The BAF complex does not mediate GLI repression (ATAC-Seq)

ABSTRACT: Purpose: This study seeks to determine whether Smarcc1 mediates GLI repression through chromatin compaction in the limb. Methods: To determine if Smarcc1 mediated GLI repression through chormatin compaction, we used genomic approached to determine changes in chromatin accessibility in control and Smarcc1-conditional mutants. We performed ATAC-seq on individually genotyped anterior forelimbs at E11.5 (40-48s) on control (2 replicates) and PrxCre/+;Smarcc1c/c (3 replicates) embryos. From this experiment we identified ~10,000 differentially accessible regions (FDR<0.05). Results: We find that SMARCC1 is required to maintain chromatin accessibility at thousands of regions within the mouse limb, including most HH-responsive GLI enhancers

The BAF complex does not mediate GLI repression (Gli3 null Cut&RUN)

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.

The BAF complex does not mediate GLI repression (WT Cut&RUN)

Project description:Purpose: This study seeks to identify SMARCC1-bound regions in the mouse limb. Methods: To identify SMARCC1 bound regions in the limb, we performed Cut&Run on pooled anterior and posterior wild-type forelimbs at E11.5 (43-44s; 3 replicates each) and on whole forelimb pairs at E9.5 (21-24s; 2 replicates). We identified 28,082 SMARCC1-bound regions in the anterior forelimb at E11.5, 42,530 regions in the E11.5 posterior limb, and 10,792 SMARCC1-bound regions at E9.5 (FDR<0.05). Results: We find that SMARCC1 is bound to most limb enhancer regions at late stages (E11.5). Additionally, We find that SMARCC1 is bound to the majority of HH-responsive GLI enhancers at E11.5 but only a small portion of GLI enhancers at E9.5.

The BAF complex does not mediate GLI repression (RNA-Seq)

Project description:Purpose: This study seeks to determine whether Smarcc1 co-regulates Hedgehog (HH) target genes in the limb. Methods: To determine if Smarcc1 is required to regulate HH targets, we used genomic approaches to identify Smarcc1-regulated genes within the forelimb. We performed bulk RNA-seq on individually genotyped forelimb-bud pairs at E11.5 (39-40s) on control (2 replicates) and PrxCre/+;Smarcc1c/c (2 replicates) embryos. From this experiment we identified 928 differentially expressed genes (FDR<0.05). Results: We find that while certain HH target genes are co-regulated by SMARCC1, the majority of HH target genes do not require Smarcc1.

GLI transcriptional repression is inert prior to HH pathway activation

Project description:Purpose: Most Hedgehog responsive gene expression is mediated through GLI de-repression. Additionally GLI -repression is proposed to play roles in limb pre-patterning before HH pathway activation. This study evaluates if GLI repression is established prior to HH pathway activation. Methods: To determine if GLI-repression is established prior to pathway activation, we used genomic approaches to study GLI-mediated repression using the mouse developing limb as a model. We identified pre-HH (E9.25, 21-23S) and post-HH (E10.5, 32-25S) GLI3 binding regions using CUT&RUN for endogenous FLAG-tagged GLI3 proteins. Using a combination of ChIP-seq, CUT&RUN, CUT&Tag, ATAC-seq and RNA-seq, we tested whether loss of Gli3 prior to HH signaling was able to de-repress genes and enhancers, as it does after HH signaling. Results: Prior to HH signaling, GLI3 binds to poised, accessible regions with histone deacetylase (HDAC) proteins, similar to post-HH signaling. Despite GLI3 binding to most regions as it does in the post-HH limb, loss of Gli3 is unable to prematurely active target genes or enhancers. Furthermore, we find that GLI3-dependent chromatin compaction does not occur until roughly 10 hours after HH signaling would have normally been induced. Collectively, these results support that GLI repressor proteins are inert prior to HH pathway activation.

Identification of GLI-associated proteins by mass spectrometry

Project description:The Hedgehog signaling pathway is essential for the maintenance and response of several types of stem cells. To study the transcriptional response of stem cells to HH signaling, we searched for proteins binding to GLI proteins, the transcriptional effectors of the HH pathway in mouse embryonic stem (ES) cells. We purified GLI protein complex from an ES cell line that contained a tamoxifen-inducible 3XFLAG-tagged GLI3 repressor allele by anti-FLAG immunoprecipitation and several novel GLI co-factors were identified in the complex by subsequent mass spectrometry analysis.

Genome-wide maps of chromatin accessibility in response to Hh signaling in mouse embryonic forelimb buds

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 to 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: ATAC-seq was done in embryonic day 10.5 posterior limb buds from control and Shh-null embryos to identify GLI enhancers that change chromatin accessibility in response to Hedgehog signaling. Results: We found that Hedgehog signaling regulates the chromatin accessibility of a subset of GLI binding regions. This subset of GLI bound enhancers has reduced accessibility in the absence of Hedgehog signaling and largely overlaps with GLI enhancers that also have reduced H3K27ac in the absence of Hedgehog signaling.

H3K27ac in WT and Shh-/-, and Shh-/-;Gli3-/- E10.5 limb buds

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.

Role of GLI-signaling in the postnatal cardiomyocyte development

Project description:Developmentally, we found downregulation of GLI-signaling in adult human CM, adult murine CM, and in late-stage hiPSC-CM. To investigate the role of GLI-signaling in early-stage cardiomyocyte, we inhibited GLI-signaling and undertook bulkRNAseq analysis at two distinct levels of inhibitions.

Identification of Gli-Act targets in the mouse ventral neural tube by ChIP

Project description:In studies investigating Sonic hedgehog (Shh) mediated patterning of the ventral neural tube, a process where Shh acts as a morphogen, we have investigated the transcriptional network underlying neural tube specification. Adopting an ES-cell based Shh neuronal specification assay (embryoid body; EBs) and a FLAG-tagged Gli protein (a transcriptional effector of the Shh pathway), we identified a number of direct targets of Gli action using Chromatin Immunoprecipitation (ChIP). These results will provide a first survey of the genome level response to this critical signaling input in vertebrate patterning Keywords: ChIP-chip, Gli transcription factors, Gli1, neural specification, mouse
