By comparing the expression of genes controlling apoptosis , including those encoding several members of the BCL-2 family of proteins, the known relative resistance of EBV -immortalized B-cell lines to apoptosis induced by low serum was found to correlate with expression of both BCL-2 and A20 .
 ( cell line: EBV -immortalized B-cell lines, None) , ( protein: A20, None) , ( protein: BCL-2 family, None) , ( protein: BCL-2, None)
