Many genes whose transcription is erythroid-specific contain enhancer or promoter elements that bind the transcription factor NF-E2. Hemin induction increases the expression of globin genes in the human erythroleukemia cell line K562, and increases the expression of reporters gene regulated by an enhancer elements containing binding sites for NF-E2. The failure of metalloporphyrins other than hemin to stimulate the transient expression of a CAT reporter gene linked to an enhancer element containing a binding site for NF-E2 was correlated with their failure to induce benzidine-positive K562 cells and increase the steady-state level of gamma-globin mRNA. This study suggests that elevated levels of zinc protoporphyrin IX found in the anemia of chronic disease, iron deficiency, and lead poisoning may contribute to a decrease in globin gene expression by interfering with the transcriptional activity of enhancer elements containing binding sites for NF-E2.
