Increases in the aggregation and deposition of amyloid beta protein (Aβ) in the brain may be closely correlated with the development of Alzheimer's disease. In this study, the effects of an adzuki bean extract on the aggregation of Aβ were examined; moreover, the anti-Alzheimer's activity of the adzuki extract was examined. [MATERIALS/METHODS] First, we undertook thioflavin T (ThT) fluorescence analysis and transmission electron microscopy (TEM) to evaluate the effect of an adzuki bean extract on Aβ42 aggregation. To evaluate the effects of the adzuki extract on the symptoms of Alzheimer's disease in vivo, Aβ42-overexpressing Drosophila were used. In these flies, overexpression of Aβ42 induced the formation of Aβ42 aggregates in the brain, decreased motor function, and resulted in cognitive impairment. [RESULTS] Based on the results obtained by ThT fluorescence assays and TEM, the adzuki bean extract inhibited the formation of Aβ42 aggregates in a concentration-dependent manner. When Aβ42-overexpressing flies were fed regular medium containing adzuki extract, the Aβ42 level in the brain was significantly lower than that in the group fed regular medium only. Furthermore, suppression of the decrease in motor function, suppression of cognitive impairment, and improvement in lifespan were observed in Aβ42-overexpressing flies fed regular medium with adzuki extract. [CONCLUSIONS] The results reveal the delaying effects of an adzuki bean extract on the progression of Alzheimer's disease and provide useful information for identifying novel prevention treatments for Alzheimer's disease.","subitem_description_type":"Abstract"}]},"item_2_publisher_36":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"the Korean Nutrition Society and the Korean Society of Community"}]},"item_2_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.4162/nrp.2019.13.1.64","subitem_relation_type_select":"DOI"}}]},"item_2_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2019 The Korean Nutrition Society and the Korean Society of Community Nutrition"}]},"item_2_rights_16":{"attribute_name":"権利（URI）","attribute_value_mlt":[{"subitem_rights":"http://creativecommons.org/licenses/by-nc/3.0/ | http://creativecommons.org/licenses/by-nc/3.0/"}]},"item_2_version_type_19":{"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":"Miyazaki, Honami"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Okamoto, Yoko"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Motoi, Aya"}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":""}],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"Watanabe, Takafumi","creatorNameLang":"en"},{"creatorName":"渡邉, 敬文","creatorNameLang":"ja"}],"familyNames":[{},{}],"givenNames":[{},{}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"Katayama, Shigeru"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kawahara, Sei-ichi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Makabe, Hidefumi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Fujii, Hiroshi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yonekura, Shinichi"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-11-18"}],"displaytype":"detail","filename":"R-2020-58_watanabe.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"R-2020-58_watanabe.pdf","url":"https://rakuno.repo.nii.ac.jp/record/6400/files/R-2020-58_watanabe.pdf"},"version_id":"59efeb8e-33e6-45cf-924d-5a1e86312e46"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Adzuki bean","subitem_subject_scheme":"Other"},{"subitem_subject":"alzheimer disease","subitem_subject_scheme":"Other"},{"subitem_subject":"amyloid beta","subitem_subject_scheme":"Other"},{"subitem_subject":"drosophila","subitem_subject_scheme":"Other"},{"subitem_subject":"Adzuki bean","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"alzheimer disease","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"amyloid beta","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"drosophila","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Adzuki bean (Vigna angularis) extract reduces amyloid-β aggregation and delays cognitive impairment in Drosophila models of Alzheimer's disease","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Adzuki bean (Vigna angularis) extract reduces amyloid-β aggregation and delays cognitive impairment in Drosophila models of Alzheimer's disease"}]},"item_type_id":"2","owner":"3","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-11-18"},"publish_date":"2020-11-18","publish_status":"0","recid":"6400","relation_version_is_last":true,"title":["Adzuki bean (Vigna angularis) extract reduces amyloid-β aggregation and delays cognitive impairment in Drosophila models of Alzheimer's disease"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-08-31T02:06:19.162115+00:00"}
