The p53 gene-product was overexpressed in 83 (63%) of the 131, and mutations were detected in 24 (35%) of the 69 tumors examined. The mutations were predominantly located at exons 5 (58%) and 7 (27%), and detected in 13 (31%) of 42 overexpressing tumors, in none of 4 sporadic tumors and in 8 (40%) of 20 negative tumors. The p53 alteration did not correlate with the clinicopathological factors, including pTNM categories, stage, depth of invasion, and size of intramucosal carcinomas. These results indicate that p53 protein overexpression and gene mutation may occur during an early stage of esophageal carcinogenesis and have no impact on clinicopathological factors. The higher frequency of p53 overexpression compared to mutation suggests that p53 accumulation can occur by other mechanisms besides p53 mutation.","subitem_description_type":"Abstract"}]},"item_7_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Niigata University School of Medicine"}]},"item_7_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_7_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00508361","subitem_source_identifier_type":"NCID"}]},"item_7_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"05677734","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Nakagawa, Satoru"}],"nameIdentifiers":[{"nameIdentifier":"52905","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Watanabe, Hidenobu"}],"nameIdentifiers":[{"nameIdentifier":"52906","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ajioka, Yoichi"}],"nameIdentifiers":[{"nameIdentifier":"52907","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nishikura, Ken"}],"nameIdentifiers":[{"nameIdentifier":"52908","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hitomi, Jiro"}],"nameIdentifiers":[{"nameIdentifier":"52909","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hatakeyama, Katsuyoshi"}],"nameIdentifiers":[{"nameIdentifier":"52910","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":"2019-08-06"}],"displaytype":"detail","filename":"44(2)_63-69.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"44(2)_63-69.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/6434/files/44(2)_63-69.pdf"},"version_id":"0fd30a4c-7ed8-49b0-ae9b-b15031d8f2d1"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"p53 overexpression","subitem_subject_scheme":"Other"},{"subitem_subject":"p53 gene mutation","subitem_subject_scheme":"Other"},{"subitem_subject":"esophageal carcinoma","subitem_subject_scheme":"Other"},{"subitem_subject":"clinicopathological factors","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Archival Analysis of p53 Protein Overexpression and Genetic Mutation in Esophageal Squamous Cell Carcinoma","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Archival Analysis of p53 Protein Overexpression and Genetic Mutation in Esophageal Squamous Cell Carcinoma"},{"subitem_title":"Archival Analysis of p53 Protein Overexpression and Genetic Mutation in Esophageal Squamous Cell Carcinoma","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["456","619"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-08-27"},"publish_date":"2015-08-27","publish_status":"0","recid":"6434","relation_version_is_last":true,"title":["Archival Analysis of p53 Protein Overexpression and Genetic Mutation in Esophageal Squamous Cell Carcinoma"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:39:42.909501+00:00"}
