Recently, we have reported that the antiproliferative effect of naftopidil is not related to androgen sensitivity of the cells or the ?1-adrenoceptor subtype expression in prostate cancer cells, suggesting that naftopidil has an off-target effect for various types of cells. To identify the cellular signal targets of naftopidil in CAFs, we used the SCADS inhibitor kits including more than 320 chemicals. Our results demonstrated that inhibitors against GSK-3 and CDK showed the similar effects with naftopidil in PCaSC-8. In addition, western blot analysis showed that the decreases of GSK-3 phosphorylation and CDK2 abundance were observed in naftopidil-treated cells. Finally, we suggest that GSK-3 and CDK2 might be important targets for induction of G1 cell cycle arrest by naftopidil treatment.", "subitem_description_type": "Abstract"}]}, "item_8_description_5": {"attribute_name": "内容記述", "attribute_value_mlt": [{"subitem_description": "2011度～2012年度科学研究費補助金(若手研究(B))研究成果報告書", "subitem_description_type": "Other"}]}, "item_8_description_64": {"attribute_name": "科研費番号", "attribute_value_mlt": [{"subitem_description": "23791751", "subitem_description_type": "Other"}]}, "item_8_publisher_30": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "三重大学"}]}, "item_8_text_18": {"attribute_name": "その他のタイトル", "attribute_value_mlt": [{"subitem_text_value": "A new therapeutic strategy for castration-resistant prostate cancer by off-target effects of naftopidil"}]}, "item_8_text_65": {"attribute_name": "資源タイプ（三重大）", "attribute_value_mlt": [{"subitem_text_value": "Kaken / 科研費報告書"}]}, "item_8_version_type_15": {"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": "石井, 健一朗", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "19596", "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": "2017-02-18"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "30K17229.pdf", "filesize": [{"value": "418.1 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 418100.0, "url": {"label": "30K17229.pdf", "url": "https://mie-u.repo.nii.ac.jp/record/8032/files/30K17229.pdf"}, "version_id": "ab7ca830-e4c8-4b2b-8f55-031566da7db7"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "前立腺癌", "subitem_subject_scheme": "Other"}, {"subitem_subject": "癌関連線維芽細胞", "subitem_subject_scheme": "Other"}, {"subitem_subject": "ナフトピジル", "subitem_subject_scheme": "Other"}, {"subitem_subject": "オフターゲット効果", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "research report", "resourceuri": "http://purl.org/coar/resource_type/c_18ws"}]}, "item_title": "前立腺肥大症治療薬のオフターゲット効果による再燃前立腺癌の新規治療戦略", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "前立腺肥大症治療薬のオフターゲット効果による再燃前立腺癌の新規治療戦略", "subitem_title_language": "ja"}]}, "item_type_id": "8", "owner": "15", "path": ["1692670337748"], "permalink_uri": "http://hdl.handle.net/10076/14267", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2014-12-18"}, "publish_date": "2014-12-18", "publish_status": "0", "recid": "8032", "relation": {}, "relation_version_is_last": true, "title": ["前立腺肥大症治療薬のオフターゲット効果による再燃前立腺癌の新規治療戦略"], "weko_shared_id": -1}
