Project description:GDF11 treatment leads to bone loss in mice and strongly stimulates RANKL-induced osteoclastogenesis of bone marrow-derived macrophages (BMMs) in vitro. We used microarrays to identified distinct classes of up-regulated genes in BMMs after GDF11 treatment. Mouse BMMs were treated with or without GDF11 for RNA extraction and and hybridization on Affymetrix microarrays

Project description:To identify the microRNAs that are involved in osteoclastogenesis, microRNA expression profiles in mouse bone marrow macrophages (BMMs) stimulated with RANKL (BMOc) were compared with that of control untreated BMMs. These results provide insights into the mechanisms to regulate osteoclastogenesis and bone resorption activities in osteoclasts by microRNA. BMMs were cultured with 20 ng/ml M-CSF in the presence or absence of 50 ng/ml RANKL for 24 hours. Cells were collected for total RNA isolation, and were subjected to microRNA array analysis.

Project description:Purpose: The goals of this study are to describe the DNA methylation profile during RANKL induced osteoclastogenesis. Methods: Primary bone marrow cells were isolated and treated with M-CSF (30ng/mL) to generate bone marrow macrophages (BMMs). BMMs were then used to generate preosteoclast (pOC) stimulated by M-CSF (30ng/mL) together with RANKL (100ng/mL) for 24 h and mature osteoclast (mOC) stimulated by M-CSF (30ng/mL) together with RANKL (100ng/mL) for 72 h or more. DNA methylation profiles of BMM, pOC and mOC were generated by deep sequencing, using Illumina NovaSeq 6000. Results: After acquiring of clean reads, we used Hisat2 for spliced mapping. We mapped about 40 million sequence reads per sample of the WGBS results. Saturation rate analysis was then performed evaluating the gene coverage rate along with read depth increase. The transcripts mapping to difference functional region of the genome was then analyzed. Circos software was used to map the consistency of samples with mouse genome on a chromosomal level. The quantification of transcript intensity was analyzed using RPKM (Reads Per Kb per Million reads). Conclusions: Our study represents the first high-throughput WGBS sequencing data of DNA methylation during osteoclastogenesis.

Project description:Purpose: Among the diverse cytokines involved in osteoclast differentiation, IL-3 has been shown to inhibit RANKL-induced osteoclastogenesis. However, the mechanism underlying IL-3-mediated inhibition of osteoclast differentiation is not fully understood. In the present study, we demonstrate that IL-3 activation of STAT5 inhibits RANKL-induced osteoclastogenesis through the induction of Id genes. Methods: To investigate the effect of STAT5 on osteoclast differentiation and IL-3-mediated inhibition of osteoclast differentiation, bone marrow derived macrophages isolated from STAT5 wild-type (Stat5fl/fl) or STAT5 cKO (STAT5;MX1-Cre) were differentiated to osteoclast in the presence of M-CSF and RANKL with or without IL-3; and bone marrow derived macrophges from STAT5 wild-type and STAT5 cKO were overexpressed with PMX-FIG (control) or STAT5A1*6 (constitutively active form of STAT5A) and differentiated to osteoclast. To analyze bone phenotype, femurs and tibiae of 16 week-old STAT5 wild-type and STAT5 cKO were subjected to micro CT analysis and histomorphometry, respectively. Results: Overexpression of STAT5 inhibited RANKL-induced osteoclastogenesis. However, RANKL did not regulate either expression or activation of STAT5 during osteoclast differentiation. STAT5 deficiency prevented IL-3-mediated inhibition of osteoclastogenesis, suggesting that STAT5 plays an important role in IL-3-mediated inhibition of osteoclast differentiation. In addition, IL-3-induced STAT5 activation upregulated expression of the Id1 and Id2 genes, which are negative regulators of osteoclastogenesis. Overexpression of ID1 or ID2 in STAT5-deficient cells reversed osteoclast development recovered from IL-3-mediated inhibition. Moreover, micro-computed tomography and histomorphometric analysis revealed that STAT5 conditional knockout mice showed reduced bone mass, with an increased number of osteoclasts. Furthermore, IL-3 inhibited RANKL-induced osteoclast differentiation less effectively in STAT5 conditional knockout mice than in wild-type mice in a RANKL injection model. Conclusion: Taken together, our results suggest that STAT5 is a key transcription factor for IL-3-mediated inhibition of RANKL-induced osteoclastogenesis through Id gene expression.

Project description:Bone marrow derived macrophages (BMM) from Notch2tm1.1Ecan, harboring a NOTCH2 gain-of-function mutation, and control mice were cultured with macrophage colony stimulating factor (M-CSF) and receptor activator of NF-kB ligand (RANKL). Bulk RNA-Seq revealed enhanced cell metabolism, aerobic respiration, and mitochondrial function, all associated with osteoclastogenesis, in Notch2tm1.1Ecan cells. Single cell RNA-Seq data of BMMs treated with M-CSF or M-CSF and RANKL for 3 days identified 11 well-defined cellular clusters. There was an increased number of cells expressing gene markers associated with the osteoclast and with related clusters in Notch2tm1.1Ecan than in control BMMs.

Project description:Clarification of the mechanisms underlying osteoclast differentiation enable us to understand the physiology of bone metabolism as well as the pathophysiology of bone diseases, such as osteoporosis. Recently, it has been reported that epigenetics can determine the cell fate and regulate cell type specific gene expression. However, little is known about epigenetics during osteoclastogenesis. To reveal a part of epigenetics, especially focused on chromatin dynamics, during early osteoclastogenesis and identify novel transcription factors involved in osteoclastogenesis, we investigated genome-wide analysis of open chromatin during receptor activator of nuclear factor-M-NM-:B ligand (RANKL)-induced osteoclastogenesis using DNase I hypersensitive sites sequencing (DNase-seq). DNase-seq was performed using the extracted nuclei obtained from RAW264 cells treated with or without RANKL for 24 hours, followed by several bioinformatic analyses. DNase I hypersensitive sites (DHSs) during RANKL-induced osteoclastogenesis were dynamically changed and accumulated in promoter regions, although the distributions of DHSs among cis-regulatory DNA regions were identical regardless of RANKL stimulation. Motif discoveries from DHSs successfully identified well-known osteoclastogenic transcription factors such as Jun, CREB1, FOS, ATF2 and ATF4, but also novel transcription factors for osteoclastogenesis such as Zscan10, Atf1 Nrf1 and Srebf2. siRNA knockdown of these identified novel transcription factors impaired osteoclastogenesis. Taken together, DNase-seq can be a useful tool for comprehension of epigenetics, especially chromatin dynamics during osteoclastogenesis and for identification of novel transcription factors involved in osteoclastogenesis. This study may reveal underlying mechanisms that determine cell-type specific differentiation of bone cells and may lead to investigate novel therapeutic targets for osteoporosis.
