Project description:Germline cells reprogram extensive epigenetic modifications to ensure the cellular totipotency of the next generation and prevent accumulation of epimutations. Primordial germ cells (PGCs)1, the common source of both oocytes and sperm, erase genome-wide DNA methylation and histone H3 lysine 9 dimethylation (H3K9me2), a process called genome-wide epigenetic reprogramming2,3. However, little is known about the molecular mechanism of DNA demethylation by developing PGCs. Here we show that overexpression of PRDM14, a critical regulator for specification and early differentiation of PGCs, promotes global DNA demethylation in embryonic stem cells (ESCs). PRDM14 directly represses transcription of de novo DNA methyltransferase, Dnmt3b, but its repression is not sufficient for global DNA demethylation. Comparison of global gene expression profiles between PRDM14-overexpressing ESCs and Dnmts triple mutant ESCs clearly demonstrates that overexpression of PRDM14 activates about half of the genes silenced by DNA methylation in ESCs. Furthermore, PRDM14 directly interacts with TET1, which converts 5-methylcytosine to 5-hydroxymethylcytosine, and DNA demethylation by overexpression of PRDM14 is strongly disturbed by pharmacological inhibitors of the base excision repair (BER) pathway. We propose that formation of a PRDM14/TET1 complex triggers the activation of BER-dependent active demethylation across the whole genome of developing PGCs.

Project description:Gene regulatory networks underlying cellular pluripotency are controlled by a core circuitry of transcription factors, including POU5F1 and NANOG in mammals. However, the evolutionary origin and transformation of pluripotency transcriptional networks have not been elucidated in deuterostomes. PR domain-containing protein 14 (PRDM14) is specifically expressed in pluripotent cells and germ cells, and is required for establishing embryonic stem cells (ESCs) and primordial germ cells (PGCs) in mice. Here, we compared the functions and expression patterns of PRDM14 orthologues within deuterostomes. Amphioxus PRDM14, zebrafish PRDM14, and the combination of sea urchin PRDM14 and CBFA2T compensated for disruption of the mouse Prdm14 gene in terms of maintaining mouse ESC pluripotency. Interestingly, Prdm14 was expressed in motor neurons, but not in germ cells in amphioxus embryos as observed in zebrafish embryos. Therefore, our results suggest that the integration of the PRDM14–CBFA2T complex into the transcriptional network for pluripotency may be essential for stabilizing pluripotency during the early amniote development.

Project description:The pluripotency-associated transcriptional network is regulated by a core circuitry of transcription factors. The PR domain-containing protein, PRDM14, maintains pluripotency by activating and repressing transcription in a target gene-dependent manner. However, the mechanisms underlying dichotomic switching of PRDM14-mediated transcriptional control remains elusive. Here, we identified C-terminal binding protein 1/2 (CtBP1/2) as components of the PRDM14-mediated repressive complex. CtBP1/2 binding to PRDM14 depends on CBFA2T2, a core component of the PRDM14 complex. The loss of Ctbp1/2 impaired the PRDM14-mediated transcriptional repression required for pluripotency maintenance and primed to naïve pluripotency transition. Furthermore, CtBP1/2 also interacted with the PRC2 complexes, and the loss of Ctbp1/2 impaired the PRC2 and H3K27me3 enrichment at the target genes upon PRDM14 overexpression. These results suggest that evidence that the target gene-dependent transcriptional activity of PRDM14 is regulated by partner switching to ensure transition from primed to naïve pluripotency.

Project description:Prdm14 is a PR-domain and zinc-finger protein whose expression is restricted to the pluripotent cells of an early embryo, embryonic stem cells (ESCs), and germ cells. Here we show that Prdm14 safeguards mouse ESC maintenance by preventing induction of extraembryonic endoderm (ExEn) fates. Conversely, Prdm14 overexpression impairs ExEn differentiation during embryoid body (EB) formation. Prdm14 occupies and represses genomic loci encoding ExEn differentiation factors, while also binding to and promoting expression of genes associated with ESC self-renewal. Prdm14-bound genomic regions significantly overlap those occupied by Nanog and Oct4, are enriched in a chromatin signature associated with distal regulatory elements, and contain a unique DNA-sequence motif recognized by Prdm14 in vitro. Our work identifies Prdm14 as a new member of mouse ESC (mESC) transcriptional network, which plays a dual role as a context-dependent transcriptional repressor or activator at distal silencers and enhancers.

FLAG-HA double ChIP (ChIP with FLAG antibody followed by ChIP with HA antibody) was performed with FH-Prdm14 mESCs (Prdm14-ChIPseq) and as a negative control, wildtype mESCs (FLAG-HA_ChIPseq). H3K4me1 ChIPseq in mouse ES cells. Using published H3K4me1 data, we found there is a correlation between Prdm14 binding and H3K4me1 marks. So we obtained our own H3K4me1 data, using the wildtype mESCs.

Project description:Prdm14 is a sequence-specific transcriptional regulator of embryonic stem cell (ESC) pluripotency and primordial germ cell (PGC) formation. It exerts its function, at least in part, through repressing genes associated with epigenetic modification and cell differentiation. Here, we show that this repressive function is mediated through an ETO-family co-repressor Mtgr1, which tightly binds to the pre-SET/SET domains of Prdm14 and co-occupies its genomic targets in mouse ESCs. Structure-guided point mutants abrogated the Prdm14-Mtgr1 association and disrupted Prdm14's function in mESC gene expression and PGC formation in vitro. Altogether, our work uncovers the molecular mechanism underlying Prdm14-mediated repression.
