Deskripsi
Here the authors show that a high-fat diet in pregnant mice can release silencing of the imprinted Dlk1 locus in multiple generations of offspring. They found that this occurs via changes in microRNA expression at the locus of interest, as well as transcriptional changes across the genome, in the developing oocytes.
