title: Barbiturates enhance retinoic acid or 1,25-dihydroxyvitamin D3-induced differentiation of leukemia HL-60 cells.
abstract: In the presence of 1 nM retinoic acid (RA), pentobarbital markedly enhanced differentiation of HL-60 cells to granulocytic cells. In the absence of RA, pentobarbital by itself did not induce cell differentiation. Similarly, pentobarbital enhanced the action of 1,25-dihydroxyvitamin D3 to induce differentiation of HL-60 cells into monocyte/macrophage lineage. The potency of various barbiturates to enhance cell differentiation was closely correlated with their activity to inhibit protein kinase C of HL-60 cells. In contrast to staurosporine, however, barbiturates did not affect the action of differentiation inducers of other types such as dimethyl sulfoxide, dibutyryl cyclic AMP or actinomycin D.
