Project description:Purpose: The response to Hedgehog signaling in the limb is driven by GLI bound enhancers and the majority of Hh targets in the developing limb bud are regulated solely by the activity of GLI-repressor. Currently we do not have a comprehensive understanding of how GLI bound enhancers respond Hedgehog signaling. The goal of this study is to identify how GLI bound enhancers are regulated by Hedgehog signaling and specifically by GLI-repressor. Methods: ChIP-seq was performed in Embryonic day 10.5 mouse limb buds from mice with endogenously FLAG tagged Gli3. Results: We identified 7282 GLI3 binding regions in the E10.5 limb bud.

Project description:Purpose: The response to Hedgehog signaling in the limb is driven by GLI bound enhancers. While most Hh targets in the developing limb bud appear to be regulated by the activity of GLI-repressor, the role of GLI activator in this regulation is unclear. Here we assess the roles of GLI activator and repressor in regulating H3K27ac to activate their enhancers. Methods: ChIP-seq was performed in Embryonic day 10.5 mouse limb buds from WT, Shh-/- and Shh-/-Gli3-/- embryos Results: We found that most GLI binding regions can be activated in the absence of both GLI activator and repressor, while a small subset require GLI activator for activity. These indicate that most GLI enhancers in the limb are regulated by GLI repression.

Project description:We used microarrays to identify Pax3 targets during myogenesis in the mouse embryo Mouse embryos were genotyped Pax3GFP/+ or Pax3PAX3-FKHR/GFP and dissected at E10.5 under a fluorescent binocular. The forelimb buds were dissected and dissociated and GFP positive cells were then sorted by flow cytometry before RNA extraction and hybridization on Affymetrix microarrays. We also sorted GFP negative cells.

Project description:Purpose: This study seeks to determine whether GLI3 is required to recruit the SMARCC1 complex to GLI enhancers in the limb. Methods: To determine if Gli3 is required to recruit SMARCC1 to its anhancers, we performed differential chromatin binding to compare SMARCC1 binding in control and Gli3 mutants. We performed Cut&Run for SMARCC1 binding on individually genotyped E11.5 (40-43s) anterior forelimb pairs from control (Gli3+/+; 3 replicates) and Gli3 mutant (Gli3-/-; 4 replicates) embryos. Results: We found that there is no major difference in SMARCC1 binding in Gli3-mutants compared to controls.

Project description:The transcriptome of the anterior handplates of mouse limb buds of Gli3 constitutive and Hoxa13-Cre Gli3 conditional mutant embryos was compared to the transcriptome of limb buds of wild type and Gli3 heterozygote embryos at embryonic day E11.75. All samples carried one copy of the Hoxa13-Cre allele.

Project description:Sonic hedgehog (Shh) signals via Gli transcription factors to direct digit number and identity in the vertebrate limb. We have characterized the Gli-dependent cis-regulatory network through a combination of whole genome ChIP-on-chip and transcriptional profiling of the developing mouse limb. These analyses identified approximately 5,000 high quality Gli3 binding sites, including all known Gli-dependent enhancers. Discrete binding regions exhibit a higher-order clustering, highlighting the complexity of cis-regulatory interactions. Further, Gli3 binds inertly to previously identified neural-specific Gli enhancers, demonstrating the accessibility of their cis-regulatory elements. Intersection of DNA binding data with gene expression profiles predicted 205 putative limb target genes. The supplementary bed file contains all 5,274 high quality binding Gli3 binding sites reported in the paper.

Project description:We report the distribution of RING1B (one of Polycomb group factors) within the genome of mouse embryonic tissues. We prepared the chromatin from 11 dpc embryonic forebrain, midbrain, and forelimb buds and made chromatin precipitation with antibody against RING1B (mouse monoclonal antibody). High-throughput sequencing applied for the ChIP analysis revealed the differential distribution of RING1B protein among embryonic tissues. ChIP analysis of mouse 11 dpc embryonic forebrain, midbrain and forelimb buds against anti-RING1B antibody.
