Previous findings from our laboratory using the Illumina Infinium Human Methylation450 BeadChip suggested that methylation at the promoter of <jats:italic>SSTR4<\/jats:italic> was one of the major form of DNA modification in alcohol-dependent populations. To investigate whether DNA methylation levels of the <jats:italic>SSTR4<\/jats:italic> promoter influence alcohol-dependent behaviors, genomic DNA was extracted from the peripheral blood sample of 63 subjects with AD and 65 healthy controls, and pyrosequencing was used to verify the results of BeadChip array. Linear regression was used to analyze the correlation between the methylation levels of <jats:italic>SSTR4<\/jats:italic> promoter and the scores of alcohol dependence scales. Gene expression of <jats:italic>SSTR4<\/jats:italic> in brain tissue was obtained from the Genotype-Tissue Expression (GTEx) project and Human Brain Transcriptome database (HBT). We found the methylation levels of <jats:italic>SSTR4<\/jats:italic> in AD group were significantly lower than healthy controls (two-tailed <jats:italic>t<\/jats:italic>-test, <jats:italic>t =<\/jats:italic> 14.723, <jats:italic>p<\/jats:italic> &amp;lt; 0.001). In addition, only weak to moderate correlations between the methylation levels of the <jats:italic>SSTR4<\/jats:italic> promoter region and scale scores of Alcohol Use Disorders Identification Test (AUDIT), Life Events Scale (LES) and Wheatley Stress Profile (WSS) based on linear regression analyses (AUDIT: <jats:italic>R<\/jats:italic><jats:sup>2<\/jats:sup><jats:italic>=<\/jats:italic> 0.35, <jats:italic>p<\/jats:italic> &amp;lt; 0.001; LES: <jats:italic>R<\/jats:italic><jats:sup>2<\/jats:sup> = 0.27, <jats:italic>p<\/jats:italic> &amp;lt; 0.001; WSS: <jats:italic>R<\/jats:italic><jats:sup>2<\/jats:sup> = 0.49, <jats:italic>p<\/jats:italic> &amp;lt; 0.001). The hypomethylated status of <jats:italic>SSTR4<\/jats:italic> may involve in the development of AD and increase the risk of AD persistence in Han Chinese males.<\/jats:p>","DOI":"10.3389\/fgene.2022.915513","type":"journal-article","created":{"date-parts":[[2022,6,9]],"date-time":"2022-06-09T06:57:26Z","timestamp":1654757846000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Promoter Specific Methylation of SSTR4 is Associated With Alcohol Dependence in Han Chinese Males"],"prefix":"10.3389","volume":"13","author":[{"given":"Rongrong","family":"Zhao","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Huihui","family":"Shi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiajun","family":"Yin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhen","family":"Sun","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yahui","family":"Xu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2022,6,9]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"1069","DOI":"10.1111\/j.1360-0443.2008.02213.x","article-title":"Are There Genetic Influences on Addiction: Evidence from Family, Adoption and Twin Studies","volume":"103","author":"Agrawal","year":"2008","journal-title":"Addiction"},{"first-page":"4","volume-title":"Diagnostic and Statistical Manual of Mental Disorders","year":"1994","key":"B2"},{"volume-title":"AUDIT.
