Tenascin C (TNC), an extracellular matrix glycoprotein, modulates tumor progression. We evaluated the functional roles of TNC, especially in PNI of PDAC.\nMethods: We examined immunohistochemical TNC expression in 78 resected PDAC specimens. The relationships between TNC expression and clinicopathological features were retrospectively analyzed. Interactions between cancer cells and TNC-supplemented nerves were investigated using an in vitro co-culture model with PDAC cell line and mouse dorsal root ganglion (DRG).\nResults: Tenascin C expression was predominant in perineural sites at invasive tumor front. High perineural TNC expression in 30 patients (38%) was associated with PNI, pathological T stage ? 3, and postoperative locoregional recurrence. High TNC expression was independently associated with postoperative, poor recurrence-free survival by multivariate analysis. In the in vitro co-culture model, a TNC-rich matrix enhanced both PDAC cell colony extensions toward nerves and DRG axonal outgrowth toward cancer cell colonies, whereas TNC did not affect axonal outgrowth or cancer cell proliferation in separately cultured DRG and PDAC cells.\nConclusions: Strong perineural TNC expression indicated poor prognosis with locoregional recurrence. The neurotropism of TNC-induced PDAC suggests TNC is a potential PDAC therapeutic target.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_5_dissertation_number_18":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第839号"}]},"item_5_publisher_6":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Wolters Kluwer Health","subitem_publisher_language":"en"}]},"item_5_relation_26":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"32132519","subitem_relation_type_select":"PMID"}}]},"item_5_relation_28":{"attribute_name":"出版社DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1097/MPA.0000000000001506","subitem_relation_type_select":"DOI"}}]},"item_5_source_id_19":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0885-3177","subitem_source_identifier_type":"EISSN"}]},"item_5_source_id_20":{"attribute_name":"EISSN","attribute_value_mlt":[{"subitem_source_identifier":"1536-4828","subitem_source_identifier_type":"PISSN"}]},"item_5_version_type_32":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"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":"古橋, 暁","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"10799","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":"2021-04-01"}],"displaytype":"detail","filename":"DT_839ronbun.pdf","filesize":[{"value":"5.6 MB"}],"format":"application/pdf","licensetype":"license_9","mimetype":"application/pdf","url":{"label":"論文本文","objectType":"fulltext","url":"https://hama-med.repo.nii.ac.jp/record/3654/files/DT_839ronbun.pdf"},"version_id":"07ec12d9-8503-4334-acd5-d2a1645cb29c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"pancreatic ductal adenocarcinoma","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"perineural invasion","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"tenascin C","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"dorsal root ganglion","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"tumor-nerve microenvironment","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"neurotropism","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":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"Tenascin C in the tumor-nerve microenvironment enhances perineural invasion and correlates with locoregional recurrence in pancreatic ductal adenocarcinoma","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Tenascin C in the tumor-nerve microenvironment enhances perineural invasion and correlates with locoregional recurrence in pancreatic ductal adenocarcinoma","subitem_title_language":"en"}]},"item_type_id":"5","owner":"4","path":["17"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2021-04-01"},"publish_date":"2021-04-01","publish_status":"0","recid":"3654","relation_version_is_last":true,"title":["Tenascin C in the tumor-nerve microenvironment enhances perineural invasion and correlates with locoregional recurrence in pancreatic ductal adenocarcinoma"],"weko_creator_id":"4","weko_shared_id":-1},"updated":"2023-10-13T06:54:18.077863+00:00"}
