We previously identified the overexpression of SIRT1 in ovarian carcinoma (OvCa) as a poor prognostic factor. However, mechanistic insights into the function of SIRT1 in OvCa have yet to be elucidated. METHODS: Quantitative real-time reverse PCR (qRTPCR) and Western blotting were employed to examine the expression of SIRT1 in a panel of human OvCa cell lines. si-RNA or sh-RNA and cDNA technologies were utilized to knockdown or overexpress SIRT1, respectively. The effects of SIRT1 on proliferation and chemoresistance were examined using a WST-1 assay, and the underlying mechanisms were confirmed using an apoptotic assay, and the quantification of glutathione (GSH), and reactive oxygen species (ROS). The aggressiveness of SIRT1 was analyzed using in vitro invasion and migration assays. RESULTS: SIRT1 was more strongly expressed in OvCa cell lines than in the immortalized ovarian epithelium at the gene and protein levels. Stress up-regulated the expression of SIRT1 in dose-and time-dependent manners. SIRT1 significantly enhanced the proliferation (P \u003c.05), chemoresistance (P \u003c.05), and aggressiveness of OvCa cells by up-regulating multiple antioxidant pathways to inhibit oxidative stress. Further study into the overexpression of SIRT1 demonstrated the up-regulation of several stemness-associated genes and enrichment of CD44v9 via an asyet- unidentified pathway. CONCLUSIONS: Our results suggest that SIRT1 plays a role in the acquisition of aggressiveness and chemoresistance by OvCa, and has potential as a therapeutic target for OvCa."}]}, "item_1627890986942": {"attribute_name": "出版タイプ", "attribute_value_mlt": [{"subitem_version_resource": "http://purl.org/coar/version/c_be7fb7dd8ff6fe43", "subitem_version_type": "NA"}]}, "item_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right": "open access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_abf2"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "MVUNTA, DAVID HAMISI", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "105901", "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": "2018-06-28"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "13MH081J_yoshi.pdf", "filesize": [{"value": "122.1 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 122100.0, "url": {"label": "内容の要旨", "url": "https://soar-ir.repo.nii.ac.jp/record/19948/files/13MH081J_yoshi.pdf"}, "version_id": "33fb1d72-fd10-4934-bd46-21c3a7090791"}, {"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2018-06-28"}], "displaytype": "detail", "download_preview_message": "", "file_order": 1, "filename": "13MH081J_shinsa.pdf", "filesize": [{"value": "111.3 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 111300.0, "url": {"label": "審査結果の要旨", "url": "https://soar-ir.repo.nii.ac.jp/record/19948/files/13MH081J_shinsa.pdf"}, "version_id": "7b48b59c-dbf4-4848-bae4-882afaf05591"}, {"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2018-06-28"}], "displaytype": "detail", "download_preview_message": "", "file_order": 2, "filename": "13MH081J_ronbun.pdf", "filesize": [{"value": "1.5 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensefree": "© 2017 The Authors.
