MetabolomicsUntargeted Metabolomics To Ascertain Antibiotic Modes of Action
Deciphering the mode of action (MOA) of new antibiotics discovered through phenotypic screening is of increasing importance. Metabolomics offers a potentially rapid and cost-effective means of identifying modes of action of drugs whose effects are mediated through changes in metabolism. Metabolomics...

MetabolomicsUntargeted LC–MS Metabolomic Analysis of Connexin 43 in Bone Metabolism

MC3T3-E1 cells were divided into two groups: si-NC and si-Connexin43. Cx43 expression was knocked down using siRNA transfection, followed by LC–MS-based untargeted metabolomic analysis to investigate metabolic alterations associated with Connexin 43 deficiency in osteoblasts and its potential rol...

MetabolomicsBridging Targeted (Zeno MRM-HR) and Untargeted (SWATH) LC–HRMS in a Single Run for Sensitive Exposomics

Traditionally, chemical exposure has been assessed by low-resolution mass spectrometry via targeted approaches due to the typically extremely low concentration of such compounds in biological samples. Nevertheless, untargeted approaches are now becoming a promising tool for a broader investigatio...

MetabolomicsHigh-Precision Automated Workflow for Urinary Untargeted Metabolomic Epidemiology
Urine is a non-invasive biofluid that is rich in polar metabolites and well-suited for metabolomic epidemiology. However, due to individual variability in health and hydration status, the physiological concentration of urine can differ >15-fold, which can pose major challenges in untargeted LC-MS me...

MetabolomicsUntargeted serum metabolomics of dairy goats under heat stress and melatonin supplementation
Serum untargeted metabolomic profiling was performed to characterize metabolic alterations induced by heat stress and to evaluate the potential protective effects of melatonin supplementation in dairy goats. Serum samples were collected from dairy goats assigned to three experimental groups: a norma...
