Inborn defects in the antioxidant systems of human red blood cells.

Electronic address: r.vanzwieten@sanquin.nl.2Department of Medical Biochemistry, Academic Medical Center, University of Amsterdam, Amsterdam, The Netherlands.3Laboratory of Red Blood Cell Diagnostics, Department of Blood Cell Research, Sanquin Blood Supply Organization, 1066 CX Amsterdam, The Netherlands.AbstractRed blood cells (RBCs) contain large amounts of iron and operate in highly oxygenated tissues. As a result, these cells encounter a continuous oxidative stress. Protective mechanisms against oxidation include prevention of formation of reactive oxygen species (ROS), scavenging of various forms of ROS, and repair of oxidized cellular contents. In general, a partial defect in any of these systems can harm RBCs and promote senescence, but is without chronic hemolytic complaints. In this review we summarize the often rare inborn defects that interfere with the various protective mechanisms present in RBCs. NADPH is the main source of reduction equivalents in RBCs, used by most of the protective systems. When NADPH becomes limiting, red cells are prone to being damaged. In many of the severe RBC enzyme deficiencies, a lack of protective enzyme activity is frustrating erythropoiesis or is not restricted to RBCs. Common hereditary RBC disorders, such as thalassemia, sickle-cell trait, and unstable hemoglobins, give rise to increased oxidative stress caused by free heme and iron generated from hemoglobin. The beneficial effect of thalassemia minor, sickle-cell trait, and glucose-6-phosphate dehydrogenase deficiency on survival of malaria infection may well be due to the shared feature of enhanced oxidative stress. This may inhibit parasite growth, enhance uptake of infected RBCs by spleen macrophages, and/or cause less cytoadherence of the infected cells to capillary endothelium.

Novel type of red blood cell pyruvate kinase hyperactivity predicts a remote regulatory locus involved in PKLR gene expression.

van Oirschot BA, Francois JJ, van Solinge WW, van Wesel AC, Rijksen G, van Amstel HK, van Wijk R.Author information Department of Clinical Chemistry and Hematology, University Medical Center Utrecht, Utrecht, TheNetherlands.AbstractRed blood cell pyruvate kinase (PK-R) is a key regulatory enzyme of red cell metabolism. Hereditary deficiency of PK-R is caused by mutations in the PKLR gene, leading to chronic nonspherocytic hemolytic anemia. In contrast to PK deficiency, inherited PK hyperactivity has also been described. This very rare abnormality of RBC metabolism has been documented in only two families and appears to be without clinical consequences. Thus far, it has been attributed to either a gain of function mutation in PKLR or to persistent expression of the fetal PK isozyme PK-M2 in mature red blood cells. We here report on a novel type of inherited PK hyperactivity that is characterized by solely increased expression of a kinetically normal PK-R. In line with the latter, no mutations were detected in PKLR. Mutations in regulatory regions as well as variations in PKLR copy number were also absent. In addition, linkage analysis suggested that PK hyperactivity segregated independently from the PKLR locus. We therefore postulate that the causative mutation resides in a novel yet-unidentified locus, and upregulates PKLR gene expression. Other mutations of the same locus may be involved in those cases of PK deficiency that fail to reveal mutations in PKLR.
