Project description:During vertebrate craniofacial development, the oral epithelium begins as a simple and morphologically homogeneous tissue. It then gives rise to locally complex structures, including the developing teeth, salivary glands, and taste buds. While there is significant knowledge about the molecular mechanisms regulating the morphogenesis of these organs at later stages, how the epithelium is initially patterned and specified to generate diverse cell types and organs remains largely unknown. To elucidate the genetic programs that direct the formation of distinct oral epithelial populations, we conducted single cell RNA-sequencing using mandibular epithelia from embryonic day (E) 12.0 mouse embryos and whole mandibles from E9.5 mouse embryos. The goal of this study is therefore to generate a detailed transcriptional atlas of the developing mandibular epithelium.

Project description:During craniofacial development, the oral epithelium begins as a morphologically homogeneous tissue that gives rise to locally complex structures, including the teeth, salivary glands and taste buds. How the epithelium is initially patterned and specified to generate diverse cell types remains largely unknown. To elucidate the genetic programs that direct the formation of distinct oral epithelial populations, we mapped the transcriptional landscape of embryonic day 12 mouse mandibular epithelia at single cell resolution. Our analysis identified key transcription factors and gene regulatory networks that define different epithelial cell types. By examining the spatiotemporal patterning process along the oral-aboral axis, our results propose a model in which the dental field is progressively confined to its position by the formation of the aboral epithelium anteriorly and the non-dental oral epithelium posteriorly. Using our data, we also identified Ntrk2 as a proliferation driver in the forming incisor, contributing to its invagination. Together, our results provide a detailed transcriptional atlas of the embryonic mandibular epithelium, and unveil new genetic markers and regulators that are present during the specification of various oral epithelial structures.

Project description:Transcriptional profiling was utilized to define the biological pathways of gingival epithelial cells modulated by co-culture with the oral pathogenic Porphyromonas gingivalis and Aggregatibacter (formerly actinobacillus) actinomycetemcomitans. We used microarrays to detail the global programme of gene expression underlying infection and identified distinct classes of up- and down-regulated genes during this process. Experiment Overall Design: Gingival epithelial HIGK cells were sham infected (CTRL) and infected with either the oral pathogenic P. gingivalis (Pg) or A. actinomycetemcomitans (Aa). These samples were hybridized to Affymetrix microarrays. Understanding how host cells have adapted to pathogens, and how barrier cells respond to limit their impact, provides a mechanistic biological basis of microbial disease in the mixed bacterial-human ecosystem of the oral cavity.

Project description:Transcriptional profiling was utilized to define the biological pathways of gingival epithelial cells modulated by co-culture with the oral commensal S. gordonii and the opportunistic commensal F. nucleatum. We used microarrays to detail the global programme of gene expression underlying infection and identified distinct classes of up- and down-regulated genes during this process. Experiment Overall Design: Gingival epithelial HIGK cells were sham infected (CTRL) and infected with either the oral commensal S. gordonii (Sg) or the opportunistic commensal F. nucleatum (Fn). These samples were hybridized to Affymetrix microarrays.

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. 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:Thiele2013 - Oral mucosa squamous epithelial cells
The model of oral mucosa squamous epithelial cells metabolism is derived from the community-driven global reconstruction of human metabolism (version 2.02, MODEL1109130000
).
This model is described in the article:
A community-driven global reconstruction of human metabolism.
Thiele I, et al

Nature Biotechnology
Abstract:
Multiple models of human metabolism have been reconstructed, but each represents only a subset of our knowledge. Here we describe Recon 2, a community-driven,
consensus 'metabolic reconstruction', which is the most comprehensive representation of human metabolism that is applicable to computational modeling. Compared
with its predecessors, the reconstruction has improved topological and functional features, including ~2x more reactions and ~1.7x more unique metabolites. Using
Recon 2 we predicted changes in metabolite biomarkers for 49 inborn errors of metabolism with 77% accuracy when compared to experimental data. Mapping metabolomic
data and drug information onto Recon 2 demonstrates its potential for integrating and analyzing diverse data types. Using protein expression data, we automatically
generated a compendium of 65 cell type-specific models, providing a basis for manual curation or investigation of cell-specific metabolic properties. Recon 2 will
facilitate many future biomedical studies and is freely available at http://humanmetabolism.org/.

Project description:Keratinocytes are the major constituent of epithelial cells at mucosal surfaces and skin, which cover organs, internal cavities and the body. Traditionally, keratinocytes have been considered as an inert component of the multilayered epithelium to protect the subepithelial compartments from the pathogenic microorganisms, toxic stimuli and physical trauma. However, accumulated researches of the airway, gastrointestinal tract and skin have demonstrated that keratinocytes function in the development of the immune system, promotion of pathologic inflammation and even impose diverse decisions on immune cells. We used microarrays to detail the global gene expression of oral keratinocyte during oral adaptive immune response. Oral keratinocyte were collected at three time points (control, 48h and 96h) in oral adaptive immune response for RNA extraction and hybridization on Affymetrix microarrays

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.
