We reported previously that treatment with all-trans retinoic acid (ATRA) and granulocyte macrophage colony-stimulating factor (GM-CSF) induces differentiation of human myeloblastic leukemia ML-1 cells to granulocytes, whereas treatment with ATRA alone induces practically no differentiation of these cells.
In this study, we investigated telomerase activity and expression of genes involved in telomerase activity in human myeloblastic leukemia ML-1 cells, differentiated synergistically by treatment with all-trans retinoic acid (ATRA) and granulocyte-macrophage colony-stimulating factor (GM-CSF).
