Oocyte-derived histone H3 lysine 27 methylation controls gene expression in the early embryo

Nature Structural & Molecular Biology, Published online: 7 September 2017; doi:10.1038/nsmb.3456

The monoallelic expression of many imprinted genes in mammals depends on DNA methylation marks that originate from the germ cells. Recent studies in mice and fruit flies evoke a novel, transient mode of genomic imprinting in which oocyte-acquired histone H3 Lys27 trimethylation (H3K27me3) marks are transmitted to the zygote and modulate the allele specificity and timing of gene expression in the early embryo.

卵母细胞衍生的组蛋白H3赖氨酸27甲基化控制早期胚胎中的基因表达

卵母细胞衍生的组蛋白H3赖氨酸27甲基化控制早期胚胎中的基因表达

《自然结构与分子生物学》,在线发布:2017年9月7日;doi:10.1038 / nsmb.3456

哺乳动物中许多印迹基因的单等位基因表达取决于源自生殖细胞的DNA甲基化标记。最近对小鼠和果蝇的研究唤起了一种新的,短暂的基因组印迹模式,其中卵母细胞获得的组蛋白H3 Lys27三甲基化(H3K27me3)标记被传递至合子,并调节等位基因特异性和早期胚胎中基因表达的时机。
