The glutamate hypothesis of schizophrenia: evidence from human brain tissue studies.
Review
New
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.
Extensive shift in placental transcriptome profile in preeclampsia and placental origin of adverse pregnancy outcomes.
New
Laan et al., Tartu, Estonia. In Sci Rep, Dec 2014
Using RNASeq, we analyzed differential placental gene expression in cases of normal gestation, late-onset preeclampsia (LO-PE), gestational diabetes (GD) and pregnancies ending with the birth of small-for-gestational-age (SGA) or large-for-gestational-age (LGA) newborns (n = 8/group).
PDZ Domain Recognition: Insight from Human Tax-Interacting Protein 1 (TIP-1) Interaction with Target Proteins.
Review
New
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.
Maternal psychiatric disease and epigenetic evidence suggest a common biology for poor fetal growth.
New
Williams et al., United States. In Bmc Pregnancy Childbirth, Dec 2014
This study group was oversampled for Small-for-Gestational-Age (SGA) infants and excluded Large-for-Gestational-Age (LGA) infants.
Action at a distance: allostery and the development of drugs to target cancer cell metabolism.
Review
New
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.
Impact
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.

GeneRIF
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.
