Project description:We reported loss of HBL1 lnRNA promoted cardiogenesis and the interaction of HBL1-JARID2 in hPSCs. Here we used specific JARID2 antibody to pull down their binding genomic DNAs in hPSCs, respectively, which let us know the potential genes regulated by HBL1-JARID2 during cardiogenesis. 1% Input samples were collected from the same samples after chromatin shearing.

Project description:JARID2 ChIP-seq profile mediated by Xist was investigated using two separate approaches: In the first approach, we use the TX1072 female embryonic stem cell (ESC) line; this is a genetically polymorphic ESC line derived from a mouse with one X-chromosome (X-chr) from the Mus musculus castaneus (Cast) origin and the other of Mus musculus domesticus, C57BL/6 (BL6) strain origin, containing an inducible promoter on the BL6 Xist allele; differentiation and simultaneous induction of Xist for 4 days results in the inactivation of ONLY the BL6-derived X-chr and coating by JARID2 protein. We analysed this ESC line in the undifferentiated state, in which both X-chrs are active (and not coated by JARID2), and also after 4 days of differentiation under Xist inducible conditions, in which cells display one inactive X-chr from BL6 origin and one Xa of the Cast origin; the presence of SNPs allows for the comparison of the degree and localisation of JARID2 enrichment on the inactive X-chr versus the active X-chr; our results suggests that JARID2 is enriched on the inactive X-chr chromosome-wide and not in confined peaks as elsewhere in the genome; This pattern resembles patterns of Xist enrichment published before (Engreitz et al., 2013). In the second approach, we use a male ESC line that carries an inducible Xist transgene (TG) on chromosome 11 (chr11) (Wutz et al., 2000) in the presence (36:11 WT) or the absence of Eed (36:11 Eed-/-) Induction of Xist TG results in Xist coating and enrichment of JARID2 across the chr11, regardless of the presence of Eed when assess by IF/Xist RNA FISH experiments. We compare inducible and uninducible condition in both the 36:11 WT and Eed-/- ESCs; this way, we could assess the Xist-mediated JARID2 recruitment and the effect of the absence of Eed-/-; Our results shows that Xist induction result in a chromosome-wide enrichment of JARID2 on chr11, in a manner that resembles enrichment on the inactive X-chr; this pattern seem to be independent of EED, showing that in contrast to other regions in the genome where JARID2 occupancy is abrogated in the absence of EED, Xist-mediated JARID2 recruitment is not affected.

Project description:The Polycomb Group proteins foster gene repression profiles required for proper development and unimpaired adulthood, and comprise the components of the PRC2 complex including the histone H3 lysine 27 (H3K27) methyltransferase Ezh2. How mammalian PRC2 accesses chromatin is unclear. We find that Jarid2 associates with PRC2 and stimulates its enzymatic activity in vitro. Jarid2 contains a Jumonji C domain, but is devoid of detectable histone demethylase activity. Instead, its artificial recruitment to a promoter in vivo resulted in co-recruitment of PRC2 with resultant increased levels of H3K27me2/3. Jarid2 co-localizes with Ezh2 and MTF2, a homologue of Drosophila Pcl, at endogenous genes in ES cells. Jarid2 can itself bind DNA and its recruitment in ES cells is interdependent with that of PRC2 as Jarid2 knockdown reduced PRC2 at its target promoters, and ES cells devoid of the PRC2 component EED are deficient in Jarid2 promoter access. In addition to the well-documented defects in embryonic viability upon down-regulation of Jarid2, ES cell differentiation is impaired, as is Oct4 silencing. Examination of two factors in ES cells

Project description:Jarid2, a member of the Jumanji family of proteins, is a developmental regulator that is necessary for proper mouse development and stem cell differentiation. To investigate the specific functions of Jarid2 during pancreas development, we generated pancreas-specific Jarid2 mutants. We used microarrays to determine gene expression changes resulting from deletion of the Jarid2 gene in the pancreas.

Project description:We analyzed the overlap in genome wide binding sites between Jarid2 and Suz12 in mouse ES cells and find that Jarid2 and Suz12 peaks have an high degree (90%) of overlap. Moreover we analyzed the effect of Jarid2 down regulation on genome wide Suz12 binding sites and found that Loss of Jarid2 lead to the loss of 70% of Suz12 binding sites and to a 10 Fold reduction in intensity for 90% of Suz12 binding sites. Overall, these results demonstrate that Jarid2 plays an essential role for Suz12 (PRC2 complex) association to DNA. Examination of two different proteins in two different cell lines

Project description:Transitions in competence underlie the ability of CNS progenitors to generate a diversity of neurons and glia. Retinal progenitor cells in mouse generate early-born cell types embryonically and late-born cell types largely postnatally. We find that the transition from early to late progenitor competence is regulated by Jarid2. Loss of Jarid2 results in extended production of early cell types and extended expression of early progenitor genes. Jarid2 can regulate histone modifications, and we find reduction of repressive mark H3K27me3 on a subset of early progenitor genes with loss of Jarid2, most notably Foxp1. We show that Foxp1 regulates the competence to generate early-born retinal cell types, promotes early and represses late progenitor gene expression, and is required for extending early retinal cell production after loss of Jarid2. We conclude Jarid2 facilitates progression of retinal progenitor temporal identity by repressing Foxp1, which is a primary regulator of early temporal patterning.
