Project description:To identify the active enhancers and promoters in human oral epithelial cell line, we performed H3K27Ac ChIP-seq for HIOEC cell line.
Project description:A majority of individuals infected with human immunodeficiency virus (HIV) have inadequate access to antiretroviral therapy and ultimately develop debilitating oral infections that often correlate with disease progression. Our study evaluates the impact of chronic exposure to the pro-inflammatory cytokine, interferon gamma, on the growth and barrier functions of the oral epithelium. Microarrays were used to characterize changes in gene expression in the TR146 oral epithelial cell line that occur in response to constitutive exposure to interferon gamma in the growth media.

Microarrays were used to characterize changes in gene expression in the TR146 oral epithelial cell line that occur in response to constitutive exposure to interferon gamma in the growth media. TR146 epithelial cells were grown to confluence in two 6-well culture plates in the presence (plate 1) or absence (plate 2) of interferon gamma and used for RNA extraction and hybridization on Affymetrix microarrays.
Project description:To compare the features of nucleosome-free regions between human oral epithelial cells and zebrafish periderm, we performed ATAC-seq using immortalized human oral epithelial cells, HIOEC, with human embry palatal mesenchyme cells, HEPM, as control.
Project description:Microarrays were used to examine gene expression differences between human head and neck squamous cell carcinoma cell lines (FaDu, UTSCC8, UTSCC42a) grown in culture in comparison to a normal oral epithelial cell line. Gene expression data was integrated with global protein expression of head and neck squamous cell carcinoma cell lines and conditioned media to identify secreted protein markers up-regulated at the mRNA level in cancer cells versus the normal cell line. Total RNA obtained from head and neck squamous cell carcinoma cell lines and a normal oral epithelial cell line
Project description:The mechanisms through which oral commensal bacteria mitigates uncontrolled inflammatory responses in the oral mucosa remain unknown. Here we evaluated the ability of S. gordonii to stimulate the expression of miRNAs in oral epithelial cells with potential to target chemokine expression. The human oral epithelial cell line (OKF6) was exposed to different MOIs of S. gordonii for 24h and expression analysis of miRNAs performed using the Affymetrix platform.

Project description:The use of in vitro cell culture systems has been of central importance for research of physiology, pharmacology, and toxicology, and functions at the cellular and molecular levels. We have developed an immortalized oral epithelial cell line ROE2 from fetal transgenic rats harboring temperature-sensitive simian virus 40 large T-antigen. Here, to identify genes involved in ROE2 cell differentiation, global-scale gene expression analysis was carried out using a GeneChipM-BM-. system. ROE2 cells, an immortalized oral epithelial cell line from transgenic rats harboring temperature-sensitive simian virus 40 large T-antigen, were cultured for 0, 3, 6 and 9 days at 37M-KM-^ZC. Total RNA samples were prepared from the cells, and quality of the RNA was analyzed using a Bioanalyzer 2100. Gene expression was monitored by an Affymetrix GeneChipM-BM-. system with a Rat Genome 230 2.0 array. Sample preparation for array hybridization was carried out as described in the manufacturer's instructions.
