Cells subject to such environmental change express stress proteins, which contribute importantly to maintenance of metabolic homeostasis and viability. We show that an inducible chaperone present in endoplasmic reticulum (ER), the 150-kDa oxygen-regulated protein (ORP150), is expressed both in the human brain after seizure attack and in mouse hippocampus after kainate administration. Using mice heterozygous for ORP150 deficiency, exposure to excitatory stimuli caused hippocampal neurons to display exaggerated elevation of cytosolic calcium accompanied by activation of μ-calpain and cathepsin B, as well as increased vulnerability to glutamate-induced cell death in vitro and decreased survival to kainate in vivo. In contrast, targeted neuronal overexpression of ORP150 suppressed each of these events and enhanced neuronal and animal survival in parallel with diminished seizure intensity. Studies using cultured hippocampal neurons showed that ORP150 regulates cytosolic free calcium and activation of proteolytic pathways causing cell death in neurons subject to excitatory stress. Our data underscore a possible role for ER stress in glutamate toxicity and pinpoint a key ER chaperone, ORP150, which contributes to the stress response critical for neuronal survival.","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医学系","subitem_description_type":"Other"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Society for Clinical Investigation"}]},"item_4_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1172/JCI200112978","subitem_relation_type_select":"DOI"}}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AA00695520","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0021-9738","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_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kitao, Yasuko"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"Ozawa, Kentaro"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"Miyazaki, Mayuki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tamatani, Michio"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kobayashi, Tomohiro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yanagi, Hideki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Okabe, Masaru"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ikawa, Masahito"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamashima, Tetsumori"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"Stern, David M."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hori, Osamu"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"Ogawa, Satoshi"}],"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-KITAO-Y-1439.pdf","filesize":[{"value":"7.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ME-PR-KITAO-Y-1439.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/13257/files/ME-PR-KITAO-Y-1439.pdf"},"version_id":"6dc85b6d-9d4f-4838-b85a-fcb18ea5e84d"}]},"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":"Expression of the endoplasmic reticulum molecular chaperone (ORP150) rescues hippocampal neurons from glutamate toxicity","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Expression of the endoplasmic reticulum molecular chaperone (ORP150) rescues hippocampal neurons from glutamate toxicity"}]},"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":"13257","relation_version_is_last":true,"title":["Expression of the endoplasmic reticulum molecular chaperone (ORP150) rescues hippocampal neurons from glutamate toxicity"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-28T01:08:27.639362+00:00"}
