DNA sequences required for regulated expresson of the β-globin genes in murine erythroleukaemia cells.
Philosophical Transactions: Biological Sciences , Volume 307 p. 271- 282
We have introduced into murine erythroleukaemia (MEL) cells a series of human globin gene cosmids and two sets of hybrid genes constructed from the human beta-globin gene and the human gamma-globin or murine H-2Kbm1 genes. S1-nuclease analysis of the mRNA products from these genes before and after MEL cell differentiation showed that the human beta-globin gene, but not the human epsilon- or gamma-globin or H-2Kbm1 genes, is induced specifically. Hybrid genes containing human beta-globin DNA sequences from either 5' or 3' side of the translation initiation site were both inducible. Measurement of the relative rate of transcription showed this induction to be the result of transcriptional activation. We therefore suggest that DNA sequences which regulate beta-globin gene expression during MEL differentiation are located both 5' and 3' to the translation initiation site.
