Hepatic endothelial Alk1 signaling protects from development of vascular malformations while maintaining organ‐specific endothelial differentiation and angiocrine portmanteau of the names Wingless and Int‐1 signaling. Abstract Background and Aims In hereditary hemorrhagic telangiectasia (HHT), severe liver vascular malformations are associated with ...

Glutamine versus ammonia utilization in the NAD synthetase family. [PDF]
NAD is a ubiquitous and essential metabolic redox cofactor which also functions as a substrate in certain regulatory pathways. The last step of NAD synthesis is the ATP-dependent amidation of deamido-NAD by NAD synthetase (NADS).

Leukemia Cells Resistant to Glutamine Deprivation Express Glutamine Synthetase Protein
Objective: Low glutamine levels have been shown in tumor environments for several cancer subtypes. Therefore, it has been suggested that cancer cells rewire their metabolism to adopt low nutrient levels for survival and proliferation.

Oligodendroglioma cells lack glutamine synthetase and are auxotrophic for glutamine, but do not depend on glutamine anaplerosis for growth [PDF]
In cells derived from several types of cancer, a transcriptional program drives high consumption of glutamine (Gln), which is used for anaplerosis, leading to a metabolic addiction for the amino acid. Low or absent expression of Glutamine Synthetase (GS),

Oligodendrocytes Support Neuronal Glutamatergic Transmission via Expression of Glutamine Synthetase
Summary: Glutamate has been implicated in a wide range of brain pathologies and is thought to be metabolized via the astrocyte-specific enzyme glutamine synthetase (GS).

Glutamine Synthetase and Glutamine Synthetase‐Like Protein from Human Brain [PDF]
Abstract: Glutamine synthetase (GS; EC 6.3.1.2), a key enzyme ofglutamate metabolism, and another enzyme possessing highhydroxylamine‐L‐glutamine transferase activity comparable to that of GS andtermed GS‐like protein (GSLP) were purified from human brain concurrently.

In vitro suppression of inflammatory cytokine response by methionine sulfoximine
Background The glutamine synthetase inhibitor methionine sulfoximine (MSO), shown previously to prevent death caused by an inflammatory liver response in mice, was tested on in vitro production of cytokines by mouse peritoneal macrophages triggered with ...

Glutamate is the main excitatory amino acid acting at the level of pre and postsynaptic neurons, as well as in glial cells. It is involved in the coordinated modulation of energy metabolism, glutamine synthesis, and ammonia detoxification.

Orthotopic liver transplantation for urea cycle enzyme deficiency [PDF]
Hyperammonemia, abnormalities in plasma amino acids and abnormalities of standard liver functions were corrected by orthotopic liver transplantation in a 14‐day‐old boy with carbamyl phosphate synthetase‐I deficiency and in a 35‐yr‐old man with ...
