Divergent lncRNAs that are transcribed in the opposite direction to nearby protein-coding genes comprise a significant proportion (∼20%) of total lncRNAs in mammalian genomes. Through genome-wide analysis, we found that the distribution of this lncRNA class strongly correlates with essential developmental regulatory genes. In pluripotent cells, divergent lncRNAs regulate the transcription of nearby genes. As an example, the divergent lncRNA Evx1as promotes transcription of its neighbor gene, EVX ...[more]

cis regulated role of lncRNA in transcriptional or developmental process (ChIRP-Seq)

Project description:We report that long noncoding RNAs contribute to transcription and developmental process. Thousands of lncRNAs have been identified in the whole genome, and tend to located closely to protein-coding genes. To study position relationship between lncRNA and protein-coding genes, we classified all of lncRNA to several subgroups based on the genome position with their coding neighbors. XH, the head to head subgroup is associated with transcription and development in GO analysis. Here, we knockdown serveral XH lncRNA by shRNA in embryonic stem cells and induce nondirectional differnetiation by removing LIF or neural differnetiation by RA. Knockdown of XH lncRNAs led to uniform downregulation of nearby coding genes, and form regulatory circuits with its nearby coding genes to fine-tune embryonic lineage development. In addition, we also knockout one lncRNA-Evx1as and its nearby protein-coding gene-EVX1 by CRISPR, and get similar results as knockdown.We propose that XH lncRNA may function primarily as 'cis-regulators' of the expression of nearby protein-coding genes, and tend to participate in transcriptional or development regulations as their coding neighbors. All RNA-seq(s) were designed to reveal the differentially expressed genes between wild-type and XH lncRNA knockdown/knockout ESCs during differentiation.

Opposing roles for the lncRNA Haunt and its genomic locus in regulating HOXA gene activation during embryonic stem cell differentiation

Project description:Long noncoding RNAs (lncRNAs) have been implicated in controlling various aspects of embryonic stem cell (ESC) biology, although the functions of specific lncRNAs, and the molecular mechanisms through which they act, remain unclear. Here, we demonstrate discrete and opposing roles for the lncRNA transcript Haunt and its genomic locus in regulating the HOXA gene cluster during ESC differentiation. Reducing or enhancing Haunt expression, with minimal disruption of the Haunt locus, led to up- or down-regulation of HOXA genes, respectively. In contrast, increasingly large genomic deletions within the Haunt locus attenuated HOXA activation. The Haunt DNA locus contains potential enhancers of HOXA activation, whereas Haunt RNA acts to prevent aberrant HOXA expression. This work reveals a multi-faceted model of lncRNA-mediated transcriptional regulation of the HOXA cluster, with distinct roles for a lncRNA transcript and its genomic locus, while illustrating the power of rapid CRISPR/Cas9-based genome editing for assigning lncRNA functions. All RNA-seq(s) were designed to reveal the differentially expressed genes among different stages of ESCs differentiation, or differentially expressed genes between wild-type or Haunt or HOXA mutant cells during RA-induced differentiation. All ChIRP-Seq were used to reveal the DNA or RNA targets of Haunt before or after RA treatment.

Genome-wide maps of KDM5A/JARID1A/RBP2 in mouse ES cells.

Project description:We report the identification of genomic regions bound by KDM5A in mouse embryonic stem (ES) cells and define the functional categories that these regions represent. KDM5A modifies methylated lysine residues on histone tails. We developed anti-KDM5A antibodies and set to detect genomic regions enriched with these antibodies using cells with normal Kdm5a or cells from Kdm5a knockout mice as a control. We found high enrichment with the KDM5A antibodies in normal cells when compared with the genomic background. We found striking identity in the regions enriched with these antibodies in normal cells when compared with the total genomic DNA or with KDM5A ChIP assays from Kdm5a KO cells, showing that the antibodies are specific.

CpG island-mediated global gene regulatory modes in mouse embryonic stem cells

Project description:In order to identify the regions occupied by transcription factors, we performed bio-ChIP followed by massive parallel sequencing (bioChIP-Seq) in mouse ES cells. A total of seven DNA transcription factors including Myc module (Myc, Max, E2F4, Tip60 and Dmap1) and Core module transcription factors (Nanog, Dax1; Kim et al., 2010) were identified. We show that the transcription factors can be classified into several classes according to their occupancies. Our data also show transcription factors in the same class co-occupy the same regulatory elements, share the common characteristics and act together.

AMPK governs lineage specification through Tfeb-dependent regulation of lysosomes

Project description:Faithful execution of developmental programs relies on the acquisition of unique cell identities from pluripotent progenitors, a process governed by combinatorial inputs from numerous signaling cascades that ultimately dictate lineage-specific transcriptional outputs. Despite growing evidence that metabolism is integrated with many molecular networks, how pathways that control energy homeostasis may affect cell fate decisions is largely unknown. Here, we show that AMPK, a central metabolic regulator, plays critical roles in lineage specification. Although AMPK-deficient embryonic stem cells (ESCs) were normal in the pluripotent state, these cells displayed profound defects upon differentiation, failing to generate chimeric embryos and preferentially adopting an ectodermal fate at the expense of the endoderm during embryoid body (EB) formation. AMPK-/- EBs exhibited reduced levels of Tfeb, a master transcriptional regulator of lysosomes, leading to diminished endolysosomal function. Remarkably, genetic loss of Tfeb also yielded endodermal defects, while AMPK-null ESCs over-expressing this transcription factor normalized their differential potential, revealing an intimate connection between Tfeb/lysosomes and germ layer specification. The compromised endolysosomal system resulting from AMPK or Tfeb inactivation blunted Wnt signaling, while up-regulating this pathway restored expression of endodermal markers. Collectively, these results uncover the AMPK pathway as a novel regulator of cell fate determination during differentiation. 2 WT and 2 AMPK DKO ESC lines were differentiated into embryoid bodies (EBs) for various lengths of time (2, 4, 8, and 12 days) in high and low glucose conditions. Both ESC and EB samples were profiled by mRNA-seq to examine how global gene expression changes associated with ESC differentiation are affected by AMPK deletion.

Genome-wide maps of Usp16, ubH2A and gene expression profiles in wild type and Usp16 knock out mouse embryonic stem cells (ESCs) and embryoid bodies (EBs)

Project description:Polycomb Repressive Complex 1 and histone H2A ubiquitination (ubH2A) contribute to embryonic stem cell (ESC) pluripotency by repressing lineage-specific gene expression. However, whether active deubiquitination co-regulates ubH2A levels in ESCs and during differentiation is not known. Here, we report that the histone H2A deubiquitinase Usp16 regulates H2A deubiquitination and gene expression in ESCs, and importantly, is required for ESC differentiation. Usp16 knockout is embryonic lethal in mice, but does not affect ESC viability or identity. Usp16 binds to the promoter regions of a large number of genes in ESCs and Usp16 binding is inversely correlated with ubH2A levels and positively correlated with gene expression levels. Intriguingly, Usp16-/- ESCs fail to differentiate due to ubH2A-mediated repression of lineage-specific genes. Finally, Usp16, but not the enzymatically inactive mutant, rescues the differentiation defects of Usp16-/- ESCs. Therefore, this study identifies Usp16 and H2A deubiquitination as critical regulators of ESC gene expression and differentiation.
