O-GlcNAcylation, mediated by O-GlcNAc transferase (OGT), involves the addition of N-acetylglucosamine to proteins and serves as an intracellular nutrient sensing mechanism. However, the role of O-GlcNAcylation in endothelial cells remains poorly understood.\nObjective\nThis study investigated the role of O-GlcNAcylation in endothelial cells.\nMethods\nEndothelial-cell-specific Ogt -knockout mice (Ogt-ECKO) were generated by crossing Ogt-floxed mice (Ogt-flox) with VE-Cadherin Cre ERT2 mice. Ogt-ECKO mice and Ogt-flox control mice were subjected to a normal or high-fat diet, and their body weight, glucose metabolism, and lipid metabolism were examined.\nResults\nOgt-ECKO mice exhibited reduced body weight compared with Ogt-flox control mice under a high-fat diet. Lipid absorption was significantly impaired in Ogt-ECKO mice. Changes in the intercellular junctions of small intestinal lacteal endothelial cells from a button-like to a zipper-like configuration were observed. Furthermore, Ogt-ECKO mice showed decreased expression of VEGFR3. The administration of a nitric oxide donor restored lipid absorption and reversed the morphological alterations in Ogt-ECKO mice.\nConclusions\nThese findings demonstrate the critical role of O-GlcNAcylation in endothelial cells in lipid absorption in the intestine through the modulation of lacteal junction morphology. These results provide novel insight into the metabolic regulatory mechanisms under physiological conditions and have implications for the development of new therapeutic strategies for obesity.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_6_description_69":{"attribute_name":"学位授与年度","attribute_value_mlt":[{"subitem_description":"令和6年度","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_6_dissertation_number_71":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第1020号"}]},"item_6_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier","subitem_publisher_language":"en"}]},"item_6_relation_10":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"39130439","subitem_relation_type_select":"PMID"}}]},"item_6_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/j.heliyon.2024.e34490","subitem_relation_type_select":"DOI"}}]},"item_6_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2405-8440","subitem_source_identifier_type":"ISSN"}]},"item_6_version_type_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43","subitem_version_type":"NA"}]},"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":"Ohgaku, Seiichiro","creatorNameLang":"en","creatorNameType":"Personal"}],"nameIdentifiers":[{"nameIdentifier":"9602","nameIdentifierScheme":"WEKO"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Obesity","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Endothelial cell","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"O-GlcNAcylation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Lipid absorption","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Vascular endothelial growth factor receptor 3","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Nitric oxide","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"O-GlcNAc modification in endothelial cells modulates adiposity via fat absorption from the intestine in mice","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"O-GlcNAc modification in endothelial cells modulates adiposity via fat absorption from the intestine in mice","subitem_title_language":"en"}]},"item_type_id":"6","owner":"11","path":["37"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2025-06-17"},"publish_date":"2025-06-17","publish_status":"0","recid":"2000473","relation_version_is_last":true,"title":["O-GlcNAc modification in endothelial cells modulates adiposity via fat absorption from the intestine in mice"],"weko_creator_id":"11","weko_shared_id":-1},"updated":"2025-07-14T02:25:10.375338+00:00"}
