JAMA Neurol:阿尔茨海默病病理诊断与脑DNA甲基化之间的联系

2014-11-11 MedSci译 MedSci原创

近期的大规模全基因组关联研究发现一些基因变异与阿尔茨海默病(AD)相关;然而在这些AD基因位点上的DNA甲基化能导致疾病的敏感程度还不得而知。因此我们要明确在28个已报道的AD基因位点上的脑DNA甲基化与AD病理诊断之间存在的关联。研究设计:持续基于社区的关于老化与痴呆的临床病理队列研究(宗教团体研究、“拉什”记忆与衰老工程),研究对象为740名剖检病例,年龄在66.0岁到108.3岁之间。研究方

近期的大规模全基因组关联研究发现一些基因变异与阿尔茨海默病(AD)相关;然而在这些AD基因位点上的DNA甲基化能导致疾病的敏感程度还不得而知。因此我们要明确在28个已报道的AD基因位点上的脑DNA甲基化与AD病理诊断之间存在的关联。

研究设计:


持续基于社区的关于老化与痴呆的临床病理队列研究(宗教团体研究、“拉什”记忆与衰老工程),研究对象为740名剖检病例,年龄在66.0岁到108.3岁之间。

研究方法:

通过利用微球分析技术测定个别个体上产生于背外侧前额叶皮层组织核苷酸对(CpG)位点上的DNA甲基化水平。经过一个标准的尸体剖检,我们依据国家研究院老化-里根标准对AD病例进行病理学诊断。

研究结果:

总的来说,有447名研究对象(60.4%)符合AD病理学诊断标准。在SORL1, ABCA7, HLA-DRB5, SLC24A4以及 BIN1上的脑DNA甲基化与AD病理学变化之间存在关联。替换掉AD的病理学的二元性状,是依照两个定量的分子特殊标志,也就是β淀粉样蛋白量和成对的螺旋形细丝状tau蛋白缠结密度。此外,在转录SORL1和ABCA7基因时的RNA表达与成对的螺旋形细丝状tau蛋白缠结密度有关,同时BIN1基因的表达与β淀粉样蛋白量之间也存在关联。

总结:

我们发现在多个AD基因位点上的脑DNA甲基化与AD的病理学改变之间存在关联。以上结果进一步给出证据,证明DNA甲基化的破坏涉及AD的病理过程。
