为了更好地了解人类卵子发生和植入前发育过程中的转录调控,我们定义了阶段特异性转录,这表明卵裂阶段具有高度的独特性。在这里,我们提出了多条证据表明,真兽特异性,多拷贝逆转录基因,DUX 4,编码转录因子,激活数百个内源性基因(如ZSCAN 4,ZFP 352,KDM 4 E)和逆转录病毒元件(MERVL/HERVL家族),定义了小鼠和人类的切割特异性转录程序。值得注意的是,小鼠Dux表达对于将小鼠胚胎干细胞转化为双细胞胚胎样(“2C样”)细胞是必要且足够的,在此通过“2C”基因和重复元件的再活化、POU 5 F1蛋白和染色中心的丢失以及染色质景观(通过ATAC-seq评估)转化为与小鼠双细胞胚胎非常相似的状态来测量。综上所述,我们提出小鼠DUX和人DUX 4作为切割/“2C”状态的主要驱动因素。
To better understand transcriptional regulation during human oogenesis and pre-implantation development, we defined stage-specific transcription, which revealed the cleavage stage as highly distinctive. Here, we present multiple lines of evidence that a eutherian-specific, multi-copy retrogene, DUX4, encodes a transcription factor which activates hundreds of endogenous genes (e.g. ZSCAN4, ZFP352, KDM4E) and retroviral elements (MERVL/HERVL-family) that defines the cleavage-specific transcriptional programs in mouse and human. Remarkably, mouse Dux expression is both necessary and sufficient to convert mouse embryonic stem cells into two-cell embryo-like (‘2C-like’) cells, measured here by the reactivation of ‘2C’ genes and repeat elements, the loss of POU5F1 protein and chromocenters, and by the conversion of the chromatin landscape (assessed by ATAC-seq) to a state strongly resembling mouse two-cell embryos. Taken together, we propose mouse DUX and human DUX4 as major drivers of the cleavage/‘2C’ state.
