Our results demonstrate that the altered CCAAT box ( CCAAC ) and the lack of an EKLF binding site in delta-globin contribute to its low level of expression in the hAEC model as well.
 ( cell line: hAEC model, None) , ( protein: delta-globin, None) , ( DNA: CCAAT box, None) , ( DNA: EKLF binding site, None)
