Optimal Fluxes, Reaction Replaceability, and Response to Enzymopathies in the Human Red Blood Cell
Characterizing the capabilities, key dependencies, and response to perturbations of genome-scale metabolic networks is a basic problem with important applications. A key question concerns the identification of the potentially most harmful reaction knockouts. The integration of combinatorial methods with sampling techniques to explore the space of viable flux states may provide crucial insights ...
متن کاملRed cell enzymopathies in the newborn. I. Evaluation of red cell metabolism.
In order to evaluate properly red cell metabolic data obtained in newborns with congenital hemolytic disorders, the unique metabolic characteristics and normal developmental changes that occur prenatally and postnatally are presented. The age-dependent red cell glycolytic enzymes (hexokinase, aldolase, pyruvate kinase) and glucose-6-phosphate dehydrogenase and most glycolytic intermediates are ...
متن کاملRed cell enzymopathies in the newborn. II. Inherited deficiencies of red cell enzymes.
The mature, anueleate human red cell is incapable of synthesizing en zymes and is dependent upon anaerobic metabolism to m eet its energy requirements. Thus, inherited red cell enzyme deficiencies of the glycolytic pathway often result in chronic nonspherocytic hemolytic anemia (CNSHA). The hexosemonophosphate (HMP) shunt is normally relatively inactive and enzyme deficiences, such as G-6-PD d...
متن کاملRed blood cell vesiculation in hereditary hemolytic anemia
Hereditary hemolytic anemia encompasses a heterogeneous group of anemias characterized by decreased red blood cell survival because of inherited membrane, enzyme, or hemoglobin disorders. Affected red blood cells are more fragile, less deformable, and more susceptible to shear stress and oxidative damage, and show increased vesiculation. Red blood cells, as essentially all cells, constitutively...
متن کاملAlterations of red blood cell metabolome in overhydrated hereditary stomatocytosis.
Overhydrated hereditary stomatocytosis, clinically characterized by hemolytic anemia, is a rare disorder of the erythrocyte membrane permeability to monovalent cations, associated with mutations in the Rh-associated glycoprotein gene. We assessed the red blood cell metabolome of 4 patients with this disorder and showed recurrent metabolic abnormalities associated with this disease but not due t...
