Project description: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.
Project description: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. Results: Asymmetrical hypoxic cells showed more hypoxia-related responses than symmetrical hypoxic cells.
Project description: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.
Project description: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.
Project description:We investigated the interactions of four distinct betacoronaviruses; HCoV-OC43, SARS-CoV, MERS-CoV, and SARS-CoV-2 within human bronchial epithelial (HBE) organoids using single-cell RNA sequencing (scRNA-seq) to comprehensively understand betacoronaviruses cellular tropism and the intricate interplay between these cells and the host's immune defense mechanisms.
Project description:We carry out a comparative proteomic analysis of human bronchial epithelial cells from patients clinically treated or not with inhaled budesonide and stimulated or not with the viral mimic Poly(I:C).We also wanted to investigate the potential anti-viral effects of imiquimod, a TLR7 agonist, on the bronchial epithelial cells proteome in vitro.
