Project description:DNA methylation is an essential epigenetic regulation for cellular identity. In muscle stem cells, termed satellite cells, DNA methylation patterns are dynamically changed during muscle regeneration. However, how these DNA methylation patterns are maintained remain unclear. Here, we demonstrate that a key epigenetic regulator Uhrf1 (ubiquitin-like with PHD and RING finger domains 1) is activated in proliferating but not expressed in quiescent or differentiated satellite cells. Ablation of Uhrf1 in satellite cell impairs the proliferation and differentiation of satellite cells, leading to failure of muscle regeneration. Loss of Uhrf1 in satellite cells alters transcriptional programs and leads to DNA hypomethylation with the activation of Cdkn1a and Notch signalling. Down-regulation of Cdkn1a and Notch signalling rescued the proliferation and differentiation defect in Uhrf1-deficient satellite cells. Therefore, this study suggest that Uhrf1 can regulate the self-renewal and differentiation of satellite cells through DNA methylation patterning.

Project description:DNA methylation is an essential form of epigenetic regulation responsible for cellular identity. In muscle stem cells, termed satellite cells, DNA methylation patterns are tightly regulated during differentiation. However, it is unclear how these DNA methylation patterns affect the function of satellite cells. We demonstrate that a key epigenetic regulator, ubiquitin like with PHD and RING finger domains 1 (Uhrf1), is activated in proliferating myogenic cells but not expressed in quiescent satellite cells or differentiated myogenic cells in mice. Ablation of Uhrf1 in mouse satellite cells impairs their proliferation and differentiation, leading to failed muscle regeneration. Uhrf1-deficient myogenic cells exhibited aberrant up-regulation of transcripts, including Sox9, with the reduction of DNA methylation level of their promoter and enhancer region. These findings show that Uhrf1 is a critical epigenetic regulator of proliferation and differentiation in satellite cells, by controlling cell type-specific gene expression via maintenance of DNA methylation.

Project description:Transcriptional regulation can be tightly orchestrated by epigenetic regulators. Among these, ubiquitin-like with PHD and RING finger domains 1 (Uhrf1) is reported to have diverse epigenetic functions, including regulation of DNA methylation. However, the physiological functions of Uhrf1 in skeletal tissues remain unclear. Here we show that limb mesenchymal cell-specific Uhrf1 conditional knockout mice (Uhrf1ΔLimb/ΔLimb) exhibit remarkably shortened long bones that have morphological deformities due to dysregulated chondrocyte differentiation as well as proliferation. RNA-seq performed on primary cultured chondrocytes obtained from Uhrf1ΔLimb/ΔLimb mice demonstrates abnormal acceleration of chondrocyte differentiation. In addition, integrative analyses using RNA-seq and MBD-seq reveal that Uhrf1 deficiency cause decreased genome-wide DNA methylation status and reduction in the promoters of specific genes such as Hspb1, which affects chondrocyte differentiation. These results indicate that Uhrf1 governs cell-type specific transcriptional regulation through genome-wide DNA methylation alteration and regulates consequent cell differentiation and skeletal maturation.

Project description:In this study, we directly compared turkey muscle satellite cell gene expression between satellite cells with the gene Matrix Gla Protein (MGP) knocked down by siRNA transfection and those transfected with a lipofectamine control using our 6K Turkey Skeletal Muscle Long Oligo (TSKMLO) microarray (GPL9788). The MGP gene was previously identified as differentially expressed by genetic line and during development of turkey skeletal muscle (Sporer et al., 2011). Gene expression changes were investigated in satellite cells after 72 h of proliferation and after 48 h of differentiation. We identified novel candidate genes and pathways as playing potentially crucial roles in the MGP-mediated effects on the normal processes of proliferation and differentiation in turkey satellite cells previously identified by Velleman et al. (submitted). This experiment was designed to investigate the role of MGP expression in turkey satellite cells during two crucial processes in muscle development: proliferation and differentiation. Satellite cells were isolated from 7-week-old turkeys from the RBC2 line. Cells were transfected with either MGP siRNA or a lipofectamine control; MGP expression was knocked down by over 50% with siRNA transfection (Velleman et al., submitted). Satellite cells were then induced to proliferate for 72h or differentiate for 48h; culture plates from each stage (n=4) were frozen until RNA extraction. Microarrays directly compared the MGP -knockdown to control from each of 4 culture plates and utilized a dye swap to equal 8 arrays for each of the cell developmental stages, proliferation and differentiation, and 16 arrays for the overall experiment investigating the role of MGP expression in satellite cell development and function. Hybridizations were performed in random order.

Project description:In this study, we directly compared turkey muscle satellite cell gene expression between satellite cells with the gene Death-Associated Protein (DAP) knocked down by siRNA transfection and those transfected with a lipofectamine control using our 6K Turkey Skeletal Muscle Long Oligo (TSKMLO) microarray (GPL9788). The DAP gene was previously identified as differentially expressed by genetic line and during development of turkey skeletal muscle (Sporer et al., 2011). Gene expression changes were investigated in satellite cells after 72 h of proliferation and after 48 h of differentiation. We identified novel candidate genes and pathways as playing potentially crucial roles in the DAP-mediated attenuation of the normal processes of proliferation and differentiation in turkey satellite cells previously identified by Velleman et al. (submitted). This experiment was designed to investigate the role of DAP expression in turkey satellite cells during two crucial processes in muscle development: proliferation and differentiation. Satellite cells were isolated from 7-week-old turkeys from the RBC2 line.

Project description:Rheumatoid arthritis (RA) is characterized by chronic synovial inflammation with aberrant epigenetic alterations, leading joint destruction. However, epigenetic regulatory mechanisms underlying RA pathogenesis remain largely unknown. Here we showed that Ubiquitin-like containing PHD and RING finger domains 1 (known as UHRF1) is a central epigenetic regulator to suppressively orchestrate the expression of multiple exacerbation factors in RA. We found remarkable up-regulation of Uhrf1, which is known as a key molecular for maintenance of DNA methylation during cell division 1-3, in murine arthritis tissue, especially synovial fibroblasts (SF). SF-specific Uhrf1 conditional knockout mice indicated more severe arthritic phenotypes with apoptosis resistant SF. Integrative analysis between transcriptome and methylome showed that expression of several cytokines including Ccl20 were up-regulated in Uhrf1-deficient SF. In RA patients, disease activity scores, CCL20 expression, Th17 accumulation, apoptosis resistance were negatively correlated with UHRF1 expression in synovium. Finally, stabilization of UHRF1 by administration of Ryuvidine improved pathogenesis of arthritis model mice. Our results demonstrated that UHRF1 expressed in SF contributes to suppressively orchestrate expression of genes of multiple exacerbating factors under RA progression. Targeting UHRF1 could provide a novel therapeutic strategy for RA.
