MicroRNA-140-5p suppresses invasion and proliferation of glioma cells by targeting glutamate-ammonia ligase (GLUL)

Neoplasma, 2020
Glutamine addiction is a major feature of glioma cells and plays an important role in its growth and proliferation. GLUL (glutamate-ammonia ligase), which catalyzes glutamate and ammonia to synthesize glutamine, plays a crucial role in tumor growth and proliferation.

Central Role of Glutamate Metabolism in the Maintenance of Nitrogen Homeostasis in Normal and Hyperammonemic Brain

Biomolecules, 2016
Glutamate is present in the brain at an average concentration—typically 10–12 mM—far in excess of those of other amino acids. In glutamate-containing vesicles in the brain, the concentration of glutamate may even exceed 100 mM. Yet because glutamate is a

GLUL Confers Perivascular Cancer‐Associated Fibroblasts With Pro‐Angiogenic Capacity to Promote Glioma Progression

Advanced Science
Glioblastoma (GBM) is a malignant brain tumor characterized by profound angiogenic activity and immunosuppressive features. A burgeoning body of research has focused on elucidating the functional effects of stromal cells within the tumor microenvironment

Low Abundance Taxa Show Diverse Microbial Symbiotic Interactions With the Freshwater Sponge, Radiospongilla crateriformis, Pre and Post Gemmulation. [PDF]

Environ Microbiol Rep
The microbiome profile of freshwater sponges did not broadly change in taxonomy or functional profile based on metatranscriptome analysis prior to and after formation of sponge dormant bodies (gemmules). Results highlight a subset of taxa that likely associate with the sponge host in different ways from facultative to long‐term symbionts.

Identification of Blood Pressure-Associated Metabolites by Integrating Metabolomic and Genetic Analysis. [PDF]

MedComm (2020)
This study identified 10 potential causality between metabolites and blood pressure and found potential genetic regulators of two metabolites. Multiomics integration revealed that a genetic variant near the omega‐3 metabolism genes (FADS1/FADS2) may influence blood pressure regulation by modulating prostaglandin E3 levels.

The Urea Carboxylase and Allophanate Hydrolase Activities of Urea Amidolyase Are Functionally Independent [PDF]

, 2016
Urea amidolyase (UAL) is a multifunctional biotin-dependent enzyme that contributes to both bacterial and fungal pathogenicity by catalyzing the ATP-dependent cleavage of urea into ammonia and CO2.

GLUL gene knockdown and restricted glucose level show synergistic inhibitory effect on the luminal subtype breast cancer MCF7 cells’ proliferation and metastasis

EXCLI Journal : Experimental and Clinical Sciences, 2023
The glutamine synthetase path is one of the most important metabolic pathways in luminal breast cancer cells, which plays a critical role in supplying glutamine as an intermediate in the biosynthesis of amino acids and nucleotides.

Glutamine Anabolism Plays a Critical Role in Pancreatic Cancer by Coupling Carbon and Nitrogen Metabolism

Cell Reports, 2019
Summary: Glutamine is thought to play an important role in cancer cells by being deaminated via glutaminolysis to α-ketoglutarate (aKG) to fuel the tricarboxylic acid (TCA) cycle. Supporting this notion, aKG supplementation can restore growth/survival of
