Abstract

The human β-globin gene is expressed - but the human fetal (γ) and embryonic (ε) globin genes are not - in an induced mouse erythroleukemia cell line (M11-X) that contains most of human chromosome 11. A 24-hr exposure of M11-X cells to 5-azacytidine before induction causes 'global' DNA hypomethylation but selective activation of the human γ-globin genes. Genomic DNA is remethylated 2-3 days after exposure to 5-azacytidine, but sequences near the human and mouse globin genes remain hypomethylated, suggesting that the remethylation process is inhibited in these regions.
