MetabolomicsUsing an NMR metabolomics approach to investigate the pathogenicity of amyloid-beta and alpha-synuclein
INTRODUCTION: The pathogenicity at differing points along the aggregation pathway of many fibril-forming proteins associated with neurodegenerative diseases is unclear. Understanding the effect of different aggregation states of these proteins on cellular processes is essential to enhance understand...

MetabolomicsGlobal untargeted serum metabolomic analyses nominate metabolic pathways responsive to loss of expression of the orphan metallo beta-lactamase, MBLAC1
The C. elegans gene swip-10 encodes an orphan metallo beta-lactamase that genetic studies indicate is vital for limiting neuronal excitability and viability. Sequence analysis indicates that the mammalian gene Mblac1 is the likely ortholog of swip-10, with greatest sequence identity localized...

MetabolomicsCDK4/6 inhibitor-mediated cell overgrowth triggers an osmotic stress response and chronic p38MAPK activation to promote long-term cell cycle arrest

Cell size and the cell cycle are intrinsically coupled and abnormal increases in cell size are associated with senescence and permanent cell cycle arrest. The mechanism by which overgrowth primes cells to withdraw from the cell cycle remains unknown. We investigate this here using CDK4/6 inhibito...

MetabolomicsHif1α-Dependent Uncoupling Of Glycolysis Suppresses Tumor Cell Proliferation
Hypoxia-inducible factor-1α (HIF1α) attenuates mitochondrial activity while promoting glycolysis. Paradoxically, it remains unknown why lower glycolysis is compromised in human clear cell renal cell carcinomas (ccRCC), in which HIF1α acts a tumor suppressor by inhibiting cell autonomous proliferatio...

MetabolomicsDistinct metabolic responses of an ovarian cancer stem cell line

Background

Cancer metabolism is emerging as an important focus area in cancer research. However, the in vitro cell culture conditions under which much cellular metabolism research is performed differ drastically from in vivo tumor conditions, which are characterized by variations in the leve...

MetabolomicsA mitochondrial NADPH-cholesterol axis regulates extracellular vesicle biogenesis to support hematopoietic stem cell fate

Mitochondrial fatty acid oxidation (FAO) is essential for hematopoietic stem cell (HSC) self-renewal; however, the mechanism by which mitochondrial metabolism controls HSC fate remains unknown. Here, we show that within the hematopoietic lineage, HSCs have the largest mitochondrial NADPH pools, w...

MetabolomicsHypoxia Dependent Inhibition of Glioblastoma Cell Proliferation, Invasion, and Metabolism by the Choline-Kinase Inhibitor JAS239
Background: Elevated choline kinase alpha (ChoK) levels are observed in most solid tumors, including glioblastomas (GBM), and ChoK inhibitors have demonstrated limited efficacy in GBM models. Given that hypoxia is associated with resistance to GBM therapy, we hypothesized that tumor hypoxia c...

MetabolomicsCell overgrowth potentiates osmotic and replication stresses to promote p38/p53/p21-dependent senescence
Abnormal increases in cell size are associated with senescence and cell cycle exit. The mechanisms by which overgrowth primes cells to withdraw from the cell cycle remain unknown. We address this question using CDK4/6 inhibitors, which arrest cells in G0/G1 and are licensed to treat advanced HR+/HER...

MetabolomicsMetabolic Profiling of Escherichia coli-Based Cell-Free Expression Systems for Process Optimization
Biotechnology has transformed the production of various chemicals and pharmaceuticals due to its efficient and selective processes, but it is inherently limited by its use of live cells as 'biocatalysts.' Cell-free expression (CFE) systems, which use a protein lysate isolated from whole cells, have ...

MetabolomicsA comprehensive metabonomic and transcriptomic analysis reveals how inhibiting glycolysis affects regulatory T cell proliferation

Background: Blocking glycolysis inhibits regulatory T cells (Tregs), which are often hijacked by tumor cells whose survival relies on glycolysis to inhibit antitumor immunity. However, how glycolysis influences Treg proliferation/differentiation remains unclear. Monocarboxylate transporters (MCTs...
