To date, good experimental animal models of renal anemia are not available. Therefore, the purpose of this study was to establish a novel approach to induce chronic kidney disease (CKD) with severe anemia by oral administration of adenine in rodents. Adenine was administered to 6-week-old male C57BL/6 mice (25 and 50 mg/kg body weight) by oral gavage daily for 28 days. Serum creatinine and BUN ...

We have investigated the stability of two-dimensional self-assembled molecular networks formed upon co-adsorption of the DNA base, adenine, with each of the amino acids, L-serine and L-tyrosine, on a highly oriented pyrolytic graphite (HOPG) surface by drop-casting from a water solution. L-serine and L-tyrosine were chosen as model systems due to their different interaction with the solvent mol...

The high fluorescence of adenine-containing compounds after reaction with chloroacetaldehyde was used to measure the adenine released from rat liver and Artemia salina ribosomes by the action of ricin A chain and gelonin, two ribosome-inactivating proteins (RIPs) that share the same mechanism of action, consisting in the hydrolysis of the N-glycosidic bond of A-4324 of 28 S rRNA. Two methods we...

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 mdicated by normal levels of adenosine kinase. However. senescent erythrocytes do have decreased levels of adenosine 5’-monophosphate deaminase, the critical enzyme involved in...

The preparation of flavin adenine dinucleotide-aftinity columns employing glucose oxidase and D-amino acid oxidase covalently linked to Sepharose-4B is described. Both immobilized enzymes have very good long-term stabilities, retaining at least half of their original flavin adenine dinucleotide-binding capacity over 11 months. In both cases pure flavin adenine dinucleotide is obtained readily i...
