The role of Dppa3 in mESC through RNA-seq

Project description:Distinct cell types emerge from embryonic stem cells through a precise and coordinated execution of gene expression programs during lineage commitment. This is established by the action of lineage specific transcription factors along with chromatin complexes. Numerous studies focused on epigenetic factors that affect ESC self-renewal and pluripotency. Through our laboratory's previous studies on ESCs pluripotency, we found that Dppa3, as a Naive state marker gene, is of great significance to the transformation of mESCs pluripotency. However, the influence of overexpression of Dppa3 in ESCs on mESCs status has not been determined. Our results show that overexpression of Dppa3 induces global DNA demethylation, which is beneficial to the maintenance of pluripotency, but its differentiation ability is significantly impaired. In mESCs, Dppa3 regulates mESCs pluripotency by inhibiting de novo methylation pathway, maintaining methylation pathway, promoting demethylation pathway Tet2, up-regulating active histone modification and down-regulating heterogeneous histone modification. The 2C-like state of ESCs recapitulates key aspects of the two-cell stage mouse embryo both phenotypically and molecular, which providing a cellular model to investigate the progress of ZGA. Our results found Dppa3 promote facilitate 2C-state conversion.

DPPA3 facilitates genome-wide DNA demethylation in mouse primordial germ cells.

Project description:BackgroundGenome-wide DNA demethylation occurs in mammalian primordial germ cells (PGCs) as part of the epigenetic reprogramming important for gametogenesis and resetting the epigenetic information for totipotency. Dppa3 (also known as Stella or Pgc7) is highly expressed in mouse PGCs and oocytes and encodes a factor essential for female fertility. It prevents excessive DNA methylation in oocytes and ensures proper gene expression in preimplantation embryos: however, its role in PGCs is largely unexplored. In the present study, we investigated whether or not DPPA3 has an impact on CG methylation/demethylation in mouse PGCs.ResultsWe show that DPPA3 plays a role in genome-wide demethylation in PGCs even before sex differentiation. Dppa3 knockout female PGCs show aberrant hypermethylation, most predominantly at H3K9me3-marked retrotransposons, which persists up to the fully-grown oocyte stage. DPPA3 works downstream of PRDM14, a master regulator of epigenetic reprogramming in embryonic stem cells and PGCs, and independently of TET1, an enzyme that hydroxylates 5-methylcytosine.ConclusionsThe results suggest that DPPA3 facilitates DNA demethylation through a replication-coupled passive mechanism in PGCs. Our study identifies DPPA3 as a novel epigenetic reprogramming factor in mouse PGCs.

Comparison of transcriptomes between Marf1+/+ (WT) and Marf1 ENU/ENU (Mutant) fully-grown oocytes (FGO)

Project description:Marf1 (MUT) female mice are infertile and the meiosis of the oocytes are arrest at prophase I. We thought to identify the potential causes of the meiotic arrest phenotype in the mutant oocytes by comparing the transcriptomes of the WT and mutant fully-grown oocytes (from 23-d old mice) that are transcriptional silent. We compared the transcriptomes of WT and MUT FGOs. 3 individual oocyte samples of each genotype (WT and MUT).

ChIP-MS of DPPA3/STELLA in mouse embryonic stem cells

Project description:Genome-wide DNA demethylation is a unique feature of mammalian development and naïve pluripotent stem cells. So far, it was unclear how mammals specifically achieve global DNA hypomethylation, given the high conservation of the DNA (de-)methylation machinery among vertebrates. We found that DNA demethylation requires TET activity but mostly occurs at sites where TET proteins are not bound suggesting a rather indirect mechanism. Among the few specific genes bound and activated by TET proteins was the naïve pluripotency and germline marker Dppa3 (Pgc7, Stella), which undergoes TDG dependent demethylation. The requirement of TET proteins for genome-wide DNA demethylation could be bypassed by ectopic expression of Dppa3. We show that DPPA3 binds and displaces UHRF1 from chromatin and thereby prevents the recruitment and activation of the maintenance DNA methyltransferase DNMT1. We demonstrate that DPPA3 alone can drive global DNA demethylation when transferred to amphibians (Xenopus) and fish (medaka), both species that naturally do not have a Dppa3 gene and exhibit no post-fertilization DNA demethylation. Our results show that TET proteins are responsible for active and - indirectly also for - passive DNA demethylation; while TET proteins initiate local and gene-specific demethylation in vertebrates, the recent emergence of DPPA3 introduced a unique means of genome-wide passive demethylation in mammals and contributed to the evolution of epigenetic regulation during early mammalian development.
