The CD10-negative immunophenotype of infant ALL is a hallmark and provides a predictable signature of mixed-lineage leukemia (MLL) rearrangement. Although CD10 negativity reflects an earlier stage of B-cell development, complete IgH gene rearrangements (VDJH), found in almost half of the patients, show more mature IgH status. Discordance between immunophenotype and genotype of infant ALL suggests an aberrant process in immunophenotypic steps of differentiation or a secondary down-regulation of CD10 expression. In this study, CD10-negative infant ALL with MLL/AF4, CD10-positive infant ALL with germline MLL, CD10-positive pre-B ALL cell line, infant acute myeloid leukemia (AML; M5) with MLL/AF9 and pediatric AML (M2) with AML1/ETO were analyzed for VDJH status and methylation of CD10 gene promoters. Three of the 4 infant ALL samples showed complete rearrangements of the VDJH gene with productive joints. Bisulfite sequencing of CD10 type 1 and 2 promoters showed that more than 84% of the cytosine-phosphate-guanine (CpG) dinucleotides identified were methylated in all 3 CD10-negative infant ALL samples with MLL/AF4. The CpG dinucleotides distributed in the clusters of putative Sp1-binding sites and functionally active regulatory regions of the promoters were fully methylated. In contrast, none of the CpG dinucleotides were methylated in the CD10-positive ALL samples. Structural evidence of dense methylation in the CD10 gene promoter suggested that methylated transcription factor binding sites contribute to CD10 silencing as an epigenetic mechanism. © 2010 by Lippincott Williams & Wilkins.","subitem_description_type":"Abstract"}]},"item_4_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学医薬保健研究域","subitem_description_type":"Other"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Lippincott, Williams & Wilkins"}]},"item_4_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1097/MPH.0b013e3181c29c3c","subitem_relation_type_select":"DOI"}}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AA11021846","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1077-4114","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Ikawa, Yasuhiro"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"Sugimoto, Naotoshi"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"Koizumi, Shoichi"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"Yachie, Akihiro"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"Saikawa, Yutaka"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-03"}],"displaytype":"detail","filename":"ME-PR-IKAWA-Y-4.pdf","filesize":[{"value":"736.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ME-PR-IKAWA-Y-4.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/14649/files/ME-PR-IKAWA-Y-4.pdf"},"version_id":"739cbc05-8b03-4ff9-a402-c949a1809459"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Dense methylation of types 1 and 2 regulatory regions of the CD10 gene promoter in infant acute lymphoblastic leukemia with MLL/AF4 fusion gene","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Dense methylation of types 1 and 2 regulatory regions of the CD10 gene promoter in infant acute lymphoblastic leukemia with MLL/AF4 fusion gene"}]},"item_type_id":"4","owner":"3","path":["1134"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-03"},"publish_date":"2017-10-03","publish_status":"0","recid":"14649","relation_version_is_last":true,"title":["Dense methylation of types 1 and 2 regulatory regions of the CD10 gene promoter in infant acute lymphoblastic leukemia with MLL/AF4 fusion gene"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-28T00:43:25.716190+00:00"}
