In general, the sex difference in incidence of human bladder carcinoma is considered to be due to industrial and environmental carcinogens or other factors, though there is no clear evidence supporting this. We suspected that the sex difference in incidence of bladder carcinoma might be due to the effects of testosterone. We investigated the effects of testosterone on mouse bladder arcinogenesis by using immunohistochemical staining and terminal-deoxynucleotidyl-transferase (TdT)-mediated dUTP-biotin nick end labeling (TUNEL). A total of 94 four-week-old male mice were divided into 3 groups. In Group I, castration was carried out, then 0.05% N-butyl-N-(4-hydroxybutyl)nitrosamine (BBN) was administered until the end of the experiment. In Group II, 0.05% BBN was administered similarly, without castration. In Group III, 0.05% BBN was administered similarly, without castration, and 3 mg/kg of testosterone was injected intramuscularly weekly from the beginning of the experiment. All mice were cystectomized at the end of the experimental period to investigate the incidence of bladder cancer, and immunohistochemical staining and TUNEL were performed to examine the correlation between cell proliferation and apoptosis. Among the 3 groups, occurrence of bladder tumor was most frequent in Group III, and tumor induction time was the shortest. The proliferation index for tumors significantly increased as the stage and grade progressed. On the other hand, the apoptotic index for tumors significantly decreased. The proliferation index was the highest in Group III and the lowest in Group I. A significant difference in the proliferation index was observed among the 3 groups. No significant difference was observed in the apoptotic index among the 3 groups. Our results indicate that the effect of testosterone on mouse bladder carcinogenesis is more significantly related to cell proliferation than to suppression of apoptosis, with the result that testosterone promotes the occurrence of BBN-induced mouse bladder carcinomas.", "subitem_description_type": "Other"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Tottori University Faculty of Medicine"}]}, "item_10001_relation_16": {"attribute_name": "情報源", "attribute_value_mlt": [{"subitem_relation_name": [{"subitem_relation_name_text": "Yonago Acta medica. 2000, 43(3), 121-130"}]}]}, "item_10001_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "Yonago Acta medica　編集委員会"}]}, "item_10001_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AA00892882", "subitem_source_identifier_type": "NCID"}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "13468049", "subitem_source_identifier_type": "ISSN"}]}, "item_10001_text_25": {"attribute_name": "EARMAS ID", "attribute_value_mlt": [{"subitem_text_value": "881"}]}, "item_10001_text_29": {"attribute_name": "最新掲載誌名", "attribute_value_mlt": [{"subitem_text_value": "yam;Yonago Acta medica;Yonago Acta medica"}]}, "item_10001_text_32": {"attribute_name": "著者所属", "attribute_value_mlt": [{"subitem_text_value": "Department of Urology, Faculty of Medicine, Tottori University"}]}, "item_10001_version_type_20": {"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": "Ohno, Hirofumi"}], "nameIdentifiers": [{"nameIdentifier": "19186", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ohno, Hirofumi", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "19187", "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": "2009-06-08"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "43_121-130.pdf", "filesize": [{"value": "315.1 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensefree": "Yonago Acta medica　編集委員会", "licensetype": "license_note", "mimetype": "application/pdf", "size": 315100.0, "url": {"label": "43_121-130.pdf", "url": "https://repository.lib.tottori-u.ac.jp/record/5164/files/43_121-130.pdf"}, "version_id": "8c85b84a-3f5c-4030-8693-640958df5fb5"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "apoptosis", "subitem_subject_scheme": "Other"}, {"subitem_subject": "BBN-induced mouse urinary bladder carcinogenesis", "subitem_subject_scheme": "Other"}, {"subitem_subject": "cell proliferation", "subitem_subject_scheme": "Other"}, {"subitem_subject": "testosterone", "subitem_subject_scheme": "Other"}, {"subitem_subject": "apoptosis", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "BBN-induced mouse urinary bladder carcinogenesis", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "cell proliferation", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "testosterone", "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": "Effects of Testosterone on Cell Proliferation and Apoptosis in BBN-Induced Mouse Urinary Bladder Carcinogenesis", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Effects of Testosterone on Cell Proliferation and Apoptosis in BBN-Induced Mouse Urinary Bladder Carcinogenesis", "subitem_title_language": "en"}]}, "item_type_id": "10001", "owner": "10", "path": ["12", "9", "1090"], "permalink_uri": "https://repository.lib.tottori-u.ac.jp/records/5164", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2018-06-22"}, "publish_date": "2018-06-22", "publish_status": "0", "recid": "5164", "relation": {}, "relation_version_is_last": true, "title": ["Effects of Testosterone on Cell Proliferation and Apoptosis in BBN-Induced Mouse Urinary Bladder Carcinogenesis"], "weko_shared_id": -1}
