The purpose of this study was to investigate the effects of CP ingestion on the liver, which controls lipid metabolism in the body. Male BALB/cCrSlc mice were bred with the AIN-93M diet containing 14 % casein or the AIN-93M-based low-protein diet containing 10 % casein or a diet containing 6 % casein+4 % CP for 10 weeks (n 12/group). Total, free and esterified cholesterol levels in the blood decreased in the CP group. DNA microarray analysis of the liver revealed that expressions of genes related to lipid metabolic processes such as the PPAR signalling pathway and fatty acid metabolism increased in the CP group compared with the 10 % casein group. The expressions of several genes involved in steroid metabolic process, including Cyp7a1 and Cyp8b1, were decreased, despite being targets of transcriptional regulation by PPAR. These data suggest that lipid metabolism in the liver is altered by CP ingestion, and the decrease in blood cholesterol levels in the CP group is not due to enhancement of the steroid metabolic process. On the other hand, expressions of genes related to the unfolded protein response (UPR) significantly decreased at the mRNA level, suggesting that CP ingestion lowers endoplasmic reticulum stress. Indeed, protein levels of phosphorylated inositol-requiring enzyme 1 decreased after CP ingestion. Taken together, CP affects the broader pathways in the liver – not only lipid metabolism but also UPR.","subitem_description_type":"Abstract"}]},"item_2_publisher_36":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Cambridge University Press"}]},"item_2_relation_11":{"attribute_name":"ISBN","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"0007-1145","subitem_relation_type_select":"ISBN"}}]},"item_2_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1017/S0007114516004384","subitem_relation_type_select":"DOI"}}]},"item_2_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© The Authors 2017"}]},"item_2_version_type_19":{"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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Tometsuka, Chisa"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Koyama, Yoh-ichi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ishijima, Tomoko"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Toyoda, Tsudoi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Teranishi, Miki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takehana, Kazushige"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"Abe, Keiko"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nakai, Yuji"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-08-08"}],"displaytype":"detail","filename":"R-2018-82_takehana.pdf","filesize":[{"value":"697.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"R-2018-82_takehana.pdf","url":"https://rakuno.repo.nii.ac.jp/record/5663/files/R-2018-82_takehana.pdf"},"version_id":"dc5a6368-f208-4256-88c2-ff6b9e4d4022"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Collagen peptide","subitem_subject_scheme":"Other"},{"subitem_subject":"Liver","subitem_subject_scheme":"Other"},{"subitem_subject":"Lipid metabolism","subitem_subject_scheme":"Other"},{"subitem_subject":"Unfolded protein response","subitem_subject_scheme":"Other"},{"subitem_subject":"DNA microarray","subitem_subject_scheme":"Other"},{"subitem_subject":"Collagen peptide","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Liver","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Lipid metabolism","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Unfolded protein response","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"DNA microarray","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Collagen peptide ingestion alters lipid metabolism-related gene expression and the unfolded protein response in mouse liver","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Collagen peptide ingestion alters lipid metabolism-related gene expression and the unfolded protein response in mouse liver"}]},"item_type_id":"2","owner":"3","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-08-08"},"publish_date":"2019-08-08","publish_status":"0","recid":"5663","relation_version_is_last":true,"title":["Collagen peptide ingestion alters lipid metabolism-related gene expression and the unfolded protein response in mouse liver"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-19T07:54:17.824531+00:00"}
