Project description:Cementum protein 1 (CEMP1) is involved in cell adhesion, cell differentiation, regulates the mineralization processes during cementogenesis, and selects progenitor cells from periodontal ligament. To determine the gene expression profiling induced by CEMP1 overexpression by non-osteogenic cells such as human gingival fibroblasts we performed microarrays (Human Gene 1.0 ST, Affymetrix) to identify differentially expressed transcripts (ED) between human gingival fibroblasts (HGF) and those that overexpress CEMP1 (HGF/CEMP1).

HGF cells overexpressing CEMP1 and controls were harvested at 3, 7 and 14 days after transfection of CEMP1, three biological replicates were analyzed for each time point and condition for a total of 18 microarrays.
Project description:To understand the role of areca nut and TGF-β induced gene expression changes in fibroblasts and its contibution in the manifestation of Oral submucous fibrosis, we studied gene expression profile in primary human gingival fibroblast (hGF) cells following treatment with areca nut, TGF-β and both together.
Project description:Bulk RNA sequencing was used to characterize transcriptional changes associated with the dysfunctional metabolic state in murine gingival fibroblasts (mGF). The mGF were treated with BSA control, palmitate, IL-1β, or palmitate plus IL-1β. Gene ontology analysis demonstrated enrichment of pathways related to innate immune activation, oxidative stress, mitochondrial dysfunction, ER stress, and purine metabolism. Palmitate disrupts the Cd73-adenosine axis while promoting mitochondrial dysfunction, oxidative stress, and Perk-mediated ER stress in gingival fibroblasts. Adenosine signaling protects against lipotoxic-induced ER stress, highlighting the relevance of the Cd73-adenosine pathway for metabolic and inflammatory diseases.
Project description:This study sought to provide a novel ex vivo model for analyzing healing kinetics and gene expression of primary human gingival fibroblasts (hGF) within collagen scaffolds. Sponge type and gel type scaffolds with and without platelet-derived growth factor-BB (PDGF) were assessed in an hGF containing matrix.

Sponge type and gel type scaffolds with and without platelet-derived growth factor-BB (PDGF) were assessed in an hGF containing matrix. Four samples were analyzed; gel w/ and w/o PDGF and scaffold w/ and w/o PDGF
Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.

Control Vs Areca nut 5 µg/ml water extract (5H) (2), Contro Vs TGF-β (2), Control Vs Areca nut (5 µg/ml) and TGF-β (5 ng/ml) (5H+T) (2). (2)- Biological duplicates.
Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression.
