BNP methylation levels were determined by bisulfite pyrosequencing from plasma samples of RHD patients compared with healthy controls. Several factors influencing the RHD patients were included like age, smoking and cholesterol levels. A fragment of five CG sites (CpG1\u20135) in the promoter region of BNP gene was measured. BNP gene hypermethylation was found in CpG4 and CpG5 in RHD patients compared with non-RHD controls. A significant difference was also observed between RHD patients with long-term administration of warfarin and RHD patients who had recently undergone an operation. Moreover, single CpG4 and CpG5 analysis revealed a significant increase in methylation levels in men. BNP gene body hypermethylation is associated with the risk of RHD, and also influenced by the warfarin anticoagulant therapy of RHD patients after surgery, which could represent novel and promising targets for therapeutic development.<\/jats:p>","DOI":"10.1042\/bsr20160408","type":"journal-article","created":{"date-parts":[[2016,12,6]],"date-time":"2016-12-06T02:15:16Z","timestamp":1480990516000},"update-policy":"https:\/\/doi.org\/10.1042\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Hypermethylation of brain natriuretic peptide gene is associated with the risk of rheumatic heart disease"],"prefix":"10.1042","volume":"37","author":[{"given":"Ni","family":"Li","sequence":"first","affiliation":[{"name":"Ningbo Medical Center Lihuili Hospital, Ningbo University School of Medicine, Ningbo, Zhejiang 315041, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dawei","family":"Zheng","sequence":"additional","affiliation":[{"name":"Ningbo Medical Center Lihuili Hospital, Ningbo University School of Medicine, Ningbo, Zhejiang 315041, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lebo","family":"Sun","sequence":"additional","affiliation":[{"name":"Ningbo Medical Center Lihuili Hospital, Ningbo University School of Medicine, Ningbo, Zhejiang 315041, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Huoshun","family":"Shi","sequence":"additional","affiliation":[{"name":"Ningbo Medical Center Lihuili Hospital, Ningbo University School of Medicine, Ningbo, Zhejiang 315041, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiuying","family":"Zhu","sequence":"additional","affiliation":[{"name":"Ningbo Medical Center Lihuili Hospital, Ningbo University School of Medicine, Ningbo, Zhejiang 315041, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guodong","family":"Xu","sequence":"additional","affiliation":[{"name":"Ningbo Medical Center Lihuili Hospital, Ningbo University School of Medicine, Ningbo, Zhejiang 315041, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qinning","family":"Wang","sequence":"additional","affiliation":[{"name":"Ningbo University School of Medicine, Ningbo, Zhejiang 315211, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Caimin","family":"Zhu","sequence":"additional","affiliation":[{"name":"Ningbo University School of Medicine, Ningbo, Zhejiang 315211, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guofeng","family":"Shao","sequence":"additional","affiliation":[{"name":"Ningbo Medical Center Lihuili Hospital, Ningbo University School of Medicine, Ningbo, Zhejiang 315041, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"288","published-online":{"date-parts":[[2017,1,16]]},"reference":[{"key":"2021111618411975300_B1","doi-asserted-by":"crossref","first-page":"17","DOI":"10.1007\/s10875-009-9332-6","article-title":"Rheumatic fever and rheumatic heart disease: cellular mechanisms leading autoimmune reactivity and disease","volume":"30","author":"Guilherme","year":"2010","journal-title":"J.
