Cell-free Hemoglobin Synthesis
A cell-free protein-synthesizing system derived from rabbit reticulocytes is described which is dependent on the addition of transfer RNA for the translation of endogenous hemoglobin messenger RNA. Product analysis indicates that the system is active in the initiation of new chains. When hemoglobin is synthesized in the presence of a limiting amount of tRNA, there is a 50% decrease in (Y chain ...
متن کاملFetal hemoglobin synthesis in erythroid cultures in hereditary persistence of fetal hemoglobin and beta o-thalassemia.
To determine whether hemoglobin regulation is normal in diseases affecting beta-globin gene expression, globin synthesis was examined in members of a family of a patient with hereditary persistence of fetal hemoglobin/beta o-thalassemia (HPFH/beta o-thal). The HPFH defect is the Ghanian type II, with a deletion from psi beta 1 to at least 20 kb 3' to beta. The beta o-thal gene has the haplotype...

متن کاملGlobin chain synthesis in the marrow and reticulocytes of beta thalassemia, hemoglobin H disease, and beta delta thalassemia.
a, fi, and ‘i globin chain synthesis in bone marrow and peripheral blood reticulocytes were studied in two patients with thalassemia major, two with thalassemia intermedia, one with thaIassemia minor, one with Hb H disease, and one with homozygous f38-thalassemia. Nine nonthalassemic patients served as controls. In thalassemia major, a marked imbalance of ato fichain synthesis was found in the ...
