MetabolomicsNew plasma preparation approach to enrich metabolome coverage in untargeted metabolomics: plasma protein bound hydrophobic metabolite release with proteinase K
Plasma untargeted metabolomics is a common method for evaluation of the mechanisms underlying human pathologies and identification of novel biomarkers. The plasma proteins provide the environment for transport of hydrophobic metabolites. The current sample preparation protocol relies on the immediat...

MetabolomicsPCOS preterm plasma metabolome

This study investigated mid-trimester plasma metabolomic profiles in pregnant women to identify biomarkers associated with Polycystic Ovary Syndrome (PCOS) and preterm birth. A total of 149 participants were categorized into four groups: 32 with PCOS and preterm delivery, 34 with PCOS and term de...

MetabolomicsPregnancy-Induced Metabolic Phenotype Variations in Maternal Plasma
Metabolic variations occur during normal pregnancy to provide the growing fetus with a supply of nutrients required for its development and to ensure the health of the woman during gestation. Mass spectrometry-based metabolomics was employed to study the metabolic phenotype variations in the materna...

MetabolomicsAROMA-GC: Green Automated Plasma Metabolome Profiling

Metabolomics enables the comprehensive profiling of low–molecular weight metabolites that reflect the interplay between environmental exposures and endogenous biological processes. As the downstream output of genomic, transcriptomic, proteomic, and epigenomic networks, the metabolome provides the...

MetabolomicsHuman gut microbiota and plasma metabolomics in Mn-glucose metabolism correlation

Previous epidemiological and laboratorial studies have demonstrated a close relationship between plasma manganese (Mn) levels and type 2 diabetes (T2D), however, the underlying mechanism remains undisclosed. In this study, we employed a comprehensive approach that integrated fecal 16S rRNA sequen...

MetabolomicsImpacts of the Callipyge mutation on ovine plasma metabolites
The ovine Callipyge mutation causes postnatal muscle hypertrophy localized to the pelvic limbs and torso, as well as body leanness. The mechanism underpinning enhanced muscle mass is unclear, as is the systemic impact of the mutation. To investigate potential systemic effects of the mutation, 1H NMR...

MetabolomicsUntargeted Plasma Metabolomic Profiling of Parkinson’s Disease
Untargeted LC–MS metabolomic profiling was performed on plasma samples from a discovery cohort comprising 50 patients with Parkinson’s disease and 50 healthy controls. The study aimed to characterize disease-associated metabolic alterations, identify dysregulated metabolic pathways, and investigate ...

MetabolomicsImpact of myocardial reperfusion on human plasma lipidome
The primary aim of the study is to investigate the temporal changes in plasma lipidome before and after reperfusion in patients with ST-segment elevation myocardial infarction (STEMI) and their association with myocardial injury. We found that 56% of the identified lipid species were significantly a...

MetabolomicsUntargeted metabolomics analysis of COPD plasma

Background: Chronic obstructive pulmonary disease (COPD) is a progressive inflammatory disorder with rising global morbidity and mortality. Emerging evidence suggests that systemic metabolic alterations, particularly dyslipidemia, contribute to COPD pathogenesis. However, the mechanisms link...

MetabolomicsAssociation between altered tryptophan metabolism, plasma aryl hydrocarbon receptor agonists, and inflammatory Chagas disease

Chagas disease causes a cardiac illness characterized by immunoinflammatory reactions leading to myocardial fibrosis and remodeling. The development of Chronic Chagas Cardiomyopathy (CCC) in some patients while others remain asymptomatic is not fully understood, but dysregulated inflammatory resp...
