In order to understand the relationship, if any, between expression of GATA-1 , response to Epo and erythroid differentiation , we analyzed the expression of GATA-1 , Epo-R and globin genes in an Epo-dependent human cell line, UT-7 Epo.
 ( protein: Epo-R, None) , ( DNA: globin genes, None) , ( protein: GATA-1, None) , ( protein: GATA-1, None) , ( cell line: UT-7, None)
