A systematic exploration of ginsenoside Rg5 reveals anti-inflammatory functions in airway mucosa cells.

Project description:BackgroundHyperactivated airway mucosa cells overproduce mucin and cause severe breathing complications. Here, we aimed to identify the effects of saponins derived from Panax ginseng on inflammation and mucin overproduction.MethodsNCI-H292 cells were pre-incubated with 16 saponins derived from P. ginseng, and mucin overproduction was induced by treatment with phorbol 12-myristate 13-acetate (PMA). Mucin protein MUC5AC was quantified by enzyme-linked immunosorbent assay, and mRNA levels were analyzed using quantitative polymerase chain reaction (qPCR). Moreover, we performed a transcriptome analysis of PMA-treated NCI-H292 cells in the absence or presence of Rg5, and differential gene expression was confirmed using qPCR. Phosphorylation levels of signaling molecules, and the abundance of lipid droplets, were measured by western blotting, flow cytometry, and confocal microscopy.ResultsGinsenoside Rg5 effectively reduced MUC5AC secretion and decreased MUC5AC mRNA levels. A systematic functional network analysis revealed that Rg5 upregulated cholesterol and glycerolipid metabolism, resulting in the production of lipid droplets to clear reactive oxygen species (ROS), and modulated the mitogen-activated protein kinase and nuclear factor (NF)-κB signaling pathways to regulate inflammatory responses. Rg5 induced the accumulation of lipid droplets and decreased cellular ROS levels, and N-acetyl-l-cysteine, a ROS inhibitor, reduced MUC5AC secretion via Rg5. Furthermore, Rg5 hampered the phosphorylation of extracellular signal-regulated kinase and p38 proteins, affecting the NF-κB signaling pathway and pro-inflammatory responses.ConclusionRg5 alleviated inflammatory responses by reducing mucin secretion and promoting lipid droplet-mediated ROS clearance. Therefore, Rg5 may have potential as a therapeutic agent to alleviate respiratory disorders caused by hyperactivation of mucosa cells.

Gene Expression Effects of IL-13 on Primary Human Airway Epithelial Cells

Project description:Primary culture airway epithelial cells, grown under physiologic air-liquid interface conditions, with, or without IL-13 in order to study the effects of this cytokine on mucous cell metaplasia, an important feature of asthma and COPD. Keywords: IL13, mucus, goblet cell RNA was isolated from primary culture airway epithelial cells grown at air-liquid interface, treated with or without IL-13 for 21 days.

Single cell transcriptome analysis of adult murine lung airway epithelium after NAPH-induced injury

Project description:To comprehensively study how club cells response to airway epithelial injury, we performed single cell transcriptomic analysis of the normal and NAPH injured lung samples. Our analysis reveals that a previously undescribed pathway promoting mucous metaplasia that involves VEGFa and its receptor KDR. Our single cell RNA sequencing analysis revealed that VEGFR2 (also known as FLK1 or KDR) is expressed in club cell subpopulations. Loss of KDR, its ligand VEGFa, or downstream MEK/ERK causes excessive differentiation of club cells into mucous cells (mainly goblet cells) during development and regeneration following Naphthalene (NAPH) challenge.

Ginsenoside CK improves cognitive impairment

Project description:Alzheimer's disease (AD) is a neurodegenerative disease and is the most common form of dementia, cognitive dysfunction is a pre-AD manifestation, followed by progressive deterioration in behavior and mood, CK has good pharmacological activity, inhibit neuronal damage associated with Aβ and improve learning memory in mice through its antioxidative properties. We used microarrays to detail the regulation of brain tissue genes in cognitively impaired mice by ginsenoside CK.

Effects of Myb shRNA on Airway Epithelial Cells

Project description:The epithelium of the pulmonary airway is specially differentiated to provide defense against environmental insults, but also subject to dysregulated differentiation that results in lung disease. The current paradigm for airway epithelial differentiation is a one-step program whereby a p63+ basal epithelial progenitor cell generates a ciliated or secretory cell lineage, but the cue for this transition and whether there are intermediate steps is poorly defined. Here we identify transcription factor Myb as a key regulator that permits early multilineage differentiation of airway epithelial cells. Myb+ cells were identified as p63– and therefore distinct from basal progenitor cells, but were still negative for markers of differentiation. Myb RNAi treatment of primary-culture airway epithelial cells and Myb gene deletion in mice resulted in a p63– population with failed maturation of Foxj1+ ciliated cells, as well as Scbg1a1+ and Muc5ac+ secretory cells. Consistent with these findings, analysis of whole genome expression of Myb-deficient cells identified Myb-dependent programs for ciliated and secretory cell differentiation. Myb+ cells were rare in human airways but were increased in regions of ciliated cells and mucous cell hyperplasia in samples from subjects with chronic obstructive pulmonary disease. Together, the results show that a p63– Myb+ population of airway epithelial cells represents a distinct intermediate stage of differentiation that is required under normal conditions and may be heightened in airway disease. 12 samples, 2x2 factorial design, factor 1: time (days post-ALI), factor 2:shRNA (Myb vs Scrambled Control), performed in triplicate (biological replicates)

Adult mucous neck cells from corpus gastric epithelium

Project description:In this experiment, mucous neck cells from the gastric epithelium of normal, adult C57/B6 mice were laser-capture microdissected to determine gene expression in neck cells relative to pit cells, parietal cells, and zymogenic cells, whose expression profiles were previously deposited in GEO.
