α -突触核蛋白(SNCA)基因表达是帕金森病(PD)发病的重要因素。基因增殖可导致遗传性帕金森病,而增加SNCA表达的启动子多态性与散发性帕金森病有关。启动子区CpG甲基化也可能影响SNCA的表达。通过使用培养细胞,我们确定了SNCA CpG岛的一个区域,其中甲基化状态随着SNCA表达的增加而改变。死后脑分析显示,在对照组和帕金森病患者中,前扣带和壳核的CpG区域存在区域非特异性甲基化差异;然而,在PD的黑质中,甲基化明显降低。该CpG区域可能是SNCA基因的内含子调控元件。我们的研究结果表明,控制SNCA表达的一种新的表观遗传调控机制影响PD的发病机制。
Alpha-synuclein (SNCA) gene expression is an important factor in the pathogenesis of Parkinson's disease (PD). Gene multiplication can cause inherited PD, and promoter polymorphisms that increase SNCA expression are associated with sporadic PD. CpG methylation in the promoter region may also influence SNCA expression. By using cultured cells, we identified a region of the SNCA CpG island in which the methylation status altered along with increased SNCA expression. Postmortem brain analysis revealed regional non-specific methylation differences in this CpG region in the anterior cingulate and putamen among controls and PD; however, in the substantia nigra of PD, methylation was significantly decreased. This CpG region may function as an intronic regulatory element for SNCA gene. Our findings suggest that a novel epigenetic regulatory mechanism controlling SNCA expression influences PD pathogenesis.
