Herein, we examined the effect of HYA on gingival epithelial barrier function and its possible application for the prevention and treatment of periodontal disease. We found that GPR40, a fatty acid receptor, was expressed on gingival epithelial cells; activation of GPR40 by HYA significantly inhibited barrier impairment induced by Porphyromonas gingivalis, a representative periodontopathic bacterium. The degradation of E-cadherin and beta-catenin, basic components of the epithelial barrier, was prevented in a GPR40-dependent manner in vitro. Oral inoculation of HYA in a mouse experimental periodontitis model suppressed the bacteria-induced degradation of E-cadherin and subsequent inflammatory cytokine production in the gingival tissue. Collectively, these results suggest that HYA exerts a protective function, through GPR40 signaling, against periodontopathic bacteria-induced gingival epithelial barrier impairment and contributes to the suppression of inflammatory responses in periodontal diseases.","subitem_description_type":"Abstract"}]},"item_6_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"学位の種類: 博士（歯学）. 報告番号: 甲第4574号. 学位記番号: 新大院博（歯）甲第423号. 学位授与年月日: 平成31年3月25日","subitem_description_type":"Other"},{"subitem_description":"Scientific Reports. 2018, 8:9008","subitem_description_type":"Other"}]},"item_6_description_53":{"attribute_name":"学位記番号","attribute_value_mlt":[{"subitem_description":"新大院博（歯）甲第423号","subitem_description_type":"Other"}]},"item_6_dissertation_number_52":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"13101甲第4574号"}]},"item_6_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"175236","nameIdentifierScheme":"WEKO"}],"names":[{"name":"原, 実生"}]}]},"item_6_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"新潟大学"}]},"item_6_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1038/s41598-018-27408-y","subitem_relation_type_select":"DOI"}}]},"item_6_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"ETD"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Hara, Miki"}],"nameIdentifiers":[{"nameIdentifier":"175235","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-09-10"}],"displaytype":"detail","filename":"h30ndk423.pdf","filesize":[{"value":"3.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文","url":"https://niigata-u.repo.nii.ac.jp/record/32109/files/h30ndk423.pdf"},"version_id":"bcbe2a2c-2906-4ec7-b702-a7f61f4bd965"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-09-10"}],"displaytype":"detail","filename":"h30ndk423_a.pdf","filesize":[{"value":"255.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"要旨","url":"https://niigata-u.repo.nii.ac.jp/record/32109/files/h30ndk423_a.pdf"},"version_id":"782f9311-c617-4d99-9f2a-c603a06af84b"}]},"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":"thesis","resourceuri":"http://purl.org/coar/resource_type/c_46ec"}]},"item_title":"A bacterial metabolite ameliorates periodontal pathogen-induced gingival epithelial barrier disruption via GPR40 signaling","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A bacterial metabolite ameliorates periodontal pathogen-induced gingival epithelial barrier disruption via GPR40 signaling"},{"subitem_title":"A bacterial metabolite ameliorates periodontal pathogen-induced gingival epithelial barrier disruption via GPR40 signaling","subitem_title_language":"en"}]},"item_type_id":"6","owner":"1","path":["455","434"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-07-09"},"publish_date":"2019-07-09","publish_status":"0","recid":"32109","relation_version_is_last":true,"title":["A bacterial metabolite ameliorates periodontal pathogen-induced gingival epithelial barrier disruption via GPR40 signaling"],"weko_creator_id":"1","weko_shared_id":2},"updated":"2022-12-15T04:01:13.183188+00:00"}
