Brief periods of stimulation of the preganglionic nerve fibers produced a severalfold increase in the content of adenosine 3',5'-monophosphate in superior cervical sympathetic ganglia, whereas postganglionic stimulation did not. These and other experiments indicated that the increased concentrations of adenosine 3'5'-monophosphate were closely associated with the process of synaptic transmissio...

Senescent erythrocytes from rabbits were previously shown to have elevated levels of adenine nucleotides. The present study documents that aged red blood cells have a normal synthetic capacity for adenine nucleotides, as indicated by normal levels of adenosine kinase. However, senescent erythrocytes do have decreased levels of adenosine 5'-monophosphate deaminase, the critical enzyme involved i...

Controlling axon and dendrite elongation is critical in developing precise neural circuits. Using isolated cultures of dentate granule neurons, we established an experimental system that can simultaneously monitor the behaviors of axonal and dendritic outgrowth. Our previous study shows that axons and dendrites respond differentially to manipulated cyclic adenosine monophosphate signaling, but ...

Plant ribonucleic acids which have high adenosine monophosphate concentrations were studied. Purified deoxyribonucleic acid-like ribonucleic acid and tenaciously bound ribonucleic acid fractions both contained poly-adenosine monophosphate sequences (those from the latter being longer than those from the former); without these poly-adenosine monophosphate sequences their base compositions were t...

A method for the routine determination of 5'-mononucleotides (uridine 5'-monophosphate, inosine 5'-monophosphate, adenosine 5'-monophosphate, guanosine 5'-monophosphate, and cytidine 5'-monophosphate) in infant formula and adult nutritionals is described. After sample dissolution and addition of internal standard, potential interferences were removed by anion-exchange SPE followed by HPLC-UV an...

Natural killer (NK) cell activity is inhibited by the adenosine analogue tubercidin (Tub) and stimulated by the deoxyadenosine analogue 2-fluorol-/9-r>-arabinofuranosyladenine S'-monophosphate (F-ara-AMP) in the spleen lymphocytes from mice treated with the drugs in vivo (T. Priebe et al.. Cancer Res., 48: 4799, 1988). The present report demonstrates that the inhibition by Tub and stimulation b...
