Purine nucleotide depletion prompts cell migration by stimulating the serine synthesis pathway
Purine nucleotides are necessary for various biological processes related to cell proliferation. Despite their importance in DNA and RNA synthesis, cellular signaling, and energy-dependent reactions, the impact of changes in cellular purine levels on ...

The interaction of aflatoxins with purines and purine nucleosides [PDF]
From measurements of thermal hyperchromicity and the behaviour of an aflatoxin-DNA mixture on a Sephadex column it was concluded that aflatoxin B(1) is capable of weak binding to single-stranded DNA. The interactions of the aflatoxins (B(1), G(1) and G(2)) with nucleosides result in difference spectra and suggest that the purine bases and the amino ...

The objective was to compare and analyze the relationship between growth, purine content, uric acid, and superoxide dismutase (SOD) in purebred and crossbred Thai native chickens. A total of 300 Thai native chickens were divided into 3 groups.

Evolutionary impacts of purine metabolism genes on mammalian oxidative stress adaptation
Many mammals risk damage from oxidative stress stemming from frequent dives (i.e., cycles of ischemia/reperfusion and hypoxia/reoxygenation), high altitude and subterranean environments, or powered flight.

The influence of the addition of polymers on the physico-chemical properties of bentonite suspensions [PDF]
Bentonite clays have many applications in industries ranging from construction to cosmetics. Addition of polymers can profoundly influence the properties of bentonite suspensions and we now describe the influence of a range of different polymers.

Metabolomics and mass spectrometry imaging reveal channeled de novo purine synthesis in cells
Signs of a metabolon in action Eukaryotic cells have a heterogeneous cytoplasm, with compartments large and small, membrane bound or not. Enzymes that catalyze the de novo synthesis of purine nucleotides, which are needed in rapidly dividing cells, are ...

Purine metabolism regulates DNA repair and therapy resistance in glioblastoma
Intratumoral genomic heterogeneity in glioblastoma (GBM) is a barrier to overcoming therapy resistance. Treatments that are effective independent of genotype are urgently needed.

Cryo-EM structures demonstrate human IMPDH2 filament assembly tunes allosteric regulation
Inosine monophosphate dehydrogenase (IMPDH) mediates the first committed step in guanine nucleotide biosynthesis and plays important roles in cellular proliferation and the immune response. IMPDH reversibly polymerizes in cells and tissues in response to
