From the different types of cancer, pancreatic cancer (PaC) has one of the lowest survival rates, with a survival rate of about 20% after the first year of diagnosis and about 8% after 5 years. The lack of highly sensitive and specific biomarkers, together with the absence of symptoms in the early stages, determines a late diagnosis, which is associated with a decrease in the effectiveness of medical intervention, regardless of its nature – surgery and/or chemotherapy. This review provides an updated overview of recent studies combining multi-OMICs approaches (<em>e.g.</em>, proteomics, metabolomics) with analytical tools, highlighting the synergy between high-throughput molecular data generation and precise analytical tools such as LC–MS, GC–MS and MALDI-TOF MS. This combination significantly improves the detection, quantification and identification of biomolecules in complex biological systems and represents the latest advances in understanding PaC management and the search for effective diagnostic tools.

Our study showed that the brevetoxin PbTx-2 had minimal influence on the physical activities of <em>M. mercenaria</em> for a short exposure time (24 hours). However, major metabolic level perturbations were observed in the clam gill extracts from the 1 ppb treatment. In addition, in the low concentration (0.1 ppb) study, clam gills showed combinational metabolite perturbations, as observed by an OPLS-DA study. The highly disturbed metabolites in the gill samples were the upregulated serine, glucose, hypotaurine, and glycine and the downregulated lactate, leucine, isoleucine, threonine, biotin, taurine, and valine. The results indicated that the brevetoxin PbTx-2 potentially affects glycolysis, glycine, serine, and threonine metabolism, taurine and hypotaurine metabolism, and biotin metabolism. While the digestive gland had less significantly changed metabolites, the potential combinational metabolite changes from PCA were observed from the 5-ppb treatment. Glucose and glycine are the primary metabolites that showed high contributions to the OPLS-DA model, which indicates the potential influence of digestive activities.

Although possible overlapping in the pathogenesis was expected, these processes have unique pathophysiological consequences. Therefore, we used HepG2 cells as a model system to investigate the impact of lipopolysaccharides (LPS) and free fatty acid (FFA; albumin conjugated palmitic acid) on the intracellular metabolome. Although both LPS and FFA triggered the expression of nuclear factor κB (NFκB)-dependent inflammation, only LPS treatment was able to trigger a Toll-like receptor 4 (TLR4) dependent response. The intracellular cytoprotective enzymatic levels (catalase, peroxidase, glutathione) were increased due to FFA but lowered due to LPS. The free-radical neutralizing efficacies of cell-free metabolites of FFA-treated cells were better than those of the LPS-treated ones. The use of untargeted metabolomics allowed for the identification of distinct metabolic pathway enrichments, providing further insights into the differential effects of LPS and FFA on the metabolism of hepatocytes.

Historically, much effort has been focused on labeling lysine and arginine residues due to their abundance on the protein periphery. The chemo-selectivity of these reagents is a challenging yet crucial parameter for deciphering properties specifically associated with the targeted amino acid. Consequently, there is a growing demand for new conjugation reagents and workflows that facilitate selective binding to amino acids other than lysine, cysteine, and arginine. Tyrosine, an aromatic amino acid, occurs moderately on the protein periphery, with its phenolic ring often buried within the tertiary protein structure. This presents a challenging environment for tyrosine-specific protein bioconjugation efforts. The hydrophobic aromatic side chain of tyrosine is known to engage in π-stacking interactions, while the hydroxyl group of the phenyl ring can participate in hydrogen bonding and form tyrosyl radicals involved in electron transfer. 4-Phenyl-3<em>H</em>-1,2,4-triazole-3,5(4<em>H</em>)-dione (PTAD) has been previously investigated for its ability to bind to tyrosine. This work presents an extensive structural proteomics investigation of tyrosine labeling across samples of varying complexity, ranging from peptides and proteins to entire cell lysates.

Despite the improved survival rates and prognosis observed in patients undergoing CCRT, over 30–40% do not achieve complete response and are at risk of locoregional recurrence. Targeting crucial molecules that confer resistance may improve the clinical outcomes of the treatment resistant patient cohort. Herein, we employed a liquid chromatography-tandem mass spectrometry (LC-MS/MS)-based phosphoproteomic approach to identify the altered phosphophorylation events, activated kinases and dysregulated pathways involved in treatment resistance. We quantified 2531 unique phosphopeptides mapping to 1099 proteins of which 74 proteins were differentially phosphorylated between the cohorts. Pathway analysis revealed dysregulation of the DNA repair pathway and the proteins involved in DNA repair in the non-responder cohort. Additionally, we identified kinase signature associated with CCRT resistance. Kinases such as CSNK2A1, PRKDC, PLK-1, NEK2, ATM and CDK1 are predicted to be activated in non-responders. In particular, we showed that CSNK2A1 is involved in oncogenesis of cervical cancer and pharmacological inhibition led to reduced cell proliferation, migration and colony formation. Moreover, the combination of the CSNK2A1 inhibitor, silmitasertib with cisplatin demonstrated synergism (combination index &lt; 1) and yielded a beneficial reduction in dosage. The dose reduced combination potentially reduced the proliferative, migratory and colony formation ability <em>in vitro</em>.

In the binary data approach, several VOMs exhibited patterns of high occurrence in some specific demographic groups.

In the semiquantitative approach, the relative abundance of cerumen VOMs was more impacted by sex and BMI than age and ethnicity/race.

Hence it is essential to identify potential microbe–drug associations (MDAs). Owing to the limitations of wet experiments, such as high costs and long durations, computational methods for binary classification tasks have become valuable alternatives for traditional experimental approaches. Since validated negative MDAs are absent in existing datasets, most methods randomly sample negatives from unlabeled data, which evidently leads to false negative issues. In this manuscript, we propose a novel model based on graph representation learning and positive-unlabeled learning (GRL–PUL), to infer potential MDAs. Firstly, we screen reliable negative samples by applying weighted matrix factorization and the PU-bagging strategy on the known microbe–drug bipartite network. Then, we combine muti-model attributes and constructed a microbe–drug heterogeneous network. After that, graph attention auto-encoder module, an encoder combining graph convolutional networks and graph attention networks, is introduced to extract informative embeddings based on the microbe–drug heterogeneous network. Lastly, we adopt a modified random forest as the final classifier. Comparison experiments with five baseline models on three benchmark datasets show that our model surpasses other methods in terms of the AUC, AUPR, ACC, F1-score and MCC. Moreover, several case studies show that GRL–PUL could capably predict latent MDAs.
