Mammalian erythrocytes are generally thought to lack RNA and therefore to be unable to translate new proteins in response to internal or external signals. Support for this long-standing view has accumulated from diverse studies, most of which have focused on the total content of RNA or the overall level of translation.

THE METABOLISM OF THE ERYTHROCYTE: XIV. METABOLISM OF NUCLEOSIDES BY THE ERYTHROCYTE
Canadian Journal of Biochemistry and Physiology, 1956Adenosine, added to blood, undergoes deamination in the red cells with the formation of inosine. The latter undergoes phosphorolysis to yield hypoxanthine and presumably ribose-1-phosphate. The pentose phosphate is metabolized to lactate yielding ATP in the process. The adenosine deaminase and the purine riboside phosphorylase of the red cell occur in

THE METABOLISM OF THE ERYTHROCYTE: XV. ADENYLATE KINASE OF THE ERYTHROCYTE
Canadian Journal of Biochemistry and Physiology, 1958Adenylate kinase has been found in the membrane and the cytoplasm of rabbit and human erythrocytes. ADP, when added to a suspension of washed erythrocytes, causes an increase in the rate of glucose utilization by the cells. The ADP evidently can enter the cell membrane where it is converted by the adenylate kinase to equimolar quantities of ATP and AMP.

THE METABOLISM OF THE ERYTHROCYTE: X. THE INORGANIC PYROPHOSPHATASE OF THE ERYTHROCYTE
Canadian Journal of Biochemistry and Physiology, 1956The activity of the pyrophosphatase which catalyzes the hydrolysis of inorganic pyrophosphate in the erythrocyte of the human, the rabbit, and the chicken is confined entirely to the cytoplasm of the cell. Following preincubation, the enzyme activity in the human erythrocyte is diminished, but pre-incubation in the presence of cysteine or glutathione ...

THE METABOLISM OF THE ERYTHROCYTE: IX. DIPHOSPHOPYRIDINE NUCLEOTIDASE OF ERYTHROCYTES
Canadian Journal of Biochemistry and Physiology, 1956The rabbit erythrocyte possesses an active DPN-ase which is firmly attached to the membrane of the cell. Evidently, the enzyme is oriented in the membrane in such a way as to be able to act upon DPN added to the external medium. The enzyme splits DPN at the bond linking the quaternary nitrogen of the nicotinamide moiety with the ribose component ...

Journal of Theoretical Biology, 1970
Abstract A structure is proposed, to account for the discoidal shape of the erythrocyte, based on a uniform membrane consisting of rigid-units, probably discs, bonded together by flexible and elastic bonds, at both inner and outer surfaces. The rigid-units are in direct contact and cover the whole surface area.

Nature, 1963
THE camel's ability to live without water for long periods is outstanding1,2,4,6. It can lose about 30 per cent of its body-weight during dehydration in the desert and still move about12. A dehydrated camel can regain its losses of water (about 30 gallons) in about 10 min and resume its normal appearance; despite the large flow of water into the ...

Critical Reviews in Oncology/Hematology, 1990
Two main subjects of erythrocyte rheology, deformation and aggregation, are discussed in detail, on the basis of biochemical structure. The close relationship between the life span (or cell aging) and the rheology of individual erythrocytes is also briefly described.

Biochemistry of the erythrocyte
Experientia, 1969Der Erythrozyt hat zwei Hauptwege fur den Glukoseabbau. Der Emden-Meyerhoff-Weg resultiert in der Phosphorylierung von ADP zu ATP und der Reduktion von NAD+ zu NADH. Der Hexose-Monophosphat-Weg ermoglicht andererseits die Reduktion von NADP+ zu NADPH.

Intravascular thrombus formed under low shear conditions consists of red cells enmeshed within a fibrin network. Since red cells reduce the permeability of fibrin network by surface drag and by volume occupancy the significance of red cell aggregability and deformability in network permeability needs examination.
