To identify such target genes , we established Egr-1 -overexpressing transfectants from the murine B cell line K46 and from human Ramos B cells .
 ( DNA: target genes, None) , ( cell line: murine B cell line K46, None) , ( cell line: Egr-1 -overexpressing transfectants, None) , ( cell line: human Ramos B cells, None) , ( protein: Egr-1, None)
