Targeted metabolomics to investigate antimicrobial activity of itaconic acid in marine molluscs. Metabolomics. 2019 Jun 22;15(7):97 Authors: Van Nguyen T, Alfaro AC Abstract INTRODUCTION: Itaconic acid (ITA) has recently been identified as an antimicrobial metabolite in mammalian immune cells. The presence of ITA was also reported in different tissues of marine molluscs, indicating its role as an endogenous metabolite of molluscs. In addition, the accumulation of ITA has been observed in different tissues of mussels following pathogen challenges. However, the concentration of ITA in mussel tissues and the possible role of this metabolite in the molluscan innate immune system remain unknown. OBJECTIVES: This study aims to quantitatively measure ITA levels in different tissues of marine mussels following an experimental challenge with Vibrio sp. DO1 isolate, and to identify the antimicrobial role of ITA in the innate immune system through the measurement of metabolic and immune alterations in tissues following the challenge. METHODS: In this study, adult Perna canaliculus mussels were experimentally challenged with a pathogenic Vibrio sp. DO1 isolate. The metabolite profiles of five different tissues, including mantle, gill, muscle, hepatopancreas and haemolymph were obtained, and levels of ITA in each tissue were characterized using a gas chromatography-mass spectrometry (GC-MS) metabolomics approach. Flow cytometry was also employed to measure cell health parameters, including oxidative stress via reactive oxygen species (ROS) production, apoptosis via changes in mitochondrial membrane potential (MMP) and haemocyte viability. RESULTS: The ITA levels in mantle, gill, muscle and hepatopancreas tissues at 18-h post infection (hpi) with Vibrio sp. were 40.31, 41.71, 11.61 and 41.66 ng mg-1, respectively. In haemolymph, the level of ITA was significantly increased from 95.25 ng ml-1 at 6 hpi to 174.36 ng ml-1 at 18 hpi and 572.12 ng ml-1 at 60 hpi. In line with the accumulation of ITA, we observed increased levels of metabolites within the tricarboxylic acid (TCA) cycle, anti-inflammatory metabolites and alterations of other metabolites associated with immune responses of the host. The flow cytometry analyses revealed increases in ROS production, apoptotic cells and decreases in cell viability. CONCLUSIONS: We reported on the production of ITA in different tissues of P. canaliculus mussels challenged with a marine pathogen which confirmed ITA as an antimicrobial metabolite. The findings revealed insights into the biosynthesis of ITA and suggests its role in antimicrobial and anti-inflammatory activities in the innate immune system. This study also provided insights into the innate immune system of bivalves and highlighted the potential use of ITA as a biomarker for shellfish health assessment in aquaculture.

Metabolic syndrome is an inflammatory disorder: A conspiracy between adipose tissue and phagocytes. Clin Chim Acta. 2019 Jun 20;: Authors: Reddy P, Lent-Schochet D, Ramakrishnan N, McLaughlin M, Jialal I Abstract Metabolic syndrome (MetS) describes a cluster of cardio-metabolic factors that predispose to type 2 diabetes mellitus (T2DM) and atherosclerotic cardiovascular disease (ASCVD). While 35% of Americans suffer from this disorder, the specific pathways related to this disease are largely underexplored. The prevailing consensus is that inflammatory pathways contribute to the pathogenesis of this disease, and therefore new research has uncovered how inflammation plays a critical role in the development and progression of MetS. The purpose of this review is to understand the role of major inflammatory mechanisms and their role in MetS. Our review identifies that adipose tissue (AT) contributes to the inflammatory pathways through the release of pro-inflammatory adipokines such as leptin and chemerin and dysregulation of anti-inflammatory adiponectin. Chemokines and cytokines deriving from monocytes are also altered and promote inflammation and insulin resistance. Circulating inflammatory biomarkers including C-reactive protein (CRP), fibrinogen, Serum amyloid A (SAA), cytokines, and chemokines have also been linked to the pathogenesis of MetS. Researchers have identified the significance of CRP levels in predicting future sequelae of MetS such as ASCVD. Mast cells in subcutaneous adipose tissue (SAT) promote both inflammation and fibrosis. Thus, both AT and phagocyte activity define MetS as an inflammatory disorder. PMID: 31229566 [PubMed - as supplied by publisher]

1H NMR-based metabolomics profiling and taste of boneless dry-cured hams during processing. Food Res Int. 2019 Aug;122:114-122 Authors: Zhang J, Yi Y, Pan D, Zhou G, Wang Y, Dang Y, He J, Li G, Cao J Abstract Boneless dry-cured hams were processed by raw material treatment (deboned and tumbled), salting (vacuum packed; 4 °C and 60-70% RH for 3.5 months), resting (vacuum packed; 15 °C and 60-70% RH for 1.5 months) and ripening (vacuum packed; 15 °C and 60-70% RH for 1.5 months). To explore the mechanisms that contributed to the taste of boneless dry-cured hams, 1H NMR-based metabolomics combined with multivariate data analysis was applied to investigate metabolite changes during processing. A total of 28 metabolites, including amino acids, peptide, organic acids, nucleic acids and their derivatives, sugars and others were identified. PC1 and PC2 explained a total of 77.6% and 18.0% of variables, and thus they could well reflect the main characteristics of all samples. The contents of most metabolites had an upward trend during the processing. Amino acids (isoleucine, valine, alanine, glutamate and histidine), organic acids (lactate, acetate, succinate, citrate and formate) and nucleotide derivative (hypoxanthine) were the major contributors to the taste in our final product. We concluded that the processing time (within 6.5 months) had a positive effect on the development of taste of boneless dry-cured hams. PMID: 31229062 [PubMed - in process]

Maternal serum metabolome and traffic-related air pollution exposure in pregnancy. Environ Int. 2019 Jun 19;130:104872 Authors: Yan Q, Liew Z, Uppal K, Cui X, Ling C, Heck JE, von Ehrenstein OS, Wu J, Walker DI, Jones DP, Ritz B Abstract BACKGROUND: Maternal exposure to traffic-related air pollution during pregnancy has been shown to increase the risk of adverse birth outcomes and neurodevelopmental disorders. By utilizing high-resolution metabolomics (HRM), we investigated perturbations of the maternal serum metabolome in response to traffic-related air pollution to identify biological mechanisms. METHODS: We retrieved stored mid-pregnancy serum samples from 160 mothers who lived in the Central Valley of California known for high air particulate levels. We estimated prenatal traffic-related air pollution exposure (carbon monoxide, nitric oxides, and particulate matter <2.5 μm) during first-trimester using the California Line Source Dispersion Model, version 4 (CALINE4) based on residential addresses recorded at birth. We used liquid chromatography-high resolution mass spectrometry to obtain untargeted metabolic profiles and partial least squares discriminant analysis (PLS-DA) to select metabolic features associated with air pollution exposure. Pathway analyses were employed to identify biologic pathways related to air pollution exposure. As potential confounders we included maternal age, maternal race/ethnicity, and maternal education. RESULTS: In total we extracted 4038 and 4957 metabolic features from maternal serum samples in hydrophilic interaction (HILIC) chromatography (positive ion mode) and C18 (negative ion mode) columns, respectively. After controlling for confounding factors, PLS-DA (Variable Importance in Projection (VIP) ≥2) yielded 181 and 251 metabolic features (HILIC and C18, respectively) that discriminated between the high (n = 98) and low exposed (n = 62). Pathway enrichment analysis for discriminatory features associated with air pollution indicated that in maternal serum oxidative stress and inflammation related pathways were altered, including linoleate, leukotriene, and prostaglandin pathways. CONCLUSION: The metabolomic features and pathways we found to be associated with air pollution exposure suggest that maternal exposure during pregnancy induces oxidative stress and inflammation pathways previously implicated in pregnancy complications and adverse outcomes.

Urine metabolites associated with cardiovascular effects from exposure of size-fractioned particulate matter in a subway environment: A randomized crossover study. Environ Int. 2019 Jun 19;130:104920 Authors: Zhang Y, Chu M, Zhang J, Duan J, Hu D, Zhang W, Yang X, Jia X, Deng F, Sun Z Abstract BACKGROUND: Ambient particulate matter (PM) is closely associated with morbidity and mortality from cardiovascular disease. Urine metabolites can be used as a non-invasive means to explore biological mechanisms for such associations, yet has not been performed in relation to different sizes of PM. In this randomized crossover study, we used metabolomics approach to explore the urine biomarkers linked with cardiovascular effects after PM exposure in a subway environment. METHODS AND RESULTS: Thirty-nine subjects were exposed to PM for 4 h in subway system, with either a respirator intervention phase (RIP) with facemask and no intervention phase (NIP) in random order with a 2-week washout period. Electrocardiogram (ECG) parameters and ambulatory blood pressure (BP) were monitored during the whole riding period and urine samples were collected for metabolomics analysis. After exposure to PM for 4 h in subway system, 4 urine metabolites in male and 7 urine metabolites in female were screened out by UPLC/Q-TOF MS/MS-based metabolomics approach. Cardiovascular parameters (HRV and HR) predominantly decreased in response to all size-fractions of PM and were more sensitive in response to different size-fractioned PM in males than females. Besides LF/HF, most of the HRV indices decrease induced by the increase of all size-fractioned PM while PM1.0 was found as the most influential one on indicators of cardiovascular effects and urine metabolites both genders. Prolyl-arginine and 8-OHdG were found to have opposing role regards to HRV and HR in male. CONCLUSION: Our data indicated that short-term exposure to PM in a subway environment may increase the risk of cardiovascular disease as well as affect urine metabolites in a size dependent manner (besides PM0.5), and male were more prone to trigger the cardiovascular events than female after exposure to PM; whereas wearing facemask could effectively reduce the adverse effects caused by PM.

Metabolomics. 2019 Jun 21;15(7):96 Authors: Zhou J, Sun L, Chen L, Liu S, Zhong L, Cui M Abstract INTRODUCTION: Atrial fibrillation (AF) is an abnormal heart rhythm characterized by an irregular beating of the atria and is associated with an increased risk of heart failure, dementia, and stroke. Currently, the perturbation of plasma content due to AF disease onset is not well known. OBJECTIVES: To investigate dysregulated molecules in blood plasma of untreated AF patients, with the goal of identifying biomarkers for disease screening and pathological studies. METHODS: LC-MS based untargeted metabolomics, lipidomics and proteomics analyses were performed to find candidate biomarkers. A targeted quantification assay and an ELISA were performed to validate the results of the omics analyses. RESULTS: We found that 24 metabolites, 16 lipids and 16 proteins were significantly dysregulated in AF patients. Pathway enrichment analysis showed that the purine metabolic pathway and fatty acid metabolism were perturbed by AF onset. FA 20:2 and FA 22:4 show great linear correlational relationship with the left atrial area and could be considered for AF disease stage monitoring or prognosis evaluation. CONCLUSION: we used a comprehensive multiple-omics strategy to systematically investigate the dysregulated molecules in the plasma of AF patients, thereby revealing potential biomarkers for diagnosis and providing information for pathological studies.

Related Articles Metabolomics of childhood exposure to perfluoroalkyl substances: a cross-sectional study. Metabolomics. 2019 Jun 21;15(7):95 Authors: Kingsley SL, Walker DI, Calafat AM, Chen A, Papandonatos GD, Xu Y, Jones DP, Lanphear BP, Pennell KD, Braun JM Abstract INTRODUCTION: Exposure to perfluoroalkyl substances (PFAS), synthetic and persistent chemicals used in commercial and industrial processes, are associated with cardiometabolic dysfunction and related risk factors including reduced birth weight, excess adiposity, and dyslipidemia. Identifying the metabolic changes induced by PFAS exposure could enhance our understanding of biological pathways underlying PFAS toxicity. OBJECTIVE: To identify metabolic alterations associated with serum concentrations of four PFAS in children using a metabolome-wide association study. METHODS: We performed untargeted metabolomic profiling by liquid chromatography with ultra-high-resolution mass spectrometry, and separately quantified serum concentrations of perfluorooctanoic acid, perfluorooctanesulfonic acid, perfluorononanoic acid, and perfluorohexanesulfonic acid (PFHxS) for 114 8-year old children from Cincinnati, OH. We evaluated associations between each serum PFAS concentration and 16,097 metabolic features using linear regression adjusted for child age, sex, and race with a false discovery rate < 20%. We annotated PFAS-associated metabolites and conducted pathway enrichment analyses. RESULTS: Serum PFAS concentrations were associated with metabolic features annotated primarily as lipids and dietary factors. Biological pathways associated with all four PFAS included arginine, proline, aspartate, asparagine, and butanoate metabolism. CONCLUSIONS: In this cross-sectional study, childhood serum PFAS concentrations were correlated with metabolic pathways related to energy production and catabolism. Future studies should determine whether these pathways mediate associations between PFAS exposure and childhood cardiometabolic health. PMID: 31227916 [PubMed - in process]

Related Articles Integrated multiomic analysis reveals comprehensive tumour heterogeneity and novel immunophenotypic classification in hepatocellular carcinomas. Gut. 2019 Jun 21;: Authors: Zhang Q, Lou Y, Yang J, Wang J, Feng J, Zhao Y, Wang L, Huang X, Fu Q, Ye M, Zhang X, Chen Y, Ma C, Ge H, Wang J, Wu J, Wei T, Chen Q, Wu J, Yu C, Xiao Y, Feng X, Guo G, Liang T, Bai X Abstract OBJECTIVE: Hepatocellular carcinoma (HCC) is heterogeneous, especially in multifocal tumours, which decreases the efficacy of clinical treatments. Understanding tumour heterogeneity is critical when developing novel treatment strategies. However, a comprehensive investigation of tumour heterogeneity in HCC is lacking, and the available evidence regarding tumour heterogeneity has not led to improvements in clinical practice. DESIGN: We harvested 42 samples from eight HCC patients and evaluated tumour heterogeneity using whole-exome sequencing, RNA sequencing, mass spectrometry-based proteomics and metabolomics, cytometry by time-of-flight, and single-cell analysis. Immunohistochemistry and quantitative polymerase chain reactions were performed to confirm the expression levels of genes. Three independent cohorts were further used to validate the findings. RESULTS: Tumour heterogeneity is considerable with regard to the genomes, transcriptomes, proteomes, and metabolomes of lesions and tumours. The immune status of the HCC microenvironment was relatively less heterogenous. Targeting local immunity could be a suitable intervention with balanced precision and practicability. By clustering immune cells in the HCC microenvironment, we identified three distinctive HCC subtypes with immunocompetent, immunodeficient, and immunosuppressive features. We further revealed the specific metabolic features and cytokine/chemokine expression levels of the different subtypes. Determining the expression levels of CD45 and Foxp3 using immunohistochemistry facilitated the correct classification of HCC patients and the prediction of their prognosis. CONCLUSION: There is comprehensive intratumoral and intertumoral heterogeneity in all dimensions of HCC. Based on the results, we propose a novel immunophenotypic classification of HCCs that facilitates prognostic prediction and may support decision making with regard to the choice of therapy.

Related Articles Evolutionary Metabolomics Identifies Substantial Metabolic Divergence between Maize and its Wild Ancestor, Teosinte. Plant Cell. 2019 Jun 21;: Authors: Xu G, Cao J, Wang X, Chen Q, Jin W, Li Z, Tian F Abstract Maize was domesticated from its wild ancestor, teosinte. Maize's new morphology and adaptation to diverse environments require coordinated changes in various metabolic pathways. However, how the metabolome was reshaped since domestication remains poorly understood. Here, we report a comprehensive assessment of divergence in the seedling metabolome between maize and teosinte. A total of 461 metabolites exhibited significant divergence due to selection. Interestingly, teosinte, tropical and temperate maize, representing major stages of maize evolution, targeted distinct sets of metabolites. Alkaloids, terpenoids and lipids were specifically targeted in the divergence between teosinte and tropical maize, while benzoxazinoids were specifically targeted in the divergence between tropical and temperate maize. To identify genetic factors controlling metabolic divergence, we assayed the seedling metabolome of a large maize-by-teosinte cross population. We show that the recent metabolic divergence between tropical and temperate maize tended to have simpler genetic architecture than the divergence between teosinte and tropical maize. Through integrating transcriptome data, we identified candidate genes contributing to metabolic divergence, many of which were under selection at nucleotide and transcript levels. Through overexpression or mutant analysis, we verified the roles of FHT1, Pr1, and ZmTPS1 in the divergence of their related biosynthesis pathways. Our findings not only provide important insights into domestication-associated changes in metabolism but also highlight the power of combining omics data for trait dissection.

Related Articles Polycyclic aromatic compounds in urban air and associated inhalation cancer risks: A case study targeting distinct source sectors. Environ Pollut. 2019 Jun 06;: Authors: Jariyasopit N, Tung P, Su K, Halappanavar S, Evans GJ, Su Y, Khoomrung S, Harner T Abstract Passive air sampling was conducted in Toronto and the Greater Toronto Area from 2016 to 2017 for 6 periods, in order to investigate ambient levels of polycyclic aromatic compounds (PACs) associated with different source types. The selected sampling sites (n = 8) cover geographical areas with varying source emissions including background, traffic, urban, industrial and residential sites. Passive air samples were analyzed for PACs which include PAHs, alkylated PAHs (alk-PAHs), dibenzothiophene and alkylated dibenzothiophenes (DBTs) and results for PAHs were used to calculate inhalation cancer risks using different approaches. The samples were also characterized for PAH derivatives including nitrated PAHs (NPAHs) and oxygenated PAHs (OPAHs). Concentrations of Σalk-PAHs and DBTs, which are known to be enriched in fossil fuels, as well as ΣNPAHs, were highest at a traffic site (MECP) located adjacent to the 18-lane Highway 401 that runs across Toronto. Except for an industrial site (HH/BU), PAC compositions were similar across the sampling sites with Σalk-PAHs being the most abundant class of PACs suggesting traffic emission was a major contributor to PACs in the atmosphere of Toronto. The industrial site exhibited a distinct chemical composition with ΣPAHs dominating over Σalk-PAHs and with elevated levels of fluoranthene, 9-nitroanthracene, and 9,10-anthraquinone, which likely reflects emissions from nearby industrial sources. MECP and HH/BU exhibited higher lifetime excess inhalation cancer risks indicating an association with traffic and industrial sources. The importance of the traffic sector as a source of PACs to ambient air is further supported by strong correlations of the ΣPAHs, Σalk-PAHs, DBTs, and ΣOPAHs with NOx. This study highlights the importance of traffic as an emission source of PACs to urban air and the relevance of PAC classes other than just unsubstituted PAHs that are important but currently not included in air quality guidelines or for assessing inhalation cancer risks.

Related Articles Effectiveness of a muticomponent workout program integrated in an evidence based multimodal program in hyperfrail elderly patients: POWERAGING randomized clinical trial protocol. BMC Geriatr. 2019 Jun 21;19(1):171 Authors: González-Sánchez M, Cuesta-Vargas AI, Del Mar Rodríguez González M, Caro ED, Núñez GO, Galán-Mercant A, Belmonte JJB Abstract BACKGROUND: Short-term and mid-term comparison of the efficacy of a multimodal program that incorporates a therapeutic workout program, medication review, diet adjustment and health education, in comparison to the standard medical practice in the improvement of the neuromuscular and physiological condition. Furthermore, it is intended to analyse the maintenance of these effects in a long-term follow-up (12 months) from the onset of the intervention. METHODS: A randomized clinical trial of elderly frail patients drawn from the Clinical Management Unit "Tiro de Pichón", Health District of Malaga, will be included in the study (after meeting the inclusion / exclusion criteria) will be randomized in two groups: a control group that will undergo an intervention consistent of medication review + diet adjustment + health education (regular workout recommendations within a complete advice on healthy lifestyles) and an experimental group whose intervention will consist of a multimodal treatment: therapeutic workout program+ medication review+ diet adjustment + health education. The sociodemographic, clinical and tracing variables will be reflected at the beginning of the study. In addition, the follow-up variables will be gathered at the second and sixth months after the beginning of the treatment and at the third and sixth months after the treatment (follow-up). The follow-up variables that will be measured are: body mass index, general health condition, fatigue, frailty, motor control, attention- concentration- memory, motor memory, spatial orientation, grip strength, balance (static, semi-dynamic), gait speed and metabolomics. A descriptive analysis of the sociodemographic variables of the participants will be conducted. One-Factor ANOVA will be used for the Within-Subject analysis and as for the Between-Subject analysis, the outcome variables between both the groups in each moment of the data collection will be compared. DISCUSSION: A multimodal program that incorporates a therapeutic workout program, medication review, diet adjustment and health education may be effective treatment to reduce the functional decline in elderly. The results of the study will provide information on the possible strengths and benefits in multimodal program in elderly. TRIAL REGISTRATION: ClinicalTrials.gov NCT02772952 registered May 2017.

Related Articles A Quantitative HILIC-MS/MS Assay of the Metabolic Response of Huh-7 Cells Exposed to 2,3,7,8-Tetrachlorodibenzo-p-Dioxin. Metabolites. 2019 Jun 20;9(6): Authors: Liu Q, Cai J, Nichols RG, Tian Y, Zhang J, Smith PB, Wang Y, Yan C, Patterson AD Abstract A hydrophilic interaction liquid chromatography (HILIC)-ultra high-pressure liquid chromatography (UHPLC) coupled with tandem mass spectrometry (MS/MS) method was developed and applied to profile metabolite changes in human Huh-7 cells exposed to the potent aryl hydrocarbon receptor (AHR) ligand 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). Comparisons of sensitivity (limit of detection as low as 0.01 µM) and reproducibility (84% of compounds had an interday relative standard deviation (RSD) less than 10.0%; 83% of compounds had an intraday RSD less than 15.0%) were assessed for all the metabolites. The exposure of Huh-7 cells to the hepatotoxic carcinogen TCDD at low doses (1 nM and 10 nM for 4 h and 24 h, respectively) was reflected by the disturbance of amino acid metabolism, energy metabolism (glycolysis, TCA cycle), and nucleic acid metabolism. TCDD caused a significant decrease in amino acids such as serine, alanine, and proline while promoting an increase in arginine levels with 24 h treatment. Energy metabolism intermediates such as phosphoenolpyruvate and acetyl-CoA and nucleosides such as UMP, XMP, and CMP were also markedly decreased. These results support the application of HILIC-UHPLC-MS/MS for robust and reliable analysis of the cellular response to environmentally relevant toxicants at lower doses. PMID: 31226775 [PubMed]
