酒精滥用是一个主要的公共健康问题,源于遗传和环境风险因素。大脑表观基因组的改变可能会协调基因表达的变化,从而导致酒精滥用和依赖。通过对人脑组织DNA甲基化的表观基因组关联分析,我们确定了与酒精依赖相关的差异甲基化区域DMR-DLGAP2。DMR-DLGAP2中的甲基化被发现是基因依赖的、等位基因特异性的,并与大脑中的奖赏处理相关。在体外,DMR-DLGAP2的甲基化调节了DLGAP2的表达,与野生型对照相比,Dlgap2缺陷的小鼠表现出更少的酒精消耗。这些结果表明,DLGAP2可能是控制酒精使用和依赖的遗传和表观遗传因素的界面。
Alcohol misuse is a major public health problem originating from genetic and environmental risk factors. Alterations in the brain epigenome may orchestrate changes in gene expression that lead to alcohol misuse and dependence. Through epigenome-wide association analysis of DNA methylation from human brain tissues, we identified a differentially methylated region, DMR-DLGAP2, associated with alcohol dependence. Methylation within DMR-DLGAP2 was found to be genotype-dependent, allele-specific and associated with reward processing in brain. Methylation at the DMR-DLGAP2 regulated expression of DLGAP2 in vitro, and Dlgap2-deficient mice showed reduced alcohol consumption compared with wild-type controls. These results suggest that DLGAP2 may be an interface for genetic and epigenetic factors controlling alcohol use and dependence.
