Abstract

We studied the ability of inducers and inhibitors of erythroid differentiation of K562 leukemia cells, such as sodium butyrate, dimethyl sulfoxide, and phorbol-12-myristate-13-acetate, respectively, to modulate sensitivity of these cells to nonspecific lysis (nonrestricted with respect to antigens of the major histocompatibilty complex) mediated by natural human or rat killer cells. Unfractionated leukocytes from human peripheral blood or rat splenocytes were used as sources of natural killers. The induction of erythroid differentiation by sodium butyrate was accompanied by a significant increase in cell sensitivity to lysis with human peripheral blood lymphocytes; incubation of K562 cells in the mixture of sodium butyrate and dimethyl sulfoxide did not change cell sensitivity to lysis by both types of effector cells. The inhibition of sodium butyrate-induced erythroid differentiation with high doses of phorbol-12-myristate-13-acetate (100 nM; incubation was in the presence of both these agents simultaneously) resulted in an increased cell sensitivity to lysis with rat splenocytes. Incubation of K562 cells in a mixture of sodium butyrate, dimethyl sulfoxide, and phorbol-12-myristate-13-acetate (100 nM) produced greater lysis by human leukocytes, as compared with incubation in the mixture of sodium butyrate and dimethyl sulfoxide.
