Project description:YTHDF2 Suppresses the 2C-like State in Mouse Embryonic Stem Cells
| PRJNA1128685 | ENA
Project description:Mouse embryonic stem cells (ESCs) consist of a rare population of heterogeneous cells which express 2-cell-stage-specific transcripts and are referred to as 2-cell-like cells (2CLCs). Accumulating evidence has demonstrated that transcription factors and epigenetic modifications exert crucial functions in the transition of ESCs to 2CLCs. However, the roles of RNA modification in the regulation of 2C-like state remain elusive. Using Dux-induced 2CLCs system, we examine N6-methyladenosine (m6A) modification landscape in transcriptome-wide, and find that m6A is dynamically regulated during Dux-driven 2C-like reprogramming. Intriguingly, many of 2C-specific transcripts are highly methylated, including Dux and Zscan4 cluster genes. We further identify the m6A reader protein Ythdf2 as a critical regulator of 2C-like state. Depletion of Ythdf2 facilitates robust expressions of 2C transcripts and the transition of ESCs to 2CLCs. Mechanically, Ythdf2 binds to the Dux/Zscan4 transcripts and promotes their degradation through recruiting the key component of RNA deadenylase complex, Cnot1. Consistent with the phenotype of Ythdf2 deficiency, silencing of Cnot1 induces the 2C gene expressions and the transition of ESCs into the 2C-like state. Collectively, our findings reveal novel insights into the epitranscriptomic regulation of the 2C-like state in mouse ESCs.

Project description:Mouse embryonic stem cells (ESCs) show cell-to-cell heterogeneity. A small number of two-cell-like cells (2CLCs) marked by endogenous retrovirus activation emerge spontaneously. The 2CLCs are unstable and they are prone to transiting back to the pluripotent state without extrinsic stimulus. To understand how this bidirectional transition takes place, we performed single-cell RNA sequencing on isolated 2CLCs that underwent 2C-like state exit and re-entry, and revealed a step-by-step transitional process between 2C-like and pluripotent states. Mechanistically, we found that cell cycle played an important role in mediating these transitions by regulating assembly of the nucleolus and peri-nucleolar heterochromatin to influence 2C gene Dux expression. Collectively, our findings provide a roadmap of the 2C-like state entry and exit in ESCs and also a causal role of the cell cycle in promoting these transitions.

Project description:After fertilization of the transcriptionally silent oocyte, expression from both parental chromosomes is launched through zygotic genome activation (ZGA), occurring in the mouse at the 2-cell (2C) stage. Among the first elements to be transcribed are the Dux gene, the product of which induces a wide array of ZGA genes, and a subset of evolutionary recent LINE-1 retrotransposons that regulate chromatin accessibility in the early embryo. The maternally inherited factors that activate Dux and LINE-1 transcription have so far remained unknown. Mouse embryonic stem cells (mESCs) recapitulate some aspects of ZGA in culture, owing to their ability to cycle through a 2C-like stage when Dux, its target genes, and LINE-1 integrants are expressed. Here, we identify the paralog proteins DPPA2 and DPPA4 as necessary for the activation of Dux and LINE-1 expression in mESCs. Since their encoding RNAs are maternally transmitted to the zygote, it is likely that these factors are important upstream mediators of murine ZGA.
