The aim of the present study was to elucidate the role of the mTOR pathway in HPV-related oropharyngeal squamous cell carcinoma (OPSCC).\nMethods: The present study involved two strategies. The first was to investigate the activity of mTOR and mTOR-related complexes in high-risk HPV-positive (UM-SCC47 and CaSki) and HPV-negative (SCC-4 and SAS) cancer cell lines. The second was to elucidate mTOR complex expression in 80 oropharyngeal cancer tissues and to examine the relationship between mTOR complex expression and survival in patients with OPSCC.\nResults: The UM-SCC47 and CaSki cell lines showed high gene and protein expression of raptor. They also exhibited G1/S and G2/M phase cell cycle arrest following 24 h incubation with 6 μM temsirolimus, a rapamycin analog, and temsirolimus administration inhibited their growth. HPV-related OPSCC samples showed high gene and protein expression of raptor and rictor compared with HPV-unrelated OPSCC. In addition, HPV-related OPSCC patients with high raptor and rictor expression tended to have a worse prognosis than those with low or medium expression.\nConclusions: These results suggest that raptor and rictor have important roles in HPV-related OPSCC and that temsirolimus is a potential therapeutic agent for patients with HPV-related OPSCC. This is the first report to reveal the overexpression of raptor and rictor in HPV-related OPSCC.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学"},{"subitem_1522300295150":"en","subitem_1522300316516":"University of the Ryukyus"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"eng"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"EISSN","subitem_1522646572813":"1471-2407"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"en","subitem_1522650091861":"BMC Cancer"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicVolumeNumber":"21"}]},"item_1617187087799":{"attribute_name":"Dissertation Number","attribute_value_mlt":[{"subitem_1551256171004":"甲第532号"}]},"item_1617187112279":{"attribute_name":"Degree Name","attribute_value_mlt":[{"subitem_1551256126428":"博士(医学)","subitem_1551256129013":"ja"}]},"item_1617187136212":{"attribute_name":"Date Granted","attribute_value_mlt":[{"subitem_1551256096004":"2021-09-30"}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_1522305645492":"VoR","subitem_1600292170262":"http://purl.org/coar/version/c_970fb48d4fbd8a85"}]},"item_1617353299429":{"attribute_name":"Relation","attribute_value_mlt":[{"subitem_1522306287251":{"subitem_1522306382014":"DOI","subitem_1522306436033":"https://doi.org/10.1186/s12885-021-07794-9"}}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2022-06-09"}],"filename":"iken532abstract.pdf","filesize":[{"value":"794 KB"}],"url":{"objectType":"abstract","url":"https://u-ryukyu.repo.nii.ac.jp/record/2018025/files/iken532abstract.pdf"},"version_id":"f6a2ebfb-e250-4f58-8f59-f147c4432584"},{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2022-06-09"}],"filename":"iken532review.pdf","filesize":[{"value":"2.1 MB"}],"url":{"objectType":"other","url":"https://u-ryukyu.repo.nii.ac.jp/record/2018025/files/iken532review.pdf"},"version_id":"12c642ef-ec15-4a97-905f-fed1ef05f657"},{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2022-06-09"}],"filename":"iken532text.pdf","filesize":[{"value":"5.4 MB"}],"url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2018025/files/iken532text.pdf"},"version_id":"43bb5c10-aa54-4e8d-8b70-77f668fbb247"}]},"item_1617944105607":{"attribute_name":"Degree Grantor","attribute_value_mlt":[{"subitem_1551256015892":[{"subitem_1551256027296":"18001","subitem_1551256029891":"kakenhi"}],"subitem_1551256037922":[{"subitem_1551256042287":"琉球大学","subitem_1551256047619":"ja"}]}]},"item_title":"Raptor and rictor expression in patients with human papillomavirus-related oropharyngeal squamous cell carcinoma","item_type_id":"59","owner":"8","path":["1642838159351","1642838409905"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2022-06-09"},"publish_date":"2022-06-09","publish_status":"0","recid":"2018025","relation_version_is_last":true,"title":["Raptor and rictor expression in patients with human papillomavirus-related oropharyngeal squamous cell carcinoma"],"weko_creator_id":"8","weko_shared_id":-1},"updated":"2022-06-09T01:25:49.218919+00:00"}
