Therefore, there is a series of differentially expressed lncRNAs in pulmonary arterial hypertension (PAH) that may be used as markers to diagnose PAH and even predict the prognosis. However, their specific mechanisms remain largely unknown. Therefore, we investigated the biological role of lncRNAs in patients with PAH. First, we screened patients with PAH secondary to ventricular septal defect (VSD) and those with VSD without PAH to assess differences in lncRNA and mRNA expression between the two groups. Our results revealed the significant upregulation of 813 lncRNAs and 527 mRNAs and significant downregulation of 541 lncRNAs and 268 mRNAs in patients with PAH. Then, we identified 10 hub genes in a constructed protein-protein interaction network. Next, we performed bioinformatics analyses, including Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway analysis and subsequently constructed coding-noncoding co-expression networks. We screened lncRNA-TCONS_00008552 and lncRNA-ENST00000433673 as candidate genes and verified the expression levels of the lncRNAs using quantitative reverse-transcription PCR. Although expression levels of lncRNA-TCONS_00008552 in the plasma from the PAH groups were significantly increased compared with the control groups, there was no significant difference in the expression of lncRNA-ENST00000433673 between the two groups. This study bolsters our understanding of the role of lncRNA in PAH occurrence and development and indicates that lncRNA-TCONS_00008552 is a novel potential molecular marker for PAH.<\/jats:p>","DOI":"10.1371\/journal.pone.0281061","type":"journal-article","created":{"date-parts":[[2023,3,9]],"date-time":"2023-03-09T18:50:54Z","timestamp":1678387854000},"page":"e0281061","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":3,"title":["lncRNA-TCONS_00008552 expression in patients with pulmonary arterial hypertension due to congenital heart disease"],"prefix":"10.1371","volume":"18","author":[{"given":"Qi","family":"Yang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Fan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Banghui","family":"Lai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bin","family":"Liao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1079-0459","authenticated-orcid":true,"given":"Mingbin","family":"Deng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2023,3,9]]},"reference":[{"issue":"1","key":"pone.0281061.ref001","doi-asserted-by":"crossref","first-page":"S20","DOI":"10.1016\/j.jacc.2009.04.018","article-title":"Cellular and molecular basis of pulmonary arterial hypertension","volume":"54","author":"NW Morrell","year":"2009","journal-title":"J Am Coll Cardiol"},{"issue":"4","key":"pone.0281061.ref002","doi-asserted-by":"crossref","first-page":"407","DOI":"10.1016\/j.cjca.2014.10.023","article-title":"Adaptation and remodelling of the pulmonary circulation in pulmonary hypertension","volume":"31","author":"M Vaillancourt","year":"2015","journal-title":"Can J Cardiol"},{"issue":"1","key":"pone.0281061.ref003","doi-asserted-by":"crossref","first-page":"79","DOI":"10.1186\/s12943-018-0827-8","article-title":"Circular RNAs function as ceRNAs to regulate and control human cancer progression","volume":"17","author":"Y Zhong","year":"2018","journal-title":"Mol Cancer"},{"issue":"25","key":"pone.0281061.ref004","doi-asserted-by":"crossref","first-page":"D4","DOI":"10.1016\/j.jacc.2013.10.025","article-title":"Relevant issues in the pathology and pathobiology of pulmonary hypertension","volume":"62","author":"RM Tuder","year":"2013","journal-title":"J Am Coll Cardiol"},{"key":"pone.0281061.ref005","doi-asserted-by":"crossref","first-page":"j5492","DOI":"10.1136\/bmj.j5492","article-title":"Pulmonary arterial hypertension: pathogenesis and clinical management","volume":"360","author":"T Thenappan","year":"2018","journal-title":"BMJ"},{"issue":"1","key":"pone.0281061.ref006","doi-asserted-by":"crossref","first-page":"H68","DOI":"10.1152\/ajpheart.00587.2016","article-title":"Notch signaling modulates the electrical behavior of cardiomyocytes","volume":"314","author":"G Borghetti","year":"2018","journal-title":"Am J Physiol Heart Circ Physiol"},{"issue":"4","key":"pone.0281061.ref007","doi-asserted-by":"crossref","first-page":"287","DOI":"10.1016\/j.tcb.2017.11.008","article-title":"Long Noncoding RNA in Cancer: Wiring Signaling Circuitry","volume":"28","author":"C Lin","year":"2018","journal-title":"Trends Cell Biol"},{"issue":"5","key":"pone.0281061.ref008","doi-asserted-by":"crossref","first-page":"3250","DOI":"10.1016\/j.ygeno.2021.07.015","article-title":"Role of mammalian long non-coding RNAs in normal and neuro oncological disorders","volume":"113","author":"N.
