The expression of nitric oxide synthase (NOS) isoform was also examined by quantitative reverse transcriptase-mediated polymerase chain reaction (RT-PCR). In the whole uterus, NO production was first detected by EPR spectroscopy on day 13.5 of gestation, and the NO level reached a peak on day 17.5 of gestation, and then significantly decreased through the last few days of gestation, resulting the same level of non-pregnant rats. The NO production in the whole uterus is mostly derived from the dicidua through the gestation. In the decidua, the expression of NOS II mRNA as measured by quantitative RT-PCR was stronger than that of NOS III mRNA, and the NOS II mRNA expression pattern was in good agreement with the NO production pattern, whereas NOS III mRNA expression showed no marked changes during gestation except a temporal increase at the term. In addition, NOS isoform expression at the peak of NO production stages (day 17.5) was examined after treatment with RU486, an anti-progesterone reagent, or raloxifene, an anti-estrogen reagent. The expression of the NOS II in the decidua at this stages was significantly decreased by these anti-steroid hormone treatments alone, but not affected by co-treatment of anti-progesterone and anti-estrogen treatment. NOS III expression was not affected by these anti-steroid hormone treatments. The present results indicate that uterine NO production was gestational stage-dependent, and the peak of NO production on day 17.5 was derived from the decidua and decidual NO production were mainly regulated by the expression of NOS II. The expression of NOS II was modified by steroid hormones, suggesting that steroid hormones up-regulate the iNOS expression in the decidua through the gestation to maintained the whole uterine NO production.","subitem_description_type":"Other"}]},"item_12_description_2":{"attribute_name":"ページ属性","attribute_value_mlt":[{"subitem_description":"P(論文)","subitem_description_type":"Other"}]},"item_12_description_3":{"attribute_name":"記事種別","attribute_value_mlt":[{"subitem_description":"特集","subitem_description_type":"Other"}]},"item_12_description_34":{"attribute_name":"format","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_12_description_4":{"attribute_name":"Type","attribute_value_mlt":[{"subitem_description":"FEATURE ARTICLES","subitem_description_type":"Other"}]},"item_12_publisher_19":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"麻布大学"}]},"item_12_publisher_20":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"Azabu University"}]},"item_12_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1346-5880","subitem_source_identifier_type":"ISSN"}]},"item_12_source_id_23":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11561468","subitem_source_identifier_type":"NCID"}]},"item_12_text_11":{"attribute_name":"所属機関","attribute_value_mlt":[{"subitem_text_value":"麻布大学大学院獣医学研究科"},{"subitem_text_value":"麻布大学大学院獣医学研究科"},{"subitem_text_value":"麻布大学大学院獣医学研究科"}]},"item_12_text_12":{"attribute_name":"Institution or Company","attribute_value_mlt":[{"subitem_text_value":"Graduate School of Veterinary Medicine, Azabu University"},{"subitem_text_value":"Graduate School of Veterinary Medicine, Azabu University"},{"subitem_text_value":"Graduate School of Veterinary Medicine, Azabu University"}]},"item_12_version_type_29":{"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_12_version_type_30":{"attribute_name":"text version","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":"滝沢, 達也"},{"creatorName":"タキザワ, タツヤ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"神作, 宜男"},{"creatorName":"カンサク, ノリオ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"田中, 和明"},{"creatorName":"タナカ, カズアキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TAKIZAWA, Tatsuya","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KANSAKU, Norio","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TANAKA, Kazuaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2005-01-01"}],"displaytype":"detail","filename":"bull_jau_vol11-12-208.pdf","filesize":[{"value":"289.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"bull_jau_vol11-12-208.pdf","url":"https://az.repo.nii.ac.jp/record/4861/files/bull_jau_vol11-12-208.pdf"},"version_id":"0aab9749-670e-47cb-853e-89de890a2c15"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"胎盤と子宮におけるNO産生の意義とNOS遺伝子発現調節機構","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"胎盤と子宮におけるNO産生の意義とNOS遺伝子発現調節機構"},{"subitem_title":"Expression of nitric oxide synthase isoforms and detection of nitric oxide in rat placenta and uterus during pregnancy","subitem_title_language":"en"}]},"item_type_id":"12","owner":"4","path":["508"],"pubdate":{"attribute_name":"公開日","attribute_value":"2005-01-01"},"publish_date":"2005-01-01","publish_status":"0","recid":"4861","relation_version_is_last":true,"title":["胎盤と子宮におけるNO産生の意義とNOS遺伝子発現調節機構"],"weko_creator_id":"4","weko_shared_id":-1},"updated":"2023-06-19T08:00:26.714687+00:00"}
