ZIC2 and ZIC3 promote SWI/SNF recruitment to safeguard progression towards human primed pluripotency [CUT&Tag]

ABSTRACT: ZIC2 and ZIC3 are essential for acquisition and maintenance of primed pluripotency. In this study, we profiled chromatin occupancy of BRG1, EZH2, H3K27ac and H3K4me3 upon concomitant loss of ZIC2 and ZIC3 in primed hESCs, and of BRG1 upon ectopic expression of ZIC2 for increasing periods of time in naïve hESCs.

ZIC2 and ZIC3 promote SWI/SNF recruitment to safeguard progression towards human primed pluripotency [ATAC-Seq]

Project description:ZIC2 and ZIC3 are essential for acquisition and maintenance of primed pluripotency. In this study, we conducted ATAC-seq in single and compound knockout of ZIC2, ZIC3 and ZIC5 primed hESCs, naïve hESCs lacking ZIC3 that inducibly express ZIC2, naive hESCs that inducible express ZIC2 or ZIC3, ZIC3-depleted primed hESCs that were cultured in 5iLAF medium for six days and undergoing reversion to a naive state, naive hESCs expressing ectopic ZIC2 in the presence of a BRG1 PROTAC.

ZIC2 and ZIC3 promote SWI/SNF recruitment to safeguard progression towards human primed pluripotency [RNA-seq]

Project description:ZIC2 and ZIC3 are essential for acquisition and maintenance of primed pluripotency. In this study, we conducted next generation sequencing of polyA-enriched bulk RNA in single and compound knockouts of ZIC2, ZIC3 and ZIC5 primed hESCs, naïve hESCs lacking ZIC3 that inducibly express ZIC2, and primed hESCs that were cultured in 5iLAF medium for six days and undergoing reversion to a naive state.

ZIC2 and ZIC3 promote SWI/SNF recruitment to safeguard progression towards human primed pluripotency [ChIP-seq]

Project description:The primed epiblast acts as a transitional stage between the relatively homogeneous naïve epiblast and the gastrulating embryo. Its formation entails coordinated changes in regulatory circuits driven by strict epigenetic mechanisms. Using a multi-omic approach in human embryonic stem cell models across the spectrum of peri-implantation development, we demonstrate that the transcription factors ZIC2 and ZIC3 have overlapping but essential roles in opening primed-specific enhancers. Together they are essential to facilitate progression to and maintain primed pluripotency. ZIC2/3 achieve their function by recruiting SWI/SNF to chromatin and loss of ZIC2/3 or degradation of SWI/SNF both prevent enhancer activation. Loss of ZIC2/3 results in transcriptome changes consistent with perturbed Polycomb activity and a shift towards the expression of genes linked to mesendoderm differentiation. Additionally, we find an intriguing dependency on the transcriptional machinery for sustained recruitment of ZIC2/3 over a subset of primed-hESC specific enhancers. Taken together, ZIC2 and ZIC3 regulate highly dynamic lineage-specific enhancers and collectively act as key regulators of human primed pluripotency.

Zic2, an enhancer-binding factor required for embryonic stem cell specification

Project description:The Zinc finger protein of the cerebellum 2 (Zic2) is one of the vertebrate homologs of the Drosophila pair-rule gene odd-paired (opa). Our molecular and biochemical studies have demonstrated that Zic2 to preferentially bind to transcriptional enhancers and functions as a cofactor that interacts with the NuRD complex in ES cells. Detailed genome-wide studies demonstrate that Zic2 function with Mbd3/NuRD in regulating the chromatin state and transcriptional output of genes linked to differentiation. Zic2 is dispensable for the selfrenewal of ES cells but is required for proper differentiation, similar to what has been previously reported for Mbd3/NuRD. Our study identifies Zic2 as a key factor in the execution of the pluripotency program with Mbd3/NuRD in ES cells. ChIP-seq of Zic2, Chd4, Mbd3 and Zic3 in mES cells. ChIP-seq of H3K27me3, H3K27ac, H3K4me3, H3K4me1 and PolII in mES cells after Zic2 shRNA and non-targeting shRNA. RNA-seq of mES cells after Zic2, Zic3, Mbd3 and Mta2 shRNA and non-targeting shRNA.

OCT4 cooperates with distinct chromatin remodelers in naive and primed pluripotent states in human [RNA-Seq]

Project description:Understanding the molecular underpinnings of pluripotency is a prerequisite for optimal maintenance and application of embryonic stem cells (ESCs). We mapped the protein-protein interactions of OCT4 in naive and primed hESCs, revealing extensive connections to ATP-dependent nucleosome remodeling complexes. In naive hESCs, OCT4 is associated with both BRG1 and BRM, the two mutually exclusive ATPase subunits of the BAF complex. Genome-wide location analyses and genetic deletion studies reveal that these two enzymes exert a functionally redundant role in transcriptional regulation of blastocyst-specific genes. In contrast, OCT4 cooperates with BRG1 and the transcription factor SOX2 to create an open chromatin architecture at neural lineage-associated genes in primed hESCs. This work offers insight into the regulation of human stem cell identity and reveals how a common transcription factor utilizes differential compositions of the BAF complex in controlling distinct transcriptional programs governing naive vs. primed human pluripotent states.

Oct4 cooperates with distinct ATP-dependent chromatin remodelers in naïve and primed pluripotent states in human [ATAC-seq]

Project description:Understanding the molecular underpinnings of pluripotency is a prerequisite for optimal maintenance and application of embryonic stem cells (ESCs). While the protein-protein interactions of core pluripotency factors have been identified in mouse ESCs, their physical interactome in human ESCs (hESCs) has not been explored thus far. Here we mapped the protein-protein interactions of OCT4 in naive and primed hESCs, revealing extensive connections to ATP-dependent nucleosome remodeling complexes. In naive hESCs, OCT4 is associated with both BRG1 and BRM, the two core ATPases of the BAF complex. Genome-wide location analyses and genetic deletion studies reveal that these two enzymes exert a functionally redundant role in transcriptional regulation of blastocyst-specific genes. In contrast, in primed hESCs OCT4 cooperates with BRG1 and the transcription factor SOX2 to create an open chromatin architecture at neural lineage associted genes. This work offers insight into the regulation of human stem cell identity and reveals how a common transcription factor utilizes differential BAF complex composition to control distinct transcriptional programs in naive and primed hESCs.
