PYCR1 inhibition in bone marrow stromal cells enhances bortezomib sensitivity in multiple myeloma cells by altering their metabolism

Molecular Oncology, EarlyView.
This study investigated how PYCR1 inhibition in bone marrow stromal cells (BMSCs) indirectly affects multiple myeloma (MM) cell metabolism and viability. Culturing MM cells in conditioned medium from PYCR1‐silenced BMSCs impaired oxidative phosphorylation and increased sensitivity to bortezomib.

The intracellular location of nitrogen metabolism enzymes in Pisum arvense L. roots

Acta Societatis Botanicorum Poloniae, 2014
The time course changes of nitrate assimilation enzymes and their distribution has been studied in Pisum arvense roots. The results indicate that nitrate reductase (EC 1.6.6.2) and glutamine synthetase (EC 6.3.1.2) are present in the soluble fraction ...

Patient‐specific pharmacogenomics demonstrates xCT as predictive therapeutic target in colon cancer with possible implications in tumor connectivity

Molecular Oncology, EarlyView.
This study integrates transcriptomic profiling of matched tumor and healthy tissues from 32 colorectal cancer patients with functional validation in patient‐derived organoids, revealing dysregulated metabolic programs driven by overexpressed xCT (SLC7A11) and SLC3A2, identifying an oncogenic cystine/glutamate transporter signature linked to ...

Geographic and climatic differentiation of electrophoretic forms of esterase, glutamate dehydrogenase and peroxidase in Scots pine tissues

Acta Societatis Botanicorum Poloniae, 2014
The enzymatic systems have been investigated in individual trees derived from 17 distant localities in Europe and Asia. Esterase and glutamate dehydrogenase polymorphism was determined in extracts from mixture of 50 macrogametophytes, iperoxidase ...

The role of glutamine oxoglutarate aminotransferase and glutamate dehydrogenase in nitrogen metabolism in Mycobacterium bovis BCG. [PDF]

PLoS ONE, 2013
Recent evidence suggests that the regulation of intracellular glutamate levels could play an important role in the ability of pathogenic slow-growing mycobacteria to grow in vivo.

Ketogenic diet in action: Metabolic profiling of pyruvate dehydrogenase deficiency

Molecular Genetics and Metabolism Reports, 2023
The pyruvate dehydrogenase complex serves as the main connection between cytosolic glycolysis and the tricarboxylic acid cycle within mitochondria. An infant with pyruvate dehydrogenase complex deficiency was treated with vitamin B1 supplementation and a

Peroxidasin enables melanoma immune escape by inhibiting natural killer cell cytotoxicity

Molecular Oncology, EarlyView.
Peroxidasin (PXDN) is secreted by melanoma cells and binds the NK cell receptor NKG2D, thereby suppressing NK cell activation and cytotoxicity. PXDN depletion restores NKG2D signaling and enables effective NK cell–mediated melanoma killing. These findings identify PXDN as a previously unrecognized immune evasion factor and a potential target to improve

A glutamate dehydrogenase gene sequence [PDF]

Nucleic Acids Research, 1989
A Chlorella sorokiniana genomic DNA library was screened with a NADP-specific glutamate dehydrogenase (GDH) cDNA. Two putative GDH sequences were isolated. One sequence is typically eukaryotic in that its coding region is interrupted by many introns (1). Southern blots showed that C.

Inhibition of the mitochondrial pyruvate carrier protects from excitotoxic neuronal death. [PDF]

, 2017
Glutamate is the dominant excitatory neurotransmitter in the brain, but under conditions of metabolic stress it can accumulate to excitotoxic levels.
