Project description:In mouse embryonic cells, a retinoic acid (RA) stimulation triggers a massive change of gene expression leading the pluripotent, proliferating cells to a lineage-specific differentiation process. The retinoic acid receptor (RAR) plays a key role in this response by inhibiting pluripotency-maintaining genes and simultaneously activating some major actors of cell differentiation. To investigate the mechanism underlying this dual regulation, we performed joint RAR/RXR ChIP-seq and mRNA-seq time series during the first 48 hours of the RA-induced Primitive Endoderm differentiation process in F9 embryonic carcinoma cells. We detected significantly more RAR/RXR binding regions than previous studies and identified among them a handful of typical binding intensity patterns during differentiation. We demonstrate that these patterns are correlated with the coincidental binding of essential transcription factors (TFs) for pluripotency maintenance or PrE differentiation of embryonic stem (ES) cells, as well as the presence of variants of RAR binding motifs. Most importantly, early-bound regions coincide with pluripotency-associated transcription factor binding in ES (like Pou5f1, Sox2, Esrrb and Nr5a2) and display an increased frequency of the DR0 type RAR binding motifs; late-bound sites are associated to the PrE marker Sox17 and are enriched in the canonical DR5 binding motif. Our data offer an unprecedently detailed view on the action of RA in triggering pluripotent cell differentiation. Altogether, this work sheds light on the relocation of RAR/RXR binding sites throughout differentiation, and shows how RAR/RXR progressively shift from DR0 enriched regions, which were specifically identified in undifferentiated models, to canonical RAR binding sites containing loci. Time course (0, 2, 6, 12, 24, 48h) after stimulation of F9 cultured cells by retinoic acid: PanRAR and PanRXR ChIP-seq at 0, 2, 24 and 48h (no replicate); WCE-seq at 0h (no replicate); mRNA-seq at 0, 6, 12, 24, 48h (2 replicates except for time 0h, 4 replicates). Additionally, a control time course (culture in DMSO) sampled at 24 and 48h (no replicates).

Project description:Retinoid homeostasis is critical for normal embryonic development, and both the deficiency and excess of these compounds are associated with congenital malformations. Here we found that SIRT1, the most conserved mammalian NAD+-dependent deacetylase, contributes to the maintenance of homeostatic retinoic acid (RA) signaling and modulates mouse embryonic stem cell (mESC) differentiation. Our data show that SIRT1 deficiency enhances RA signaling, thereby accelerating mES cell differentiation in response to RA. Our findings highlight the importance of SIRT1 in transcriptional regulation of ESC pluripotency and embryogenesis.

Project description:Human embryonic stem cell-reporter line hESC-NKX2.5(eGFP/w) were differentiated to cardiomyocytes (CMs) by utilizing the spin embryoid body method. During differentiation the cells were treated with DMSO or retinoic acid (RA) from day 4-7. At day 31, cells were sorted based on GFP prior to RNA isolation. The results of this microarray demonstrate that CMs treated with RA during differentiation exhibit atrial-like gene expression profile, while DMSO-treated cells show ventricular-like gene profile. CMs treated with DMSO or RA during differentiation were sorted for GFP and analyzed for differential gene expression.

Project description:Retinoic acid (RA) triggers physiological processes by activating heterodimeric transcription factors comprising retinoic acid (RARa,b,g) and retinoid X (RXRa,b,g) receptors. How a single signal induces highly complex temporally controlled networks that ultimately orchestrate physiological processes is unclear. Using an RA-inducible differentiation model we defined the temporal changes in the genome-wide binding patterns of RARg and RXRa and correlated them with transcription regulation. Unexpectedly, both receptors displayed a highly dynamic binding, with different RXRa heterodimers targeting identical loci. Comparison of RARg and RXRa co-binding at RA-regulated genes identified putative RXRa-RARg target genes that were validated with subtype-selective agonists. Gene regulatory decisions during differentiation were inferred from transcription factor target gene information and temporal gene expression. This analysis revealed 6 distinct co-expression paths of which RXRa-RARg is associated with transcription activation, while Sox2 and Egr1 were predicted to regulate repression. Finally, RXRa-RARg regulatory networks were reconstructed through integration of functional co-citations. Our analysis provides a dynamic view of RA signalling during cell differentiation, reveals RA heterodimer dynamics and promiscuity, and predicts decisions that diversify the RA signal into distinct gene-regulatory programs. Transcriptional activity in F9 cells treated with different retinoic acid receptor (RAR) agonists; like all-trans retinoic acid (ATRA), BMS961 (RARg-specific), BMS753 (RARa-specific) or BMS641(RARb-specific); has been evaluated at different time-points (2, 6, 24, 48h) and compared with that found under Ethanol-vehicle treatment conditions (48h treatment).
