Notch affects the prodifferentiating effect of retinoic acid and PMA on leukemic cells
Notch proteins determine cell fate decisions in the development of diverse tissues. Notch has been initially found in T-ALL but its role has been also studied in myelopoiesis and myeloid leukemias. Studies in different model systems have led to a widespread controversy as to whether Notch promotes or blocks myeloid differentiation. In this work, we evaluated the influence of Notch activation on leukemic cell differentiation along the monocytic and myelocytic pathway induced by phorbol 12-myristate 13-acetate (PMA) or all-trans retinoic acid (ATRA). We observed that differentiation of the human myeloblastic cell line HL-60 can be retarded or blocked by Delta/Notch interaction. ATRA induces complete remission in patients with acute promyelocytic leukemia, but it cannot completely eliminate the leukemic clone and to be effective it should be combined with chemotherapy. Our findings suggest that Notch signaling may contribute to the incomplete elimination of the leukemic cells after PMA or ATRA treatment and the blockage of Notch pathway may be beneficial in the treatment of myeloid leukemia
