The effect of PTEN inhibitor on Periodontal ligament cells

Project description:Objective: Phosphatase and Tensin Homolog (PTEN) act as a negative regulator of the phosphatidylinositol-3-kinase (PI3k)/Akt pathway, which is involved in cell growth, cell proliferation, differentiation, and survival signaling. This study aimed to investigate the effects of VO-OHpic, a PTEN inhibitor, on periodontal ligament stem cells (PDLSCs).

Differentially expressed long noncoding RNA expression between periodontal ligament stem cells from healthy periodontal tissue and periodontal ligament stem cells from inflammatory periodontal tissue.

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).

Effect of FDC-SP on Gene Expression of Human Periodontal Ligament Cells

Project description:Previous research has reported that FDC-SP had similar molecular properties to statherin, a protein exists in saliva which plays important roles in preventing Ca precipitation. Further biomolecular study has suggested that the expression of FDC-SP may be associated with periodontal ligament (PDL) phenotype expression. Therefore, we hypothesized that FDC-SP may play specific roles in the inhibition of calcium precipitation during periodontal regeneration, as well as affect phenotype expression of periodontal ligament cells (PDLCs) during the differentiation process. To investigate this, we applied microarray technology to identify gene expression changes in hPDLCs transfected with FDC-SP and then clustered them according to their biological functions. We firstly established a recombinant lentiviral vector containing FDC-SP and obtained safe and efficient FDC-SP overexpression in human periodontal ligament cells (hPDLCs). After that, we applied Agilent Whole Human Genome Oligo Microarray (4M-CM-^W44K) to identify differentially expressed genes between empty vector-transfected hPDLCs and FDC-SP -transfected ones and then clustered them according to their biological functions. 3 independent experiments were performed and the empty vector-transfected hPDLCs were used as control.

scRNA-seq analysis of murine periodontal ligament

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.

Recombinant irisin enhances the differentiation, remodeling potential, and the mechanical properties of 3D-cultured human periodontal ligament cells

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.
