Ezh2 maintains proliferation, transcriptional integrity, and the timing of late differentiation during mouse retina development

Project description:We investigated the gene expression profile changes after Ezh2 conditional knockout in the mouse retina at E16.5. Loss of Ezh2 leads to up-regulation of PRC2 targeted genes including cell cycle regulators and multiple genes which are not normally expressed in the retina, including many Hox genes. Loss of Ezh2 resulted in a dramatic decline in progenitor proliferation by postnatal day 3, such that there is an early end to neurogenesis, and disruption of laminar organization. Although there are only minor effects on embryonic retinal development, there is accelerated differentiation of several late born cell types postnatally, including photoreceptors and Mueller glia, which become reactive by postnatal day 14. Peripheral retina was dissected at E16.5 from Pax6alpha-Cre:Ezh2fl/+ and Pax6alpha-Cre:Ezh2fl/null mouse embryos. Total RNA was purified and RNA deep sequencing was done using 4 controls and 4 conditional knockout samples.

Proteome analysis of mouse Wdr74-knockout embryos

Project description:Mouse Wdr74-knockout embryos were generated using the CRISPR-Cas9 system. Embryos from the 4-cell stage to the morula stage were collected and treated with acidic Tyrode's solution to remove the zona pellucida. We used 50 embryos per sample at each developmental stage and identified the proteome of mouse Wdr74-knockout embryos by label-free quantification.

The histone demethylase Jarid1b ensures faithful mouse development by protecting developmental genes from aberrant H3K4me3 [ChIP-Seq]

Project description:Embryonic development is tightly regulated by transcription factors and chromatin-associated proteins. H3K4me3 is associated with active transcription and H3K27me3 with gene repression, while the combination of both keeps genes required for development in a plastic state. Here we show that deletion of the H3K4me2/3 histone demethylase Jarid1b (Kdm5b/Plu1) results in major neonatal lethality due to respiratory failure. Jarid1b knockout embryos have several neural defects including disorganized cranial nerves, defects in eye development and increased incidences of exencephaly. Moreover, in line with an overlap of Jarid1b and Polycomb targets genes, Jarid1b knockout embryos display homeotic skeletal transformations typical for Polycomb mutants. Genome-wide analysis demonstrated that normally inactive genes encoding developmental regulators acquire aberrant H3K4me3 in early Jarid1b knockout embryos. H3K4me3 accumulates as embryonic development proceeds, leading to increased expression of neural master regulators in knockouts. Taken together, these results suggest that Jarid1b contributes to mouse development by protecting developmental genes from inappropriate acquisition of active histone modifications. * Lack of Jarid1b leads to major neonatal lethality and defects in neural systems * Jarid1b mutants display homeotic skeletal transformations * H3K4me3 is increased at inactive transcriptional regulators in Jarid1b-/- embryos * Chromatin changes are accompanied by elevated levels of key neural transcription factors Determining H3K4me3 and H3K27me3 in early (E8.5) mouse embryos

Zebrafish 24hpf whole embryo MZezh2mutant

Project description:Polycomb group (PcG) proteins are transcriptional repressors important to maintain cell identity during embryonic development. Ezh2, the catalytic subunit of the Polycomb Repressive Complex 2, is responsible for placing the epigenetic repressive mark histone H3 lysine 27 trimethylation (H3K27me3). In contrast to results in mouse models, zebrafish embryos mutant for both maternal and zygotic ezh2 (MZezh2) can form a normal body plan at 1 day post fertilization (dpf) but die at 2 dpf, exhibiting pleiotropic phenotypes. To elucidate the specificity of PcG-mediated repression during early zebrafish development, we conducted in depth analysis of the transcriptome, epigenome, and proteome of the MZezh2 mutant embryos at 1 dpf. We found that, despite modifications in the epigenetic landscape, transcriptome and proteome analysis revealed only minor changes in gene and protein expression levels.

Expression data from E11.5 mouse branchial arch 1 (BA1) - comparison between Ezh2lox/lox and Wnt1Cre Ezh2lox/lox embryos

Project description:Conditional ablation of Ezh2 in the neural crest lineage results in loss of the neural crest-derived mesenchymal derivatives. In this data sheet we determine gene expression analysis in Ezh2lox/lox and Wnt1Cre Ezh2lox/lox in E11.5 mouse BA1 cells. Conditional ablation of Ezh2 in the neural crest lineage was achieved by crossing Wnt1creEzh2lox/wt mice with Ezh2lox/lox mouse lines. We analyzed a total of 6 samples including 3 biological replicates from Ezh2lox/lox embryos and 3 biological replicates from Wnt1cre Ezh2lox/lox embryos.
