It is of interest to understand biological consequences of the heterozygotic state by functionally distinct, homologous haploid chromosomes within a nucleus of cells in the patients. To this end, diplotype of these chromosomes must be precisely determined to evaluate their clinical outcomes. \n\\nMETHODS: In this study, a novel methodology of long-range (over 20 kb) haplotype determination involving sensitive amplification of single DNA molecules within agarose gels has been developed. Limited dilution of DNA molecules was performed in heated alkaline agarose solution, avoiding extensive shearing and aggregation during dilution process. Aliquoting the gel solution provided physical separation of DNA molecules derived from homologous chromosomes. The solidified agarose gel pieces were then treated by exogenously supplied Phi29 DNA polymerase and random hexamer oligonucleotides, yielding up to 120,000-fold multiple-displacement amplification of the gel-embedded DNA molecules. The amplified materials were recovered in solution as PCR-ready form by simple heating, making them conveniently available for further multiple locus genotyping. \n\\nRESULTS: and CONCLUSIONS Feasibility of this methodology for isolating long-range single DNA molecules spanning the selected SNP markers (PTTG1: 20 kb, CD44: 80 kb) was further confirmed using DNAs derived from patients with heterozygotic state. Thus, the haploid chromosomes distinguished by the SNP markers of the above clinical radiation sensitivity-associated genes can now be successfully determined in the individual breast cancer patients.","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":"48ｔｈ the American Society for Cell Biology Annual Meeting","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":"Michikawa, Yuichi"}],"nameIdentifiers":[{"nameIdentifier":"683962","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Noshiro, Katsuko"}],"nameIdentifiers":[{"nameIdentifier":"683963","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Suga, Tomo"}],"nameIdentifiers":[{"nameIdentifier":"683964","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ishikawa, Atsuko"}],"nameIdentifiers":[{"nameIdentifier":"683965","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shoji, Yoshimi"}],"nameIdentifiers":[{"nameIdentifier":"683966","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Iwakawa, Mayumi"}],"nameIdentifiers":[{"nameIdentifier":"683967","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Imai, Takashi"}],"nameIdentifiers":[{"nameIdentifier":"683968","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"道川 祐市","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"683969","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"野代 勝子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"683970","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"菅 智","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"683971","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"石川 敦子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"683972","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"荘司 好美","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"683973","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"岩川 眞由美","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"683974","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"今井 高志","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"683975","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":"Long-range single DNA molecule haplotyping of human clinical radiation sensitivity-associated genes (PTTG1 and CD44)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Long-range single DNA molecule haplotyping of human clinical radiation sensitivity-associated genes (PTTG1 and CD44)"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-01-27"},"publish_date":"2009-01-27","publish_status":"0","recid":"69676","relation_version_is_last":true,"title":["Long-range single DNA molecule haplotyping of human clinical radiation sensitivity-associated genes (PTTG1 and CD44)"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:11:42.091731+00:00"}
