However, its tumor suppressor function remains largely uncharacterized. We herein generated mice missing Bcor exon 4, expressing a variant BCOR lacking the BCL6-binding domain. While the deletion of exon 4 in male mice (Bcor^ \u003c\u0394E4/y\u003e) compromised the repopulating capacity of hematopoietic stem cells, Bcor^\u003c\u0394E4/y\u003e thymocytes had augmented proliferative capacity in culture and showed a strong propensity to induce acute T-cell lymphoblastic leukemia (T-ALL) mostly in a Notch-dependent manner. Myc, one of the critical NOTCH1 targets in T-ALL, was highly upregulated in Bcor^\u003c\u0394E4/y\u003e T-ALL cells. ChIP-seq analysis revealed that BCOR was recruited to the Myc promoter and restrained its activation in thymocytes. BCOR also targeted other NOTCH1 targets and potentially antagonized their transcriptional activation. Bcl6-deficient thymocytes behaved in a similar manner to Bcor^\u003c\u0394E4/y\u003e thymocytes. Our results provide the first evidence of a tumor suppressor role for BCOR in the pathogenesis of T lymphocyte malignancies.", "subitem_description_type": "Abstract"}]}, "item_6_description_5": {"attribute_name": "\u5185\u5bb9\u8a18\u8ff0", "attribute_value_mlt": [{"subitem_description": "\u5b66\u4f4d\u306e\u7a2e\u985e: \u535a\u58eb\uff08\u533b\u5b66\uff09. \u5831\u544a\u756a\u53f7: \u7532\u7b2c4403\u53f7. \u5b66\u4f4d\u8a18\u756a\u53f7: \u65b0\u5927\u9662\u535a\uff08\u533b\uff09\u7532\u7b2c802\u53f7. \u5b66\u4f4d\u6388\u4e0e\u5e74\u6708\u65e5: \u5e73\u621030\u5e743\u670823\u65e5", "subitem_description_type": "Other"}, {"subitem_description": "Journal of Experimental Medicine. 2017.  214(10), 2901-2913.", "subitem_description_type": "Other"}]}, "item_6_description_53": {"attribute_name": "\u5b66\u4f4d\u8a18\u756a\u53f7", "attribute_value_mlt": [{"subitem_description": "\u65b0\u5927\u9662\u535a\uff08\u533b\uff09\u7532\u7b2c802\u53f7", "subitem_description_type": "Other"}]}, "item_6_dissertation_number_52": {"attribute_name": "\u5b66\u4f4d\u6388\u4e0e\u756a\u53f7", "attribute_value_mlt": [{"subitem_dissertationnumber": "13101\u7532\u7b2c4403\u53f7"}]}, "item_6_full_name_3": {"attribute_name": "\u8457\u8005\u5225\u540d", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "51229", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "\u7530\u4e2d, \u667a\u4e4b"}]}]}, "item_6_publisher_7": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "\u65b0\u6f5f\u5927\u5b66"}]}, "item_6_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "info:doi/10.1084/jem.20170167", "subitem_relation_type_select": "DOI"}}]}, "item_6_select_19": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "ETD"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Tanaka, Tomoyuki"}], "nameIdentifiers": [{"nameIdentifier": "51228", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-08-05"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "h29nmk802.pdf", "filesize": [{"value": "59.6 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 59600000.0, "url": {"label": "\u672c\u6587", "url": "https://niigata-u.repo.nii.ac.jp/record/6001/files/h29nmk802.pdf"}, "version_id": "4181e4c0-dbe2-4014-9e25-46abd1340820"}, {"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-08-05"}], "displaytype": "detail", "download_preview_message": "", "file_order": 1, "filename": "h29nmk802_a.pdf", "filesize": [{"value": "734.2 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 734200.0, "url": {"label": "\u8981\u65e8", "url": "https://niigata-u.repo.nii.ac.jp/record/6001/files/h29nmk802_a.pdf"}, "version_id": "2fec0b1b-20bc-465b-adaf-5b1e6c893ad9"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "thesis", "resourceuri": "http://purl.org/coar/resource_type/c_46ec"}]}, "item_title": "Internal deletion of BCOR reveals a tumor suppressor function for BCOR in T lymphocyte malignancies", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Internal deletion of BCOR reveals a tumor suppressor function for BCOR in T lymphocyte malignancies"}, {"subitem_title": "Internal deletion of BCOR reveals a tumor suppressor function for BCOR in T lymphocyte malignancies", "subitem_title_language": "en"}]}, "item_type_id": "6", "owner": "1", "path": ["453/455", "471/561/562"], "permalink_uri": "http://hdl.handle.net/10191/50416", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2018-07-26"}, "publish_date": "2018-07-26", "publish_status": "0", "recid": "6001", "relation": {}, "relation_version_is_last": true, "title": ["Internal deletion of BCOR reveals a tumor suppressor function for BCOR in T lymphocyte malignancies"], "weko_shared_id": 2}
