 note = {Imprinted genes in mammals show monoallelic expression dependent<br /> on parental origin and are often associated with differentially methylated regions<br /> (DMRs). There are two classes of DMR: germline DMRs acquire gamete-specific<br /> methylation in either spermatogenesis or oogenesis and maintain the allelic<br /> methylation differences throughout development; secondary DMRs establish<br /> differential methylation patterns after fertilization. Targeted disruption of some<br /> germline DMRs showed that they dictate the allelic expression of nearby<br /> imprinted genes and the establishment of the allelic methylation of secondary<br /> DMRs. However, how the imprinting machinery recognizes germline DMRs is<br /> unknown. As a step toward elucidating the sequence features of the germline<br /> DMRs, I have determined the extents and boundaries of 15 germline<br /> mouse DMRs (including 12 maternally methylated and 3 paternally methylated ones) in<br /> 12.5-dpc embryos and sperm by bisulfite sequencing. I found that the average<br /> size of the DMRs was 2.7 kb and that their average G+C content was 54.2%.<br /> Oligonucleotide content analysis of the DMR sequences revealed that, although<br /> they are generally CpG rich, the paternally methylated DMRs contain less CpGs<br /> than the maternally methylated ones. Furthermore, based on the SOM analysis,<br /> I found that most germline DMRs have features distinct from typical mouse<br /> sequences. My findings provide a basis for the further characterization of DMRs.<br />, application/pdf, 総研大甲第957号},
