MetabolomicsImmunomodulatory fecal metabolites are associated with mortality in COVID-19 patients with respiratory failure
Respiratory failure and mortality from COVID-19 result from virus- and inflammation-induced lung tissue damage. The intestinal microbiome and associated metabolites are implicated in immune responses to respiratory viral infections, however their impact on progression of severe COVID-19 remains uncl...

MetabolomicsAirway Dysbiosis Accelerates Lung Function Decline in Chronic Obstructive Pulmonary Disease (Human UPLC-MS/MS assays)

Progressive decline in lung function is a hallmark of chronic obstructive pulmonary disease (COPD). Although airway dysbiosis occurs in COPD, whether it contributes to disease progression remains unknown. Here, through a longitudinal analysis on 181 COPD individuals from two large cohorts involvi...

MetabolomicsSerum metabolomics analysis of patients with chronic obstructive pulmonary disease and 'frequent exacerbator' phenotype

BACKGROUND: Chronic obstructive pulmonary disease (COPD) exacerbations significantly contribute to morbidity and mortality. The complex nature of COPD presents challenges in accurately predicting and understanding frequent exacerbations.

OBJECTIVE: This stu...

TranscriptomicsCombined Chronic Toxicity and Carcinogenicity of Aerosol from a Heated Tobacco Product (microRNA data).
Smoking cessation is the most effective measure for reducing the risk of smoking-related diseases but switching to less harmful products (modified-risk tobacco products) can be an alternative for smokers who would otherwise not quit. In an 18-month chronic carcinogenicity/toxicity study in A/J mice ...

MetabolomicsAirway Dysbiosis Accelerates Lung Function Decline in Chronic Obstructive Pulmonary Disease (Murine UPLC-MS/MS assays)

Progressive lung function decline is a hallmark of chronic obstructive pulmonary disease (COPD). Airway dysbiosis occurs in COPD, but whether it contributes to disease progression remains unknown. Here we showed, through a longitudinal analysis on two cohorts involving four UK centers, that basel...

TranscriptomicsCombined Chronic Toxicity and Carcinogenicity of Aerosol from a Heated Tobacco Product (mRNA data)
Smoking cessation is the most effective measure for reducing the risk of smoking-related diseases but switching to less harmful products (modified-risk tobacco products) can be an alternative for smokers who would otherwise not quit. In an 18-month chronic carcinogenicity/toxicity study in A/J mice ...

MetabolomicsMulti-omic Landscape of Airway Microbe-Host Interactions in Chronic Obstructive Pulmonary Disease

The mechanistic role of the airway microbiome in chronic obstructive pulmonary disease (COPD) remains largely unexplored. We present a landscape of airway microbe-host interactions in COPD by an in-depth profiling of sputum metagenome, metabolome, host transcriptome and proteome from 99 COPD pati...

MetabolomicsChronic sleep loss sensitizes Drosophila melanogaster to nitrogen stress

Chronic sleep loss profoundly impacts metabolic health and shortens lifespan, but studies of the mechanisms involved have focused largely on acute sleep deprivation. To identify metabolic consequences of chronically reduced sleep, we conducted unbiased metabolomics on heads of three adult Drosoph...

TranscriptomicsCritical COPD respiratory illness is linked to increased transcriptomic activity of neutrophil proteases genes.
Abstract
BACKGROUND: Gene expression profiling (GEP) in cells obtained from peripheral blood has demonstrated to be a very useful approach for biomarker discovery and for studying molecular pathogenesis of prevalent diseases. While there is limited literature availble on gene expression markers a...

TranscriptomicsGene expression profiling in blood of patients with chronic respiratory failure
Genes dysregulated in cystic fibrosis (CF) and primary pulmonary arterial hypertension (PAH) at a late stage of pulmonary failure are still largely unknown. Blood samples taken in the frame of the French cohort of lung transplantation COLT offers the opportunity to identify in blood specific gene si...
