中文摘要
我们分别在体内和胎盘中发现了两个14q32.2印迹中心。种系衍生的初级DLK1-MEG3基因间差异甲基化区(IG-DMR)是受精后衍生的次级MEG3-DMR在体内而不是在胎盘中甲基化模式的上游调节剂,并且IG-DMR和MEG3-DMR分别在胎盘和体内起着印记控制中心的作用。这是第一个证明继发性DMR具有重要的远程印迹调控功能的研究。
英文摘要
We identified two 14q32.2 imprinting centers in the body and the placenta, respectively. The germline-derived primary DLK1-MEG3 intergenic differentially methylated region (IG-DMR) acts as an upstream regulator for the methylation pattern of the postfertilization-derived secondary MEG3-DMR in the body but not in the placenta, and that the IG-DMR and the MEG3-DMR function as imprinting control centers in the placenta and the body, respectively. This is the first study demonstrating an essential long-range imprinting regulatory function for the secondary DMR.
