Special AT-rich binding protein 1 (SATB1) nuclear protein, expressed predominantly in T cells, regulates genes through targeting chromatin remodeling during T-cell maturation. Here we show SATB1 family protein induction during early human adult erythroid progenitor cell differentiation concomitant with epsilon-globin expression. Erythroid differentiation of human erythroleukemia K562 cells by h...
Mouse models that carry mutations causing thalassemia represent a suitable tool to test in vivo new mutation-specific therapeutic approaches. Transgenic mice carrying the β-globin IVSI-6 mutation (the most frequent in Middle-Eastern regions and recurrent in Italy and Greece) are, at present, not available. We report the production and characterization of a transgenic mouse line (TG-β-IVSI-6) ca...
OBJECTIVE The aim of this study was to determine the laboratory diagnosis and genetic origins of the hemoglobin (Hb) variants, Hb D-Los Angeles and Hb Beograd observed frequently in our region. MATERIAL AND METHODS Hb variants were investigated in one Hb D-Los Angeles and two Hb Beograd families. These families were unrelated with each other. For the determination of Hb variants, alkaline/aci...
Introduction: Among the factors that may be associated with the re-expression gamma-globin in adults is the methylation pattern of the promoter region. The study aimed to determine the association between promoter methylation pattern of the gamma-globin gene in the carriers and affected beta-thalassemia individuals and its expression levels. Methods: This study has been done as a case control-...
The structural and functional conservation of hemoglobin throughout mammals has made the laboratory mouse an exceptionally useful organism in which to study both the protein and the individual globin genes. Early researchers looked to the globin genes as an excellent model in which to examine gene regulation - bountifully expressed and displaying a remarkably consistent pattern of developmental...
background: xmn-1 polymorphism of y g globin gene ( hbg2 ) is a prominent quantitative trait loci (qtl) in β-thalassemia intermediate (β-ti). in current study, we evaluated frequency of xmn-1 polymorphism and its association with β-globin gene ( hbb ) alleles and hb f level in β-ti patients in sistan and balouchestan province, south-east of iran. methods: 45 β-ti patients were enrolled. hbb gen...
Erythropoiesis in the mouse begins with the production of a distinct population of red blood cells in the blood islands of the visceral yolk sac at day 7.5 postcoitum (p.c.). These primitive yolk sac red blood cells are large (about four times the volume of adult erythrocytes), nucleated and produce a distinctive set of embryonic hemoglobins (Craig and Russell, 1964; Russell and Bernstein, 1966...
