Previous studies demonstrated that the rabbit beta-globin gene is transcribed from its own promoter and regulated as a herpes simplex virus (HSV) early gene following insertion into the early HSV thymidine kinase gene in the intact viral genome (J. R. Smiley, C. Smibert, and R. D. Everrett, J. Virol. 61:2368-2377, 1987). We report here that the beta-globin promoter remained under early control ...

We have isolated the delta-globin gene of the New-World spider monkey, Ateles geoffroyi, and compared its nucleotide sequence with those of other primate delta- and beta-globin genes. Among primate delta-globin genes, the rate of nonsynonymous substitutions is much less than the rate of synonymous substitutions. This suggests that primate delta-globin genes may remain under evolutionary conserv...

A Spanish male patient with beta-thalassaemia major was studied. Compound heterozygosity was found for one of the most common beta-globin gene mutations in the Spanish population (codon 39 C --> T) and for a mutation in the TATA box element of the beta-globin gene promoter (-28 A --> C mutation). To our knowledge this is the first report of a CD39 C --> T and -28 A --> C change association and ...

AIMS To investigate whether it is worthwhile, in areas where thalassaemia is common, to screen for globin gene mutations in subjects with a mean corpuscular volume (MCV) above 80 fL, especially in partners of known thalassaemia carriers. METHODS Blood samples from 95 subjects with MCV between 80 and 85 fL were screened for the presence of alpha globin gene mutations and the haemoglobin (Hb) E...

The development and evaluation of drugs to elevate fetal hemoglobin in the treatment of the genetic diseases of hemoglobin would be facilitated by the availability of reliable cell assays. We have used real-time, quantitative polymerase chain reaction (PCR) analyses of globin messenger RNA (mRNA) levels in a biphasic, erythropoietin-dependent primary culture system for human adult erythroid cel...

Patients affected by beta-thalassemia major require lifelong transfusions because of insufficient or absent production of the beta chain of hemoglobin (Hb). A minority of patients are cured by allogeneic bone marrow transplantation. In the most severe of the hitherto available mouse models of beta-thalassemia, a model for human beta-thalassemia intermedia, we previously demonstrated that globin...

BACKGROUND AND OBJECTIVE Current application of molecular biology techniques to the study of the DNA of globin genes has confirmed the existence of silent alpha and beta thalassemias; which had already been reported on the basis of red blood cell parameters and family studies. The present work was aimed at analyzing all the aspects of the phenotype of the most common varieties of silent thalass...
