in regenerated tissues after serious damages by ionizing radiation. In the regenerated myeloid cells following irradiation of sublethal doses at 3Gys of x-ray, the transcription level of a limited type among structural variants of the IAP elements in the genome were increased. Rearrangements of genomic DNA by unique insertions of the limited type of IAP cDNA are found in all the cell lines of acute myeloid leukemia induced by the radiation. This type of retrotransposition was observed in limited cell lines of radiation-induced thymic lymphoma and was hardly detected in the cells of non-hematopoietic tumor including skin carcinoma and hepatic tumors. Similar activation was not observed in the most types of IAP element. These findings indicate that an activation of the limited type of IAP element by radiation damage contributes to the genomic instability in the myeloid cells in C3H.","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 2nd International Workshop on Space 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":"Ishihara, Hiroshi"}],"nameIdentifiers":[{"nameIdentifier":"660513","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tanaka, Izumi"}],"nameIdentifiers":[{"nameIdentifier":"660514","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nojima, Kumie"}],"nameIdentifiers":[{"nameIdentifier":"660515","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Furuse, Masako"}],"nameIdentifiers":[{"nameIdentifier":"660516","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shimada, Yoshiya"}],"nameIdentifiers":[{"nameIdentifier":"660517","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nishimura, Mayumi"}],"nameIdentifiers":[{"nameIdentifier":"660518","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshinaga, Yuko"}],"nameIdentifiers":[{"nameIdentifier":"660519","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"石原 弘","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"660520","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田中 泉","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"660521","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"野島 久美恵","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"660522","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"古瀬 雅子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"660523","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"島田 義也","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"660524","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"西村 まゆみ","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"660525","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":"Frequent Rearrangement of Genomic DNA by an Endogeneous Retrovirus in Radiation-induced Myeloid Leukemia Cells of C3H/He Inbred Mice","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Frequent Rearrangement of Genomic DNA by an Endogeneous Retrovirus in Radiation-induced Myeloid Leukemia Cells of C3H/He Inbred Mice"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2002-06-10"},"publish_date":"2002-06-10","publish_status":"0","recid":"67189","relation_version_is_last":true,"title":["Frequent Rearrangement of Genomic DNA by an Endogeneous Retrovirus in Radiation-induced Myeloid Leukemia Cells of C3H/He Inbred Mice"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:40:36.296811+00:00"}
