introduction: stress has many effects on the development of systems and organs in the fetal period, and these effects appear after birth. since hemopoietic system is susceptible to stress, effects of restraint stress were studied in offspring of pregnant rats. methods: pregnant rats were divided into one control and three stress groups. the control group did not receive any stress during the ge...
Anemia of chronic disease is a multifactorial disorder, resulting mainly from inflammation-driven reticuloendothelial iron retention, impaired erythropoiesis, and reduced biological activity of erythropoietin. Erythropoiesis-stimulating agents have been used for the treatment of anemia of chronic disease, although with varying response rates and potential adverse effects. Serum concentrations o...
The variety of patients with thalassemia in Thailand offers an opportunity to fully characterize the kinetic causes of the anemia and to study apoptosis of marrow erythroid precursors as a possible factor contributing to its severity. Kinetic studies showed that in hemoglobin H (HbH) disease, the extent of hemolysis, as well as the minimally ineffective erythropoiesis, usually falls within the ...
BACKGROUND TAM receptors (Tyro3, Axl and Mer) are expressed in hematopoietic tissues. The roles of the three receptors in hematopoiesis are, however, largely unknown. We investigated the role of TAM receptors in regulating erythropoiesis. DESIGN AND METHODS Single and double mutant mice for Axl and Mer were used in the study. Cellularity of bone marrow and spleen, hematologic parameters, flow...
AIMS β-Thalassemia is a common inherited red cell disorder characterized by ineffective erythropoiesis and severe oxidative stress. Peroxiredoxin-2 (Prx2), a typical 2-cysteine peroxiredoxin, is upregulated during β-thalassemic erythropoiesis, but its contribution to stress erythropoiesis, a common feature of thalassemia, is yet to be fully defined. RESULTS Here, we showed that Prx2(-/-) mice...
Measurements of erythropoiesis and iron balance were made in eight normal and 32 anemic subjects. The latter consisted of 12 individuals with ineffective erythropoiesis (beta-thalassemia/hemoglobin E), 13 subjects with ineffective erythropoiesis and hemolytic anemia (hemoglobin H), and seven subjects with hemolytic anemia (hereditary spherocytosis). A consistent relationship within each group e...
