Project description:Expressions of mRNA in osteoclast precursors treated with RANKL and M-CSF for 0, 24, and 72 h. We used DNA microarray to analyze the changes in mRNA expressions during osteoclastogegesis. Experiment Overall Design: Osteoclast precursors were induced from mouse bone marrow cells by M-CSF for 3 days and treated with RANKL. WE extracted total RNA and analyzed by DNA microarray.

Project description:Comparison of gene expression of the osteoclast precursor myeloid blast seeded on plastic and on bone, primed with M-CSF for 4 days and culture with M-CSF and RANKL for 1 day. Osteoclasts and macrophages share progenitors that must receive decisive lineage signals driving them into their respective differentiation routes. Macrophage colony stimulation factor M-CSF is a common factor; bone is likely the stimulus for osteoclast differentiation. To elucidate the effect of both, shared mouse bone marrow precursor myeloid blast was pre-cultured with M-CSF on plastic and on bone. M-CSF priming prior to stimulation with M-CSF and osteoclast differentiation factor RANKL resulted in a complete loss of osteoclastogenic potential without bone. This coincided with a steeply decreased expression of osteoclast genes TRACP and DC-STAMP, but an increased expression of the macrophage markers F4/80 and CD11b. Compellingly, M-CSF priming on bone accelerated the osteoclastogenic potential: M-CSF primed cells that had received only one day M-CSF and RANKL and were grown on bone already expressed an array of genes that are associated with osteoclast differentiation and these cells differentiated into osteoclasts within 2 days. This implies that adhesion to bone dictates the fate of osteoclast precursors. Common macrophage-osteoclast precursors may become insensitive to differentiate into osteoclasts and regain osteoclastogenesis when bound to bone or when in the vicinity of bone.

Project description:Osteoclast (OC) differentiation undergoes a two-step process: commitment of hematopoietic progenitor cells to tartrate-resistant acid phosphatase (TRAcP) positive OC precursors (OCPs), and fusion of OCPs into multinucleated OCs. In order to identify transcriptional profiles of genes in the transitional phase between OC commitment and fusion in OCG, AffymetrixM-BM-. Mouse Gene 1.0 ST arrays were performed on total RNA extracted from mouse (SV129/BL6 ) monocytes and pre-osteoclasts (pre-OCs), primed with macrophage colony-stimulated factor (M-CSF) or M-CSF and soluble recombinant receptor activator of NF-M-PM-:B ligand (sRANKL), respectively. The analysis identified 656 RANKL-up or down-regulated in the early stage of osteoclastogenesis. Monocytes isolated from mouse bone marrow were stimulated with M-CSF and soluble RANKL (m + r), or M-CSF alone (m).

Project description:Osteoclasts are multinucleated cells specialized in degrading the mineralized bone matrix. Osteoclast differentiation and function are tightly regulated, to prevent excessive or insufficient bone resorption. Several control mechanisms participate in modulating osteoclastogenesis, and an increasing number of reports describe the role of microRNAs (miRNAs) in this process. Disrupting the expression of specific miRNAs can result in alterations of osteoclast formation and bone homeostasis. We and others have previously characterized 9 miRNAs whose levels change during osteoclast differentiation, and identified some of the target genes that mediate their function. However, little is known about changes in the miRNA expression profile during osteoclastogenesis. In this study, we isolated a murine primary bone marrow population enriched for osteoclast precursors, and used the Agilent microarray platform to analyze the expression of mature miRNAs after 1, 3, and 5 days of RANKL-driven differentiation. 93 miRNAs showed greater than 2 fold-change during these early, middle, and late stages of osteoclastogenesis. Many of these miRNAs were detected for the first time in osteoclasts, and we validated the expression of selected miRNAs by quantitative RT-PCR. We identified clusters of differentially expressed miRNAs, and performed computational analyses to predict functional pathways that may be regulated by these miRNAs. Several miRNAs were predicted to regulate genes involved in cytoskeletal remodeling, a crucial mechanism for the migration of osteoclast precursors, their maturation, and bone resorbing activity. Our results suggest that clusters of miRNAs differentially expressed during the course of osteoclastogenesis converge on the regulation of several key functional pathways. Overall, this study identified miRNAs expressed during early, middle and late osteoclastogenesis, contributing to understanding the molecular mechanisms regulating this complex differentiation process. Mouse primary bone marrow cultures were enriched for osteoclast precursors by depletion of B220/CD45R+ and CD3+ cells (B and T lymphocytes, respectively). Cells were differentiated with M-CSF and RANKL, and miRNA expression was analyzed at days 1, 3, and 5. Four biological replicates for each time point were used.

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: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.
