N-Acetylaspartate Improves Cell Survival When Glucose is Limiting [PDF]

SSRN Electronic Journal, 2020
SummaryN-acetylasparate (NAA), previously considered a brain-specific metabolite, is found in several cancers. However, whether it plays a role in tumor growth or survival is not fully understood. We provide evidence that NAA prevents cell death in low-glucose conditions via sustaining intracellular UDP-N-acetylglucosamine (UDP-GlcNac) levels ...

Understanding Further the Phenotypic Spectrum of Central Nervous System Inflammatory Demyelinating Disorders Using Unsupervised Clustering

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Central nervous system (CNS) inflammatory demyelinating syndromes, including multiple sclerosis (MS), aquaporin‐4 antibody–positive neuromyelitis optica spectrum disorder (AQP4 + NMOSD), and myelin oligodendrocyte glycoprotein (MOG) antibody–associated disease (MOGAD), occasionally overlap.

Cortical Glutamate and GABA Changes During Early Abstinence in Alcohol Dependence and Their Associations With Benzodiazepine Medication

Frontiers in Psychiatry, 2021
In this report, we present cross-sectional and longitudinal findings from single-voxel MEGA-PRESS MRS of GABA as well as Glu, and Glu + glutamine (Glx) concentrations in the ACC of treatment-seeking alcohol-dependent patients (ADPs) during detoxification

Effect of metabotropic glutamate receptor 3 genotype on N-acetylaspartate levels and neurocognition in non-smoking, active alcoholics [PDF]

, 2012
BACKGROUND: We studied the effects of single nucleotide polymorphisms (SNPs) in the metabotropic glutamate receptor 3 (GRM3) gene on brain N-acetylaspartate (NAA) concentrations and executive function (EF) skills in non-smoking, active alcoholics, and ...

Design of Optical Transducer for Recognition of Biomolecular Interactions between Bacterial Lipopolysaccharides and Amino Acids

Advanced Science, EarlyView.
A deep comprehension of biomolecular phenomena at interfaces is significant with their fundamental and practical importance. Our experimental and theoretical investigations reveal that specific amino acids (glutamic acid and aspartic acid) exhibit an orientational coupling with liquid crystals, which can recognize and optically report the interfacial ...

Metabolite differences between glutamate carboxypeptidase II gene knockout mice and their wild-type littermates after traumatic brain injury: a 7-tesla 1H-MRS study

BMC Neuroscience, 2018
Background Traumatic brain injury (TBI) is a complex condition and remains a prominent public and medical health issue in individuals of all ages. A rapid increase in extracellular glutamate occurs after TBI, leading to glutamate-induced excitotoxicity ...

N-acetylaspartate complexes with calcium and lanthanide ions

Journal of Inorganic Biochemistry, 1995
N-acetylaspartate (NAA) is the one of the most prominent resonances observed in the solvent-suppressed NMR spectrum of the human brain. Although it is present in the brain at about 10 mM, its precise metabolic function is still unclear, We have examined the NAA as a potential chelator for divalent metal ions such as Ca2+.

Relapses, Comorbidities, and Predictors of Outcome in Anti‐GABAA Receptor Encephalitis

Annals of Neurology, EarlyView.
Objectives To characterize the magnetic resonance imaging (MRI) lesion dynamics, comorbidities, predictors of relapse, and outcomes in anti‐γ‐aminobutyric acid type A receptor (GABAAR) encephalitis, and assess the utility of LIM‐domain‐only‐protein 5 (LMO5) antibodies as tumor markers.
