Chen et al., New York City, United States. In Epigenetics, 17 Aug 2015
In this study, we examined the association between the placental expression of 108 established and putative imprinted genes and birth weight in 677 term pregnancies, oversampled for small for gestational age (SGA) and large for gestational age (LGA) infants.
The cpk model of recessive PKD shows glutamine-dependence associated with the production of the oncometabolite 2-hydroxyglutarate.
Weiss et al., Davis, United States. In Am J Physiol Renal Physiol, 08 Aug 2015
In addition, cpk cells require exogenous glutamine for growth such that inhibition of glutaminase-1 decreases cell viability as well as proliferation.

Stefanidis et al., Lárisa, Greece. In Immunology, 04 Aug 2015
Also, IDO or TRP altered the expression of enzymes that control carbon atoms availability for FA synthesis, such as lactate dehydrogenase-A (LDH-A), pyruvate dehydrogenase (PDH), glutaminase 1 (GLS1) and glutaminase 2 (GLS2), in a way that inhibits FA synthesis.
Biochemical, Epigenetic, and Metabolic Approaches to Target IDH Mutations in Acute Myeloid Leukemia.
Emadi et al., Baltimore, United States. In Semin Hematol, 31 Jul 2015
Other therapeutic approaches under preclinical and clinical investigation in this population include DNA methyltransferase inhibitors and agents that target glutamine metabolism through inhibition of glutaminase or depletion of serum glutamine by asparaginase products.
An overview of biological production of L-theanine.
Jiang et al., Wuxi, China. In Biotechnol Adv, May 2015
Four kinds of bacterial enzymes, including L-glutamine synthetase, γ-glutamylmethylamide synthetase, γ-glutamyltranspeptidase, and L-glutaminase, have been characterized to have L-theanine-producing ability.
Sensitization to oxaliplatin in HCT116 and HT29 cell lines by metformin and ribavirin and differences in response to mitochondrial glutaminase inhibition.
Martinez Marignac et al., Argentina. In J Cancer Res Ther, Apr 2015
In addition, both cell lines showed significant differences in response to Compound 968, inhibitor of mitochondrial glutaminase activity.
The glutamate hypothesis of schizophrenia: evidence from human brain tissue studies.
Sweet et al., Morgantown, United States. In Ann N Y Acad Sci, Mar 2015
Studies of the glutamate metabolic pathway have been limited, although there is some evidence that excitatory amino acid transporter-2, glutamine synthetase, and glutaminase have altered expression in schizophrenia.
PDZ Domain Recognition: Insight from Human Tax-Interacting Protein 1 (TIP-1) Interaction with Target Proteins.
Banerjee et al., Stillwater, United States. In Biology (basel), Dec 2014
Human Tax-interacting protein 1 (TIP-1), also known as glutaminase interaction protein (GIP), is a Class I PDZ domain protein that recognizes the consensus binding motif X-S/T-X-V/I/L-COOH of the C-terminus of its target proteins.
Action at a distance: allostery and the development of drugs to target cancer cell metabolism.
Dang et al., Cambridge, United States. In Chem Biol, Oct 2014
We discuss the rationale for developing such drugs and review three targets with central roles in metabolic pathways crucial for cancer cell growth: pyruvate kinase muscle isozyme splice variant 2 (PKM2) in glycolysis, glutaminase in glutaminolysis, and mutations in isocitrate dehydrogenase 1 and 2 isozymes (IDH1/2) in the tricarboxylic acid cycle.
In vivo HIF-mediated reductive carboxylation is regulated by citrate levels and sensitizes VHL-deficient cells to glutamine deprivation.
Iliopoulos et al., United States. In Cell Metab, 2013
Lastly, HIF rendered VHL-deficient cells sensitive to glutamine deprivation in vitro, and systemic administration of glutaminase inhibitors suppressed the growth of RCC cells as mice xenografts.
Structural basis for the allosteric inhibitory mechanism of human kidney-type glutaminase (KGA) and its regulation by Raf-Mek-Erk signaling in cancer cell metabolism.
Sivaraman et al., Singapore, Singapore. In Proc Natl Acad Sci U S A, 2012
KGA activity in cells is stimulated by EGF, and KGA associates with all three kinase components of the Raf-1/Mek2/Erk signaling module.
Synaptic underpinnings of altered hippocampal function in glutaminase-deficient mice during maturation.
Rayport et al., New York City, United States. In Hippocampus, 2012
In wild-type (WT) mice, GLS1 gene expression was highest in the hippocampus and cortex, where it was reduced by about 50% in Glutaminase-deficient mice.
Proteomic analysis identifies dysfunction in cellular transport, energy, and protein metabolism in different brain regions of atypical frontotemporal lobar degeneration.
Bahn et al., Cambridge, United Kingdom. In J Proteome Res, 2012
A protein encoded by this locus was found to be differentially expressed in postmortem brains from patients with atypical frontotemporal lobar degeneration.
The metabolic profile of tumors depends on both the responsible genetic lesion and tissue type.
Bishop et al., San Francisco, United States. In Cell Metab, 2012

Glucose-independent glutamine metabolism via TCA cycling for proliferation and survival in B cells.
Dang et al., Baltimore, United States. In Cell Metab, 2012
The essential role of glutamine metabolism in cell survival and proliferation under hypoxia and glucose deficiency makes them susceptible to the glutaminase inhibitor BPTES and hence could be targeted for cancer therapy.

Data indicate that both HIV-1 infection and IFN-alpha treatment increase glutaminase 1 (GLS1) expression through STAT1 phosphorylation and by binding to the GLS1 promoter.
