Acute type A aortic dissection (ATAAD) is one of the most lethal cardiovascular diseases, and its molecular mechanism remains unclear. Methods. Differentially expressed genes (DEGs) between ATAAD and control were detected by limma R package in GSE52093, GSE153434, GSE98770, and GSE84827, respectively. The coexpression network of DEGs was identified by the WGCNA package. Enrichment analysis was performed for module genes that were positively correlated with ATAAD using clusterProfiler R package. In addition, differentially methylated markers between aortic dissection and control were identified by ChAMP package. After comparing with ATAAD-related genes, a protein-protein interaction (PPI) network was established based on the STRING database. The genes with the highest connectivity were identified as hub genes. Finally, differential immune cell infiltration between ATAAD and control was identified by ssGSEA. Results. From GSE52093 and GSE153434, 268 module genes were obtained with consistent direction of differential expression and high correlation with ATAAD. They were significantly enriched in T cell activation, HIF-1 signaling pathway, and cell cycle. In addition, 2060 differentially methylated markers were obtained from GSE84827. Among them, 77 methylation markers were ATAAD-related DEGs. Using the PPI network, we identified MYC, ITGA2, RND3, BCL2, and PHLPP2 as hub genes. Finally, we identified significantly differentially infiltrated immune cells in ATAAD. Conclusion. The hub genes we identified may be regulated by methylation and participate in the development of ATAAD through immune inflammation and oxidative stress response. The findings may provide new insights into the molecular mechanisms and therapeutic targets for ATAAD.<\/jats:p>","DOI":"10.1155\/2021\/6697848","type":"journal-article","created":{"date-parts":[[2021,4,13]],"date-time":"2021-04-13T23:24:49Z","timestamp":1618356289000},"page":"1-14","source":"Crossref","is-referenced-by-count":16,"title":["Identification of Molecular Regulatory Features and Markers for Acute Type A Aortic Dissection"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9445-3075","authenticated-orcid":true,"given":"Rui","family":"Lian","sequence":"first","affiliation":[{"name":"Graduate School of Peking Union Medical College, Beijing, China"},{"name":"Emergency Department, China-Japan Friendship Hospital, Beijing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guochao","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of General Surgery, China-Japan Friendship Hospital, Beijing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3011-0051","authenticated-orcid":true,"given":"Shengtao","family":"Yan","sequence":"additional","affiliation":[{"name":"Emergency Department, China-Japan Friendship Hospital, Beijing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0551-1080","authenticated-orcid":true,"given":"Lichao","family":"Sun","sequence":"additional","affiliation":[{"name":"Emergency Department, China-Japan Friendship Hospital, Beijing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1728-3847","authenticated-orcid":true,"given":"Guoqiang","family":"Zhang","sequence":"additional","affiliation":[{"name":"Graduate School of Peking Union Medical College, Beijing, China"},{"name":"Emergency Department, China-Japan Friendship Hospital, Beijing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ebiom.2019.09.041"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.21037\/acs.2016.05.05"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.23736\/S0021-9509.17.09883-4"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.18632\/aging.101033"},{"issue":"6","key":"5","doi-asserted-by":"crossref","first-page":"155","DOI":"10.1055\/s-0039-3401810","article-title":"Repair of acute type-A aortic dissection in the present era: outcomes and controversies","volume":"7","author":"E.
