Acute myeloid leukemia (AML) is a hard-to-treat cancer in which certain leukemia stem/progenitor cells (LSPCs) hide in the bone marrow and resist treatment. Researchers led by Michael Andreeff, M.D., Ph.D., and Yuki Nishida, M.D., Ph.D., examined valemetostat, which targets EZH1 and EZH2 – proteins linked to keeping these LSPCs dormant. While valemetostat alone does not directly fight leukemia, it can wake up hidden LSPCs, making them vulnerable to chemotherapy. In lab models, researchers demonstrated that valemetostat improved the activity...
