The human beta-globin gene contains a downstream developmental specific enhancer.
The human beta-globin gene is part of a multigene family and is expressed specifically in adult human erythroid tissue (for review, 1). When the human beta-globin is introduced into fertilized mouse eggs, it is first activated in foetal liver and remains expressed in adult erythroid tissues. It therefore mimicks the pattern of expression of its murine counterpart. It has previously been shown i...
متن کاملHeterozygosis deficit of polymorphic markers linked to the β-globin gene cluster region in the Iranian population
Objective(s): Iran is considered as one of the high-prevalence areas for β-thalassemia with a rate of about 10% carrier frequency. Molecular diagnosis of the disease is performed both by direct sequencing and indirectly by the use of polymorphic markers present in the beta globin gene cluster. However, to date there is no reliable information on the application of the markers in the Iranian pop...
متن کاملβ-globin gene cluster haplotypes in iranian patients with β-thalassemia
introduction: β-globin gene cluster haplotypes are useful in diagnosis of particular molecular defects in β-thalassemia, prenatal diagnosis of β-thalassemia, and elucidating population affinities. methods: β-globin gene cluster haplotypes were studied in 150 β-thalassemia minor and 52 healthy in-dividuals from the fars province of iran. dna was extracted from leukocytes of whole blood by phe-no...
متن کاملThe major regulatory element upstream of the alpha-globin gene has classical and inducible enhancer activity.
A major positive regulatory element has recently been identified 40 kb upstream from the human zeta 2-globin gene. This regulatory element increases the expression of a linked alpha-globin gene in mouse erythroleukemia cells and in transgenic mice. This element has been shown to share many of the structural and functional features of the locus control region (LCR) of the beta-globin gene cluste...
متن کاملa novel single step double positive double negative selection strategy for β-globin gene replacement
introduction: beta thalassemias are a heterogenous group of autosomal recessive disorders, characterized by reduced or absent production of the b-globin chain by the affected allele. transplantation of allogenic hematopoietic stem cells (hsc) is a curative approach but this therapeutic option is not available to the majority of patients. transplantation of genetically corrected autologous hsc i...
