Dynamic and aberrant patterns of H3K4me3, H3K9me3, and H3K27me3 during early zygotic genome activation in cloned mouse embryos.
Somatic cell nuclear transfer (NT) is associated with aberrant changes in epigenetic reprogramming that impede the development of embryos, particularly during zygotic genome activation. Here, we characterized epigenetic patterns of H3K4me3, H3K9me3, and H3K27me3 in mouse NT embryos up to the second cell cycle (i.e. four-celled stage) during zygotic genome activation. In vivo fertilized and parthenogenetically activated (PA) embryos served as controls. In fertilized embryos, maternal and paternal pronuclei exhibited asymmetric H3K4me3, H3K9me3, and H3K27me3 modifications, with the paternal pronucleus showing delayed epigenetic modifications. Higher levels of H3K4me3 and H3K9me3 were observed in NT and PA embryos than in fertilized embryos. However, NT embryos exhibited a lower level of H3K27me3 than PA and fertilized embryos from pronuclear stage 3 to the four-celled stage. Our finding that NT embryos exhibited aberrant H3K4me3, H3K9me3, and H3K27me3 modifications in comparison with fertilized embryos during early zygotic genome activation help to unravel the epigenetic mechanisms of methylation changes in early NT reprogramming and provide an insight into the role of histone H3 in the regulation of cell plasticity during natural reproduction and somatic cell NT.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
