  • Peptidomics Mapping of Proteolysis Highlights Triple Activation of Sprouted Seeds by Germination, Homogenisation and Species Mixture.
    January 9, 2026 by MS Articles
    We investigated how seed proteolysis was enhanced by germination, by subsequent homogenisation (disrupting sprout compartments), and by co-incubation of homogenates from different species. Mass spectrometry of released peptides tracked proteolytic signatures from chickpea, lentil, mung and broccoli proteins, in soaked seeds, in sprouted seeds, and after sprout homogenisation followed by incubation alone or in mixture with other sprouts. The proteolytic […]

  • Machine Learning Combining with Ultra‐High Performance Liquid Chromatography‐Time‐of‐Flight Mass Spectrometry and Gas Chromatography‐Ion Mobility Chromatography Data Fusion for Geographical Origins Discrimination of Lonicerae japonicae Flos
    January 9, 2026 by MS Articles
    ABSTRACT The objective was to achieve accurate origins discriminations of flos of Lonicerae japonicae, especially those from the genuine and non-genuine producing areas. An integration strategy was proposed based on machine learning, combining ultra-high performance liquid chromatography-time-of-flight mass spectrometry and gas chromatography-ion mobility chromatography data fusion for geographical origins discrimination of flos of Lonicerae japonicae. Sixty-one batches of flos of […]
  • Quantification of serum myoglobin by liquid chromatography—isotope dilution mass spectrometry
    January 9, 2026 by MS Articles
    Human myoglobin (hMYO) is a sensitive early biomarker for acute myocardial infarction, rising within 1~3 h after myocardial injury and offering high predictive value for excluding infarction. To standardize its measurement, a precise quantitative method combining magnetic bead extraction with liquid chromatography–isotope dilution tandem mass spectrometry (LC‑IDMS/MS) was established. 15NLabeled myoglobin was spiked into serum as an internal standard, and magnetic […]

  • Simultaneous Capillary Electrophoresis – Mass Spectrometry profiling of (p)ppGpp and dinucleoside polyphosphates reveals oscillatory (p)ppGpp dynamics and a potential synchronisation between alarmones
    January 9, 2026 by MS Articles
    To survive stressful conditions, bacteria enter the stringent response mediated by the magic spot nucleotides (MSN) guanosine 3', 5' bispyrophosphate (ppGpp) and guanosine 3'-diphosphate 5' triphosphate (pppGpp). Another group of so-called alarmones elevated under stress are dinucleoside polyphosphates (NpnNs), such as diadenosine triphosphate (Ap3A). How these two groups of alarmones intersect with one another is poorly understood. Here, we present […]

  • The Red Rice Bran Extract (RRBE) Mitigates Photoaging by Targeting Mitochondrial Oxidative Stress and Regulating Thermal Damage Responses
    January 8, 2026 by MS Articles
    The photoprotective efficacy of natural skin-active complexes is well recognized, yet their application is often hindered by the challenge of deciphering their complex, multi-component, and multi-target mechanisms. To bridge the gap between established phenotypes and molecular mechanisms, we developed an AI-driven integrated platform that combines phytochemical profiling, network pharmacology, and deep learning-based target prediction with rigorous biophysical validation. We applied […]
  • Small molecule stabilization of diverse amyloidogenic immunoglobulin light chains revealed by hydrogen-deuterium exchange mass spectrometry
    January 8, 2026 by MS Articles
    Immunoglobulin light chains, a component of antibodies, can misfold and aggregate to cause systemic AL amyloidosis. Aggregation, including amyloid fibril formation, requires unfolding of the full-length light chain from its native state, and in most cases aberrant proteolysis. Small molecules that bind to the native state of light chains to stabilize them against conformational excursions and proteolysis are under development […]

  • Cysteine reactive chloroalkane probe enables HaloTag ligation for downstream chemical proteomics analysis.
    January 8, 2026 by MS Articles
    Chemical proteomics is a powerful method to track proteins labelled by reactive small molecules in living cells on proteome-wide scale. The strategy relies on reactivity and specificity of bioorthogonal click reactions. Although a variety of bioorthogonal reactions have been developed to facilitate chemical proteomics, their reactivity and specificity might not be comparable with enzymatic reactions. Here we describe an iodoacetamide […]
  • dia-PASEF Enables Rapid Profiling of the Human Secretome for Deeper Insights into Cellular Dynamics and Inflammatory Mechanisms
    January 8, 2026 by MS Articles
    Protein secretion is a fundamental mechanism for cellular coordination and signalling, with its dysregulation leading to widespread physiological dysfunction and disease. Immunoassay formats that utilise secondary antibody readouts are the current gold standard for measuring secreted proteins, offering high specificity and sensitivity, but relying on predefined protein panels that constrain the discovery of novel biology. We present a scalable mass […]
