Treatment of beta-thalassemia with hydroxyurea (HU)--effects of HU on globin gene expression
1Shanghai Institute of Medical Genetics, Shanghai Children's Hospital, PRC.
Abstract:
A newly developed method of RT-PCR/competitive PCR for measuring the relative and absolute content of globin mRNAs as well as micro-globin chain biosynthetic assay have been used to study the alterations of globin gene expressions in the patients with beta-thalassemia pre- and post-hydroxyurea (HU) treatment. It was found for the first time that HU had the effect of enhancing beta-globin gene expression in some patients. Two cases with beta-thalassemia who were subjected to HU treatment for over two years showed a marked increase in beta-globin mRNA level and beta-globin chain synthesis, resulting in more effective erythropoiesis and the alleviation of clinical symptoms.

01:31Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
