title: Modulation of c-myc expression in the HL-60 cell line.
abstract: A decrease in the expression of the myc proto-oncogene of HL-60 cells has been reported as an accompaniment of myeloid differentiation induced by either dimethylsulfoxide or retinoic acid. We report herein that several inhibitors of poly(ADP-ribose)-polymerase induced myeloid differentiation in HL-60 cultures. Studies on the expression of the c-myc gene in total cell RNA populations indicate that expression of this gene is inversely correlated with the state of differentiation, either myeloid or monocytic, of the cultured cells independent of the inducer and the rate of cell proliferation.
