DNA methylation is essential for protecting the mammalian germline against transposons. When DNA methylation-based transposon control is defective, meiotic chromosome pairing is consistently impaired during spermatogenesis: How and why meiosis is vulnerable to transposon activity is unknown. Using two DNA methylation-deficient backgrounds, the Dnmt3L and(More)
In mammals, epigenetic reprogramming, the acquisition and loss of totipotency, and the first cell fate decision all occur within a 3-d window after fertilization from the one-cell zygote to the formation of the blastocyst. These processes are poorly understood in molecular detail, yet this is an essential prerequisite to uncover principles of stem cells,(More)
The potential for early embryonic events to program epigenetic states that influence adult physiology remains an important question in health and development. Using the imprinted Zdbf2 locus as a paradigm for the early programming of phenotypes, we demonstrate here that chromatin changes that occur in the pluripotent embryo can be dispensable for(More)
