Abstract:
Objective Recent years,epigenetics research mainly focused on DNA methylation.A growing body of research indicated that DNA methylation may play vital role in etiology of affective disorder.With brief introduction of DNA methylation molecular mechanisms and relevance of DNA methylation to affective disorder,this review focuses on some supporting evidence which are recently emerged in major depressive disorder (MDD) and bipolar disorder related gene DNA methylation.Methods We retrievaled related articles from databases,such as PUBMED,Foreign medical information resources retrieval platform,CNKI,Wanfang database,ect,from 2013-06 to 2015-01.Index strategy TI:[depression OR bipolar disorder OR affective disorder] AND All field:DNA methylation.Reading and narrowing the scope of the articles,the experimental design was understanded,such as DNA from either blood cell or brain parenchyma of sample,methods of methylation detection,gene detected and methylation position,etc.The articles included 168 in English and 32 in Chinese.The whole and retained the articles were red about MDD and bipolar disorder related gene DNA methylation in recent five years.Results Eventually,the article includes 29 articles and two of in Chinese.Most of them are receptor gene epigenetics research associated with disease.Conclusion MDD and bipolar disorder are associated with the higher of DNA methylation levels in multiple gene promoter region,such as GR,BDNF,5-HTR,SLC6A4 and the lower of COMT.This article only from the perspective of affective disorder reviewed the relationship between DNA methylation and diseases.None of other diseases epigenetics research,there is to be perfected in future.
