Project description:Combining an in vitro hNCC differentiation protocol with epigenomic profiling, we provide the first whole-genome characterization of cis-regulatory elements in this highly relevant cell type. With this data at hand, we have characterized the chromatin state and dynamics of all human gene promoters during the course of NCC in vitro differentiation. Most importantly, we have identified a large cohort of active and NCC-specific enhancers, which we showed to be functionally relevant in vivo, in the context of embryonic development. Finally, through sequence analysis of the identified NCC enhancers, we uncovered the orphan nuclear receptors NR2F1 and NR2F2 as novel hNCC transcriptional regulators both in vitro and in vivo. Genome-wide analysis of p300, H3K4me3, H3K4me1, H3K27me3, H3K27ac, NR2F1, NR2F2 and TFAP2A in in vitro differentiated human neural crest cells (hNCC)

Project description:In a previous study, we had compared SOX10-bound regulatory elements in Schwann cells and oligodendrocytes, and we identified a specific enrichment for nuclear receptor motifs at SOX10 binding sites in Schwann cells. We initially focused on NR2F1 and NR2F2 (CoupTF1/CoupTF2) since they are expressed from neural crest through Schwann cell maturity, and found that knockdown of nuclear receptors Nr2f1 and Nr2f2 in primary Schwann cells downregulated genes such as Myelin Basic Protein (Mbp) and Desert Hedgehog (Dhh). In this study, we have elucidated a NR2F-regulated target gene network in Schwann cells, which revealed enrichment for non-myelinating Schwann cell genes. Cut&Run assays in S16 Schwann cells revealed novel, genome-wide binding sites of NR2F1/2 and downstream transcription factors, Retinoid X Receptor (RXRG) and TEA-Domain factor (TEAD1).

In this study, we have elucidated a NR2F-regulated target gene network in Schwann cells, which revealed enrichment for non-myelinating Schwann cell genes. We used Cut&Run in S16 Schwann cells to show novel, genome-wide binding sites of NR2F1/2 and downstream transcription factors, YY1, SREBP1, Retinoid X Receptor (RXRG) and TEA-Domain factor (TEAD1). Our study elucidates the transcriptional cooperation that forms unique enhancer landscapes and the regulatory network that targets non-myelinating Schwann cells.

Project description:We identified 1-deoxysphingosine as a ligand for NR2F1 and NR2F2. To prove physiological relevance after in vitro binding assay we investigated the role of NR2F1 and NR2F2 in cardiomyocyte differentiation. We also used different strategies to manipulate levels of 1-deoxysphingosines and canonical sphingosines in cardiomyocytes derived from human embryonic stem cells. Here we generated both single knockout of NR2F2 and double knockouts of NR2F1 and NR2F2 in human embryonic stem cell line H9. The differentiation of WT, KO and DKO lines into cardiomyocytes was then compared by single-cell RNA-seq analysis.
