Appearance of membrane-bound tyrosine kinase during differentiation of HL-60 leukemia cells by immune interferon and tumor necrosis factor.

The effect of immune interferon (IFN-gamma) and recombinant tumor necrosis factor (rTNF-alpha) on cellular differentiation was investigated in human promyelocytic leukemia cell line HL-60. Both IFN-gamma and rTNF-alpha induced the appearance of the monocytic phenotype in a dose- and time-dependent manner as assessed by morphology, reduction of nitroblue tetrazolium and the induction of alpha-naphthyl butyrate esterase. Utilizing a nondenaturing polyacrylamide electrophoretic assay, it was revealed that a membrane-bound tyrosine kinase activity accompanied the appearance of the differentiated cell type. These results suggest that the induction of membrane-bound tyrosine kinase activity by IFN-gamma and rTNF-alpha may be an important characteristic of monocytic differentiation.[1]
