MetabolomicsEffect of probiotics intervention on short chain fatty acids in irradiated mice

In order to study the effect of probiotic intervention on short-chain fatty acids in irradiated mice, we collected feces, blood, and brain tissues from irradiated mice. The content of short-chain fatty acids was determined by High Performance Liquid Chromatography-mass spectrum. Further investiga...

MetabolomicsRumen unprotected glucose tends to promote intramuscular fat deposition via microbial volatile fatty acid-mediated metabolic reprogramming in cattle: A multi-omics perspective through the rumen-jejunum axis

Background: The regulatory effects of glucose absorption at different sites (rumen vs. small intestine) on lipid metabolism exhibit significant variation in beef nutrition. This study aimed to investigate the regulatory pathways of rumen-protected or unprotected glucose on lipid metabolism throug...

MetabolomicsCryogenic OrbiSIMS Localizes Semi-Volatile Molecules in Biological Tissues
OrbiSIMS is a recently developed instrument for label-free imaging of chemicals with micron spatial resolution and high mass resolution. We report a cryogenic workflow for OrbiSIMS (Cryo-OrbiSIMS) that improves chemical detection of lipids and other biomolecules in tissues. Cryo-OrbiSIMS boosts ioni...

MetabolomicsStrong effect of Penicillium roqueforti populations on volatile and metabolic compounds responsible for aromas, flavour and texture in blue cheeses
Studies of food microorganism domestication can provide important insight into adaptation mechanisms and lead to commercial applications. Penicillium roqueforti is a fungus with four genetically differentiated populations, two of which were independently domesticated for blue cheese-making, with the...

MetabolomicsEffects of Magnesium Potassium Sulfate on Tibetan Sheep Quality and Its Volatile and Non-Volatile Metabolic Substancesate the publication title

Preliminary research conducted by the team has identified that potassium and magnesium may influence the quality of Tibetan lamb meat, although the underlying mechanisms remain unclear. This study aims to examine the impact of dietary supplementation with magnesium potassium sulfate (PMS) on the ...

MetabolomicsQuantitative trait loci analysis identifies a prominent gene involved in the production of fatty-acid-derived flavor volatiles in tomato
To gain insight into the genetic regulation of lipid metabolism in tomato, we conducted metabolic trait loci (mQTL) analysis following the lipidomic profiling of fruit pericarp and leaf tissue of the Solanum pennellii introgression lines. To enhance mapping resolution for selected fruit-specific mQT...

MetabolomicsMulti-omics analysis reveals maternal gut microbiota-derived short-chain fatty acids and progesterone are associated with offspring birth weight in sows

Piglet birth weight is a key determinant of preweaning survival and subsequent growth performance, yet the role of maternal gut microbiota in relation to offspring birth weight in sows remains incompletely characterized. This study aimed to investigate the association between maternal gut microbi...

MetabolomicsMicrobial community-scale metabolic modelling predicts personalized short-chain fatty acid production profiles in the human gut
Microbially derived short-chain fatty acids (SCFAs) in the human gut are tightly coupled to host metabolism, immune regulation and integrity of the intestinal epithelium. However, the production of SCFAs can vary widely between individuals consuming the same diet, with lower levels often associated ...
