Imprinting is an epigenetic modification that is reprogrammed in the germ line and leads to the monoallelic expression of some genes. Imprinting involves DNA methylation. Maternal imprint is reset during oocyte growth and maturation. In vitro maturation (IVM) of oocytes may, therefore, interfere with imprint acquisition and/or maintenance. To evaluate if(More)
The use of round spermatids that are fully active at the transcriptional level to create zygotes (i.e. round spermatid injection; ROSI) raises the question regarding the downregulation of all specific genes that are transcribed from the paternal genome at fertilization. In this study, we show that protamine 1 and 2 mRNAs, which are specific to the round(More)
