ATAC-seq in TX1072 XXΔXic and XO mESCs during differentiation

ABSTRACT: Developmental genes are controlled by complex cis-regulatory landscapes that integrate multiple signals to ensure the correct spatio-temporal expression pattern. To investigate the underlying regulatory principles, we use the Xist locus as a model, which encodes the master regulator of X-chromosome inactivation. Xist is upregulated at the primed pluripotent state in a female-specific manner, thus integrating developmental cues and X-dosage information. It remains poorly understood how these signals are decoded by the ~800kb genomic region that controls Xist. While a series of repressive cis-regulatory elements have been identified, the distal enhancers that activate Xist transcription remain largely unknown. Here we use ATAC-seq to profile DNA accessibility within the X inactivation center at the onset of random X-chromosome inactivation using an endogenous cell model of the inactive (TX 1072 XXΔXic) and active (TX 1072 XO) X chromosome.

RNA-seq in TX1072 XO mESCs during differentiation

Project description:As the master regulator of X-chromosome inactivation (XCI), the Xist RNA is expressed nearly ubiquitously in female mice. Xist is only absent in the germ line and at the pluripotent state. Xist is generally assumed to be expressed “by default” in females, while being actively repressed in the few tissues where it is silent. Whether activating mechanisms also contribute remained largely unknown. Through a pooled CRISPR screen we identify the GATA family of transcription factors as potent direct activators of Xist. We describe a GATA-responsive regulatory element (RE79), located ~100 kb upstream of the Xist promoter. In cell lines derived from the two extraembryonic lineages, XEN and TS cells, where imprinted Xist expression is maintained, RE79 is bound by different sets of GATA factors expressed in those tissues. Here we use RNA-seq on differentiating XO mouse embryonic stem cells as a reference for gene expression during early differentiation.

RNAseq TX1072 WT and HDAC3KO

Project description:During development, changes in gene transcription are accompanied by changes in chromatin modification but the order and causality of events often remain unclear. Here we address this question using X-chromosome inactivation (XCI), which entails chromosome-wide gene silencing and heterochromatin formation. We initiate XCI in female, mouse embryonic stem cells by inducing Xist expression and monitor subsequent changes in transcription and chromatin modification by allele-specific TTseq and ChIPseq respectively. An unprecedented temporal resolution has enabled us to define early alterations in chromatin that are induced upon Xist RNA coating. Xist-induced repression begins with histone deacetylation, which involves the histone deacetylase HDAC3 and occurs before efficient loss of H3K4me3 and H3K4me1 modifications. Polycomb-associated repressive histone marks accumulate rapidly, starting with PRC1-associated H2AK119Ub and followed by PRC2-associated H3K27me3. However, polycomb accumulates initially at large premarked domains, some of which correspond to Xist entry sites, and then spreads into genes. We also show that spreading can only ensue when transcriptional silencing has occurred. These results establish a detailed epigenomic time course for XCI and reveal a hierarchy of events with chromatin playing an important role in transcriptional silencing of the X chromosome.

A conserved noncoding locus modulates random monoallelic Xist expression across a TAD boundary

Project description:Topologically associating domains (TADs) are thought to restrict the action of distal cis-regulatory elements, such as enhancers, to target gene promoters within the same TAD. Here we discover that a cis-regulatory element of Xist is located almost 200kb away from its promoter and across a TAD boundary. This element, the promoter of a noncoding RNA, Linx, opposes Xist up-regulation in cis and influences the choice of X chromosome to be inactivated. Even though Linx lies in the same TAD as Xist’s antisense Tsix locus, we show that the repressive action of Linx on Xist is independent of Tsix. Furthermore, this Xist regulatory action is independent of Linx transcript or of its transcription. Finally, we demonstrate that Linx cis-regulatory repressive element is well conserved in mammals, unlike Tsix, suggesting that it represents an ancestral mechanism for random monoallelic Xist expression. Our study uncovers a novel regulatory axis for X-chromosome inactivation and a new class of cis-regulatory effects that rely on TAD partitioning to modulate developmental decisions.

RNAseq in Dppa2 knockout or wildtype TX1072 ESC during and after Xist over-expression

Project description:To understand the role of DPPA2 in epigenetic memory during X-Chromosome reactivation (XCR) we employed inducible Xist hybrid female embryonic stem cell line (TX1072, hybrid Bl6/Cast). Wild type or Dppa2 knockout TX1072 cells were cultured, in three or two independent biological replicates, respectively, in presence of DOX (1ug/ml) for 6 days to induce Xist overexpression and X-Chomosome inactivation (XCI) on the Bl6 allele. DOX was then washed out to silence Xist and XCR was followed in a time-series at 1, 3 or 7 days after DOX removal. Cell pellets were harvested at the following timepoints: -DOX, +DOX, 1d D-wo, 3d D-wo and 7d D-wo. RNA was extracted and 250 ng used for PolyA mRNA library preparation and Next generation sequencing.
