On the other hand, MCL-1 is important for the regulatory T cell population, and GX15-070 (a pan inhibitor of MCL-1/BCL-2/BCL-XL/BCL-W/BFL-1) preferentially induces cell death in the regulatory T cell population and enhanced clearance of lung cancer cells when combined with vaccine78,79. The gene discussed is BCL2; the disease is lung carcinoma.
