Abstract:
:Induction of granulocyte maturation in HL-60 leukemic cells by DMSO (1.2%) or RA (1 microM) is accompanied by a 50-60% decrease in cellular thymidine kinase activity. Similarly, the differentiation of HL-60 cells into monocyte-macrophage phenotype by the addition of PMA is paralleled by a 60-80% suppression of thymidine kinase specific activity. Measurement of thymidine kinase kinetic parameters shows that the Vmax decreases from 0.7 pmol/min in control cells to 0.43 pmol/min in PMA-treated cells and to 0.38 pmol/min in RA-treated cells. The Km of the enzyme is not affected by either inducing agent and remains at 2.1 microM. Studies with PMA analogs suggest that thymidine kinase modulation is coupled to HL-60 differentiation.
