Turbulence of glutamine metabolism in pan-cancer prognosis and immune microenvironment

Frontiers in Oncology, 2022
IntroductionGlutamine is characterized as the nutrient required in tumor cells. The study based on glutamine metabolism aimed to develop a new predictive factor for pan-cancer prognostic and therapeutic analyses and to explore the mechanisms underlying ...

Oligodendroglioma cells lack glutamine synthetase and are auxotrophic for glutamine, but do not depend on glutamine anaplerosis for growth [PDF]

, 2018
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),

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

Molecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Combining single-cell and transcriptomic analysis revealed the immunomodulatory effect of GOT2 on a glutamine-dependent manner in cutaneous melanoma

Frontiers in Pharmacology, 2023
Background: Reprogramming in glutamine metabolism is a hallmark of cancers, while its role in cutaneous melanoma has not been studied at great length.Methods: Here, we constructed a glutamine metabolism-related prognostic signature in cutaneous melanoma ...

Genes for asparagine metabolism in Lotus japonicus : differential expression and interconnection with photorespiration [PDF]

, 2017
Background: Asparagine is a very important nitrogen transport and storage compound in plants due to its high nitrogen/carbon ratio and stability.

Glutamine Metabolism in Higher Plants

, 1981
Publisher Summary This chapter discusses metabolism and the role of glutamine in the flow of nitrogen. Under certain conditions, all the nitrogen assimilated by bacteria could pass through glutamine. The plant enzyme, in common with that from other sources, exhibits a number of activities that have been the basis of a number of different assays.

CD47 promotes mitogen‐activated protein kinase and epithelial‐to‐mesenchymal transition molecular programs to drive prometastatic phenotypes in non‐small cell lung cancer

Molecular Oncology, EarlyView.
Beyond its role in immune evasion, this study identified that CD47 drives tumor‐intrinsic signaling in non‐small cell lung cancer (NSCLC). Transcriptomic profiling and functional studies revealed that CD47 regulates cell adhesion, migration, and metastasis through an ERK–EMT signaling axis.

Asparagine and Glutamine Metabolism in Chicks

Poultry Science, 1984
In a series of four experiments, asparaginase and glutaminase activity was measured in liver and kidney tissue of 7- to 19-day-old male broiler chicks. In Experiment 1, chicks were fed purified amino acid diets with 14.8 and 44.6% protein equivalents (PE) with 1, 3, or 5% added sodium bicarbonate.
