The effect of all-trans Retinoic Acid (RA) on the activity of membrane bound adenylate cyclase (AC) of human malignant cell lines (HL-60 and U-937) was studied. Granulocytic terminal differentiation of the HL-60 cells was correlated to an increase of AC activity and to a potentiation of guanosine 5' triphosphate (GTP) inhibitory effects on the enzyme activity. No direct in vitro effect of RA on HL-60 membranes was found. Monocytic terminal differentiation obtained on 1 B-D arabinofuranosyl cytosine (Ara-C) treated HL-60 cells, or on RA treated U-937 cells, did not modify AC activity. The results here reported suggest relations between the modification of GTP binding protein activity and RA induced granulocytic differentiation of malignant cells.
