The anti-apoptotic Bcl-2 proteins regulate lymphocyte survival and are over-expressed in lymphoid malignancies, including chronic lymphocytic leukemia (CLL). The small molecule inhibitor ABT-737 binds with high affinity to Bcl-2, Bcl-xl, and Bcl-w but with low affinity to Mcl-1, Bfl-1, and Bcl-b. The active analog of ABT-737, navitoclax, has shown a high therapeutic index in lymphoid malignancies developing a predictive marker for it would be clinically valuable for patient selection or choice of drug combinations. We compared expression of anti-apoptotic Bcl-2 genes that are known to be targeted by ABT-737. Our findings reveal that the relative ratio of Mcl-1 and Bfl-1 …
