H3K9me3 Impedes Cell Fate Transition between 2C-Like and Pluripotent States [ChIP-seq]

ABSTRACT: A small subgroup of embryonic stem cells (ESCs) exhibit molecular features similar to those of two-cell embryos (2C). Multiple chromatin modifiers associated with H3K9 trimethylation (H3K9me3) have been implicated in the mediation of the 2C-like transition. However, it remains elusive how H3K9me3 is remodeled and its association with totipotent cells. Here, we analyze the genome-wide change in H3K9me3 in 2C-like transitions. We revealed that a large fraction of trophoblast-stem-cell specific enhancers undergoes loss of H3K9me3 exclusively in MERVL+/Zscan4+ cells during 2C-like transitions.

DUX-miR-344-ZMYM2-mediated activation of MERVL LTRs induces a totipotent 2C-like state [ATAC-seq]

Project description:Mouse embryonic stem cells (ESCs) sporadically express preimplantation two-cell-stage (2C) transcripts, including MERVL endogenous retrovirus and Zscan4 cluster genes. Such 2C-like cells (2CLCs) can contribute to both embryonic and extraembryonic tissues when reintroduced into early embryos. We examined global nucleosome occupancy and gene expression in 2CLCs and identified miR-344 as the noncoding molecule that positively controls 2CLC potency. We found that activation of endogenous MERVL or miR-344-2 alone is sufficient to induce 2CLCs with induction of 2C genes and an expanded potency. Mechanistically, miR-344 is activated by the 2C-state driver DUX and post-transcriptionally represses ZMYM2 and LSD1, which recruit the HDAC corepressor to MERVL LTR for transcriptional repression. Consistently, zygotic depletion of Zmym2 compromises the totipotency-to-pluripotency transition during early development. Our studies establish the novel DUX->miR-344--|Zmym2/Lsd1 axis that controls MERVL for expanded stem cell potency.

RBBP4 regulates pluripotent-to-2C-like state transition through modulating heterochromatin assembly (CUT&RUN)

Project description:Cellular totipotency is critical for generating a whole organism, yet how to establish totipotency is still poorly illustrated. Unlike pluripotent stem cells, abundant transposable elements (TEs) are activated in the totipotent cells. Here, we show that histone chaperone RBBP4 but not its homologous RBBP7 is indispensable in maintaining the identity of mouse embryonic stem cells (mESCs). Auxin-induced degradation of RBBP4, but not RBBP7, reprograms pluripotent state to a totipotent-like (also known as 2C-like) state. Mechanistically, RBBP4 could recruit G9a and KAP1 to bind on retrotransposons, especially endogenous retroviruses. RBBP4 degradation reduces the binding of G9a-mediated H3K9me2 on ERVL (particularly MERVL) and KAP1-mediated H3K9me3 on ERV1/ERVK, respectively. Moreover, RBBP4 facilitates nucleosome occupancy through chromatin remodeler CHD4 and RBBP4 depletion leads to attenuation of CHD4 binding and nucleosome occupancy on TEs. Together, our study reveals the important roles of RBBP4 in heterochromatin assembly and its loss activates TEs in mESCs, opening a new way to obtain totipotent cells in vitro.
