Long non-coding RNAs (lncRNAs) have been shown to be involved in the regulation of a wide variety of important biological processes. However, lncRNA mechanism(s) involved in cholestatic liver fibrosis remain unclear. RNA sequence data of hepatic stellate cells from bile duct ligation (BDL) mice or controls were analyzed by weighted gene co-expression network analysis (WGCNA). Based on WGCNA analysis, a competing endogenous RNA network was constructed. We identified LINC00663 and evaluated its function using a panel of assays, including a wound healing assay, a dual-luciferase reporter assay, RNA binding protein immunoprecipitation and chromatin immunoprecipitation. Functional research showed that LINC00663 promoted the activation, migration and epithelial\u2013mesenchymal transition (EMT) of LX-2 cells and liver fibrosis in BDL mice. Mechanistically, LINC00663 regulated splicing factor 2 (SF2)-fibronectin (FN) alternative splicing through the sponging of hsa-miR-3916. Moreover, forkhead box A1 (FOXA1) specifically interacted with the promoter of LINC00663. In summary, we elaborated the fibrotic effects of LINC00663 in human hepatic stellate LX-2 cells and in bile duct-ligated cholestasis mice. We established a FOXA1\/LINC00663\/hsa-miR-3916\/SF2-FN axis that provided a potential target for the diagnosis and targeted therapy of cholestatic liver fibrosis.<\/jats:p>","DOI":"10.3390\/cells12020215","type":"journal-article","created":{"date-parts":[[2023,1,4]],"date-time":"2023-01-04T06:33:44Z","timestamp":1672814024000},"page":"215","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["The Fibrotic Effects of LINC00663 in Human Hepatic Stellate LX-2 Cells and in Bile Duct-Ligated Cholestasis Mice Are Mediated through the Splicing Factor 2-Fibronectin"],"prefix":"10.3390","volume":"12","author":[{"given":"Yang","family":"Chu","sequence":"first","affiliation":[{"name":"Department of Laboratory Medicine, The First Affiliated Hospital of China Medical University, Shenyang 110001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Linan","family":"Bao","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine, The First Affiliated Hospital of China Medical University, Shenyang 110001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yun","family":"Teng","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine, The First Affiliated Hospital, College of Medicine, Zhejiang University, Hangzhou 310003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bo","family":"Yuan","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine, The First Affiliated Hospital of China Medical University, Shenyang 110001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lijie","family":"Ma","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine, The First Affiliated Hospital of China Medical University, Shenyang 110001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ying","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine, The First Affiliated Hospital of China Medical University, Shenyang 110001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hui","family":"Kang","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine, The First Affiliated Hospital of China Medical University, Shenyang 110001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3816","DOI":"10.1364\/BOE.8.003816","article-title":"Differentiation of fibrotic liver tissue using laser-induced breakdown spectroscopy","volume":"8","author":"Sobral","year":"2017","journal-title":"Biomed.
