Inhibiting PI3Kγ in acute myeloid leukemia.

The mainly hematologic expression profile of phosphatidylinositol-3-kinase-γ (PI3Kγ) makes it an attractive therapeutic target. Recent work from three independent groups shows that inhibiting PI3Kγ impairs the metabolism and growth of acute myeloid leukemia cells — a finding that justifies further mechanistic and clinical exploration.
