Project description:EXPERIMENT: Microarray expression profiles derived from the human primary gingival epithelial cells 24.0h after exposure to heat inactivated P. gingivalis ANIMAL MODEL: NON EXPOSURE: Human primary gingival epithelial cells (at 3rd passage) were exposed to heat inactivated P. gingivalis (MOI:100) at 90% confluence. Two types of gingival epithelial cells were used. One with Normal cytokine inducer type (at least 2 fold IL-6/TNF-alpha/IL-1à when challenged with TLR2/4 agonists) and the other with diminished cytokine inducer type (no change in IL-6/TNF-alpha/IL-1à when challenged with TLR2/4 agonists). INTERVAL: NON. PLATFORM: microRNA expression profile in gingival epithelial cells - miRCURY LNA⢠microRNA Arrays (Exiqon). The RNA samples were subjected to microarray on 8/9/2007 Keywords = Human primary gingival epithelial cells Keywords = P. gingivalis Keywords = Periodontitis Keywords: Ordered The effect of heat inactivated P. gingivalison human primary gingival epithelial cells were assayed.

Project description:In order to explain the molecular mechanisms of capsaicin-induced proliferation of gingival epithelial cells (GECs), a microarray analysis was performed. Several cell proliferation related genes were significantly up-regulated. These data suggest that TRPV1 signaling in GEC may induce transcriptional upregulation of growth factors, which results in an increased proliferation rate. Simian virus 40 (SV40) T-antigen-immortalized human gingival epithelial cell line, epi4, were stimulated with 1 M-NM-<M capsaicin for 4 hours. Total RNA was isolated and subjected to gene expression analysis using Agilent whole human genome oligo microarray.
