Genome-wide enhancer profiling identifies novel Shh regulated gene targets in the developing cochlear duct

ABSTRACT: The development of the mammalian inner ears is a highly dynamic process that is dependent on the interplay of multiple signaling molecules. Previous studies demonstrated the role of Shh in the initiation and outgrowth of the cochlea. However, the gene targets of Shh in the cochlea largely remain unknown. We show in this study, Shh responsive genes that are loss in the cochlea of Smoecko mutant (Smo null) and upregulated in Shh-P1 mutant embryos through comparative RNA-seq profiling. We performed a genome-wide cis-regulatory element (cRE) study (via ATAC-seq and Gli2 ChIP-seq) and identified potential cREs that are targets of the Shh signaling pathway in the cochlea. Our data unravel novel Shh signaling regulated gene targets that have important functional roles in the development of the cochlea.

Ptch1/Shh signaling control cochlear marginal cell differentiation and stria vascularis formation

Project description:The stria vascularis (SV) is an intricate non-sensory structure composed of multiple cell layers of different origins in the mammalian cochlea. It generates and maintains the endolymph, and therefore is essential for hearing functions. Here, using single cell transcriptomics and transgenic mouse models, we discover that the Shh receptor Ptch1 is required for marginal cell (MC, the epithelial cell layer of SV) differentiation and SV development. During cochlear development, MC differentiation gradually proceeds from cochlear base to apex, resembling the spatiotemporal differentiation pattern of sensory hair cells. Inactivation of Ptch1 leads to an impaired MC differentiation through elevated Gli2 levels, and inhibition of Gli2/Shh signaling activity is a prerequisite for MC differentiation. Single cell transcriptome analyses reveal that MCs are specified as early as E14. Moreover, in the absence of Ptch1, MC precursors are maintained in the progenitor state and differentiation is blocked consequently.

Expression data at 24 hours after the blocking of Shh signaling in tooth germs at embryonic day 14

Project description:The genetic mechanism governing the spatial patterning of teeth still remains to be elucidated. Sonic hedgehog (Shh) is one of key signaling molecules involved in the spatial patterning of teeth. By utilizing maternal transfer of 5E1 (an IgG1 monoclonal antibody against Shh protein) through the placenta to block Shh signaling, we investigated the changes in tooth patterning and in gene expression. We used microarrays to detect specific genes related with Shh signaling in tooth germs and identified some specific genes up- or down-regulated after blocking of Shh signaling activity. Gene-chip expression analysis was performed with RNA from mandibular tooth germs from embryos of pregnant mice at one day after injection of 5E1 (an IgG1 monoclonal antibody against Shh protein; number of replicates =2), 40-1a (an IgG1 monoclonal antibody against β-galactosidase; number of replicates=2), cyclopamine (a specific Smo antagonist; number of replicates=2) or PBS (Phosphate buffered saline; number of replicates=2), using a Affymetrix mouse gene microarray.

A large-scale drug screen identifies selective inhibitors of class I HDACs as a potential therapeutic option for SHH medulloblastoma

Project description:Here we performed a targeted small molecule screen on a stable, SHH-dependent murine MB cell line (SMB21). A subset of the HDAC inhibitors tested significantly inhibit tumor growth of SMB21 cells by preventing SHH pathway activation. Of note, class I HDAC inhibitors were also efficacious in suppressing growth of diverse SMO inhibitor-resistant clones of SMB21 cells. Finally, we show that the novel HDAC inhibitor Quisinostat (JNJ) targets multiple class I HDACs, is well tolerated in mouse models and robustly inhibits growth of SHH MB cells in vivo as well as in vitro. Our data provide strong evidence that Quisinostat (JNJ) or other class I HDAC inhibitors might be therapeutically useful for patients with SHH MB including those resistant to SMO inhibition.

Non-canonical Hedgehog signaling via GLI2 promotes pancreatic stellate cell activation and fibrosis in chronic pancreatitis

Project description:Excessive Hedgehog (Hh) signaling activity contributes to fibrosis in multiple organs, however, its role in pancreatic stellate cell (PSC) activation and fibrosis development during chronic pancreatitis (CP) remains unclear. We demonstrate that GLI2 is upregulated in activated PSCs from CP patients and animal models. Specific deletion of Gli2, but not Smo, significantly alleviated fibrosis in CP models, indicating that CP is driven by non-canonical Hh signaling. Experiments on culture-activated primary PSCs reveal early nuclear translocation and increased GLI2 expression promptly after in vitro culture, with GLI2 being essential for PSC activation. SMO inhibition only reduces GLI2 activation in the short term, while activation of GLI2 by TGF-β/SMAD3 signaling explains the SMO-independent mechanisms leading to Hh activation in PSCs. Altogether, our data demonstrate the activation of the non-canonical Hh pathway in PSCs and indicate that GLI2 represents a promising therapeutic target for CP.

Genome-wide CRISPR-Cas9 knockout screens identify DNMT1 as a druggable dependency in sonic hedgehog medulloblastoma [RNA-seq]

Project description:Sonic hedgehog subgroup of medulloblastoma (SHH-MB) is characterized by aberrant activation of the SHH signaling pathway. An inhibition of the positive SHH regulator Smoothened (SMO) has demonstrated promising clinical efficacy. Yet, primary and acquired resistance to SMO inhibitors limit their efficacy. An understanding of underlying molecular mechanisms of resistance to therapy is warranted to bridge this unmet need. Here, we make use of genome-wide CRISPR-Cas9 knockout screens in SMB21 and DAOY cells, in order to unravel genetic dependencies and drug-related genetic interactors that could serve as alternative therapeutic targets for SHH-MB. Our screens reinforce SMB21 cells as a faithful model system for SHH-MB, as opposed to DAOY cells, and identify members of the epigenetic machinery including DNA methyltransferase 1 (DNMT1) as druggable targets in SHH-dependent tumors. We show that Dnmt1 plays a crucial role in normal murine cerebellar development and is required for SHH-MB growth in vivo. Additionally, DNMT1 pharmacological inhibition alone and in combination with SMO inhibition effectively inhibits tumor growth in murine and human SHH-MB cell models and prolongs survival of SHH-MB mouse models by inhibiting SHH signaling output downstream of SMO. In conclusion, our data highlight the potential of inhibiting epigenetic regulators as a novel therapeutic avenue in SMO-inhibitor sensitive as well as resistant SHH-MBs.

O-GlcNAcylation Promotes Cerebellum Development and Medulloblastoma Oncogenesis via SHH Signaling

Project description:Sonic hedgehog (Shh) signaling plays a critical role in regulating cerebellum development by maintaining the physiological proliferation of granule neuron precursors (GNPs), and its dysregulation leads to the oncogenesis of medulloblastoma. O-GlcNAcylation (O-GlcNAc) of proteins is an emerging regulator of brain function that maintains normal development and neuronal circuitry. Here, we demonstrate that O-GlcNAc transferase (OGT) in GNPs mediate the cerebellum development, and the progression of the Shh-subgroup of medulloblastoma. Specifically, OGT regulates the proliferation of GNPs by activating the Shh signaling pathway via O-GlcNAcylation at S355 of GLI family zinc finger 2 (Gli2), which in turn promotes its deacetylation and transcriptional activity via dissociation from p300, a histone acetyltransferases (HATs). Inhibition of OGT via genetic ablation or chemical inhibition improves survival in a medulloblastoma mouse model. These data uncover a critical role for O-GlcNAc signaling in cerebellar development, and pinpoint a potential therapeutic target for Shh-associated medulloblastoma.
