Energy metabolism in adenosine deaminase-inhibited human erythrocytes. 1986

H A Buc, and L Thuillier, and M Hamet, and F Garreau, and A Moncion, and J L Pérignon

The metabolic changes induced by the deoxycoformycin inhibition of adenosine deaminase were studied in human erythrocytes incubated with nucleosides. 1 Adenosine nucleotide levels and glycolytic rate were increased by adenosine. 2 With deoxyadenosine, the cellular ATP level was reduced when dATP increased and the glycolytic rate was similarly enhanced. 3 The hypoxanthine production was equivalent in both cases. Our data demonstrate that human red cells are able to catabolize adenine deoxynucleotides into hypoxanthine, and the control of energy metabolism is not impaired by adenosine deaminase inhibition when PO identical to 4 and NAD+ are not limiting.

UI MeSH Term Description Entries

D006019 Glycolysis A metabolic process that converts GLUCOSE into two molecules of PYRUVIC ACID through a series of enzymatic reactions. Energy generated by this process is conserved in two molecules of ATP. Glycolysis is the universal catabolic pathway for glucose, free glucose, or glucose derived from complex CARBOHYDRATES, such as GLYCOGEN and STARCH.

D000241 Adenosine A nucleoside that is composed of ADENINE and D-RIBOSE. Adenosine or adenosine derivatives play many important biological roles in addition to being components of DNA and RNA. Adenosine itself is a neurotransmitter. Adenocard,Adenoscan
