RNA-seq analysis of S16 Schwann cells treated with siRNA for Nr2f1/Nr2f2 (CoupTFI/CoupTFII)
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). Overall design: RNA-seq analysis of S16 Schwann cells treated with control and Nr2f1/Nr2f2 siRNA
