Project description:Gprc5a is a lung tumor suppressor gene. Gprc5a-knockout (ko) mice can develop spontaneous lung cancer and Gprc5a-ko mouse model is relevant to human lung cancer. Thus, exploration of the mechanisms underlying lung tumorigenesis in Gprc5a-ko mice would be very helpful for revealing those in human lung cancer. We used microarrays to detail the global gene expression profile that underlies oncogenesis by Gprc5a-knockout gene deletion in mouse tracheal epithelial cells. Wild type and gene-knockout mouse tracheal epithelial cells that were divided into two groups were used for RNA extraction.

Project description:Analysis of the role of Hipk2 in regulating gene expression in medullary thymic epithelial cells. The whole genome gene signatures of purified mTEC subsets (CD80 low, CD80 high) from TEC-specific Hipk2 knockout mice were compared to mating wildtype control mice (floxed, Cre-). Results provide the up- or down-regulated genes, affected by the Hipk2 gene knockout. Total RNA obtained from isolated CD80 low and CD80 high mTECs of TEC-specific Hipk2 knockout mice compared to control mice mTEC subsets

Project description:Nine cigarette smoke condensates (CSCs) were produced under a standard ISO smoking machine regimen and one was produced by a more intense smoking machine regimen. These CSCs were used to treat primary normal human bronchial epithelial cells for 18 hours. Experiment Overall Design: Primary human bronchial/tracheal epithelial cells were grown in culture and treated with 10 different sources of cigarette smoke condensates.

Project description:The epithelial layer lining the airways has a central role in maintaining lung health, particularly serving as a barrier to prevent infection and delivery of harmful particles, which are cleared from the lung on the mucociliary escalator driven by the epithelium. Robust methods to culture primary airway epithelial cells were developed several decades ago and these cells provide the model of choice to investigate many diseases of the human lung. However, to date the molecular signature of cells from different regions of the airway epithelium has not been well characterized. Here we examine primary cells derived from human tracheal and bronchial tissues and perform genome-wide analysis of their active regulatory elements and gene expression profiles. We also compare cells from healthy and diseased (cystic fibrosis) donor lung tissue. Our data reveal an airway cell signature that is divergent from other epithelial cell types and from immortalized or transformed airway epithelial cell lines. The differences between tracheal and bronchial cells are clearly evident as are common regulatory features between the cell types of two different origins. Only minor variation is seen between cells from healthy or CF bronchial cells. These data are a valuable resource for functional genomics analysis of airway epithelial tissues in human health and disease.

Project description:The signaling crosstalk between the tracheal mesenchyme and epithelium has not been researched extensively leaving a substantial gap of knowledge in the mechanisms dictating embryonic development of the proximal airways by the adjacent mesenchyme. Recently, we have reported that embryos lacking mesenchymal expression of Sox9 did not develop tracheal cartilage rings and showed aberrant differentiation of the tracheal epithelium. Herein, we propose that tracheal cartilage provides local inductive signals responsible for the proper differentiation, metabolism, and inflammatory status regulation of the tracheal epithelium. The tracheal epithelium of mesenchyme-specific Sox9D/D mutants showed altered mRNA expression of various epithelial markers such as Pb1fa1, Sftpb, Scgb1a1, and Tff-1. In vitro tracheal epithelial cell cultures confirmed that tracheal chondrocytes secrete factors that inhibit club cell differentiation. Whole gene expression profiling and ingenuity pathway analysis showed that the TNF-a, IFN-g and TGF-b signaling pathways were significantly altered in the Sox9 mutant trachea. Tnf-a and Ifn-g interfered with the differentiation of tracheal epithelial progenitor cells into mature epithelial cell types in vitro. Meanwhile, mesenchymal knockout of Tgf-b1 in vivo resulted in altered differentiation of the tracheal epithelium. Finally, mitochondrial enzymes involved in fat and glycogen metabolism Cox8b and Cox7a1 were strongly up-regulated in the Sox9 mutant trachea, with consequently increased number and size of glycogen storage vacuoles. Our results support an a role for tracheal cartilage in the modulation of the differentiation and metabolism, and the expression of inflammatory related genes in the tracheal epithelium by feeding into the TNF-a, IFN-g and TGF-b signaling pathways.

Project description:We performed global scale microarray analysis to identify detailed mechanisms by which nonpermissive temperature induces cell growth arrest and differentiation in tracheal epithelial RTEC11 cells harboring temperature-sensitive simian virus 40 large T-antigen by using an Affymetrix GeneChip system. Tracheal epithelial RTEC11 cells used in this study were derived from transgenic rats harboring a temperature-sensitive simian virus 40 large T-antigen. Although the cells grew continuously at the permissive temperature, the nonpermissive temperature led to cell growth arrest and differentiation. Experiment Overall Design: A rat conditionally immortalized tracheal epithelial cell line, RTEC11, derived from transgenic rats harboring a temperature-sensitive simian virus 40 large T-antigen was used. RTEC11 cells were cultured at permissive (33°C) or nonpermissive (39°C) temperature for 3 days.

Project description:Mouse tracheal epithelial cells were cultured at air-liquid interface (ALI), RNA was harvested at days 0, 2, and 7 post-ALI, and hybridized to two-channel MEEBO arrays. The experiment was designed to allow investigators to identify genes differentially expressed during airway epithelial cell differentiation and development, including ciliogenesis.

Project description:Oligonucleotide microarrays were used to establish a profile for gene expression in wild-type airway epithelial cells after paramyxoviral infection. Analysis was performed on mRNA isolated from SeV-infected primary-culture mouse tracheal epithelial cells that were maintained under physiologic conditions (air-liquid interface). Experiment Overall Design: Primary-culture mouse tracheal epithelial cells (mTECs) were established on Transwell membranes using air-liquid interface (ALI) conditions. Sendai virus (SeV), strain 52, was obtained from American Type Culture Collection and stored at -70°C. Cultures were inoculated with SeV or an equivalent amount of UV-inactivated SeV (SeV-UV) in the apical compartment for 1 h at 37 °C. Air-liquid-interface conditions were re-established by washing the membrane with PBS. Each culture well was subjected to one of two treatments (SeV, or UV-SeV) for 1 day. N = 4 SeV wells, N = 6 UV-SeV wells, with each well independently analyzed by microarray. No technical replicates were performed, but arrays were evaluated for quality control using the SimpleAffy package (Miller CJ, 2004) in Bioconductor 2.0.
