Sp7/Osterix is restricted to bone-forming vertebrates where it acts as a Dlx co-factor in osteoblast specification [RNA-Seq]

ABSTRACT: Sp7/Osterix is a master regulator of osteoblast specification. To identify transcripts profile in Sp7 positive osteoblast, we performed RNA-seq on primary mouse calvarial cells obtained from Sp7-GFP reporter mice at P1. By hierarchical clustering using transcriptional profiles for chondrocytes and mouse embryonic fibroblasts (MEFs) together with the osteoblast data, we identified cell-type enriched gene expression signatures in osteoblasts, chondrocytes and MEFs. In conjunction with Sp7 ChIP-seq in osteoblast, we identified putative Sp7 targets which underlie the osteoblast regulatory program.

Sp7/Osterix is restricted to bone-forming vertebrates where it acts as a Dlx co-factor in osteoblast specification [ChIP-Seq]

Project description:Sp7/Osterix is a master regulator of osteoblast specification. To identify the Sp7-mediated gene regulatory network in osteoblasts, we performed Sp7 ChIP-seq on primary mouse calvarial osteoblasts comparing the DNA binding profile with the transcriptional profile of Sp7-positive osteoblasts. Analysis of these identified a network of Sp7 regulated osteoblast targets and provides a new insight into the mode of Sp7 action in osteoblast. To further study for the Sp7 mode, we performed ChIP-seq for Sp1, Sp7, Dlx5, as a potential Sp7 partner identified in this study and mutated Sp7 which has mutations in the zinc finger domain, by using in vitro system with a pre-osteoblast mouse cell line, MC3T3E1.

Sp7/Osterix is restricted to bone-forming vertebrates where it acts as a Dlx co-factor in osteoblast specification [ChIP-Seq 2]

Project description:To identify Sp7’s molecular interactions in vivo, we used gene-targeting strategies to generate an Sp7-Biotin-3xFLAG knock-in mouse (Sp7-BioFL mouse). This approach appends a biotin (Bio) recognition motif and three copies of the FLAG (FL) epitope at the C-terminus of the Sp7 protein. To validate this knockin system, we compared ChIP-seq results in the MC3T3E1 osteoblast cell line, introducing Sp7 forms that were epitope-tagged at either the N- (N-terminal FLAG tag; MC3_FLAG-Sp7) or C-terminus (C-terminal Biotin-FLAG tag, as in the in vivo targeted allele; MC3_Sp7-BioFLAG). These data show an extensive overlap, suggesting that FLAG tagging at different positions gives comparable outcomes. Second, we examined ChIP on wild-type calvarial primary osteoblasts (POB) using an anti-Sp7 antibody (POB_Sp7Ab-ChIP). The majority of Sp7-Ab ChIP-seq peaks (95%) overlapped with the larger set identified by Sp7-BioFL ChIP-seq.

The effect of S309W mutation on SP7 genomic binding in chondrocytes

Project description:SP7/Osterix is a transcription factor critical for osteoblast maturation and bone formation. We identidied a missense variant (c.926C>G:p.S309W) in SP7 in a patient with a unique high turnover bone disease. Mice with the corresponding variant similarly showed a complex skeletal phenotype distinct from that of Sp7-null mice. We therefore performed ChIP-Seq in primary chondrocytes to study how the mutation alters the genomic binding of SP7.

Osterix functions downstream of anti-Müllerian hormone signaling to regulate Müllerian duct regression

Project description:The goal of this study was to identify potential AMH-induced genes and regulatory networks controlling regression by RNA-Seq transcriptome analysis of differences in Müllerian Duct mesenchyme between males (AMH signaling on) and females (AMH signaling off) in purified fetal Müllerian Duct mesenchymal cells. This analysis found 82 genes up-regulated in males during MD regression and identified Osterix (Osx)/Sp7, a key transcriptional regulator of osteoblast differentiation and bone formation, as a novel downstream effector of AMH signaling during MD regression.

Sp7/Osterix Is Restricted to Bone-Forming Vertebrates where It Acts as a Dlx Co-factor in Osteoblast Specification.

Project description:In extant species, bone formation is restricted to vertebrate species. Sp7/Osterix is a key transcriptional determinant of bone-secreting osteoblasts. We performed Sp7 chromatin immunoprecipitation sequencing analysis identifying a large set of predicted osteoblast enhancers and validated a subset of these in cell culture and transgenic mouse assays. Sp family members bind GC-rich target sequences through their zinc finger domain. Several lines of evidence suggest that Sp7 acts differently, engaging osteoblast targets in Dlx-containing regulatory complexes bound to AT-rich motifs. Amino acid differences in the Sp7 zinc finger domain reduce Sp7's affinity for the Sp family consensus GC-box target; Dlx5 binding maps to this domain of Sp7. The data support a model in which Dlx recruitment of Sp7 to osteoblast enhancers underlies Sp7-directed osteoblast specification. Because an Sp7-like zinc finger variant is restricted to vertebrates, the emergence of an Sp7 member within the Sp family was likely closely coupled to the evolution of bone-forming vertebrates.

The bone transcription factor Osterix controls extracellular matrix and node of Ranvier related gene expression in oligodendrocytes [RNA-seq]

Project description:Oligodendrocytes are the primary producers of many extracellular matrix (ECM) related proteins found in the central nervous system (CNS), thereby, these cells play a critical role in the determination of brain stiffness, node of Ranvier formation, perinodal ECM deposition and perineuronal net formation. The transcription factors that control ECM related gene expression in oligodendrocytes remain unknown. Here, we found that the transcription factor Osterix (also known as Sp7) binds in proximity to genes important for CNS ECM and node of Ranvier formation and mediates their expression. Oligodendrocyte specific ablation of Sp7 changes ECM composition and brain stiffness, and results in aberrant node of Ranvier formation. Sp7 is known to control osteoblast maturation and bone formation. Our comparative analyses suggests that Sp7 plays a conserved biological role in oligodendrocytes and in bone forming cells, where it mediates brain and bone tissue stiffness by controlling the expression of ECM components.
