Resistance Mechanisms Underlying Venetoclax Resistance In Mantle Cell Lymphoma

Background: BCL-2 is highly expressed in mantle cell lymphoma (MCL), and targeting BCL-2 with venetoclax (ABT-199) has resulted in positive clinical outcomes in MCL patients. However, resistance to various targeted agents often emerges; therefore, we generated venetoclax-resistant MCL cell lines to uncover the mechanisms mediating acquired venetoclax resistance and performed high-throughput drug screening to identify novel anti-MCL agents that can overcome venetoclax resistance.
