By increasing GATA-1 levels via co-transfection , we were able to transactivate the hEpoR promoter in K562 cells and non-erythroid cells , but not in the highly active OCIM1 cells , although GATA-1 mRNA levels were comparable in OCIM1 and K562 .
 ( cell line: OCIM1, None) , ( RNA: GATA-1 mRNA, None) , ( protein: GATA-1, None) , ( cell type: OCIM1 cells, None) , ( cell line: K562 cells, None) , ( cell type: non-erythroid cells, None) , ( cell line: K562, None) , ( protein: GATA-1, None) , ( DNA: hEpoR promoter, None)
