MetabolomicsDietary leucine restriction remodels the gut microbiota and serum glycerophospholipids to combat obesity

Abstract

Background The gut microbiota mediates dietary impacts on host metabolism, but the roles of specific amino acids remain elusive. We investigated the mechanism by which dietary leucine restriction combats obesity.

Methods Combining Mendelian randomization in humans with interv...

MetabolomicsMetabolome and proteome changes in skeletal muscle and blood of pre-weaning calves fed leucine and threonine supplemented diets

In pre-weaning calves, both leucine and threonine play important roles in growth and muscle metabolism. In this study, metabolomics, proteomics and clinical chemistry were used to assess the effects of leucine and threonine supplementation added to milk replacer on 14 newborn Holstein male calves...

MetabolomicsLeucine degradation metabolite ratio as a measure of meropenem susceptibility in carbapenem-resistant Klebsiella pneumoniae

Rapid detection of carbapenem-resistant Klebsiella pneumoniae (CRKP) is essential for effective clinical management and surveillance. This study investigated volatile organic compounds (VOCs) as phenotypic biomarkers of carbapenem resistance, with the goal of developing a translationally...

TranscriptomicsMolecular profiling of hypothalamic leucine-sensing neurons via PhosphoTRAP
To identify the molecular signature of leucine-activated neurons in the MBH, we adopted the PhosphoTRAP assay following parenchymal injection of leucine into the MBH. Neurons activated following MBH leucine injection (and expressing the neuronal activation marker cFos) co-express Ser240/244-phospho...

TranscriptomicsImproved transcription and translation with L-leucine stimulation of mTORC1
Roberts syndrome (RBS) is a human developmental disorder caused by mutations in the cohesin acetyltransferase ESCO2. We previously reported that mTORC1 was inhibited and overall translation was reduced in RBS cells. Treatment of RBS cells with L-leucine partially rescued mTOR function and protein sy...

MetabolomicsL-leucine increases the sensitivity of drug-resistant Salmonella to sarafloxacin by stimulating central carbon metabolism and increasing intracellular reactive oxygen species level (LC-MS positive mode)

The overuse of antibiotics has made public health and safety face a serious crisis. It is urgent to develop new clinical treatment methods to combat drug-resistant bacteria to alleviate the health crisis. The efficiency of antibiotics is closely related to the metabolic state of bacteria. However...

TranscriptomicsGenome-wide analysis of muscle gene expression in response to an intense cycling exercise. Effect of two protein-leucine enriched diets
Protein-leucine supplement ingestion following strenuous endurance exercise accentuates skeletal-muscle protein synthesis and adaptive molecular responses, but the underlying transcriptome is uncharacterized. In a randomized single-blind triple-crossover design, 12 trained men completed 100 min of h...
