Molecular characterization of gene regulatory networks in primary human tracheal and bronchial epithelial cells.

ABSTRACT: 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.

Identification of miR-4423 as a Primate-Specific microRNA Highly Expressed in Ciliated Airway Epithelium and Associated with Lung Cancer [high throughput sequencing]

Project description:Smoking is a significant risk factor for lung cancer, the leading cause of cancer-related deaths worldwide. While microRNAs are regulators of many airway gene-expression changes induced by smoking, their role in modulating changes associated with lung cancer in these cells remains unknown. Here, we use next-generation sequencing of small RNAs in the airway to identify miR-4423 as a novel primate-specific microRNA associated with lung cancer and expressed primarily in mucociliary epithelium. The endogenous expression of miR-4423 increases as bronchial epithelial cells undergo differentiation into mucociliary epithelium in vitro and its overexpression during this process causes an increase in the number of ciliated cells. Furthermore, expression of miR-4423 is reduced in most lung tumors and in cytologically normal epithelium of the mainstem bronchus of smokers with lung cancer. In addition, ectopic expression of miR-4423 in a subset of lung cancer cell lines reduces their anchorage-independent growth and significantly decreases the size of the tumors formed in a mouse xenograft model. Consistent with these phenotypes, overexpression of miR-4423 induces a differentiated-like pattern of airway epithelium gene expression and reverses the expression of many genes that are altered in lung cancer. Together, our results indicate that miR-4423 is a novel regulator of airway epithelium differentiation and that the abrogation of its function contributes to lung carcinogenesis. Small RNA expression was profiled from pooled bronchial airway epithelial cell brushings (n=3 patients/pool) obtained during bronchoscopy from healthy never (NS) and current smokers (S) and smokers with (C) and without (NC) lung cancer. MicroRNA hsa-miR-4423 was over expressed in H1299, Calu6, SW900 and H2170 lung cancer cell lines.

An inflammatory memory of COVID-19 in airway basal stem cells impairs mucociliary differentiation (RNA-Seq)

Project description:Airway basal stem cells (BSCs) in chronic lung diseases accumulate memories to promote disease-specific pathogenesis. Whether acute lung infection also endows BSCs with an inflammatory memory to impair epithelial regeneration is unknown. Here, we derived multiple BSC lines from patients with and without COVID-19 (CoV19) using tracheal aspirate (TA) as a viable source of bronchial BSCs. While tested negative for SARS-CoV-2, BSC lines from CoV19 patients bore a proinflammatory gene signature, exhibited early cell cycle exist, and displayed goblet cell hypoplasia following differentiation in air-liquid interface (ALI). These phenotypes reproduced, at least partially, changes in BSCs in patients with CoV19 assessed by bioinformatic analysis of preexisting single cell transcriptomes of BSCs and by staining of lung sections for select markers. Such a memory in BSCs previously exposed to CoV19 was mediated by increases in chromosomal accessibility at key inflammatory gene loci associated with gene dysregulation and sustained STAT3 activation. Blockade of STAT3 hyperactivation in CoV19-exposed BSCs restored mucociliary differentiation in ALI. Taken together, BSCs acquire an epigenetic memory of CoV19 to impair epithelial regeneration. BSC derivation from TA provides a versatile approach to model airway epithelium in health and lung diseases.

Smoking is Associated with Shortened Airway Cilia

Project description:Background: Whereas cilia damage and reduced cilia beat frequency have been implicated as causative of reduced mucociliary clearance in smokers, theoretically mucociliary clearance could also be affected by cilia length. Based on models of mucociliary clearance predicting cilia length must exceed the 6 -7 μm airway surface fluid depth to generate force in the mucus layer, we hypothesized cilia height may be decreased in airway epithelium of normal smokers compared to nonsmokers. Methodology/Principal Findings: Cilia length in normal nonsmokers and smokers was evaluated in aldehyde-fixed, paraffin-embedded endobronchial biopsies, and air-dried and hydrated samples brushed from human airway epithelium via fiberoptic bronchoscopy. In 28 endobronchial biopsies, healthy smoker cilia length was reduced 15% compared to nonsmokers (p<0.05). In 47 air-dried samples of airway epithelial cells, smoker cilia length was reduced 13% compared to nonsmokers (p<0.0001). Analysis of the length of individual, detached cilia in 17 samples, smoker cilia length was reduced 9% compared to nonsmokers (p<0.05). Finally, in 16 fully hydrated, unfixed samples, smoker cilia length was reduced 7% compared to nonsmokers (p<0.05). Conclusions/significance: Models predict that a reduction in cilia length would reduce mucociliary clearance, suggesting that smoking-associated shorter airway epithelial cilia plays a significant role in the pathogenesis of smoking-induced lung disease.

Transcriptome analysis to investigate COPD exacerbations to influenza infection

Project description:Lung infection by influenza A viruses is a common cause of disease exacerbations in patients with chronic obstructive pulmonary disease (COPD), however, this process is difficult to study in human patients. Here we used a microfluidic human lung airway-on-a-chip (Airway Chip) lined by primary human bronchial epithelium interfaced with primary human pulmonary microvascular endothelium to model this process in vitro. Airway Chips containing bronchial epithelial cells from COPD patients successfully replicated the increased sensitivity to the lung airway to infection by both influenza H1N1 and H3N2 viruses compared to chips lined by epithelium from healthy donors, including enhanced viral loads and increased production of inflammatory cytokines. Transcriptomics analysis of the healthy and COPD epithelium following infection with influenza H1N1 virus on-chip resulted in identification of several novel markers of COPD

Transcription profiling of human trachea epithelium in smokers and non smokers

Project description:The initial site of smoking-induced lung disease is the small airway epithelium, which is difficult and time consuming to sample by fiberoptic bronchoscopy. We developed a rapid, office-based procedure to obtain trachea epithelium without conscious sedation from healthy nonsmokers (n=26) and healthy smokers (n=19, 27 ± 15 pack-yr). Gene expression differences [fold-change >1.5, p< 0.01, Benjamini-Hochberg correction] were assessed with Affymetrix microarrays. 1,057 probe sets were differentially expressed in healthy smokers vs nonsmokers, representing >500 genes. Trachea gene expression was compared to an independent group of small airway epithelial samples (n=23 healthy nonsmokers, n=19 healthy smokers, 25 ± 12 pack-yr). The trachea epithelium is more sensitive to smoking, responding with 3-fold more differentially-expressed genes than small airway epithelium. The trachea transcriptome paralleled the small airway epithelium, with 156 of 167 (93%) genes that are significantly up- and down-regulated by smoking in the small airway epithelium showing similar direction and magnitude of response to smoking in the trachea. Trachea epithelium can be obtained without conscious sedation, representing a less invasive surrogate “canary” for smoking-induced changes in the small airway epithelium. This should prove useful in epidemiologic studies correlating gene expression with clinical outcome in assessing smoking-induced lung disease. Experiment Overall Design: Tracheal gene expression: matched group of small airway epithelial samples (n=23 healthy non-smokers, n= 19 healthy smokers)

The Isolation and In vitro Differentiation of Primary Fetal Baboon Tracheal Epithelial Cells for the Study of SARS-CoV-2 Host-Virus Interactions

Project description:The mucociliary airway epithelium lines the human airways and is the primary site of host-environmental interactions in the lung. Following virus infection, airway epithelial cells initiate an innate immune response to suppress virus replication. Therefore, defining the virus-host interactions of the mucociliary airway epithelium is critical for understanding the mechanisms that regulate virus infection, including Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Non-human primates (NHP) are closely related to humans; and provide a model to study human disease. However, ethical considerations and high costs can restrict the use of in vivo NHP models. Therefore, there is a need to develop in vitro NHP models of human respiratory virus infection that would allow for rapidly characterizing virus tropism and suitability of specific NHP species to model human infection. Using the olive baboon (Papio anubis), we have developed methodologies for the isolation, in vitro expansion, cryopreservation, and mucociliary differentiation of primary fetal baboon tracheal epithelial cells (FBTECs). Furthermore, we demonstrate that in vitro differentiated FBTECs are permissive to SARS-CoV-2 infection and produce a potent host innate-immune response. In summary, we have developed an in vitro NHP model that provides a platform for the study of SARS-CoV-2 infection and other human respiratory viruses.
