| Research Abstract |
Parental genome functions in ontogeny are determined by interactions among transcripts from the maternal and paternal genomes, which contain many genes whose expression is strictly dependent on their parental origin as a result of genomic imprinting. Comprehensive recognition of the interactions between parental genomes is important for understanding genomic imprinting in mammalian development. The bi-maternal embryos were produced by the construction of oocytes from fully grown oocytes and nongrowing oocytes that contain double deletions in the H19 differentially methylated region (DMR) and the Dlk1-Dio3 intergenic germline-derived DMR. Through a sequence of studies, we demonstrated that analyses of ng/fg bi-maternal conceptuses helped in elucidating the roles of paternally methylated imprinted genes in mouse ontogeny.
