In the present study, we examined the effect of indomethacin, a non-selective inhibitor of cyclooxygenase (COX), on the expression of TFF mRNA expression in MKN 45 gastric cells by real-time quantitative RT-PCR method. In MKN 45 cells, relative expression level of TFF1, TFF2, and TFF3 mRNA was 617 : 12 : 1 in the control condition. Indomethacin up-regulated the expression level of TFF 2 in a dose-dependent manner, whereas TFF 1 and TFF 3 expression levels were not significantly affected. Luciferase reporter gene assay confirmed this stimulatory effect of indomethacin on TFF 2 expression. Other COX inhibitors, such as aspirin and NS -398, also up-regulated TFF 2 expression and indomethacin-induced up-regulation of TFF2 expression was also observed in other gatric cell lines, such as AGS and JR. Externally applied PGE2 did not antagonize the effect of indomethacin on TFF2 expression. Since TFF peptides play a critical role in gastric mucosal protection, indomethacin-induced TFF2 may reduce the degree of gastric mucosal damage induced by indomethacin. The present results also suggest that the effect of indomethacin on TFF2 expression is COX-independent.", "subitem_description_type": "Other"}]}, "item_2_description_15": {"attribute_name": "表示順", "attribute_value_mlt": [{"subitem_description": "14", "subitem_description_type": "Other"}]}, "item_2_description_16": {"attribute_name": "アクセション番号", "attribute_value_mlt": [{"subitem_description": "KJ00000010453", "subitem_description_type": "Other"}]}, "item_2_description_8": {"attribute_name": "記事種別(日)", "attribute_value_mlt": [{"subitem_description": "原著", "subitem_description_type": "Other"}]}, "item_2_description_9": {"attribute_name": "記事種別(英)", "attribute_value_mlt": [{"subitem_description": "Original", "subitem_description_type": "Other"}]}, "item_2_source_id_1": {"attribute_name": "雑誌書誌ID", "attribute_value_mlt": [{"subitem_source_identifier": "AA00629581", "subitem_source_identifier_type": "NCID"}]}, "item_2_source_id_19": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "03855023", "subitem_source_identifier_type": "ISSN"}]}, "item_2_text_6": {"attribute_name": "著者所属(日)", "attribute_value_mlt": [{"subitem_text_value": "獨協医科大学内科学(消化器)"}, {"subitem_text_value": "獨協医科大学内科学(消化器)"}]}, "item_2_text_7": {"attribute_name": "著者所属(英)", "attribute_value_mlt": [{"subitem_text_language": "en", "subitem_text_value": "Department of Gastroenterology, Dokkyo University School of Medicine"}, {"subitem_text_language": "en", "subitem_text_value": "Department of Gastroenterology, Dokkyo University School of Medicine"}]}, "item_2_title_3": {"attribute_name": "論文名よみ", "attribute_value_mlt": [{"subitem_title": "イネンマク ジョウヒ サイボウ ノ trefoil factor family ハツゲン ニ オヨボス indomethacin ノ エイキョウ"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "小板橋, 綾子"}, {"creatorName": "コイタバシ, アヤコ", "creatorNameLang": "ja-Kana"}], "nameIdentifiers": [{"nameIdentifier": "363", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "島田, 忠人"}, {"creatorName": "シマダ, タダヒト", "creatorNameLang": "ja-Kana"}], "nameIdentifiers": [{"nameIdentifier": "364", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Koitabashi, Ayako", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "365", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Shimada, Tadahito", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "366", "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": "2017-05-24"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "KJ00000010453.pdf", "filesize": [{"value": "850.1 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 850100.0, "url": {"label": "KJ00000010453.pdf", "url": "https://dmu.repo.nii.ac.jp/record/122/files/KJ00000010453.pdf"}, "version_id": "f6f13b28-dd17-4e4b-bc1c-05f813fd857c"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "非ステロイド性抗炎症薬 (NSAIDs)", "subitem_subject_scheme": "Other"}, {"subitem_subject": "trefoil factor family", "subitem_subject_scheme": "Other"}, {"subitem_subject": "胃粘膜傷害", "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": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "胃粘膜上皮細胞のtrefoil factor family発現に及ぼすindomethacinの影響", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "胃粘膜上皮細胞のtrefoil factor family発現に及ぼすindomethacinの影響"}, {"subitem_title": "Effect of Indomethacin on TFF Expression in Gastric Epithelial Cells", "subitem_title_language": "en"}]}, "item_type_id": "2", "owner": "3", "path": ["25"], "permalink_uri": "https://dmu.repo.nii.ac.jp/records/122", "pubdate": {"attribute_name": "公開日", "attribute_value": "2017-05-24"}, "publish_date": "2017-05-24", "publish_status": "0", "recid": "122", "relation": {}, "relation_version_is_last": true, "title": ["胃粘膜上皮細胞のtrefoil factor family発現に及ぼすindomethacinの影響"], "weko_shared_id": 3}
