Project description:Purpose : This study was performed to investigate the changes in gene expression in periodontal ligament (PDL) cells following mechanical stimulus through RNA sequencing. Method : Premolars extracted for orthodontic treatment were used. To stimulate the PDL cells, an orthodontic force of 100× g was applied to the premolar (experimental group; n = 11), whereas the tooth on the other side was left untreated (control group; n = 11). After the PDL cells were isolated from the extracted teeth, gene set enrichment analysis (GSEA), differentially expressed gene (DEG) analysis, and real-time PCR were performed to compare the two groups. Result : GSEA demonstrated that gene sets related to the cell cycle pathway were upregulated in PDL. Thirteen upregulated and twenty downregulated genes were found through DEG analysis. Real-time PCR results confirmed that five upregulated genes (CC2D1B, CPNE3, OPHN1, TANGO2, and UAP-1) and six downregulated genes (MYOM2, PPM1F, PCDP1, ATP2A1, GPR171, and RP1-34H18.1-1) were consistent with RNA sequencing results. Conclusion : Two upregulated genes, CPNE3 and OPHN1, and one downregulated gene, PPM1F, play an important role in PDL regeneration in humans when orthodontic force is applied.

Project description:Mechanical force has been shown to regulate periodontal ligament cells (PDLs) behaviors. However, different force types lead to distinct PDLs’ responses. Here, the differential gene expression profiling of PDLs subjected to static and intermittent compressive forces was examined using RNA sequencing technique. Results demonstrated that the static and intermittent compressive force treated PDLs exhibited the differential regulation genes. KEGG pathway enrichment analysis revealed that focal adhesion and transforming growth factor beta signaling pathway were commonly upregulated while calcium signaling pathway was downregulated in both static and intermittent compressive force-treated PDLs. Interestingly, Wnt signaling pathway was upregulated only in the PDLs that subjected to the intermittent compressive force.

Project description:Human periodontal ligament (HPDL) is continuously exposed to mechanical stress in vivo. In this study, in utilizing DNA chips, we analyzed the influences of mechanical stress on the gene expression profile of HPDL cells in vitro. HPDL cells were obtained from extracted first premolars of individuals undergoing tooth extraction for orthodontic treatment. Then, HPDL cells were applied to a stretch apparatus. They were constantly stretched and relaxed at 0.5 Hz for 48hr with 110ï¼ force elongation. After the application of the cyclic tension force, total RNA was extracted. Then, in utilizing the DNA chips (Human Oligo 30K DNA Chip containing almost all human genes in the genome). We analyzed the differences of gene expression between the stretched and the non-stretched control HPDL cells The DNA chip analysis identified 17 up-regulated genes that showed at least 2-fold difference in their relative intensities between the stretched and the control. This result included the genes for the glutamate receptor binding protein: HOMER1, for the growth factor receptor: CNTFR, for the ECM remodeling protein: MMP15, for the protein interacting with calcineurin A: DSCR1, for the cytoskeletal protein: LRRFIP1, for the glutamate receptor: GRIN3A and some novel genes. On the basis of these data, we suggest that mechanical stress, in other words in vivo occlusal force, may affect the functions of HPDL cells Gene expression profiles were constructed using Human Oligo DNA Chip 30K (Hitachi software engineering) in human periodontal ligament cells (The 48-h stretched and the 48-h non-stretched, control).

Project description:The long non-coding RNA landscape of periodontal ligament stem cells subjected to compressive force
| PRJNA480245 | ENA
Project description:Periodontitis can impair the osteogenic differentiation of human periodontal mesenchymal stem cells, but the underlying molecular mechanisms are still poorly understood. Long noncoding RNAs (lncRNAs) have been demonstrated to play significant roles under both physiologic and pathological conditions. We performed comprehensive lncRNAs profiling by lncRNA microarray to identify differentially expressed long noncoding RNA expression between Periodontal ligament stem cells from healthy Periodontal tissue and periodontal ligament stem cells from inflammatory periodontal tissue. Our analysis identified 233 lncRNAs and 423 mRNAs that were differently expressed (fold change >2.0, p-value < 0.05) between the two groups of cells. The GO analysis revealed that the significantly down-regulated biological processes included multicellular organismal process, developmental process and multicellular organismal development and the significantly up-regulated biological processes included cellular process, biological regulation and response to stimulus in periodontal ligament stem cells from inflammatory periodontal tissue. The Pathway analysis revealed that the differentially expressed mRNAs may involved in Focal adhesion, ECM-receptor interaction, Bacterial invasion of epithelial cells, Long-term depression, Circadian entrainment and HIF-1 signaling pathway. Two-condition experiment, periodontal ligament stem cells from healthy periodontal tissue (hPDLSCs) vs. periodontal ligament stem cells from inflammatory periodontal tissue (pPDLSCs), Biological replicates: 3 control replicates (hPDLSCs), 3 testing replicates (pPDLSCs).

Project description:This study aimed to investigate the microRNA expression profile of mechnically strained human periodontal ligament-derived stem cells, and SurePrint G3 Human v16 miRNA Array (Agilent) was employed as a screening platform. We discovered 39 differentially expressed microRNAs between the stretched and the static control group. Human periodontal ligament-derived stem cells were cultured on elastic silicone membranes and either subjected to a dynamic mechanical strain protocol (2hr, 5% elongation, 0.5Hz) or left undisturbed. Total RNA was collected and extracted by TRIzol. RNA samples with 28S/18S ratios in the range of 1.4 to 1.8 were used for microRNA microarray analysis using the Agilent SurePrint G3 Human v16 miRNA Array Kit. The samples in each group were triplicated.
