(Submitter supplied) Purpose: To investigate molecular mechanisms of SARS-CoV-2-induced mucin expression and synthesis and test candidate countermeasures. Methods: Bulk RNA-seq was performed on well-differentiated human bronchial epithelial (HBE) cell culture lysates with/without SARS-CoV-2 inoculation. Results: SARS-CoV-2-infected HBE cultures exhibited peak titers 3 days post inoculation, whereas induction of MUC5B/MUC5AC peaked 7-14 days post inoculation. more...

(Submitter supplied) To help define the genes associated with mucus synthesis and secretion in the human small airway epithelium, we hypothesized that comparison of the transcriptomes of the small airway epithelium of individuals that express high vs low levels of MUC5AC, a major secretory mucin and the major component of airway mucus, could be used as a probe to identify the genes related to human small airway mucus production / secretion. more...

(Submitter supplied) Air pollution particulate matter <2.5 microns (PM2.5) is associated with poor respiratory outcomes. Mechanisms underlying PM2.5-induced lung pathobiology are poorly understood, but likely involve cellular and molecular changes to the airway epithelium. We extracted and chemically characterized the organic and water-soluble components of contemporary ambient air pollution PM2.5 samples. We then determined the whole transcriptome responses of human mucociliary airway epithelial cultures (n=12) to a dose series  of PM2.5 extracts. more...

(Submitter supplied) Purpose: To identify the cell types change and gene expression change under hypoxia on HBE cells. Methods: The primary human bronchial epithelial cells (HBE) were cultured on air-liquid interface (ALI) conditions. After 4 weeks, the cells were cultured under normoxic, symmetrical hypoxic (3.5% O2), or asymmetrical hypoxic (3.5% O2 basolateral with apical cap ~ 1% O2) conditions for 5 days. The cells were dissociated with Accutase solution and proceeded to scRNA-seq. more...

(Submitter supplied) Purpose: To identify the cell types change and gene expression change under hypoxia on HBE cells. Methods: The primary human bronchial epithelial cells (HBE) were cultured on air-liquid interface (ALI) conditions. After 4 weeks, the cells were cultured under normoxic or hypoxic (1% O2) conditions for 6h or 5days. The cells were dissociated with Accutase solution and proceeded to scRNA-seq. Results: Hypoxia did not induce any hypoxia-specific cell types, however, all cell types upregulated hypoxia-related, and senescence-related genes and downregulated cell proliferation genes.

(Submitter supplied) Purpose: To identify the gene expression change under hypoxia on HBE cells. Methods: bulk RNA-seq was performed on primary human bronchial epithelial cells (HBE) that were cultured on air-liquid interface (ALI) condition and treated under normoxia or hypoxia (1% O2) for 6hr, 24hr, and 5days. Results: hypoxia-related genes were significantly upregulated under hypoxia including EGLN3.

(Submitter supplied) Purpose: To identify the gene expression change under chronic hypoxia on HBE cells. Methods: bulk RNA-seq was performed on primary human bronchial epithelial cells (HBE) that were cultured on air-liquid interface (ALI) condition and treated under normoxia or hypoxia (1% O2) for 5days. Results: inflammatory cytokines, collagen degradation, and angiogenic genes were upregulated under chronic hypoxia.

(Submitter supplied) We present evidence on how a lung epithelial cell culture system based on human induced pluripotent stem cells (hiPSC) could emerge as a relevant and sensitive platform for modelling SARS-CoV-2 infection. In order to develop a human model system, we differentiated hiPSC into lung epithelial lineage (airway and alveolar cells) through a three-step protocol. De novo generated cells were authenticated by spatiotemporal expression of stage specific markers including SOX2, FOXJ1 and CC10 in proximal cells and SOX9, FOXP2, SFTPC, MUC5AC, and CC10 in distal cells. more...
