Leukemia Cells Resistant to Glutamine Deprivation Express Glutamine Synthetase Protein
Turkish Journal of Hematology, 2022 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.

In vitro suppression of inflammatory cytokine response by methionine sulfoximine
Journal of Inflammation, 2018 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 ...

Role of glutamine synthetase in angiogenesis beyond glutamine synthesis [PDF]
Nature, 2018 Glutamine synthetase, encoded by the gene GLUL, is an enzyme that converts glutamate and ammonia to glutamine. It is expressed by endothelial cells, but surprisingly shows negligible glutamine-synthesizing activity in these cells at physiological glutamine levels.

Outgrowth of Rice Tillers Requires Availability of Glutamine in the Basal Portions of Shoots
Rice, 2018 Background Our previous studies concluded that metabolic disorder in the basal portions of rice shoots caused by a lack of cytosolic glutamine synthetase1;2 (GS1;2) resulted in a severe reduction in the outgrowth of tillers.

The Rhizobium GstI Protein Reduces the NH4+ Assimilation Capacity of Rhizobium leguminosarum
Molecular Plant-Microbe Interactions, 2001 We show that the protein encoded by the glutamine synthetase translational inhibitor (gstI) gene reduces the NH4+ assimilation capacity of Rhizobium leguminosarum.
