Embryogenesis requires the timely and coordinated activation of developmental regulators. It has been suggested that the recently discovered class of histone demethylases (UTX and JMJD3) that specifically target the repressive H3K27me3 modification play an important role in the activation of "bivalent" genes in response to specific developmental cues. To determine the requirements for UTX in pluripotency and development, we have generated Utx-null ES cells and mutant mice. The loss of UTX had a ...[more]

X-linked H3K27me3 demethylase Utx is required for embryonic development in a sex-specific manner [ChIP-Seq data]

Project description:Embryogenesis requires the timely and coordinated activation of developmental regulators. It has been suggested that the recently discovered class of histone demethylases (UTX and JMJD3) that specifically target the repressive H3K27me3 modification play an important role in the activation of M-bM-^@M-^\bivalentM-bM-^@M-^] genes in response to specific developmental cues. To determine the requirements for UTX in pluripotency and development, we have generated Utx null ES cells and mutant mice. The loss of UTX had a profound effect during embryogenesis. Utx null embryos had reduced somite counts, neural tube closure defects and heart malformation which presented between E9.5 and E13.5. Unexpectedly, homozygous mutant female embryos were more severely affected than hemizygous mutant male embryos. In fact, we observed the survival of a subset of UTX-deficient males which were smaller in size and had reduced life-span. Interestingly, these animals were fertile with normal spermatogenesis. Consistent with a mid-gestation lethality, UTX null male and female ES cells gave rise to all three germ layers in teratoma assays although sex-specific differences could be observed in the activation of developmental regulators in embryoid body assays. Lastly, ChIP-seq analysis revealed an increase in H3K27me3 in Utx null male ES cells. In summary, our data demonstrate sex-specific requirements for this X-linked gene while suggesting a role for UTY during development. Examination of H3K27me3 and H3K4me3 in UtxKO ES cells (V6.5 background) vs UtxFlx (V6.5 background) ES cells grown in LIF containing ES cell media or treated with retinoic acid without LIF.

The H3K27 demethylase Utx facilitates somatic and germ cell epigenetic reprogramming to pluripotency [ChIP-Seq]

Project description:Pluripotency can be induced in somatic cells by ectopic expression of defined transcription factors, however the identity of epigenetic regulators driving the progression of cellular reprogramming requires further investigation. Here we uncover a non-redundant role for the JmjC-domain-containing protein histone H3 methylated Lys 27 (H3K27) demethylase Utx, as a critical regulator for the induction, but not for the maintenance, of primed and naM-CM-/ve pluripotency in mice and in humans. Utx depletion results in aberrant H3K27me3 repressive chromatin demethylation dynamics, which subsequently hampers the reactivation of pluripotency promoting genes during reprogramming. Remarkably, Utx deficient primordial germ cells (PGCs) display a cell autonomous aberrant epigenetic reprogramming in vivo during their embryonic maturation, resulting in the lack of functional contribution to the germ-line lineage. H3K27me3 and H3K4me3 were measured genome-wide in the following cell types: Utx+/Y (WT) and Utx-/Y (KO) mouse ES cells and mouse embryonic fibroblast (MEF) before and after DOX induction (initiating reprogramming by OSKM factors).

UTX regulated genes in mouse embryonic stem cells

Project description:UTX gene is localized on the X chromosome, identified as a demethylase on histone H3 lysine 27. Two independent UTX conditional knockout (cKO) embryonic stem cell lines and two UTX knockout (KO) cell lines were cultured on 0.1% gelatin-coated dishes without feeder cells at desity of 1 million cells/10 cm dish. Cells were cultured overnight and collected. Total RNAs were sequentially purified with Trizol (Invitrogen) and RNeasy kit (Qiagen) and analyzed on Mouse Genome 430 2.0 Array (Affymetrix) at NIDDK Microarray Core Facility following standard protocols.

Polycomb PHF19 binds H3K36me3 and recruits PRC2 and demethylase NO66 to embryonic stem cell genes during differentiation

Project description:The Polycomb group proteins are repressive chromatin modifiers with essential roles in metazoan development, cellular differentiation and cell fate maintenance. How Polycomb proteins access active chromatin in order to confer transcriptional silencing during lineage transitions remains unclear. Here we show that the Polycomb Repressive Complex 2 (PRC2) component PHF19 binds the active chromatin mark H3K36me3 via its tudor domain. PHF19 associates with the H3K36me3 demethylase NO66, and is required to recruit the PRC2 complex and NO66 to stem cells genes during differentiation, leading to PRC2 mediated H3K27 tri-methylation, loss of H3K36me3 and transcriptional silencing. We propose a model whereby PHF19 functions during ES cell differentiation to transiently bind the H3K36me3 mark via its tudor domain, forming essential contact points that allow recruitment of PRC2 and H3K36me3 demethylase activity to active gene loci during their transition to a Polycomb-repressed state. Examination of PHF19 genome-wide binding in mouse embryonic stem cells

KDM5B focuses H3K4 methylation near promoters and enhancers during embryonic stem cell self-renewal and differentiation [ChIP-Seq]

Project description:Pluripotency of embryonic stem (ES) cells is controlled in part by chromatin-modifying factors that regulate histone H3 lysine 4 (H3K4) methylation. However, it remains unclear how H3K4 demethylation contributes to ES cell function. Here, we show that KDM5B, which demethylates lysine 4 of histone H3, co-localizes with H3K4me3 near promoters and enhancers of active genes in ES cells; its depletion leads to spreading of H3K4 methylation into gene bodies and enhancer shores, indicating that KDM5B functions to focus H3K4 methylation at promoters and enhancers. Spreading of H3K4 methylation to gene bodies and enhancer shores is linked to defects in gene expression programs and enhancer activity, respectively, during self-renewal and differentiation of KDM5B-depleted ES cells. KDM5B critically regulates H3K4 methylation at bivalent genes during differentiation in the absence of LIF or Oct4. We also show that KDM5B and LSD1, another H3K4 demethylase, co-regulate H3K4 methylation at active promoters but they retain distinct roles in demethylating gene body regions and bivalent genes. Our results provide global and functional insight into the role of KDM5B in regulating H3K4 methylation marks near promoters, gene bodies, and enhancers in ES cells and during differentiation. ChIP-Seq for KDM5B, H3K4 methylation and H3K27ac in murine shLuc, shKdm5b, shLuc-LSD1i, shKdm5b-LSD1i ES cells, and during differentiation of shLuc and shKdm5b ES cells for 2 days, 3 days, and 4 days without LIF.

RNA-Sequencing of primary myoblasts from mice with a satellite cell specific knockout of the histone demthylase UTX/KDM6A

Project description:The KDM6 histone demethylases (UTX/KDM6A and JMJD3/KDM6B) mediate removal of repressive histone H3K27me3 marks to establish transcriptionally permissive chromatin. Loss of UTX in female mice is embryonic lethal. Unexpectedly, male UTX-null mice escape embryonic lethality due to expression of UTY, a paralog lacking H3K27-demethylase activity. This suggests that UTX plays an enzyme-independent role in development, and challenges the need for active H3K27-demethylation in vivo. However, the requirement for active H3K27-demethylation in stem cell-mediated tissue regeneration remains untested. Using an inducible mouse knockout that ablates UTX in satellite cells, we show that active H3K27-demethylation is necessary for muscle regeneration. Indeed, loss of UTX in satellite cells blocks myofiber regeneration in both male and female mice. Furthermore, we demonstrate that UTX mediates muscle regeneration through its H3K27-demethylase activity using a chemical inhibitor, and a demethylase-dead UTX knock-in mouse. Mechanistically, dissection of the muscle regenerative process revealed that UTX is required for expression of the transcription factor Myogenin that drives differentiation of muscle progenitors. Thus, we have identified a critical role for the enzymatic activity of UTX in activating muscle-specific gene expression during myofiber regeneration, revealing for the first time that active H3K27-demethylation has a physiological role in vivo. Satellite cells were sorted based on Cre-dependent expression of TdT reporter gene. Sorted UTXmKO or UTX WT satellite cells were then induced to differentiate for 24 hrs. RNA was then isolated and subjected to RNA-Seq analysis.
