Guanosine regulates adenosine levels in the kidney
In cell culture, extracellular guanosine increases extracellular adenosine by attenuating the disposition of extracellular adenosine (American Journal of Physiology - Cell Physiology 304: C406-C421, 2013). The goal of this investigation was to determine whether this "guanosine-adenosine mechanism" is operative in an intact organ. Twenty-seven isolated, perfused mouse kidneys were subjected to m...
متن کاملExtracellular guanosine regulates extracellular adenosine levels.
The aim of this investigation was to test the hypothesis that extracellular guanosine regulates extracellular adenosine levels. Rat preglomerular vascular smooth muscle cells were incubated with adenosine, guanosine, or both. Guanosine (30 μmol/l) per se had little effect on extracellular adenosine levels. Extracellular adenosine levels 1 h after addition of adenosine (3 μmol/l) were 0.125 ± 0....
متن کاملDueling nucleosides: cross-regulation of extracellular adenosine by guanosine. Focus on "Extracellular guanosine regulates extracellular adenosine levels".
IN ADDITION TO SERVING as components of nucleic acids and central players in intracellular energy metabolism, adenosineand guanosine-based metabolites play critical but distinct roles in signal transduction processes. ATP has two major functions in intracellular signaling. It serves as the principal nucleotide phosphate donor for the myriad protein kinases that act as molecular switches for mos...
متن کاملThe guanosine-adenosine interaction exists in vivo.
In cultured renal cells and isolated perfused kidneys, extracellular guanosine augments extracellular adenosine and inosine (the major renal metabolite of adenosine) levels by altering the extracellular disposition of these purines. The present study addressed whether this "guanosine-adenosine mechanism" exists in vivo. In rats (n = 15), intravenous infusions of adenosine (1 µmol/kg per minute)...
متن کاملAdenosine Triphosphate : Guanosine Monophosphate Phosphotransferase
Several laboratories have reported studies on individual enzymes that belong to the general class of adenosine triphosphate : nucleoside monophosphate phosphotransferases (EC 2.7.4.4), commonly termed nucleoside monophosphate kinases (l-7). Studies with partially purified enzyme preparations have indicated that a variety of nucleoside monophosphates can serve as alternative substrates for nucle...
