Here, we report methylation status of <i>NFATC1</i> and <i>FOS</i> genes in post- and premenopausal women. In this study, 30 premenopausal and 35 postmenopausal women were included. Methylation sensitive-high resolution melting (MS-HRM) analysis was used for identification of <i>NFATC1</i> and <i>FOS</i> genes methylation. The <i>NFATC1</i> gene was methylated in 11 of the 35 postmenopausal women, and the <i>FOS</i> gene was methylated in six of the postmenopausal women (<i>p</i> >0.005). Here, we found statistically significant association between unmethylation of the <i>NFATC1</i> gene and postmenopausal status. This result explains the epigenetic regulation of osteoclasts during the menopausal transition, and for the first time, our results can be used for epigenetic explanation of postmenopausal osteoporosis in the literature.

The vitamin D receptor (VDR) and the Fey receptor IIA (FcγRIIA), are implicated in the etiology of AITD. This study was conducted to examine the implication of <i>VDR</i> rs7975232 and <i>FCGR2A</i> rs 1801274 variations in the susceptibility and the prognosis of AITD in the Tunisian population. The rs7975232 and rs1801274 (R131H) polymorphisms were analyzed in 162 controls and 162 AITD patients (106 HT and 56 GD) by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and amplification of refractory mutation system-PCR (ARMS-PCR), respectively. No significant difference was demonstrated for the rs7975232 between patients and controls. However, a significant association was shown between the rs1801274 polymorphism and AITD or HT in the dominant (<i>p</i> = 0.03 or <i>p =</i> 0.01), codominant (<i>p =</i> 0.019 or <i>p =</i> 0.026) and allelic (<i>p =</i> 0.011 <i>or p =</i> 0.012) models. The rs7975232 was associated with the absence or the presence of anti-thyroglobulin antibody, with the age of AITD and GD patients during the first diagnosis (<i>p =</i> 0.01 and <i>p</i> = 0.009, respectively) and with a high T4 level at the beginning of HT disease. However, the <i>FCGR2A</i> gene polymorphism was associated with a low T4 level at the beginning of GD disease. In conclusion, this study indicates that only the <i>FCGR2A</i> variation could be related to AITD and HT susceptibility and that <i>VDR</i> and <i>FCGR2A</i> gene variations constitute factors to prognosticate the severity of AITD, HT and GD.</p>","PeriodicalId":55403,"journal":{"name":"Balkan Journal of Medical Genetics","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2020-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/01/c3/bjmg-23-069.PMC7474221.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38402550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
