In the intestine, the deregulation of the epithelial barrier contributes to the development of sepsis by triggering continuous exposure to harmful factors. However, sepsis induced epigenetic changes in gene-regulation networks within intestinal epithelial cells (IECs) remain unexplored. In this study, we analyzed the expression profile of microRNAs (miRNAs) in IECs isolated from a mouse model of sepsis generated via cecal slurry injection. Among 239 miRNAs, 14 miRNAs were upregulated, and 9 miRNAs were downregulated in the IECs by sepsis. Upregulated miRNAs in IECs from septic mice, particularly miR-149-5p, miR-466q, miR-495, and miR-511-3p, were seen to exhibit complex and global effects on gene regulation networks. Interestingly, miR-511-3p has emerged as a diagnostic marker in this sepsis model due to its increase in blood in addition to IECs. As expected, mRNAs in the IECs were remarkably altered by sepsis; specifically, 2248 mRNAs were decreased, while 612 mRNAs were increased. This quantitative bias may be possibly derived, at least partly, from the direct effects of the sepsis-increased miRNAs on the comprehensive expression of mRNAs. Thus, current in silico data indicate that there are dynamic regulatory responses of miRNAs to sepsis in IECs. In addition, the miRNAs that were increased with sepsis had enriched downstream pathways including Wnt signaling, which is associated with wound healing, and FGF/FGFR signaling, which has been linked to chronic inflammation and fibrosis. These modifications in miRNA networks in IECs may lead to both pro- and anti-inflammatory effects in sepsis. The four miRNAs discovered above were shown to putatively target LOX, PTCH1, COL22A1, FOXO1, or HMGA2, via in silico analysis, which were associated with Wnt or inflammatory pathways and selected for further study. The expressions of these target genes were downregulated in sepsis IECs, possibly through posttranscriptional modifications of these miRNAs. Taken together, our study suggests that IECs display a distinctive miRNA profile which is capable of comprehensively and functionally reshaping the IEC-specific mRNA landscape in a sepsis model.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_7_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"本文/Department of Molecular Pathobiology and Cell Adhesion Biology, Mie University Graduate School of Medicine, 2-174 Edobashi, Tsu, Mie 514-8507, Japan","subitem_description_type":"Other"},{"subitem_description":"17p","subitem_description_type":"Other"}]},"item_7_dissertation_number_60":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲医学第2240号"}]},"item_7_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"三重大学"}]},"item_7_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.3390/cells12050726","subitem_relation_type_select":"DOI"}}]},"item_7_text_31":{"attribute_name":"出版者（ヨミ）","attribute_value_mlt":[{"subitem_text_value":"ミエダイガク"}]},"item_7_text_63":{"attribute_name":"ノート","attribute_value_mlt":[{"subitem_text_value":"Cells 2023, 12, 726に掲載"}]},"item_7_text_65":{"attribute_name":"資源タイプ（三重大）","attribute_value_mlt":[{"subitem_text_value":"Doctoral Dissertation / 博士論文"}]},"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":"CAIDENGBATE, SIQINGAOWA","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-05-13"}],"filename":"2023DM0316.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","url":{"label":"2023DM0316.pdf","objectType":"fulltext","url":"https://mie-u.repo.nii.ac.jp/record/2000767/files/2023DM0316.pdf"},"version_id":"21748b9c-29fb-47b0-865c-f295643c0cf6"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"sepsis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"cecal slurry injection","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"inflammation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"intestinal epithelial cell","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"miRNA","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":"MicroRNA Profiles in Intestinal Epithelial Cells in a Mouse Model of Sepsis","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"MicroRNA Profiles in Intestinal Epithelial Cells in a Mouse Model of Sepsis","subitem_title_language":"en"}]},"item_type_id":"7","owner":"15","path":["1694066935734"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-05-13"},"publish_date":"2024-05-13","publish_status":"0","recid":"2000767","relation_version_is_last":true,"title":["MicroRNA Profiles in Intestinal Epithelial Cells in a Mouse Model of Sepsis"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2024-05-13T00:30:49.380002+00:00"}
