A dysfunctional epithelial barrier is closely associated with the pathogenesis of a variety of intestinal and systemic disorders. We investigated here the effects of nitric oxide (NO) and hydrogen peroxide (H2O2) on the barrier function of a human intestinal epithelial cell line, Caco-2. When treated with H2O2, Caco-2 cell monolayers grown on permeable supports exhibited several remarkable features of barrier dysfunction as follows: a decrease in transepithelial electrical resistance, an increase in paracellular permeability to dextran, and a disruption of the intercellular junctional localization of the scaffolding protein ZO-1. In addition, an induction of tyrosine phosphorylation of numerous cellular proteins including ZO-1, E-cadherin, and ß-catenin, components of tight and adherens junctions, was observed. On the other hand, combined treatment of Caco-2 monolayers with H2O2 and an NO donor (NOC5 or NOC12) relieved the damage to the barrier function and suppressed the protein tyrosine phosphorylation induced by H2O2 alone. These results suggest that NO protects the barrier function of intestinal epithelia from oxidative stress by modulating some intracellular signalling pathways of protein tyrosine phosphorylation in epithelial cells.","subitem_description_type":"Abstract"}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0167-4889","subitem_source_identifier_type":"ISSN"}]},"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":"Katsube, Takanori"}],"nameIdentifiers":[{"nameIdentifier":"445756","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tsuji, Hideo"}],"nameIdentifiers":[{"nameIdentifier":"445757","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Onoda, Makoto"}],"nameIdentifiers":[{"nameIdentifier":"445758","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"勝部 孝則","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"445759","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"辻 秀雄","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"445760","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小野田 眞","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"445761","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Nitric oxide attenuates hydrogen peroxide-induced barrier disruption and protein tyrosine phosphorylation in monolayers of intestinal epithelial cell.","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Nitric oxide attenuates hydrogen peroxide-induced barrier disruption and protein tyrosine phosphorylation in monolayers of intestinal epithelial cell."}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-06-15"},"publish_date":"2007-06-15","publish_status":"0","recid":"44881","relation_version_is_last":true,"title":["Nitric oxide attenuates hydrogen peroxide-induced barrier disruption and protein tyrosine phosphorylation in monolayers of intestinal epithelial cell."],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T00:10:14.896187+00:00"}
