We speculated that it plays an important role in arterial disease, and therefore studied the role and mechanism of H19 in aortic dissection (AD).<\/jats:p>\n               <jats:p>Methods: The expressions of related genes in human aortic smooth muscle cells (HASMCs) induced by platelet-derived growth factor BB (PDGF-BB) or in the aortic tissue of AD patients\/mice were identified by Western blot and quantitative real-time polymerase chain reaction. The targeting relationship between H19 and miR-193b-3p was predicted and verified by bioinformatics analysis, dual luciferase assay, RNA pull-down assay, RNA immunoprecipitation (RIP), and Pearson correlation coefficient. The H19 and miR-193b-3p effects on the biological functions of tissues and cells were examined by MTT (3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide, thiazolyl blue tetrazolium bromide) assay, wound-healing assay, and Hematoxylin\u2013Eosin (HE) staining.<\/jats:p>\n               <jats:p>Results: LncRNA H19 was abnormally high-expressed in thoracic aorta tissues of AD patients, and it could competitively bind to and inhibit miR-193b-3p. In the PDGF-BB group, the expressions of H19, matrix metallopeptidase (MMP) 2 (MMP-2) and MMP-9 were up-regulated and the expressions of miR-193b-3p, \u03b1-SMA, and SM22\u03b1 were down-regulated; moreover, the proliferation and migration rate of HASMCs were increased. However, H19 silencing reversed the regulation of PDGF-BB on HASMCs. More interestingly, miR-193b-3p inhibitor could partially reverse the effect of H19 silencing. In addition, the above results were verified by animal experiments, showing that shH19 and up-regulated miR-193b-3p could significantly reduce the thoracic aorta pathological damage in AD mice.<\/jats:p>\n               <jats:p>Conclusion: LncRNA H19 regulated smooth muscle cell function by sponging miR-193b-3p and it participated in the development of AD.<\/jats:p>","DOI":"10.1042\/bsr20202298","type":"journal-article","created":{"date-parts":[[2021,1,10]],"date-time":"2021-01-10T14:40:15Z","timestamp":1610289615000},"update-policy":"https:\/\/doi.org\/10.1042\/crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["LncRNA H19 regulates smooth muscle cell functions and participates in the development of aortic dissection through sponging miR-193b-3p"],"prefix":"10.1042","volume":"41","author":[{"given":"Mingming","family":"Ren","sequence":"first","affiliation":[{"name":"Department of Cardiovascular Surgery, Peking University Shenzhen Hospital, 1120 Lianhua Road, Shenzhen City, Guangdong Province, PR China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tao","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Peking University Shenzhen Hospital, 1120 Lianhua Road, Shenzhen City, Guangdong Province, PR China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaolong","family":"Wei","sequence":"additional","affiliation":[{"name":"Department of Vascular Surgery, Shanghai Changhai Hospital, Shanghai, PR China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yizeng","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Peking University Shenzhen Hospital, 1120 Lianhua Road, Shenzhen City, Guangdong Province, PR China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chun","family":"Ouyang","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Peking University Shenzhen Hospital, 1120 Lianhua Road, Shenzhen City, Guangdong Province, PR China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yilian","family":"Xie","sequence":"additional","affiliation":[{"name":"Department of Surgery, School of Medicine, Shantou University, Shantou, PR China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoqiang","family":"Ye","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Peking University Shenzhen Hospital, 1120 Lianhua Road, Shenzhen City, Guangdong Province, PR China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9129-4961","authenticated-orcid":false,"given":"Zhen","family":"Han","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Peking University Shenzhen Hospital, 1120 Lianhua Road, Shenzhen City, Guangdong Province, PR China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"288","published-online":{"date-parts":[[2021,1,22]]},"reference":[{"key":"2021111620373927000_B1","doi-asserted-by":"publisher","first-page":"78","DOI":"10.1136\/heartjnl-2015-308284","article-title":"Aortic dissection: medical, interventional and surgical management","volume":"103","author":"Silaschi","year":"2017","journal-title":"Heart"},{"key":"2021111620373927000_B2","first-page":"193","article-title":"Aortic dissection","volume":"89","author":"Larson","year":"2017","journal-title":"Radiol.
