Glutamine Metabolism Is Required for Alveolar Regeneration during Lung Injury

open access: yesBiomolecules, 2022
(1) Background: Abnormal repair after alveolar epithelial injury drives the progression of idiopathic pulmonary fibrosis (IPF). The maintenance of epithelial integrity is based on the self-renewal and differentiation of alveolar type 2 (AT2) cells, which

GOLM1 Stimulation of Glutamine Metabolism Promotes Osteoporosis via Inhibiting Osteogenic Differentiation of BMSCs

open access: yesCellular Physiology and Biochemistry, 2018
Background/Aims: Bone marrow mesenchymal stem cells (BMSCs) play an essential role in osteoporosis. However, the molecular mechanisms and the involvement of glutamine metabolism in osteogenic BMSCs differentiation and osteoporosis remain largely unclear.

Inhibition of lncRNA NEAT1 induces dysfunction of fibroblast-like synoviocytes in rheumatoid arthritis via miRNA-338-3p-mediated regulation of glutamine metabolism

open access: yesJournal of Orthopaedic Surgery and Research, 2022
Background Rheumatoid arthritis (RA) is a systemic chronic autoimmune disease; cellular glutamine metabolism in fibroblast-like synoviocytes (FLSs) of RA was known to be essential for RA pathogenesis and progression.

Increased Ammonium Toxicity in Response to Exogenous Glutamine in Metastatic Breast Cancer Cells

open access: yesMetabolites, 2022
Several cancers, including breast cancers, show dependence on glutamine metabolism. The purpose of the present study was to determine the mechanistic basis and impact of differential glutamine metabolism in nonmetastatic and metastatic murine mammary ...

Deficient astrocyte metabolism impairs glutamine synthesis and neurotransmitter homeostasis in a mouse model of Alzheimer's disease

open access: yesNeurobiology of Disease, 2021
Alzheimer's disease (AD) leads to cerebral accumulation of insoluble amyloid-β plaques causing synaptic dysfunction and neuronal death. Neurons rely on astrocyte-derived glutamine for replenishment of the amino acid neurotransmitter pools.

Glutamine Metabolism in Brain Tumors [PDF]

open access: yesCancers, 2019
Altered metabolism is a hallmark of cancer cells. Tumor cells rewire their metabolism to support their uncontrolled proliferation by taking up nutrients from the microenvironment. The amino acid glutamine is a key nutrient that fuels biosynthetic processes including ATP generation, redox homeostasis, nucleotide, protein, and lipid synthesis.

Visualization of glutamine transporter activities in living cells using genetically encoded glutamine sensors. [PDF]

open access: yesPLoS ONE, 2012
Glutamine plays a central role in the metabolism of critical biological molecules such as amino acids, proteins, neurotransmitters, and glutathione. Since glutamine metabolism is regulated through multiple enzymes and transporters, the cellular glutamine

GLUTAMINE METABOLISM OF THE BEET [PDF]

open access: yesPlant Physiology, 1936
Although glutamine has long been known as a plant constituent (10), the relationship of this amide to the nitrogen metabolism of the plant has seldom been subjected to direct test. The close analogy in chemical structure with asparagine and the similarity of the conditions under which the respective amides are found have led to the view, early ...
