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.
