项目摘要
We tried to investigate the relationship between schizophrenia and the epigenetic events such as the methylation of DNA and the acetylation of histone proteins. First, we examined whether the promoter region of dopamine D2 receptor gene (DRD2) was methylated, using the methylation-sensitive restriction enzyme, Hap II, and the methylation-insensitive enzyme, MspI. The subjects were five pairs of monozygotic twins discordant for DSM-IV schizophrenia (all pairs were male, mean age 42.6 years; all twins had been discordant more than ten years). The genome DNA samples were extracted from lymphocytes by the phenol method. After enzyme digestion, polymerase chain reaction (PCR) was performed, and the size of PCR products was determined using polyacrylamide gel electrophoresis. In four out of five pairs, the level of methylation of the DRD2 promoter region was higher in the affected twin than the normal twin. In one pair, the level was nearly equal in both. In this study, we found some evidenc … More e for the relationship between phenotypic difference in monozygotic twins discordant for schizophrenia and DNA methylation. Therefore in future studies we will try to collect more subjects and use other enzymes.Next, we performed SNPs genotyping and gene expression analysis in monozygotic twins discordant for schizophrenia and compared between twins. The subjects were a pair of monozygotic male twins (age:51), one had DSM-IV schizophrenia, undifferentiated type, and the other had a job, was married, and was well-adapted to social life. The samples were genomic DNA and RNA from the subjects. The SNPs were typed using Affymetrix GeneChip Human Mapping 100K Set (50K Xba Array, 50K Hind Array) and the gene expressions were analyzed by Affymetrix Human Genome U133 Plus 2.0 Array. In SNPs genotyping, forty six SNPs had different signal intensity among all 116204 SNPs between twins. Also, we measured the expression level of 12857 genes. As a results, we detected 4 SNPs that had different signal intensity and located near the 5' end or intron of the genes that showed the different gene expression between twins. By sequencing, we confirmed that there were no alterations of DNA sequences in these regions. Therefore, it could be thought that some epigenetic events caused the change of gene expression. We will investigate the associations between the genes including these SNPs and schizophrenia. Less
我们试图研究精神分裂症与表观遗传事件之间的关系,例如DNA的甲基化和组蛋白的乙酰化。首先,我们使用对甲基化敏感的限制酶,HAP II和甲基化不敏感的酶MSPI检查了多巴胺D2受体基因(DRD2)的启动子区域。这些受试者是DSM-IV精神分裂症的五对单卵双胞胎(所有成对都是男性,平均年龄42.6岁;所有双胞胎都不是十年以上)。通过苯酚法从淋巴细胞中提取基因组DNA样品。酶消化后,进行聚合酶链反应(PCR),并使用聚丙烯酰胺凝胶电泳确定PCR产物的大小。在五对中的四对中,受影响的双胞胎中DRD2启动子区域的甲基化水平高于正常双胞胎。一对,两者的水平几乎相等。在这项研究中,我们发现了一些证据……对于精神分裂症和DNA甲基化不一致的单卵双胞胎的表型差异之间的关系。因此,在未来的研究中,我们将尝试收集更多的受试者并使用其他酶。邻次,我们在单卵双胞胎双胞胎中对精神分裂症不一致进行了SNP基因分型和基因表达分析,并在双胞胎之间进行了比较。他们是一对单子双胞胎(年龄:51),一个人患有DSM-IV精神分裂症,未分化的类型,另一个患有工作,已婚,并且适应社会生活。样品是来自受试者的基因组DNA和RNA。使用Affymetrix Genechip人类映射100K集(50k XBA阵列,50K HIND阵列)键入SNP,并通过Affymetrix人类基因组U133 Plus 2.0阵列分析基因表达。在SNP基因分型中,在双胞胎之间的所有116204 SNP中,有46个SNP具有不同的信号强度。另外,我们测量了12857个基因的表达水平。结果,我们检测到4个具有不同信号强度的SNP,位于基因的5'端或内含子附近,该基因显示了双胞胎之间的基因表达不同。通过测序,我们证实了这些区域中DNA序列没有改变。因此,可以认为某些表观遗传事件导致基因表达的变化。我们将研究包括这些SNP和精神分裂症在内的基因之间的关联。较少的
