“…Previous metabolomics studies revealed metabolic alteration in the asthma exacerbated condition [32,[34][35][36]. Histidine, trimethylamine N-oxide, phenylacetylglycine, threonine, 4-aminohippurate and methylamine were decreased, whereas creatine, glucose, hippurate, alanine, glycolate, succinate, myo-inositol, dimethylamine, formate, homovanillate, acetylcarnitine, taurine, lactate, oxaloacetate, cis-aconitate, 2-methylglutarate, tyrosine, 1-methylhistamine, 2-hydroxyisobutyrate, acetone, carnitine, 3-methyladipate and 2-oxoglutarate were increased in asthmatic children during acute exacerbation.…”

Inhaled budesonide and salbutamol represent the most important and frequently used drugs in asthmatic children during acute exacerbation. However, there is still no consensus about their resulting metabolic derangements; thus, this study was conducted to determine the distinct metabolic profiles of these two drugs. A total of 69 children with asthma during acute exacerbation were included, and their serum and urine were investigated using high-resolution nuclear magnetic resonance (NMR). A metabolomics analysis was performed using a principal component analysis and orthogonal signal correction-partial least squares using SIMCA-P. The different metabolites were identified, and the distinct metabolic profiles were analysed using MetPA. A high-resolution NMR-based serum and urine metabolomics approach was established to study the overall metabolic changes after inhaled budesonide and salbutamol in asthmatic children during acute exacerbation. The perturbed metabolites included 22 different metabolites in the serum and 21 metabolites in the urine. Based on an integrated analysis, the changed metabolites included the following: increased 4-hydroxybutyrate, lactate, cis-aconitate, 5-hydroxyindoleacetate, taurine, trans-4-hydroxy-l-proline, tiglylglycine, 3-hydroxybutyrate, 3-methylhistidine, glucose, cis-aconitate, 2-deoxyinosine and 2-aminoadipate; and decreased alanine, glycerol, arginine, glycylproline, 2-hydroxy-3-methylvalerate, creatine, citrulline, glutamate, asparagine, 2-hydroxyvalerate, citrate, homoserine, histamine, sn-glycero-3-phosphocholine, sarcosine, ornithine, creatinine, glycine, isoleucine and trimethylamine N-oxide. The MetPA analysis revealed seven involved metabolic pathways: arginine and proline metabolism; taurine and hypotaurine metabolism; glycine, serine and threonine metabolism; glyoxylate and dicarboxylate metabolism; methane metabolism; citrate cycle; and pyruvate metabolism. The perturbed metabolic profiles suggest potential metabolic reprogramming associated with a combination treatment of inhaled budesonide and salbutamol in asthmatic children.Glucocorticoids and beta2 agonists represent the most important and frequently used drugs for symptom control in asthmatic children during acute exacerbation [1,2]. Current guidelines recommend the combined use of glucocorticoids and beta2 agonists as the preferred therapy for asthmatic children during acute exacerbation [3,4]. The glucocorticoid and beta2 agonist therapies are effective at controlling airway inflammation, reducing asthma symptoms, decreasing airway hyper-responsiveness and reducing the frequency and severity of exacerbations as well as asthma mortality. Despite their undoubted effectiveness and safety, there is still no consensus about the resulting metabolic derangements, including the development of dyslipidaemia, insulin resistance, glucose intolerance, diabetes, central adiposity and skeletal muscle wasting [5][6][7].Both glucocorticoids and beta2 agonists have the potential to influence glucose, lipid and protein...

“…Correspondingly, our recent metabolomics investigation of the plasma has further revealed promising allergic asthma-related metabolic biomarkers from the mouse model of OVA-induced allergic asthma [21]. Metabolites in lung tissue could directly reflect the pathophysiological state, and potentially generate unique perspectives for understanding disease mechanisms.…”

Asthma is a chronic inflammatory disorder of the airway and is characterized by airway remodeling, hyperresponsiveness, and shortness of breath. Modified Kushen Gancao Formula (mKG), derived from traditional Chinese herbal medicines (TCM), has been demonstrated to have good therapeutic effects on experimental allergic asthma. However, its anti-asthma mechanism remains currently unknown. In the present work, metabolomics studies of biochemical changes in the lung tissue and plasma of ovalbumin (OVA)-induced allergic asthma mice with mKG treatment were performed using ultra high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS). Partial least squares-discriminate analysis (PLS−DA) indicated that the metabolic perturbation induced by OVA was reduced after mKG treatment. A total of twenty-four metabolites involved in seven metabolic pathways were identified as potential biomarkers in the development of allergic asthma. Among them, myristic acid (L3 or P2), sphinganine (L6 or P4), and lysoPC(15:0) (L12 or P16) were detected both in lung tissue and plasma. Additionally, L-acetylcarnitine (L1), thromboxane B2 (L2), 10-HDoHE (L10), and 5-HETE (L11) were first reported to be potential biomarkers associated with allergic asthma. The treatment of mKG mediated all of those potential biomarkers except lysoPC(15:0) (P16). The anti-asthma mechanism of mKG can be achieved through the comprehensive regulation of multiple perturbed biomarkers and metabolic pathways.

“…Taken together, these results suggest that some changes occur in fish muscle that sustain life activities. Fatty acids are important constituents of cell membranes and the largest reserve in body [42]. However, fatty acids, not only in adipose tissue but also in muscle, contribute significantly to meat quality and the nutritional value of meat [43].…”

Background/Aims: Fish is a protein-rich food and is increasingly favored by consumers. It has been well recognized that the flesh composition of fish is closely related to its maturation and growth stage, but few studies have explored these differences. Additionally, hormone residues in fish after artificial induction of reproduction also attract consumer concern. In this study, we attempt to address these concerns by using a combination of transcriptomics and metabolomics analyses to identify key regulated pathways, genes, and metabolites that may affect the flesh nutrition of one typical aquaculture species in China, blunt snout bream (Megalobrama amblycephala). Methods: The four groups of fish were used for transcriptomics and metabolomics analyses, including one-year-old immature (group I), two-year-old immature (group II), two-year-old mature (group III) and successfully spawned (group IV) female M. amblycephala after artificial induction of reproduction. Results: We identified a total of 1460 differential compounds and 1107 differentially expressed unigenes in muscle among the different groups. Differential metabolites related to fish age (group II vs group I, group III vs group I) were largely enriched in “Glycerophospholipid metabolism”, “Linoleic acid metabolism”, “α-Linolenic acid metabolism”, and “Biosynthesis of unsaturated fatty acids”. Between these two pairwise comparisons, metabolites that are beneficial to human health, such as docosapentaenoic acid, α-Linolenic acid, eicosapentaenoic acid, and docosahexaenoic acid were found to be significantly decreased in two-year-old (group II, group III) compared with one-year-old (group I) M. amblycephala. Only one differential metabolite related to fish maturation, a triglyceride, was detected between groups III and II. Transcriptomics data showed that differently expressed genes (between group III vs group II, group III vs group I) related to maturation were highly enriched in “Cell adhesion molecules (CAMs)”, “Sphingolipid metabolism” and “Phagosome”. DEGs (between group II vs group I, group III vs group I) relating to fish age were enriched in the “cGMP-PKG signaling pathway”, “FoxO signaling pathway”, and “AMPK signaling pathway”. The gene-metabolite interaction network showed pivotal genes, including fumarate hydratase and GNPAT, which played a major role in the regulation of glycerphospholipid metabolism. The nutritional components were also measured, which verified the metabolomics results. Moreover, the metabolomics results showed that after 24 hours of artificial hormone injection, the drug was completely metabolized. Conclusion: Integrated analysis demonstrated that the nutrition value of fish fillet was much more related to fish age compared with maturation status in M. amblycephala females.
