Special Issue Information

Dear Colleagues,

The analytical mass spectrometry applies irreplaceable approaches to chemical analysis, thus becoming a gold standard of the analytical practice, due to its superior instrumental features and performances. The method shows ultra-high accuracy, reliability, precision, reproducibility, selectivity, sensitivity, and specificity, together with the capability of low- and high-molecular weight analyses as well as very low concentration limits (attomole and fmol) of detection and quantitation of analytes, among other advantages of the mass spectrometric instrumentation. Mass spectrometric methods, among others, contribute crucially in developing clinical precision medicine, due to the requested, compulsory, high-analytical standards of implemented omics protocols. Mass spectrometric application fields include analytical and environmental chemistry, clinical diagnostics, laboratory medicine, petroleum chemistry, biochemistry, medicinal chemistry, pharmaceutical drug design, pharmacy, forensic chemistry and investigations for forensic medico-legal purposes, toxicology, nuclear forensics, food and agricultural science and technology, geology, archaeology, and more. Omics-methods for molecular identification, annotation, and quantification are used in metabolomics, (neuro)-proteomics, lipidomics, food-omics, steroid-omics, glycomics, pesticide analysis and control, genomics, DNA adduct-omics, transcriptomics, lignomics, interactomics, doping control, petrol-omics, isotomics, among others. Clinical trans-omics integrates clinical phenomena with mass spectrometric multi-omics approaches. The ultra-high precision and reliability of omics-protocols determine their implementation into clinical practice. The method performances should be traceable to significantly higher-order analytical standards, defining uncertainty via the criteria of statistics and chemometrics. Mass spectrometry is capable of determining molecular sequences and modifications. It addresses crucial questions on biological processes in vivo as well as provides the knowledge on the relation between molecular structure and biological function, both in vitro and in vivo. Mass spectrometric methods also utilise the techniques of isotope labelling analytes and H/D exchange, thus yielding the complete data on the structural consequences of biomacromolecules and the activation biochemical reactions of enzymes. This knowledge also significantly develops the field of biochemistry. Mass spectrometric tools also involve the imaging technique for mapping biologically active compounds in tissues. This thematic Second Edition of the Special Issue focuses on the field of analytical mass spectrometry, particularly, the field of biochemistry. While describing mass spectrometric ionization approaches, hard-ionization methods should be highlighted, for instance, inductively coupled plasma-mass spectrometry, which has been regarded as a method of choice for simultaneously quantifying the trace amounts of isotope ions of elements in biological fluids. Its protocols have also been routinely implemented in clinical laboratories.

As the former edition of the Special Issue, the Second Edition introduces the reader to the innovations and applications of soft- and hard-ionization mass spectrometric methods to comprehensively understand biochemical transformations in environmental, food, and biological samples.

The current study investigated the impact of cold stress on the morphological, physiological, and phytochemical properties of Juglans regia L. (J. regia) using in vitro microclone cultures. The study revealed significant stress-induced changes in the production of secondary antioxidant metabolites. According to gas chromatography–mass spectrometry (GC–MS) analyses, the stress conditions profoundly altered the metabolism of J. regia microclones. Although the overall spectrum of metabolites was reduced, the production of key secondary antioxidant metabolites significantly increased. Notably, there was a sevenfold (7×) increase in juglone concentration. These findings are crucial for advancing walnut metabolomics and enhancing our understanding of plant responses to abiotic stress factors. Additionally, study results aid in identifying the role of individual metabolites in these processes, which is essential for developing strategies to improve plant resilience and tolerance to adverse conditions.

Cholestasis is characterized by disrupted bile flow from the liver to the small intestine. Although etiologically different cholestasis displays similar symptoms, diverse factors can contribute to the progression of the disease and determine the appropriate therapeutic option. Therefore, stratifying cholestatic patients is essential for the development of tailor-made treatment strategies. Here, we have analyzed the liver proteome from cholestatic patients of different etiology. In total, 7161 proteins were identified and quantified, of which 263 were differentially expressed between control and cholestasis groups. These differential proteins point to deregulated cellular processes that explain part of the molecular framework of cholestasis progression. However, the clustering of different cholestasis types was limited. Therefore, a machine learning pipeline was designed to identify a panel of 20 differential proteins that segregate different cholestasis groups with high accuracy and sensitivity. In summary, proteomics combined with machine learning algorithms provides valuable insights into the molecular mechanisms of cholestasis progression and a panel of proteins to discriminate across different types of cholestasis. This strategy may prove useful in developing precision medicine approaches for patient care. Full article
