Project description:The miRNAs play important roles in regulating gene expression at post-transcriptional level through fine-tuning of protein-encoding gene expression, and are involved in regulating important biological processes in different cells and tissue types, including osteoblast differentiation. Canonical Wnt signaling is also known to play pleiotropic roles in regulating cell differentiation during mammalian osteogenesis, although the role of miRNAs is not established for Wnt signaling in osteoblast differentiation. Here we examined the role of candidate miRNAs expressed differentially after Wnt3a expression during osteoblast differentiation. Overexpression of the Wnt3a gene resulted in increased transcription of the ALP gene, but in decreased transcription of the Runx2, Col1a and OCN genes in osteoblastic MC3T3-E1 cells. Analysis of miRNA expression profile showed that 14 miRNAs were up-regulated and 21 miRNAs were down-regulated after Wnt3a overexpression in MC3T3-E1 cells. TGF-beta3 is presumed to be a candidate target gene of one of the down-regulated miRNAs with database search. Transfection of the miRNA mimic into MC3T3-E1 cells significantly inhibited the TGF-beta3 mRNA level and resultant protein expression, although overexpression of the Wnt3a gene could reverse the effect of the miRNA, resulting in the increased TGF-beta3 mRNA and protein levels. These results suggest that the miRNA is involved in osteoblast differentiation as a critical regulatory factor, mediating crosstalk between Wnt3a signaling pathway and TGF-beta3 signaling pathway.

Project description:Bone is the main site of metastasis from prostate cancer, it is important to investigated miRNAs and mRNAs of bone metastases from prostate cancer. Considering that bone is in an appropriate mechanical environment in physiological state, in this study, the miRNA, mRNA, lncRNA profiles of mechanically strained osteoblasts treated with conditioned medium of PC-3 prostate cancer cells were studied. MC3T3-E1 osteoblastic cells were treated with conditioned medium of PC-3 prostate cancer cells, at the same time stimulated with mechanical tensile strain of 2,500 microstrain (με) at 0.5 Hz, the osteoblastic differentiation of the MC3T3-E1 cells were assayed

Project description:Transcriptional profiling of MC3T3-E1 osteoblasts that were flow cytometry-separated from cocultures with control or Jagged1-overexpressing tumor cells and treated with either DMSO control or 1μM MRK-003 (gamma-secretase inhibitor). One cell line (MC3T3-E1) cells: four different experimental conditions: cultured with (1) control tumor cells + DMSO; (2) Jagged1-overexpressing tumor cells + DMSO; (3) control tumor cells + MRK-003; (4) Jagged1-overexpressing tumor cells + MRK-003. Each experiment has two biological replicates. Total, 8 samples.

Project description:In order to define the underlying mechanism of fluoride resistance in mammals and provide a theoretical basis for fluorosis treatment, high-throughput sequencing was applied to map the genetic changes of fluoride-resistant mouse osteoblasts. Fluoride-tolerant MC3T3-E1 cells were developed by gradient fluoride exposure. The differentially expressed genes of fluorine-resistant MC3T3-E1 cells were identified by high-throughput sequencing. High-throughput RNA sequencing identified 2702 differentially expressed genes (DEGs) showed more than 2-fold difference in 30ppm FR MC3T3-E1 cells, of which 17 DEGs were associated with ferroptosis.

Project description:To investigate the molecular mechanism underlying osteogenic and angiogenic differentiation induced by the De-HA scaffold, we conducted an in-depth gene microarray analysis on day 3 of MC3T3-E1 culture. We found that De-HA could enhance the transcription of osteogenic and angiogenic genes by activating FAK and downstream MAPK/ERK signaling to induce MC3T3-E1 differentiation. More importantly, our findings indicated that EGFR, a kind of transmembrane glycoprotein, played a key role in the osteogenic differentiation of MC3T3-E1, suggesting that the activation of the FAK/MAPK/ERK signaling cascade might be driven by EGFR.

Project description:Osteoblasts are responsive to shear stress. We investigated the effect of of laminar fluid flow (LFF) on osteoblast-like MC3T3-E1 cells at two timepoints. We used microarray analysis to detail the global gene expression of MC3T3-E1 cells in response to 1 hour of laminar fluid flow directly and 4 hours after treatment.

Project description:Exosomes are nanoscale extracellular vesicles. Several studies have shown that exosomes participate in intercellular communication and play a key role in osseointegration. However, it is unclear whether exosomes and their contents participate in the communication between the immune and skeletal systems in the process of osseointegration. In this study, we obtained smooth titanium disks by polishing and micro-/nano-texture hierarchical topography titanium disks by sandblasted large-grit acid-etched (SLA) technology combined with alkali thermal reaction. After stimulating rat RAW264.7 cells with these two kinds of titanium disks, we co-cultured the MC3T3-E1 cells and the RAW264.7 cells, obtained and identified the exosomes derived from RAW264.7 cells, and studied the effect of the osteoimmune microenvironment and the exosomes on the osseointegration of rat MC3T3-E1 cells. Cell counting kit-8 (CCK-8), real time quantitative PCR, western blotting, alizarin red staining, and quantitative and confocal fluorescence microscopy were used to study the effects of exosomes on MC3T3-E1 cells; RNA sequencing and correlation analysis were performed. We found that the osteoimmune microenvironment could promote the osseointegration of MC3T3-E1 cells. We successfully isolated exosomes and found that RAW264.7 cell-derived exosomes can promote osteogenic differentiation and mineralization of MC3T3-E1 cells. Through RNA sequencing and gene analysis, we found differentially expressed microRNAs that targeted the signal pathways that may be related, such as mTOR, AMPK, Wnt, etc, and thus provide a reference for the mechanism of osteoimmunue regulation of implant osseointegration. The study further elucidated the mechanism of implant osseointegration and provided new insights into the effect of exosomes on implant osseointegration, and provided reference for clinical improvement of implant osseointegration and implant success rate.
