Project description:SOX transcription factors have important roles during astrocyte and oligodendrocyte development, but how glial genes are specified and activated in a sub-lineage specific fashion remains unknown. To address this question, we have defined glial specific gene expression in the developing spinal cord using single-cell RNA-sequencing. Moreover, conducting ChIP-seq analyses we show that these glial gene sets are extensively preselected already in multipotent neural precursor cells through the prebinding by SOX3. In the subsequent lineage-restricted glial precursor cells, astrocyte genes become additionally targeted by SOX9 at DNA-regions strongly enriched for Nfi binding-motifs, whereas oligodendrocyte genes become prebound by SOX9 only, at sites that during oligodendrocyte maturation are targeted by SOX10. Interestingly, reporter gene assays and functional studies in the spinal cord revealed that SOX3 binding represses the synergistic activation of astrocyte genes by SOX9 and NFIA, whereas oligodendrocyte genes are activated in a combinatorial manner by SOX9 and SOX10. These genome-wide studies demonstrate how sequentially expressed SOX proteins act on lineage-specific regulatory DNA-elements to coordinate glial gene expression both in a temporal and sub-lineage specific fashion.

Project description:Ptf1a is a lineage-specific basic-helix-loop-helix transcription factor critical in the development of both the pancreas and nervous system. How one transcription factor controls diverse programs of gene expression is a fundamental question in developmental biology. To uncover molecular strategies for the program-specific functions of Ptf1a, we identified bound genomic regions in vivo during development of both tissues. A majority of regions bound by Ptf1a are tissue-specific, lie near genes needed for proper formation and maturation of each tissue, and reflect regions of open chromatin.M-BM- M-BM- Information for the specificity of Ptf1a binding and function is encoded in the DNA surrounding the Ptf1a-bound sites, since Ptf1a-bound regions are sufficient to direct tissue-restricted reporter expression when tested in transgenic mice. Fox and Sox factors were identified as lineage specific modifiers ofM-BM- Ptf1a binding, sinceM-BM- binding motifs for these factors are enriched in Ptf1a-bound regions in pancreas and neural tube, respectively. Although Ptf1a and Foxa2 co-localize to sites in embryonic pancreas and can act synergistically in cell transfection assays, biochemical experiments detected no physical interaction between the two factors. These findingsM-BM- indicateM-BM- that lineage-specific chromatin landscapes likely constrain the functions of Ptf1a, and identify Fox and Sox gene families as part of this process.

Project description:Neural cell fate specification is a highly regulated process in which stem cells sequentially possess the transcriptional profile changed and give raise to particular cell lineages such as neuron and glial cells. The NTERA2 cell line is one of the well-characterized hEC cells that can be used as a model system for identifying the regulatory network during human pluripotent stem cells differentiated toward the neural lineage. It has been demonstrated that DDX5 and DDX17, as transcriptional co-regulator, can play a role in various cellular mechanisms depending on their interaction with the different types of transcription factors. Here, we performed ChIP-seq for DDX5 and DDX17 to identify their preferential binding targets during stage transition from pluripotent to neural cell lineage.

Project description:HUES24 cell line was nucleofected with POU5f1 cDNA to overexpress OCT4; This leads to the formation of mesendodermal cells Short- and Long-scales intra- and inter-chromosomal interactions are linked to gene transcription, but the molecular event underlying these structures and how it affects cell fate decision during embryonic development are poorly understood. One of the first embryonic cell fate decisions (i.e mesendoderm determination) is driven by the POU factor OCT4, acting in concert with the high mobility group genes SOX-2 and SOX-17. Here, we identify novel chromatin remodelling mechanism and enhancer function driven by both OCT4 and SALL4 that mediate cell fate switching. We found that OCT4 alters the higher-order chromatin structure at both Sox-2 and Sox-17 loci. OCT4 titrates out cohesin and switches the Sox-17 enhancer from a locked (within an inter-chromosomal Sox-2 enhancer/CTCF/cohesin loop) to an active (within an intra-chromosomal Sox-17 promoter/enhancer/cohesin loop) state. SALL4 concomitantly mobilizes the polycomb complexes at the Soxs loci. Thus, OCT4/SALL4-driven cohesin-and polycombs-mediated changes in higher order chromatin structure mediate instruction of early cell fate in embryonic cells.
