Buffered hypercapnia alters the transcriptional profile in monocytes.

ABSTRACT: In monocytes we used RNA-sequencing to investigate the effect of 4hrs of exposure to buffered hypercapnia (10% CO2) compared to normocapnia (5% CO2) with and without the pro-inflammatory stimulus LPS (2.5ug/ml) for the final 2hrs. Buffered hypercapnia causes transcriptional changes associated with altered metabolic function in both the basal and stimulated states.

NR4A2 and NR4A3 selectively modulate elements of the monocyte response to buffered hypercapnia

Project description:In wild type, NR4A2-deficient, and NR4A3-deficient monocytes we used RNA-sequencing to investigate the effect of 4hrs of exposure to buffered hypercapnia (10% CO2) compared to normocapnia (5% CO2) with and without the pro-inflammatory stimulus LPS (2.5ug/ml) for the final 2hrs.

Hypercapnia Alters Expression of Immune Response, Nucleosome Assembly and Lipid Metabolism Genes in Differentiated Human Bronchial Epithelial Cells

Project description:Hypercapnia, the elevation of CO2 in blood and tissues, commonly occurs in severe acute and chronic respiratory diseases, and is associated with increased risk of mortality. Recent studies have shown that hypercapnia adversely affects innate immunity, host defense, lung edema clearance, and cell proliferation. Airway epithelial dysfunction is a feature of advanced lung disease, but the effect of hypercapnia on airway epithelium is unknown. Thus, in the current study we examined the effect of normoxic hypercapnia (20% CO2 for 24 h) vs normocapnia (5% CO2), on global gene expression in differentiated normal human airway epithelial cells. Gene expression was assessed on Affymetrix microarrays, and subjected to gene ontology analysis for biological process and cluster-network representation. We found that hypercapnia downregulated the expression of 183 genes and upregulated 126. Among these, major gene clusters linked to immune responses and nucleosome assembly were largely downregulated, while lipid metabolism genes were largely upregulated. The overwhelming majority of these genes were not previously known to be regulated by CO2. These changes in gene expression indicate the potential for hypercapnia to impact bronchial epithelial cell function in ways that may contribute to poor clinical outcomes in patients with severe acute or advanced chronic lung diseases.

Drosophila elevated CO2 (hypercapnia) microarray

Project description:The effects of elevated CO2 (hypercapnia) on organisms are not well known, nor are the molecular pathways by which organisms sense CO2. We have performed microarray analysis on Drosophila in order to develop a genetic model for better understanding the effects of CO2. Equal numbers of 5-day old male and female flies (at least 40 total) were exposed to 13% CO2 or air for 24h and RNA extracted. Gene expression changes in CO2 compared with air were analyzed. Experiments were performed in triplicate and the 3 separate microarray experiments are included.

Effect of Hypercapnia on Murine Ventilator-Induced Lung Injury

Project description:Addition of CO2 to the inspired gas can ameliorate lung injury during high tidal volume mechanical ventilation in animal models. Although some effects of hypercapnia on physiology and cell signaling have been characterized, we hypothesized that assessment of genome-wide gene expression patterns would reveal novel pathways of protection. We subjected male C57BL/6J mice to non-injurious low stretch (tidal vol = 10 mL/kg, PEEP = 2 cm H2O) or injurious high stretch (tidal volume approx 35 mL/kg, PEEP = 0 cm H2O) mechanical ventilation for 3 hours under normocapnia (FiCO2 = 0) or hypercapnia (FiCO2 = 0.12).

Hypercapnia alters Wnt production from PDGFR+ lung fibroblasts

Project description:Hypercapnia has deleterious effects on cell function, including inhibition of alveolar epithelial cells (AEC) and fibroblast proliferation without causing cell death. Classical studies and lineage-trace models demonstrated that fibroblast cells can affect the structurally and functionally distinct alveolar type 1 cells (AT1) and alveolar type 2 cells. This fibroblast cells reprogramming depends on certain signaling pathways that plays critical roles in tissue development and homeostasis throughout the organism lifespan.

Chronic hypercapnia-induced gene expression profiles in the brain

Project description:To test the hypothesis that increasing severity of chronic hypercapnia elicits distint gene expression profiles in important brainstem regions of cardiorespiratory control, three groups of goats (female; n=6/group) were exposed either 14 days of room air (RA), 14 days of 6% inspired CO2 (mild CH), or 7d of 6% InCO2 followed by 7d of 8% InCO2 (moderate CH). Following 14 days of exposure 4 target sites were collected (3 brainstem/1 cortical) for gene expression profiling analysis using bulk-tissue RNA-sequencing. Comparisons were made across all target sites comparing room air animals to either mild or moderate CH.

Hypercapnia impairs AT2 cell progenitor activity and promotes differentiation to AT1 cells

Project description:Hypercapnia has deleterious effects on cell function, including inhibition of alveolar epithelial cells (AEC) and fibroblast proliferation without causing cell death. Classical studies and lineage-trace models demonstrated that surfactant-producing AT2 cells can serve as stem cells for the structurally and functionally distinct alveolar type 1 cells (AT1) This AT2 reprogramming depends on Wnt/βcat signaling, a pathway that plays critical roles in tissue development and homeostasis throughout the organism lifespan. We found that high CO2 inhibits AT2 cell proliferation and self renewal, and promote their differentiation to ATEC and AT1 cells
