Project description:Irisin is recognized as a myokine produced by muscles, regulating metabolism and energy homeostasis, however, it may play a role in many other biological functions. Little is known about its effect on periodontal ligament cells. We employed Affymetrix to profile mRNA expression patterns between 3D human periodontal ligament cell spheroids treated with and without irisin. The mRNA expression profiling identified approximately 1000 mRNAs to be differentially expressed between the two groups, which suggests that irisin is involved in gene regulation in human periodontal ligament cells.

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: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:Maresin-1 (MaR1) and Resolvin E1 (RvE1) are specialized pro-resolving lipid mediators (SPMs) that regulate inflammatory processes. We have previously demonstrated the hard and soft tissue regenerative capacity of RvE1 in an in vivo model of periodontal disease characterized by inflammatory tissue destruction. Regeneration of periodontal tissues requires a well-orchestrated processes mediated by periodontal ligament stem-cells. However, limited data are available on how SPMs can regulate the regenerative properties of human periodontal ligament stem cells (hPDLSCs) under inflammatory conditions. Thus, we measured the impact of MaR1 and RvE1 in an in vitro model of hPDLSCs after stimulation with IL-1β and TNF-α by evaluating pluripotency, migration, proliferation, cell death, periodontal ligament markers (α-smooth muscle actin, tenomodulin, and periostin), cementum-osteogenic differentiation and phosphoproteomic perturbations. The data showed that the inflammatory milieu suppresses pluripotency, proliferation and migration of hPDLSCs; MaR1 and RvE1 both restored regenerative capacity by increasing hPDLSC proliferation, accelerating wound healing/migration, and upregulating periodontal ligament markers and cementum-osteogenic differentiation. Protein phosphorylation perturbations were associated with the SPM-induced regenerative capacity of hPDLSCs. Together, these results demonstrate that MaR1 and RvE1 restore or improve the regenerative properties of highly specialized stem cells when inflammation is present and offer opportunities for direct pharmacologic treatment of lost tissue integrity.

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.

Project description:Periodontal tissue supports teeth in the alveolar bone socket via fibrous attachment of the periodontal ligament (PDL). The PDL contains many stromal cell types, including osteoblasts, cementoblasts, periodontal fibroblasts, and stem/progenitor cells. However, the characteristics and lineage hierarchy of each cell type remain poorly defined. Here we present a single-cell atlas of PDL, highlighting diverse cell populations in PDL.
