Effects of guanine nucleotides on cns neuropeptide receptors

Journal of Supramolecular Structure and Cellular Biochemistry, 1981
AbstractThe effect of nucleotides on central nervous system neuropeptide receptor binding was investigated. The guanine nucleotides, guanosine‐5′‐triphosphate and guanylyl‐5′‐imidodiphosphate, significantly inhibited the binding of radiolabeled vasoactive intestinal polypeptide but not that of [Tyr4]bombesin to rat brain membranes.

Dual regulation of ACTH secretion by guanine nucleotides in permeabilized AtT-20 cells

Cellular and Molecular Neurobiology, 1988
1. We have examined the effects of guanine nucleotides on ACTH secretion from digitonin-permeabilized AtT-20 cells, with the aim of analyzing the involvement of GTP-binding proteins (G proteins) in the secretory process. 2.

Fibres of Guanine Nucleosides and Nucleotides

Nature, 1963
IT has been shown by Gellert, Lipsett and Davies1 that guanylic acid will form a gel under certain pH conditions and they were able to draw fibres from gels of the disodium salt of 3′-guanylic acid and of the free acid, 5′-guanosine monophosphate. From X-ray diffraction studies of these fibres the foregoing workers concluded that they consisted of a ...

pH-Dependent Perturbation of Ras−Guanine Nucleotide Interactions and Ras Guanine Nucleotide Exchange

Biochemistry, 2004
p21Ras (Ras) proteins cycle between active GTP-bound and inactive GDP-bound states to mediate signal transduction pathways that promote cell growth, differentiation, and apoptosis. To better understand how cellular regulatory factors, such as guanine nucleotide exchange factors (GEFs) and nitric oxide (NO), modulate Ras-guanine nucleotide binding ...

Guanine nucleotides are present in human CSF

NeuroReport, 1997
Several studies have shown that experimentally added guanine nucleotides (GN) may extracellularly modulate the glutamatergic system. However, there is no previous report of the extracellular occurrence of GN in the CNS. This study used HPLC to investigate the presence of GN in cerebrospinal fluid (CSF) samples of 26 patients.

Inhibition of neutrophil migration by guanine nucleotides

Agents and Actions, 1991
Guanine nucleotides have, besides an activating effect on exocytosis and respiratory burst in permeabilized neutrophils, a modulating effect on some functions in intact neutrophils. We investigated the effect of guanine nucleotides on fMet-Leu-Phe-induced migration of rabbit neutrophils using the Boyden chamber technique. GTP gave a moderate inhibition
