Neurotrophic Effects of Extracellular Guanosine

Nucleosides, Nucleotides and Nucleic Acids, 2008
Central nervous system (CNS) astrocytes release guanosine extracellularly, that exerts trophic effects. In CNS, extracellular guanosine (GUO) stimulates mitosis, synthesis of trophic factors, and cell differentiation, including neuritogenesis, is neuroprotective, and reduces apoptosis due to several stimuli.

Metabolism of Guanosine in Human Erythrocytes

Vox Sanguinis, 1985
Abstract. The metabolism of guanosine in human erythrocytes has been studied in two different experimental systems – direct incubation and dialysis incubation – the latter allowing continuous addition and removal of substances. Intra‐ and extracellular purine compounds were analyzed using high‐performance liquid chromatography (HPLC).

Self-assembly of guanosine and deoxy-guanosine into hydrogels: monovalent cation guided modulation of gelation, morphology and self-healing properties.

Journal of materials chemistry. B, 2014
In this study, we report the effect of monovalent cations including Na+, K+, Rb+, Ag+, Au+, Tl+, Hg+ and NH4 + on the stimulation of purine nucleosides guanosine (G) and deoxy-guanosine (dG) to self-assemble into hydrogels.

Role of substrates and products of PI 3-kinase in regulating activation of Rac-related guanosine triphosphatases by Vav.

Science, 1998
Mitogen stimulation of cytoskeletal changes and c-jun amino-terminal kinases is mediated by Rac small guanine nucleotide-binding proteins. Vav, a guanosine diphosphate (GDP)-guanosine triphosphate (GTP) exchange factor for Rac that stimulates the ...

Enhancing the Mechanical Properties of Guanosine-Based Supramolecular Hydrogels with Guanosine-Containing Polymers

, 2014
We demonstrate that multivalent, polymeric 8-methoxyguanosine derivatives based on poly(dimethylacrylamide) can enhance the mechanical properties of the low molecular weight hydrogelator 8-methoxy-2′,3′,5′-tri-O-acetylguanosine at biologically relevant ...
