Accordingly, we studied the role of NF-kappaB in germline Cepsilon transcription by using two human Burkitt's lymphoma B cell lines , DND39 and DG75 .
 ( cell line: DND39, None) , ( cell line: DG75, None) , ( DNA: germline, None) , ( protein: NF-kappaB, None) , ( cell line: human Burkitt#$%#s lymphoma B cell lines, None)
