STAT1 and acute myeloid leukemia: Unlike MDMs, the enhanced expression of CYLD by fludarabine or STAT1 silencing only affected FITC-dextran uptake and the phagocytosis of leukemic cells and unaltered maturation and cytokine productions of BMDMs from AML patients, although knockdown of STAT1 by fludarabine or STAT1 siRNA induced the apoptosis of all MDMs and BMDMs.
