Published: 1 April 2010
...Aqsa Malik; Leslie Thomas Buck SUMMARY Adenosine has been termed a retaliatory metabolite and its neuroprotective effects have been implicated in the hypoxia tolerance of several species; however, its role in the invertebrate CNS remains unclear. To determine if adenosine modulates neuronal...

...L. G. Eckerle; M. Lucassen; T. Hirse; H. O. Pörtner SUMMARY Exposure of ectothermic organisms to variations in temperatures causes a transient mismatch between energy supply and demand, which needs to be compensated for during acclimation. Adenosine accumulation from ATP breakdown indicates...

... at high concentrations. The effects of 5-HT were blocked by methysergide. In the prometamorphic tadpole, ATP elicited relaxation that was blocked by the ectonucleotidase inhibitor ARL67156 and the adenosine A 1 receptor antagonist 1,3-dipropyl-8-cyclopentylxanthine (DPCPX), suggesting adenosine...

...Gereon Maurer; Jerrel L. Wilkens; Manfred K. Grieshaber SUMMARY As shown previously, adenosine and the adenine nucleotides cause a rapid increase in heart rate ( f H ) and haemolymph velocity( v HL ) when infused into intact American lobster( Homarus americanus ). Here we compare the effects...

...T. J. MacCormack; W. R. Driedzic SUMMARY Adenosine is a product of adenylate phosphate breakdown that can exert protective effects on tissues during energy limitation. Accumulation of cardiac adenosine under hypoxia is well documented in mammals but has not been shown in fish. Adenosine content...

... connected to a SMART system. Analysis of the purified active fraction by mass spectrometry demonstrated the presence of adenosine as the single organic compound in the extract that had a stimulatory effect on Na + transport. In a separate series of experiments, we confirmed that 1 μmol l -1 adenosine had...

... of tissues we tested ATP and adenosine for their effects on epithelial transport. Examination of integuments from pondwater- and high-salinity-adapted leeches revealed different sensitivities for these purines. Apical and basolateral application of ATP both stimulated transepithelial Na + uptake and I ami...

... in extracellular [K + ] during the initial phase of anoxic depolarization. However, unlike the anoxia-tolerant turtle brain, adenosine did not appear to be involved in the downregulation of K + leakage in the frog brain. The increased anoxia-tolerance of the frog brain is thought to be a matter more of slow death...
