Several studies have shown that genetic factors play an important role in MG pathogenesis. To gain insight into the epigenetic factors affecting MG, we report here genome\u2010scale DNA methylation profiles of MG. DNA was extracted from eight MG patients and four healthy controls for genome\u2010wide DNA methylation analysis using the Illumina HumanMethylation 850K BeadChip. Verification of pyrosequencing was conducted based on differential methylation positions. Subsequently, C2C12 and HT22 cell lines (derived from mouse) were treated with demethylation drugs. Transcribed mRNA of the screened differential genes was detected using quantitative real\u2010time PCR. The control and MG group were compared, and two key probe positions\u00a0were selected. The corresponding genes were\n CAMK1D<\/jats:italic>\n and\n CREB5<\/jats:italic>\n (\n P<\/jats:italic>\n \u2009<\u20090.05). Similarly, the myasthenic crisis (MC) and non\u2010MC group were compared and four key probe positions were selected. The corresponding genes were\n SAV1, STK3, YAP1<\/jats:italic>\n , and\n WWTR1<\/jats:italic>\n (\n P<\/jats:italic>\n \u2009<\u20090.05). Subsequently, pyrosequencing was performed for verification, revealing that hypomethylation of CAMK1D was significantly different between the MG and control group (\n P<\/jats:italic>\n \u2009<\u20090.001). Moreover, transcription of\n CREB5, PKD, YAP1<\/jats:italic>\n , and\n STK3<\/jats:italic>\n genes in the C2C12 cells was downregulated (\n P<\/jats:italic>\n \u2009<\u20090.05) after drug treatment, but only\n YAP1<\/jats:italic>\n mRNA was downregulated in HT22 cells (\n P<\/jats:italic>\n \u2009<\u20090.05). This is the first study to investigate genome\u2010scale DNA methylation profiles of MG using 850\u2009K BeadChip. The identified molecular markers of methylation may aid in the prevention, diagnosis, treatment, and prognosis of MG.\n <\/jats:p>","DOI":"10.1002\/2211-5463.13656","type":"journal-article","created":{"date-parts":[[2023,5,31]],"date-time":"2023-05-31T03:18:26Z","timestamp":1685503106000},"page":"1375-1389","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Epigenome\u2010wide\n DNA<\/scp>\n methylation analysis of myasthenia gravis"],"prefix":"10.1002","volume":"13","author":[{"given":"Jingjing","family":"Lin","sequence":"first","affiliation":[{"name":"Department of Neurology The Second Affiliated Hospital and Yuying Children's Hospital of Wenzhou Medical University China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Linshuang","family":"Tao","sequence":"additional","affiliation":[{"name":"Department of Nephrology Taizhou First People's Hospital, Affiliated Huangyan Hospital of Wenzhou Medical University China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lu","family":"Deng","sequence":"additional","affiliation":[{"name":"Department of Neurology The Second Affiliated Hospital and Yuying Children's Hospital of Wenzhou Medical University China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruyi","family":"Zhou","sequence":"additional","affiliation":[{"name":"Department of Neurology The Second Affiliated Hospital and Yuying Children's Hospital of Wenzhou Medical University China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuyue","family":"Lou","sequence":"additional","affiliation":[{"name":"Department of Neurology The Second Affiliated Hospital and Yuying Children's Hospital of Wenzhou Medical University China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Songfang","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Neurology The Second Affiliated Hospital and Yuying Children's Hospital of Wenzhou Medical University China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuanyu","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Neurology The Second Affiliated Hospital and Yuying Children's Hospital of Wenzhou Medical University China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chunxing","family":"Lu","sequence":"additional","affiliation":[{"name":"Department of Neurology The Second Affiliated Hospital and Yuying Children's Hospital of Wenzhou Medical University China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peijun","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Neurology The Second Affiliated Hospital and Yuying Children's Hospital of Wenzhou Medical University China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5429-3337","authenticated-orcid":false,"given":"Beilei","family":"Hu","sequence":"additional","affiliation":[{"name":"Department of Neurology The Second Affiliated Hospital and Yuying Children's Hospital of Wenzhou Medical University China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,6,10]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10072-019-04146-1"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1172\/JCI29894"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1474-4422(15)00145-3"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1001\/jamaneurol.2014.4103"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s12035-016-0024-y"},{"key":"e_1_2_11_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2796.2007.01879.x"},{"key":"e_1_2_11_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/path.1024"},{"key":"e_1_2_11_9_1","doi-asserted-by":"publisher","DOI":"10.1038\/nrg3230"},{"key":"e_1_2_11_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaut.2017.05.005"},{"key":"e_1_2_11_11_1","doi-asserted-by":"publisher","DOI":"10.1093\/bioinformatics\/btx513"},{"key":"e_1_2_11_12_1","doi-asserted-by":"publisher","DOI":"10.1093\/bioinformatics\/bts680"},{"key":"e_1_2_11_13_1","doi-asserted-by":"publisher","DOI":"10.1093\/biostatistics\/kxj037"},{"key":"e_1_2_11_14_1","unstructured":"HansenKD(2017)IlluminaHumanMethylationEPICanno.ilm10b4.hg19: annotation for Illumina's EPIC methylation arrays.
