WitrynaParental genomic imprinting is characterized by the expression of a selected panel of genes from one of the two parental alleles. Recent evidence shows that DNA methylation and histone modifications are responsible for this parent-of-origin-dependent expression of imprinted genes. Witrynainsights into dynamics and regulation of imprinted domains in mouse models. These advances have brought back into focus a finding that was reported early in the imprinting field: the epi-genetic regulation of many imprinted loci is unique in the extraembryonic compared with embryonic lineages [30–33].

WitrynaGenomic imprinting is the phenomenon where the expression of a locus differs between the maternally and paternally inherited alleles. Typically, this manifests as transcriptional silencing of one of the alleles, although many genes are imprinted in a tissue- or isoform-specific manner.
