Chip-chip from mouse embryonic stem (mES) cells

ABSTRACT: To understand how pluripotency is controlled, we employed a modification of standard ChIP-chip method (biotin-mediated ChIP-chip) to identify targets of nine factors, including somatic cell reprogramming factors (Oct4, Sox2, Klf4, c-Myc) and others (Nanog, Dax1, Rex1, Zpf281, and Nac1) in mouse ES cells. We show the application of In vivo biotinylation mediated ChIP (bioChIP) to global target mapping. Our data also show that differential regulation of target genes correlates with the extent of promoter occupancy by multiple factors in maintaining stem cell pluripotency.

CpG island-mediated global gene regulatory modes in mouse embryonic stem cells

Project description:In order to identify the regions occupied by transcription factors, we performed bio-ChIP followed by massive parallel sequencing (bioChIP-Seq) in mouse ES cells. A total of seven DNA transcription factors including Myc module (Myc, Max, E2F4, Tip60 and Dmap1) and Core module transcription factors (Nanog, Dax1; Kim et al., 2010) were identified. We show that the transcription factors can be classified into several classes according to their occupancies. Our data also show transcription factors in the same class co-occupy the same regulatory elements, share the common characteristics and act together.

Genome-wide gene expression analysis of hNAC1-dependent time course rescue of Nac1 null abnormal reprogrammed cells

Project description:In this study, we dissected the functional contribution of NAC1 in establishing pluripotency during somatic cell reprogramming. We identified a critical role for NAC1 in transcriptionally and post-transcriptionally modulating E-cadherin expression during the generation of iPSCs. In the absence of NAC1 functions, reprogramming is diverted to an anomalous state that can be fully rescued with the re-expression of Nac1.

Pluripotency-state-dependent Role of Dax1 in Embryonic Stem Cells Self-renewal

Project description:DAX1 (also known as Nr0b1) is regarded as an important component of the transcription factor network in mouse embryonic stem cells (ESCs). However, the role and the molecular mechanism of Dax1 in the maintenance of different pluripotency states are poorly understood. Here, we constructed a stable Dax1 knockout (KO) cell line using the CRISPR/Cas9 system to analyze the precise function of Dax1. We reported that 2i/LIF-ESCs had significantly lower Dax1 expression than LIF/serum-ESCs. Dax1KO ES cell lines could be established in 2i/LIF and their pluripotency was confirmed. In contrast, Dax1-null ESCs could not be continuously passaged in LIF/serum due to severe differentiation and apoptosis. In LIF/serum, the activities of the Core module and Myc module were significantly reduced, while the PRC2 module was activated after Dax1KO. The expression of most pro-apoptotic genes and lineage-commitment genes were drastically increased, while the down-regulated expression of anti-apoptotic genes and many pluripotency genes was observed. Our research on the pluripotent state-dependent role of Dax1 provides clues to understand the molecular regulation mechanism at different stages of early embryonic development.

Off-the-shelf proximity labeling

Project description:In this study we developed a new assay to perform proximity biotinylation in cells without the requirement for genetic manipulation or transfection to fuse a biotin ligase to a protein of interest. We show the specificity by targeting H3K9me3 and performing ChIP-seq for the biotin modification. Targeting IgG was used as a control. By doing so, we identified flywch1 as a new protein binding to H3K9me3 regions, which we validated using ChIP-seq (IgG ChIP was used as a control)

Effect of EWS/FLI1 and DAX1 silencing on the gene expression profile of the A673 Ewing cell line

Project description:The molecular hallmark of the Ewing family of tumors is the presence of balanced chromosomal translocations leading to the formation of chimerical transcription factors (i.e. EWS/FLI1) that play a pivotal role in the pathogenesis of Ewing tumors by deregulating gene expression. We have recently demonstrated that DAX1 (NR0B1), an orphan nuclear receptor which was not previously implicated in cancer, is induced by the EWS/FLI1 oncoprotein and is highly expressed in Ewing tumors, suggesting that DAX1 is a biologically relevant target of EWS/FLI1-mediated oncogenesis. In this work we demonstrate that DAX1 is a direct transcriptional target of the EWS/FLI1 oncoprotein through its binding to a GGA-rich region in the DAX1 promoter and show that DAX1 is a key player of EWS/FLI1-mediated oncogenesis. DAX1 silencing using an inducible model of RNA interference induces growth arrest in the A673 Ewing cell line and severely impairs its capability to grow in semisolid medium and form tumors in immunodeficient mice. Gene expression profile analysis demonstrated that about ten percent of the genes regulated by EWS/FLI1 in Ewing cells are DAX1 targets, confirming the importance of DAX1 in Ewing oncogenesis. These findings indicate that DAX1 is an important player in the pathogenesis of the Ewing family of tumors, identify new functions for DAX1 as a cell cycle progression regulator and open the possibility to new therapeutic approaches based on DAX1 function interference.

Transition of embryonic stem cells from ground state pluripotency (RNA-seq)

Project description:Mouse embryonic stem cells were maintained in minimal and chemically-defined culture conditions supporting naive pluripotency. Inhibitors of the Gsk3 (CHIR99021) and Mek/Erk (PD0325901) pathways were withdrawn, cultures maintained for 24 hours, and subsequently sorted by flow cytometry based on fluorescence of a short-half-life Rex1(Zfp42)::GFP reporter into two populations: Rex1-high cells, functionally capable of reversion to naive pluripotency, and Rex1-low cells that have exited the naive state.

Rex1/Zfp42 is dispensable for pluripotency in mouse ES cells

Project description:We showed the function of Rex1 in mouse ES cells as well as in embryos using the conventional gene targeting strategy. Our results clearly indicated that Rex1 function is dispensable for both the maintenance of pluripotency in ES cells and the development of embryos. However, Rex1-/- ES cells showed the defect to induce a subset of the marker genes of visceral endoderm, when differentiated as embryoid body, as found in EC cells. Conclusion: Rex1 should be regarded just as a marker of pluripotency without functional significance like the activity of alkaline phosphatase. Keywords: genetic modification design,reference design,replicate design
