The aim of the present study is to inves tigate whether other small molecules that are known to be involved in modulating key signaling pathways may act like NAM in affecting the senescent phenotypes. Specifically, we found the activators for sirtuin, AMP kinase and autophagy signaling all suppress the senescent phenotypes, whereas their inhibitors induce senescent phenotypes. On the other hand, the inhibitors of phosphoi nositide 3 kinase (PI3K) suppressed senescent phenotypes. To further analyze the role of NAM and PI3K in the senescence modulati ng process, we examined the expression of various PI3K catalytic units and the phosphorylation of Akt, a PI3K downstream target. Our study suggested that the expression of senescent phenotypes in human diploid cells is intimately connected to signaling ne tworks involved in energy metabolism and autophagy.","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"千葉科学大学"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2436-2565","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"松岡, 耕二"},{"creatorName":"マツオカ, コウジ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"712","nameIdentifierScheme":"WEKO"},{"nameIdentifier":" 9000291613762","nameIdentifierScheme":"CiNii ID","nameIdentifierURI":"http://ci.nii.ac.jp/nrid/ 9000291613762"}]},{"creatorNames":[{"creatorName":"佐々木, 啓子"}],"nameIdentifiers":[{"nameIdentifier":"456","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"CHEN, Kuang Yu"}],"nameIdentifiers":[{"nameIdentifier":"1042","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"MATUOKA, Koozi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"454","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"SASAKI, Keiko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"460","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"CHEN, Kuang Yu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1043","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":"2021-04-05"}],"displaytype":"detail","filename":"6-14松岡耕二.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","license_note":"copyright (c) 2020 by chiba Institute of Science","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"6-14松岡耕二","url":"https://cis.repo.nii.ac.jp/record/338/files/6-14松岡耕二.pdf"},"version_id":"afffd1a9-e047-4aeb-a9ce-65b235ed679f"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Suppression of Senescent Phenotypes in Normal Human Diploid Cells by Nicotinamide and phosphoinositide 3-kinase inhibitors","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Suppression of Senescent Phenotypes in Normal Human Diploid Cells by Nicotinamide and phosphoinositide 3-kinase inhibitors"},{"subitem_title":"Suppression of Senescent Phenotypes in Normal Human Diploid Cells by Nicotinamide and phosphoinositide 3-kinase inhibitors","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"15","path":["31"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-04-05"},"publish_date":"2021-04-05","publish_status":"0","recid":"338","relation_version_is_last":true,"title":["Suppression of Senescent Phenotypes in Normal Human Diploid Cells by Nicotinamide and phosphoinositide 3-kinase inhibitors"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2023-06-19T07:51:50.139875+00:00"}
