Time point RNA-seq of Dux over expression samples reveals different transcriptomes of Dux induction in mESC

ABSTRACT: Prevous study has discoverd 2CLC trancriptome and MERVL can be up-regulated by Dux over expression,but rarely has been found about the whole procedure of Dux-induced 2C-entry and exit process and whether this system can reflect the natural 2-cell embryo development,so we we defined different time point transcription after Dux over expression,and try to establish a link between gene expression profile between gene dynamics in different Dux over expression time point and in early mouse embryo development

Zfp352 over expression chip-seq result

Project description:Previous study has determined Dux regulates 2CLC trancriptome via binding and activating MERVL,but the mechanism about the change happned during the 2C-exit process are rarely determined.In this study,we try to illustrate how ZFP352 binds genome location to regulate its downstream trancriptome and 2C-exit process.And make some conclusion and hypothesis about ZFP352 co-binding and interact with other trancription factor:Dux,etc to regulate 2C-exit.

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.

Obox4 secures zygotic genome activation upon loss of Dux

Project description:We report that the multicopy mouse homeobox gene Obox4 encodes a transcription factor that redundantly drives ZGA. OBOX4 is highly expressed in mouse 2-cell embryos. Obox4 or Dux single knockdown is tolerated by embryogenesis, whereas Obox4/Dux double knockdown completely compromises embryonic development. Genome-wide epigenetic profiling reveals that OBOX4 binds MERVL LTRs and murine endogenous retrovirus with lysine tRNA primer (MERVK) LTRs and mediates deposition of active histone modifications.

RNA-sequencing in mESCs with overexpression of mCherry-tagged DUX and DUX domain derivatives

Project description:To investigate the requirement of DUX domains for target gene expression, we created clonal stable cell lines in Dux-/- mouse embryonic stem cells and expressed constructs for 12 hours with 0.25 ug/mL doxycycline We then performed gene expression profiling analysis using data obtained from RNA-seq of 11 different cell lines at one time point

Assessment of functional overlap between mouse Dux and human DUX4 in vitro and in vivo

Project description:We report both DUX4 and Dux toxicity depend upon their ability to bind DNA and activate transcription. Chromatin immunoprecipitation of V5 epitope tagged human DUX4 and mouse Dux was performed in human myoblasts was analyzed using ChIP-Seq to identify their subsequent binding sites. We found that DUX4 and Dux bind 4-8% of identical sequences, while majority of the binding sites are unique to either DUX4 or Dux. Although small, this overlap could be due to their conserved abilioty to regualte primordial pathways that were essential for life and therefore maintained in both proteins despite their separate evolutionary paths. We performed ChIP-Seq analysis of human myoblasts transfected with plasmids encoding either epitope tagged human DUX4 (1 sample) and mouse Dux (1 sample). Illumina sequencing libraries were prepared from the ChIP and Input DNA, then resulting DNA libraries were quantified and sequenced and aligned to the human genome (hg19).
