Summary: Metabolomics approach revealed that the metabolism of nucleotides, alkaloids, amino acids, amides, and organic acids in mice is closely interrelated with E. granulosus infection. The study found that metabolic pathways in the liver such as tyrosine and tryptophan biosynthesis, phenylalanine, valine, leucine and isoleucine biosynthesis, and phenylalanine metabolism were notably associated with the occurrence and development of hydatid disease.

Summary: Recent studies have found that certain metabolites in the blood and urine are involved in the development of psoriasis, but the research on skin metabolomics for psoriasis is limited. In this study, researchers compared the metabolic profiles of lesional and nonlesional skin from 12 psoriasis patients using liquid chromatography-mass spectrometry. They identified several metabolites that were significantly different between lesional and nonlesional skin, mainly related to amino acid, lipid, and nucleotide metabolism. Fourteen potential biomarkers were identified, some of which were correlated with disease severity.

Summary: Plant metabolomics is widely used in plant physiology to study metabolic responses to environmental parameters. Derivatization followed by GC-MS metabolic profiling is a major technique for quantifying primary carbon, sulphur, and nitrogen metabolites. However, routine exact mass GC-MS analyses are not common due to the lack of dedicated databases. In this study, a curated database for exact mass metabolomics focused on primary metabolism was presented. The advantages of exact mass analyses were demonstrated, including resolving isotopic patterns, localizing S-containing metabolites, and avoiding identification errors. A practical example using Arabidopsis leaves showcased how exact mass GC-MS analysis can be used for plant samples and identify metabolic profiles.

Summary: Commercially used for treating chronic venous insufficiency, A. hippocastanum L. fruits contain beta-aescin which exhibits anti-inflammatory effects. However, diverse organ-specific secondary metabolites have been overlooked as potential pharmacological opportunities. Untargeted metabolomics analysis revealed unique chemical profiles in different organs of Aesculus plants, with fruits showing the highest antifungal and antioxidant activities. This suggests potential therapeutic leads for further exploration in the entire genus of Aesculus.

Summary: To improve the accuracy of retention time (RT) prediction, this study proposes a method called multi-data combinations and adaptive neural network (MDC-ANN). MDC-ANN establishes the RT prediction model for a target chromatographic system using transfer learning and a deep learning model trained on a large dataset. Experimental results demonstrate that integrating multiple molecular representations provides more information, improves RT prediction performance, and contributes to compound annotation. Different chromatographic systems may require different molecular representation combinations for accurate RT prediction. Hence, MDC-ANN, which automatically determines the best combination of molecular representations for a specific system, shows promise for accurate RT prediction in real applications.

Summary: A study found that PFECAs have inhibitory effects on cellular stress signals and lead to hepatomegaly in mice. Additionally, PFECAs also have inhibitory effects on glucocorticoid receptors, which may result in extensive suppression of stress signals.

Summary: Reliability, robustness, and interlaboratory comparability of quantitative measurements in clinical lipidomics studies are crucial. The different ex vivo stability of lipids in blood poses a risk to data interpretation. Clear recommendations for blood sample collection are necessary. In this study, we used UHPLC-high resolution mass spectrometry to investigate the stability of 417 lipid species in EDTA whole blood under different temperature conditions and time points. Our data suggest that cooling whole blood immediately and continuously, and separating plasma within 4 hours, unless focusing on robust lipids, are recommended. Lists of lipids' ex vivo (in)stability and potential biomarkers in whole blood are provided. Overall, our results contribute to the international efforts in achieving reliable and comparable clinical lipidomics studies in the future.

Summary: This study aimed to identify metabolites associated with incident acute coronary syndrome (ACS) and explore the causality of these associations. Three metabolites were found to be associated with ACS risk, including one that is a degradation product of a gut-brain peptide, one that is a marker of short-term glycemic excursions, and one that is a very-long-chain saturated fatty acid. These findings highlight the importance of gastrointestinal hormones and glycemic fluctuations in the development of ACS.

Summary: The gut microbiota plays a crucial role in maintaining host wellbeing by producing various metabolites. The assembly of the gut microbiome is influenced by postnatal factors, but little is known about the development of the gut metabolome. Our study reveals that geography has a significant impact on microbiome dynamics in the first year of life, with major compositional differences observed between Chinese and Swedish cohorts. We found that lipid metabolism, especially acylcarnitines and bile acids, is the most abundant metabolic pathway in the newborn gut, and delivery mode and feeding contribute to differences in the gut metabolome since birth.
