MetabolomicsATP-binding Cassette Sub-family C Member 5 (ABCC5) Functions as an Efflux Transporter of Glutamate Conjugates and Analogs
The ubiquitous efflux transporter ATP-binding cassette sub-family C member 5 (ABCC5) is present at high levels in the blood-brain barrier, neurons and glia, but its function is not known. Untargeted metabolomic screens revealed that Abcc5-/- mice accumulate endogenous glutamate conjugates in several...

MetabolomicsRedirected nuclear glutamate dehydrogenase supplies Tet3 with α-ketoglutarate in neurons

Tet3 is the main α-ketoglutarate (αKG)-dependent dioxygenase in neurons that converts 5-methyl-dC into 5-hydroxymethyl-dC and further on to 5-formyl- and 5-carboxy-dC. Neurons possess high levels of 5-hydroxymethyl-dC that further increase during neural activity to establish transcriptional plast...

Metabolomics1H-NMR-based metabolomic analysis identifies disrupted glutamate metabolism as distinct serum signature in Parkinson’s disease patients
Using High-Performance Liquid Chromatography, we recently demonstrated a complex dysregulation of the glutamate NMDA receptor-stimulating amino acids in the brain, CSF and serum of Parkinson’s disease (PD) experimental models and patients. Here, we investigate the serum metabolomic profile in the sa...

MetabolomicsGlutamate-mediated metabolic rewiring boosts CpxA/R-OmpF porin and proton motive force to resensitize antibiotic-resistant Escherichia coli to ceftazidime

Ceftazidime (CAZ) is a critically important broad-spectrum antibiotic widely used in clinical practice. However, the rapid emergence of bacterial resistance to CAZ poses a significant challenge in treating infections caused by multidrug-resistant pathogens. In this study, we employed a metabolism...

MetabolomicsExogenous glutamate potentiates gentamicin to kill multidrug- and carbapenem-resistant Pseudomonas aeruginosa through activating biosynthesis of unsaturated fatty acids

Antibiotic-resistant Pseudomonas aeruginosa is a major clinical challenge due to limited drug uptake. This study shows that exogenous glutamate restores gentamicin efficacy by reprogramming bacterial metabolism to enhance membrane permeability. The effect is mediated through increased biosynthesi...

MetabolomicsMetabolomics highlights reduced glutamate and acetylcarnitine in the amniotic fluid of cytomegalovirus-infected pregnant women

Cytomegalovirus (CMV) is a ubiquitous infectious agent that causes significant morbidity in immunosuppressed hosts and is the most common cause of neonatal congenital deafness.An infection acquired during pregnancy can be vertically transmitted to the fetus and cause permanent sequelae in the new...

MetabolomicsGut Microbiota Mediates Maternal PM2.5 Exposure-induced Neurodevelopmental Disorder in offspring via Disturbing the Glutamate Metabolism: Evidence from Multiomics Analysis

While accumulating evidence links maternal PM2.5 exposure to offspring neurodevelopmental impairments, yet the underlying biological pathways require further elucidation. To address this, female ICR mice are exposed to filtered air (FA) or concentrated ambient particulate matter (CAP) for three ...

TranscriptomicsA SUMOylated C-terminus fragment of glutamate transporter EAAT2 linked to inherited ALS mediates motor axon impairment
Downregulation of expression and activity levels of the astroglial glutamate transporter EAAT2 is thought to be implicated in motor neuron excitotoxicity in amyotrophic lateral sclerosis (ALS). We previously reported that EAAT2 is cleaved by caspase-3 at the cytosolic C-terminus domain, impairing th...

TranscriptomicsPolyamines are critical for the induction of the glutamate decarboxylase-dependent acid resistance system in Escherichia coli
As part of our studies on the biological functions of polyamines we have used a mutant of Escherichia coli that lacks all the genes for polyamine biosynthesis for a global transcription analysis on the effect of added polyamines. The most striking early response to polyamine addition is the increase...
