Project description:To investigate the biochemical and genetic alterations that occur in response to cigarette smoke exposure among airway epithelial cells from different sites in the lungs, we performed microarray-based analysis using small airway epithelial cells (SAEC) and normal human bronchial epithelial cells (NHBE) following 24 h of cigarette smoke extract (CSE). In microarray-based analysis, the small airway showed higher susceptibility to CS compared to the large airway, such as enhanced expression of inflammatory-related pathways including the TNF signaling pathway. Among the TNF-related genes, PTGS2, also known as COX-2, showed the greatest difference in expression levels, with higher CSE-induced increments of both mRNA and protein expression in SAEC compared to NHBE.

Project description:A variety of airborne pathogens can induce inflammatory responses in airway epithelial cells, which is a crucial component of host defence. However, excessive inflammatory responses and chronic inflammation also contribute to different diseases in the respiratory system. We hypothesized that the activation of protein kinase C (PKC) is one of the essential mechanisms of inflammatory responses in airway epithelial cells. In the present study, we stimulated human bronchial lung epithelial (BEAS-2B) cells with phorbol ester Phorbol 12, 13-dibutyrate (PDBu), and examined gene expression profile with microarray analysis. Bioinformatics suggested that PKC activation induced dramatic changes in gene expression related to multiple cellular functions. The top two functional networks of genes were centered on NFM-NM-:B and TNF-M-NM-1, which are two commonly known pathways for cell death and inflammation. Subsequent tests confirmed the decrease in cell viability and increase in the production of various cytokines. Interestingly, each of the increased cytokines was differentially regulated at mRNA and/or protein levels by different sub-class of PKC isozymes. We conclude that many pathogen-induced cell death and cytokine production in airway epithelial cells may be mediated through PKC related signaling pathways. These findings suggest that PKCs can be new targets for treatments of lung diseases. Three groups of BEAS-2B cells were prepared: control, 0.5 hour of PDBu stimulation, and 4 hours of PDBu stimulation. Each group consisted of three biological replicates.

The top two functional networks of genes were centered on NFκB and TNF-α, which are two commonly known pathways for cell death and inflammation. Subsequent tests confirmed the decrease in cell viability and increase in the production of various cytokines. Interestingly, each of the increased cytokines was differentially regulated at mRNA and/or protein levels by different sub-class of PKC isozymes.

Project description:We have developed a new model of the human airway epithelial cell by deriving the cell-specific metabolic reactions identified from (i) a draft automated model by Wang et al. 2017 (ii) gene expression datasets of the human airway epithelial cell (Deprez et al., 2020; Braga et al., 2020). (iii) We obtained additional reactions, gene-to-reaction associations and pathways (that were not in the automated model) from HumanCyc (Trupp et al., 2010) and (iv) performed stochastic and dynamic simulations on the model generated including manual curations from primary literature and Recon3D (Brunk et al., 2018). (v) We added the viral biomass maintenance function into the model, previously developed for the macrophage cell (Renz et al. 2020) to develop the new integrated model of the human airway epithelial cell and the SARS-CoV-2 virus, (iBBEC4660).

Project description:Epithelial-mesenchymal transition (EMT) plays a critical role in airway injury, repair, and structural remodeling. Although NFkB/RelA subnit is involved in late EMT-associated gene expression, RelA translocation is occurs later than early phases of IκB kinase (IKK)-depenedent gene expression. To investigate the hypothesis that IKK plays an independent mechanism in TGF-induced EMT, we conducted time-series proteomics and phosphoproteomics analysis of human airway epithelial cells in the absence or presence of a specific IKK inhibitor, BMS -345541.

Project description:We are interested in having the gene microarray done on untreated and PMA treated (10 nM x 24 hr) human and mouse epithelial cells lines including CALU-3, MLE-15, primary bronchial human airway epithelial cells. We are especially interested in seeing whether sialyl or sulfo transferases, and MUC genes, are present and if they are induced by PMA. We hope to use this information to optimize future experiments designed to identify Siglec lung ligands. The lab is interested in studying untreated and PMA treated (10 nM x 24 hr) human and mouse epithelial cells lines including CALU-3, MLE-15, primary bronchial human airway epithelial cells. With special interest in understanding whether sialyl or sulfo transferases, and MUC genes, are present and if they are induced by PMA.

Project description:Despite the appreciated in vivo role of the redox-active Pseudomonas virulence factor pyocyanin in Pseudomonas airway infections and the recognized importance of airway epithelial cells in combating bacterial pathogens, little is known about pyocyaninM-bM-^@M-^Ys effect on airway epithelial cells. We find that exposure of bronchiolar epithelial cells to pyocyanin results in MUC2/MUC5AC induction and mucin secretion mediated by reactive oxygen species production, activation of the epidermal growth factor receptor pathway and release of inflammatory cytokines (IL-1b, IL-6, TGFa, TNFa). Microarray analysis identified 286 pyocyanin-induced genes in airway epithelial cells, including many of the inflammatory mediators elevated in cystic fibrosis airways (G-CSF, GM-CSF, CXCL1, SAA). We also found several novel pyocyanin-responsive genes of potential importance in the infection process (IL-24, CXCL2, CXCL3, CCL20, SOD2). This comprehensive study uncovers numerous details of pyocyaninM-bM-^@M-^Ys proinflammatory action and establishes airway epithelial cells as key responders following exposure to this microbial toxin. H292 cells were treated with or without 8 uM pyocyanin for 48 hrs in serum-free RPMI medium. RNA was isolated in four independent experiments, collected, processed and subjected to microarray analysis simultaneously (biological repeats).

Project description:In the process of seeking novel lung host defense regulators by analyzing genome-wide RNA sequence data from normal human airway epithelium, we detected expression of POU2AF1, a known transcription co-factor previously thought to be expressed only in lymphocytes. Lymphocyte contamination of human airway epithelial samples obtained by bronchoscopy and brushing was excluded by immunohistochemistry staining, the observation of up-regulation of POU2AF1 in purified airway basal stem/progenitor cells undergoing differentiation and analysis of differentiating single basal cell clones. Lentivirus-mediated up-regulation of POU2AF1 in airway basal cells induced up-regulation of host defense genes, including MX1, IFIT3, IFITM and known POU2AF1 downstream genes HLA-DRA, ID2, ID3, IL6, BCL6. Interestingly, expression of these genes paralleled changes of POU2AF1 expression during airway epithelium differentiation in vitro, suggesting POU2AF1 helps to maintain a "host defense tone" even in pathogen-free condition. Cigarette smoke, a known risk factor for airway infection, suppressed POU2AF1 expression both in vivo in humans and in vitro in human airway epithelial cultures, accompanied by deregulation of POU2AF1 downstream genes. Finally, enhancing POU2AF1 expression in human airway epithelium attenuated the suppression of host defense genes by smoking. Together, these findings suggest a novel function of POU2AF1 as a potential regulator of host defense genes in the human airway epithelium. Methods: Massive parallel RNA sequencing was used to compare the transcriptome of lentivirus mediated POU2AF1 or RFP (control) gene expression in human primary airway epithelial cells (3 samples per group). Uninfected basal cell was used as a further control. Conclusions: The genes up-regulated by POU2AF1 in human airway epithelial cells are mainly related to the intracellular or extracellular anti-pathogen response, suggesting POU2AF1 plays a role in airway epithelial host defense. This Series represents samples complementary to those in GSE60989.
